+
+AsyncKit provides harness for `parallel` and `serial` iterators over list of items represented by arrays or objects.
+Optionally it accepts abort function (should be synchronously return by iterator for each item), and terminates left over jobs upon an error event. For specific iteration order built-in (`ascending` and `descending`) and custom sort helpers also supported, via `asynckit.serialOrdered` method.
+
+It ensures async operations to keep behavior more stable and prevent `Maximum call stack size exceeded` errors, from sync iterators.

+
+
+## Install
+
+```sh
+$ npm install --save asynckit
+```
+
+## Examples
+
+### Parallel Jobs
+
+Runs iterator over provided array in parallel. Stores output in the `result` array,
+on the matching positions. In unlikely event of an error from one of the jobs,
+will terminate rest of the active jobs (if abort function is provided)
+and return error along with salvaged data to the main callback function.
+
+#### Input Array
+
+```javascript
+var parallel = require('asynckit').parallel
+  , assert   = require('assert')
+  ;
+
+var source         = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+  , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+  , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
+  , target         = []
+  ;
+
+parallel(source, asyncJob, function(err, result)
+{
+  assert.deepEqual(result, expectedResult);
+  assert.deepEqual(target, expectedTarget);
+});
+
+// async job accepts one element from the array
+// and a callback function
+function asyncJob(item, cb)
+{
+  // different delays (in ms) per item
+  var delay = item * 25;
+
+  // pretend different jobs take different time to finish
+  // and not in consequential order
+  var timeoutId = setTimeout(function() {
+    target.push(item);
+    cb(null, item * 2);
+  }, delay);
+
+  // allow to cancel "leftover" jobs upon error
+  // return function, invoking of which will abort this job
+  return clearTimeout.bind(null, timeoutId);
+}
+```
+
+More examples could be found in [test/test-parallel-array.js](test/test-parallel-array.js).
+
+#### Input Object
+
+Also it supports named jobs, listed via object.
+
+```javascript
+var parallel = require('asynckit/parallel')
+  , assert   = require('assert')
+  ;
+
+var source         = { first: 1, one: 1, four: 4, sixteen: 16, sixtyFour: 64, thirtyTwo: 32, eight: 8, two: 2 }
+  , expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
+  , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
+  , expectedKeys   = [ 'first', 'one', 'two', 'four', 'eight', 'sixteen', 'thirtyTwo', 'sixtyFour' ]
+  , target         = []
+  , keys           = []
+  ;
+
+parallel(source, asyncJob, function(err, result)
+{
+  assert.deepEqual(result, expectedResult);
+  assert.deepEqual(target, expectedTarget);
+  assert.deepEqual(keys, expectedKeys);
+});
+
+// supports full value, key, callback (shortcut) interface
+function asyncJob(item, key, cb)
+{
+  // different delays (in ms) per item
+  var delay = item * 25;
+
+  // pretend different jobs take different time to finish
+  // and not in consequential order
+  var timeoutId = setTimeout(function() {
+    keys.push(key);
+    target.push(item);
+    cb(null, item * 2);
+  }, delay);
+
+  // allow to cancel "leftover" jobs upon error
+  // return function, invoking of which will abort this job
+  return clearTimeout.bind(null, timeoutId);
+}
+```
+
+More examples could be found in [test/test-parallel-object.js](test/test-parallel-object.js).
+
+### Serial Jobs
+
+Runs iterator over provided array sequentially. Stores output in the `result` array,
+on the matching positions. In unlikely event of an error from one of the jobs,
+will not proceed to the rest of the items in the list
+and return error along with salvaged data to the main callback function.
+
+#### Input Array
+
+```javascript
+var serial = require('asynckit/serial')
+  , assert = require('assert')
+  ;
+
+var source         = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+  , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+  , expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
+  , target         = []
+  ;
+
+serial(source, asyncJob, function(err, result)
+{
+  assert.deepEqual(result, expectedResult);
+  assert.deepEqual(target, expectedTarget);
+});
+
+// extended interface (item, key, callback)
+// also supported for arrays
+function asyncJob(item, key, cb)
+{
+  target.push(key);
+
+  // it will be automatically made async
+  // even it iterator "returns" in the same event loop
+  cb(null, item * 2);
+}
+```
+
+More examples could be found in [test/test-serial-array.js](test/test-serial-array.js).
+
+#### Input Object
+
+Also it supports named jobs, listed via object.
+
+```javascript
+var serial = require('asynckit').serial
+  , assert = require('assert')
+  ;
+
+var source         = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+  , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+  , expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
+  , target         = []
+  ;
+
+var source         = { first: 1, one: 1, four: 4, sixteen: 16, sixtyFour: 64, thirtyTwo: 32, eight: 8, two: 2 }
+  , expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
+  , expectedTarget = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+  , target         = []
+  ;
+
+
+serial(source, asyncJob, function(err, result)
+{
+  assert.deepEqual(result, expectedResult);
+  assert.deepEqual(target, expectedTarget);
+});
+
+// shortcut interface (item, callback)
+// works for object as well as for the arrays
+function asyncJob(item, cb)
+{
+  target.push(item);
+
+  // it will be automatically made async
+  // even it iterator "returns" in the same event loop
+  cb(null, item * 2);
+}
+```
+
+More examples could be found in [test/test-serial-object.js](test/test-serial-object.js).
+
+_Note: Since _object_ is an _unordered_ collection of properties,
+it may produce unexpected results with sequential iterations.
+Whenever order of the jobs' execution is important please use `serialOrdered` method._
+
+### Ordered Serial Iterations
+
+TBD
+
+For example [compare-property](compare-property) package.
+
+### Streaming interface
+
+TBD

+
+## Installing
+
+### Package manager
+
+Using npm:
+
+```bash
+$ npm install axios
+```
+
+Using bower:
+
+```bash
+$ bower install axios
+```
+
+Using yarn:
+
+```bash
+$ yarn add axios
+```
+
+Using pnpm:
+
+```bash
+$ pnpm add axios
+```
+
+Once the package is installed, you can import the library using `import` or `require` approach:
+
+```js
+import axios, {isCancel, AxiosError} from 'axios';
+```
+
+You can also use the default export, since the named export is just a re-export from the Axios factory:
+
+```js
+import axios from 'axios';
+
+console.log(axios.isCancel('something'));
+````
+
+If you use `require` for importing, **only default export is available**:
+
+```js
+const axios = require('axios');
+
+console.log(axios.isCancel('something'));
+```
+
+For cases where something went wrong when trying to import a module into a custom or legacy environment,
+you can try importing the module package directly:
+
+```js
+const axios = require('axios/dist/browser/axios.cjs'); // browser commonJS bundle (ES2017)
+// const axios = require('axios/dist/node/axios.cjs'); // node commonJS bundle (ES2017)
+```
+
+### CDN
+
+Using jsDelivr CDN (ES5 UMD browser module):
+
+```html
+<script src="https://cdn.jsdelivr.net/npm/axios@1.6.7/dist/axios.min.js"></script>
+```
+
+Using unpkg CDN:
+
+```html
+<script src="https://unpkg.com/axios@1.6.7/dist/axios.min.js"></script>
+```
+
+## Example
+
+> **Note**: CommonJS usage  
+> In order to gain the TypeScript typings (for intellisense / autocomplete) while using CommonJS imports with `require()`, use the following approach:
+
+```js
+import axios from 'axios';
+//const axios = require('axios'); // legacy way
+
+// Make a request for a user with a given ID
+axios.get('/user?ID=12345')
+  .then(function (response) {
+    // handle success
+    console.log(response);
+  })
+  .catch(function (error) {
+    // handle error
+    console.log(error);
+  })
+  .finally(function () {
+    // always executed
+  });
+
+// Optionally the request above could also be done as
+axios.get('/user', {
+    params: {
+      ID: 12345
+    }
+  })
+  .then(function (response) {
+    console.log(response);
+  })
+  .catch(function (error) {
+    console.log(error);
+  })
+  .finally(function () {
+    // always executed
+  });
+
+// Want to use async/await? Add the `async` keyword to your outer function/method.
+async function getUser() {
+  try {
+    const response = await axios.get('/user?ID=12345');
+    console.log(response);
+  } catch (error) {
+    console.error(error);
+  }
+}
+```
+
+> **Note**: `async/await` is part of ECMAScript 2017 and is not supported in Internet
+> Explorer and older browsers, so use with caution.
+
+Performing a `POST` request
+
+```js
+axios.post('/user', {
+    firstName: 'Fred',
+    lastName: 'Flintstone'
+  })
+  .then(function (response) {
+    console.log(response);
+  })
+  .catch(function (error) {
+    console.log(error);
+  });
+```
+
+Performing multiple concurrent requests
+
+```js
+function getUserAccount() {
+  return axios.get('/user/12345');
+}
+
+function getUserPermissions() {
+  return axios.get('/user/12345/permissions');
+}
+
+Promise.all([getUserAccount(), getUserPermissions()])
+  .then(function (results) {
+    const acct = results[0];
+    const perm = results[1];
+  });
+```
+
+## axios API
+
+Requests can be made by passing the relevant config to `axios`.
+
+##### axios(config)
+
+```js
+// Send a POST request
+axios({
+  method: 'post',
+  url: '/user/12345',
+  data: {
+    firstName: 'Fred',
+    lastName: 'Flintstone'
+  }
+});
+```
+
+```js
+// GET request for remote image in node.js
+axios({
+  method: 'get',
+  url: 'https://bit.ly/2mTM3nY',
+  responseType: 'stream'
+})
+  .then(function (response) {
+    response.data.pipe(fs.createWriteStream('ada_lovelace.jpg'))
+  });
+```
+
+##### axios(url[, config])
+
+```js
+// Send a GET request (default method)
+axios('/user/12345');
+```
+
+### Request method aliases
+
+For convenience, aliases have been provided for all common request methods.
+
+##### axios.request(config)
+##### axios.get(url[, config])
+##### axios.delete(url[, config])
+##### axios.head(url[, config])
+##### axios.options(url[, config])
+##### axios.post(url[, data[, config]])
+##### axios.put(url[, data[, config]])
+##### axios.patch(url[, data[, config]])
+
+###### NOTE
+When using the alias methods `url`, `method`, and `data` properties don't need to be specified in config.
+
+### Concurrency (Deprecated)
+Please use `Promise.all` to replace the below functions.
+
+Helper functions for dealing with concurrent requests.
+
+axios.all(iterable)
+axios.spread(callback)
+
+### Creating an instance
+
+You can create a new instance of axios with a custom config.
+
+##### axios.create([config])
+
+```js
+const instance = axios.create({
+  baseURL: 'https://some-domain.com/api/',
+  timeout: 1000,
+  headers: {'X-Custom-Header': 'foobar'}
+});
+```
+
+### Instance methods
+
+The available instance methods are listed below. The specified config will be merged with the instance config.
+
+##### axios#request(config)
+##### axios#get(url[, config])
+##### axios#delete(url[, config])
+##### axios#head(url[, config])
+##### axios#options(url[, config])
+##### axios#post(url[, data[, config]])
+##### axios#put(url[, data[, config]])
+##### axios#patch(url[, data[, config]])
+##### axios#getUri([config])
+
+## Request Config
+
+These are the available config options for making requests. Only the `url` is required. Requests will default to `GET` if `method` is not specified.
+
+```js
+{
+  // `url` is the server URL that will be used for the request
+  url: '/user',
+
+  // `method` is the request method to be used when making the request
+  method: 'get', // default
+
+  // `baseURL` will be prepended to `url` unless `url` is absolute.
+  // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs
+  // to methods of that instance.
+  baseURL: 'https://some-domain.com/api/',
+
+  // `transformRequest` allows changes to the request data before it is sent to the server
+  // This is only applicable for request methods 'PUT', 'POST', 'PATCH' and 'DELETE'
+  // The last function in the array must return a string or an instance of Buffer, ArrayBuffer,
+  // FormData or Stream
+  // You may modify the headers object.
+  transformRequest: [function (data, headers) {
+    // Do whatever you want to transform the data
+
+    return data;
+  }],
+
+  // `transformResponse` allows changes to the response data to be made before
+  // it is passed to then/catch
+  transformResponse: [function (data) {
+    // Do whatever you want to transform the data
+
+    return data;
+  }],
+
+  // `headers` are custom headers to be sent
+  headers: {'X-Requested-With': 'XMLHttpRequest'},
+
+  // `params` are the URL parameters to be sent with the request
+  // Must be a plain object or a URLSearchParams object
+  params: {
+    ID: 12345
+  },
+  
+  // `paramsSerializer` is an optional config that allows you to customize serializing `params`. 
+  paramsSerializer: {
+
+    //Custom encoder function which sends key/value pairs in an iterative fashion.
+    encode?: (param: string): string => { /* Do custom operations here and return transformed string */ }, 
+    
+    // Custom serializer function for the entire parameter. Allows user to mimic pre 1.x behaviour.
+    serialize?: (params: Record<string, any>, options?: ParamsSerializerOptions ), 
+    
+    //Configuration for formatting array indexes in the params. 
+    indexes: false // Three available options: (1) indexes: null (leads to no brackets), (2) (default) indexes: false (leads to empty brackets), (3) indexes: true (leads to brackets with indexes).    
+  },
+
+  // `data` is the data to be sent as the request body
+  // Only applicable for request methods 'PUT', 'POST', 'DELETE , and 'PATCH'
+  // When no `transformRequest` is set, must be of one of the following types:
+  // - string, plain object, ArrayBuffer, ArrayBufferView, URLSearchParams
+  // - Browser only: FormData, File, Blob
+  // - Node only: Stream, Buffer, FormData (form-data package)
+  data: {
+    firstName: 'Fred'
+  },
+
+  // syntax alternative to send data into the body
+  // method post
+  // only the value is sent, not the key
+  data: 'Country=Brasil&City=Belo Horizonte',
+
+  // `timeout` specifies the number of milliseconds before the request times out.
+  // If the request takes longer than `timeout`, the request will be aborted.
+  timeout: 1000, // default is `0` (no timeout)
+
+  // `withCredentials` indicates whether or not cross-site Access-Control requests
+  // should be made using credentials
+  withCredentials: false, // default
+
+  // `adapter` allows custom handling of requests which makes testing easier.
+  // Return a promise and supply a valid response (see lib/adapters/README.md).
+  adapter: function (config) {
+    /* ... */
+  },
+
+  // `auth` indicates that HTTP Basic auth should be used, and supplies credentials.
+  // This will set an `Authorization` header, overwriting any existing
+  // `Authorization` custom headers you have set using `headers`.
+  // Please note that only HTTP Basic auth is configurable through this parameter.
+  // For Bearer tokens and such, use `Authorization` custom headers instead.
+  auth: {
+    username: 'janedoe',
+    password: 's00pers3cret'
+  },
+
+  // `responseType` indicates the type of data that the server will respond with
+  // options are: 'arraybuffer', 'document', 'json', 'text', 'stream'
+  //   browser only: 'blob'
+  responseType: 'json', // default
+
+  // `responseEncoding` indicates encoding to use for decoding responses (Node.js only)
+  // Note: Ignored for `responseType` of 'stream' or client-side requests
+  // options are: 'ascii', 'ASCII', 'ansi', 'ANSI', 'binary', 'BINARY', 'base64', 'BASE64', 'base64url',
+  // 'BASE64URL', 'hex', 'HEX', 'latin1', 'LATIN1', 'ucs-2', 'UCS-2', 'ucs2', 'UCS2', 'utf-8', 'UTF-8',
+  // 'utf8', 'UTF8', 'utf16le', 'UTF16LE'
+  responseEncoding: 'utf8', // default
+
+  // `xsrfCookieName` is the name of the cookie to use as a value for xsrf token
+  xsrfCookieName: 'XSRF-TOKEN', // default
+
+  // `xsrfHeaderName` is the name of the http header that carries the xsrf token value
+  xsrfHeaderName: 'X-XSRF-TOKEN', // default
+    
+  // `undefined` (default) - set XSRF header only for the same origin requests
+  withXSRFToken: boolean | undefined | ((config: InternalAxiosRequestConfig) => boolean | undefined),
+
+  // `onUploadProgress` allows handling of progress events for uploads
+  // browser & node.js
+  onUploadProgress: function ({loaded, total, progress, bytes, estimated, rate, upload = true}) {
+    // Do whatever you want with the Axios progress event
+  },

+  // Use `false` to disable proxies, ignoring environment variables.
+  // `auth` indicates that HTTP Basic auth should be used to connect to the proxy, and

+  // If the proxy server uses HTTPS, then you must set the protocol to `https`.

+  ]
+}
+```
+
+## Response Schema
+
+The response for a request contains the following information.
+
+```js
+{
+  // `data` is the response that was provided by the server
+  data: {},
+
+  // `status` is the HTTP status code from the server response
+  status: 200,
+
+  // `statusText` is the HTTP status message from the server response
+  statusText: 'OK',
+
+  // `headers` the HTTP headers that the server responded with
+  // All header names are lowercase and can be accessed using the bracket notation.
+  // Example: `response.headers['content-type']`
+  headers: {},
+
+  // `config` is the config that was provided to `axios` for the request
+  config: {},
+
+  // `request` is the request that generated this response
+  // It is the last ClientRequest instance in node.js (in redirects)
+  // and an XMLHttpRequest instance in the browser
+  request: {}
+}
+```
+
+When using `then`, you will receive the response as follows:
+
+```js
+axios.get('/user/12345')
+  .then(function (response) {
+    console.log(response.data);
+    console.log(response.status);
+    console.log(response.statusText);
+    console.log(response.headers);
+    console.log(response.config);
+  });
+```
+
+When using `catch`, or passing a [rejection callback](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/then) as second parameter of `then`, the response will be available through the `error` object as explained in the [Handling Errors](#handling-errors) section.
+
+## Config Defaults
+
+You can specify config defaults that will be applied to every request.
+
+### Global axios defaults
+
+```js
+axios.defaults.baseURL = 'https://api.example.com';
+
+// Important: If axios is used with multiple domains, the AUTH_TOKEN will be sent to all of them.
+// See below for an example using Custom instance defaults instead.
+axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;
+
+axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
+```
+
+### Custom instance defaults
+
+```js
+// Set config defaults when creating the instance
+const instance = axios.create({
+  baseURL: 'https://api.example.com'
+});
+
+// Alter defaults after instance has been created
+instance.defaults.headers.common['Authorization'] = AUTH_TOKEN;
+```
+
+### Config order of precedence
+
+Config will be merged with an order of precedence. The order is library defaults found in [lib/defaults.js](https://github.com/axios/axios/blob/master/lib/defaults/index.js#L28), then `defaults` property of the instance, and finally `config` argument for the request. The latter will take precedence over the former. Here's an example.
+
+```js
+// Create an instance using the config defaults provided by the library
+// At this point the timeout config value is `0` as is the default for the library
+const instance = axios.create();
+
+// Override timeout default for the library
+// Now all requests using this instance will wait 2.5 seconds before timing out
+instance.defaults.timeout = 2500;
+
+// Override timeout for this request as it's known to take a long time
+instance.get('/longRequest', {
+  timeout: 5000
+});
+```
+
+## Interceptors
+
+You can intercept requests or responses before they are handled by `then` or `catch`.
+
+```js
+// Add a request interceptor
+axios.interceptors.request.use(function (config) {
+    // Do something before request is sent
+    return config;
+  }, function (error) {
+    // Do something with request error
+    return Promise.reject(error);
+  });
+
+// Add a response interceptor
+axios.interceptors.response.use(function (response) {
+    // Any status code that lie within the range of 2xx cause this function to trigger
+    // Do something with response data
+    return response;
+  }, function (error) {
+    // Any status codes that falls outside the range of 2xx cause this function to trigger
+    // Do something with response error
+    return Promise.reject(error);
+  });
+```
+
+If you need to remove an interceptor later you can.
+
+```js
+const myInterceptor = axios.interceptors.request.use(function () {/*...*/});
+axios.interceptors.request.eject(myInterceptor);
+```
+
+You can also clear all interceptors for requests or responses.
+```js
+const instance = axios.create();
+instance.interceptors.request.use(function () {/*...*/});
+instance.interceptors.request.clear(); // Removes interceptors from requests
+instance.interceptors.response.use(function () {/*...*/});
+instance.interceptors.response.clear(); // Removes interceptors from responses
+```
+
+You can add interceptors to a custom instance of axios.
+
+```js
+const instance = axios.create();
+instance.interceptors.request.use(function () {/*...*/});
+```
+
+When you add request interceptors, they are presumed to be asynchronous by default. This can cause a delay
+in the execution of your axios request when the main thread is blocked (a promise is created under the hood for
+the interceptor and your request gets put on the bottom of the call stack). If your request interceptors are synchronous you can add a flag
+to the options object that will tell axios to run the code synchronously and avoid any delays in request execution.
+
+```js
+axios.interceptors.request.use(function (config) {
+  config.headers.test = 'I am only a header!';
+  return config;
+}, null, { synchronous: true });
+```
+
+If you want to execute a particular interceptor based on a runtime check,
+you can add a `runWhen` function to the options object. The interceptor will not be executed **if and only if** the return
+of `runWhen` is `false`. The function will be called with the config
+object (don't forget that you can bind your own arguments to it as well.) This can be handy when you have an
+asynchronous request interceptor that only needs to run at certain times.
+
+```js
+function onGetCall(config) {
+  return config.method === 'get';
+}
+axios.interceptors.request.use(function (config) {
+  config.headers.test = 'special get headers';
+  return config;
+}, null, { runWhen: onGetCall });
+```
+
+### Multiple Interceptors
+
+Given you add multiple response interceptors
+and when the response was fulfilled
+- then each interceptor is executed
+- then they are executed in the order they were added
+- then only the last interceptor's result is returned
+- then every interceptor receives the result of its predecessor
+- and when the fulfillment-interceptor throws
+    - then the following fulfillment-interceptor is not called
+    - then the following rejection-interceptor is called
+    - once caught, another following fulfill-interceptor is called again (just like in a promise chain).
+
+Read [the interceptor tests](./test/specs/interceptors.spec.js) for seeing all this in code.
+
+## Error Types
+
+There are many different axios error messages that can appear that can provide basic information about the specifics of the error and where opportunities may lie in debugging.
+
+The general structure of axios errors is as follows:
+| Property  | Definition  |
+| -------- | ----------  |
+| message  | A quick summary of the error message and the status it failed with. |
+| name     | This defines where the error originated from. For axios, it will always be an 'AxiosError'. |
+| stack    | Provides the stack trace of the error. | 
+| config   | An axios config object with specific instance configurations defined by the user from when the request was made |
+| code     | Represents an axios identified error. The table below lists out specific definitions for internal axios error.  |
+| status   | HTTP response status code. See [here](https://en.wikipedia.org/wiki/List_of_HTTP_status_codes) for common HTTP response status code meanings. 
+
+Below is a list of potential axios identified error
+| Code  |  Definition   |
+| -------- | ----------  |
+| ERR_BAD_OPTION_VALUE | Invalid or unsupported value provided in axios configuration. |
+| ERR_BAD_OPTION | Invalid option provided in axios configuration. |
+| ECONNABORTED | Request timed out due to exceeding timeout specified in axios configuration. |
+| ETIMEDOUT | Request timed out due to exceeding default axios timelimit. |
+| ERR_NETWORK | Network-related issue.
+| ERR_FR_TOO_MANY_REDIRECTS | Request is redirected too many times; exceeds max redirects specified in axios configuration.
+| ERR_DEPRECATED | Deprecated feature or method used in axios. 
+| ERR_BAD_RESPONSE | Response cannot be parsed properly or is in an unexpected format. 
+| ERR_BAD_REQUEST | Requested has unexpected format or missing required parameters. |
+| ERR_CANCELED | Feature or method is canceled explicitly by the user.   
+| ERR_NOT_SUPPORT | Feature or method not supported in the current axios environment. 
+| ERR_INVALID_URL | Invalid URL provided for axios request.
+
+## Handling Errors
+
+the default behavior is to reject every response that returns with a status code that falls out of the range of 2xx and treat it as an error.
+
+```js
+axios.get('/user/12345')
+  .catch(function (error) {
+    if (error.response) {
+      // The request was made and the server responded with a status code
+      // that falls out of the range of 2xx
+      console.log(error.response.data);
+      console.log(error.response.status);
+      console.log(error.response.headers);
+    } else if (error.request) {
+      // The request was made but no response was received
+      // `error.request` is an instance of XMLHttpRequest in the browser and an instance of
+      // http.ClientRequest in node.js
+      console.log(error.request);
+    } else {
+      // Something happened in setting up the request that triggered an Error
+      console.log('Error', error.message);
+    }
+    console.log(error.config);
+  });
+```
+
+Using the `validateStatus` config option, you can override the default condition (status >= 200 && status < 300) and define HTTP code(s) that should throw an error.
+
+```js
+axios.get('/user/12345', {
+  validateStatus: function (status) {
+    return status < 500; // Resolve only if the status code is less than 500
+  }
+})
+```
+
+Using `toJSON` you get an object with more information about the HTTP error.
+
+```js
+axios.get('/user/12345')
+  .catch(function (error) {
+    console.log(error.toJSON());
+  });
+```
+
+## Cancellation
+
+### AbortController
+
+Starting from `v0.22.0` Axios supports AbortController to cancel requests in fetch API way:
+
+```js
+const controller = new AbortController();
+
+axios.get('/foo/bar', {
+   signal: controller.signal
+}).then(function(response) {
+   //...
+});
+// cancel the request
+controller.abort()
+```
+
+### CancelToken `👎deprecated`
+
+You can also cancel a request using a *CancelToken*.
+
+> The axios cancel token API is based on the withdrawn [cancellable promises proposal](https://github.com/tc39/proposal-cancelable-promises).
+
+> This API is deprecated since v0.22.0 and shouldn't be used in new projects
+
+You can create a cancel token using the `CancelToken.source` factory as shown below:
+
+```js
+const CancelToken = axios.CancelToken;
+const source = CancelToken.source();
+
+axios.get('/user/12345', {
+  cancelToken: source.token
+}).catch(function (thrown) {
+  if (axios.isCancel(thrown)) {
+    console.log('Request canceled', thrown.message);
+  } else {
+    // handle error
+  }
+});
+
+axios.post('/user/12345', {
+  name: 'new name'
+}, {
+  cancelToken: source.token
+})
+
+// cancel the request (the message parameter is optional)
+source.cancel('Operation canceled by the user.');
+```
+
+You can also create a cancel token by passing an executor function to the `CancelToken` constructor:
+
+```js
+const CancelToken = axios.CancelToken;
+let cancel;
+
+axios.get('/user/12345', {
+  cancelToken: new CancelToken(function executor(c) {
+    // An executor function receives a cancel function as a parameter
+    cancel = c;
+  })
+});
+
+// cancel the request
+cancel();
+```
+
+> **Note:** you can cancel several requests with the same cancel token/abort controller.
+> If a cancellation token is already cancelled at the moment of starting an Axios request, then the request is cancelled immediately, without any attempts to make a real request.
+
+> During the transition period, you can use both cancellation APIs, even for the same request:
+
+## Using `application/x-www-form-urlencoded` format
+
+### URLSearchParams
+
+By default, axios serializes JavaScript objects to `JSON`. To send data in the [`application/x-www-form-urlencoded` format](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST) instead, you can use the [`URLSearchParams`](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams) API, which is [supported](http://www.caniuse.com/#feat=urlsearchparams) in the vast majority of browsers,and [ Node](https://nodejs.org/api/url.html#url_class_urlsearchparams) starting with v10 (released in 2018).
+
+```js
+const params = new URLSearchParams({ foo: 'bar' });
+params.append('extraparam', 'value');
+axios.post('/foo', params);
+```
+
+### Query string (Older browsers)
+
+For compatibility with very old browsers, there is a [polyfill](https://github.com/WebReflection/url-search-params) available (make sure to polyfill the global environment).
+
+Alternatively, you can encode data using the [`qs`](https://github.com/ljharb/qs) library:
+
+```js
+const qs = require('qs');
+axios.post('/foo', qs.stringify({ 'bar': 123 }));
+```
+
+Or in another way (ES6),
+
+```js
+import qs from 'qs';
+const data = { 'bar': 123 };
+const options = {
+  method: 'POST',
+  headers: { 'content-type': 'application/x-www-form-urlencoded' },
+  data: qs.stringify(data),
+  url,
+};
+axios(options);
+```
+
+### Older Node.js versions
+
+For older Node.js engines, you can use the [`querystring`](https://nodejs.org/api/querystring.html) module as follows:
+
+```js
+const querystring = require('querystring');
+axios.post('https://something.com/', querystring.stringify({ foo: 'bar' }));
+```
+
+You can also use the [`qs`](https://github.com/ljharb/qs) library.
+
+> **Note**: The `qs` library is preferable if you need to stringify nested objects, as the `querystring` method has [known issues](https://github.com/nodejs/node-v0.x-archive/issues/1665) with that use case.
+
+### 🆕 Automatic serialization to URLSearchParams
+
+Axios will automatically serialize the data object to urlencoded format if the content-type header is set to "application/x-www-form-urlencoded".
+
+```js
+const data = {
+  x: 1,
+  arr: [1, 2, 3],
+  arr2: [1, [2], 3],
+  users: [{name: 'Peter', surname: 'Griffin'}, {name: 'Thomas', surname: 'Anderson'}],
+};
+
+await axios.postForm('https://postman-echo.com/post', data,
+  {headers: {'content-type': 'application/x-www-form-urlencoded'}}
+);
+```
+
+The server will handle it as:
+
+```js
+  {
+    x: '1',
+    'arr[]': [ '1', '2', '3' ],
+    'arr2[0]': '1',
+    'arr2[1][0]': '2',
+    'arr2[2]': '3',
+    'arr3[]': [ '1', '2', '3' ],
+    'users[0][name]': 'Peter',
+    'users[0][surname]': 'griffin',
+    'users[1][name]': 'Thomas',
+    'users[1][surname]': 'Anderson'
+  }
+````
+
+If your backend body-parser (like `body-parser` of `express.js`) supports nested objects decoding, you will get the same object on the server-side automatically
+
+```js
+  var app = express();
+
+  app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies
+
+  app.post('/', function (req, res, next) {
+     // echo body as JSON
+     res.send(JSON.stringify(req.body));
+  });
+
+  server = app.listen(3000);
+```
+
+## Using `multipart/form-data` format
+
+### FormData
+
+To send the data as a `multipart/formdata` you need to pass a formData instance as a payload.
+Setting the `Content-Type` header is not required as Axios guesses it based on the payload type.
+
+```js
+const formData = new FormData();
+formData.append('foo', 'bar');
+
+axios.post('https://httpbin.org/post', formData);
+```
+
+In node.js, you can use the [`form-data`](https://github.com/form-data/form-data) library as follows:
+
+```js
+const FormData = require('form-data');
+
+const form = new FormData();
+form.append('my_field', 'my value');
+form.append('my_buffer', new Buffer(10));
+form.append('my_file', fs.createReadStream('/foo/bar.jpg'));
+
+axios.post('https://example.com', form)
+```
+
+### 🆕 Automatic serialization to FormData
+
+Starting from `v0.27.0`, Axios supports automatic object serialization to a FormData object if the request `Content-Type`
+header is set to `multipart/form-data`.
+
+The following request will submit the data in a FormData format (Browser & Node.js):
+
+```js
+import axios from 'axios';
+
+axios.post('https://httpbin.org/post', {x: 1}, {
+  headers: {
+    'Content-Type': 'multipart/form-data'
+  }
+}).then(({data}) => console.log(data));
+```
+
+In the `node.js` build, the ([`form-data`](https://github.com/form-data/form-data)) polyfill is used by default.
+
+You can overload the FormData class by setting the `env.FormData` config variable,
+but you probably won't need it in most cases:
+
+```js
+const axios = require('axios');
+var FormData = require('form-data');
+
+axios.post('https://httpbin.org/post', {x: 1, buf: new Buffer(10)}, {
+  headers: {
+    'Content-Type': 'multipart/form-data'
+  }
+}).then(({data}) => console.log(data));
+```
+
+Axios FormData serializer supports some special endings to perform the following operations:
+
+- `{}` - serialize the value with JSON.stringify
+- `[]` - unwrap the array-like object as separate fields with the same key
+
+> **Note**: unwrap/expand operation will be used by default on arrays and FileList objects
+
+FormData serializer supports additional options via `config.formSerializer: object` property to handle rare cases:
+
+- `visitor: Function` - user-defined visitor function that will be called recursively to serialize the data object
+to a `FormData` object by following custom rules.
+
+- `dots: boolean = false` - use dot notation instead of brackets to serialize arrays and objects;
+
+- `metaTokens: boolean = true` - add the special ending (e.g `user{}: '{"name": "John"}'`) in the FormData key.
+The back-end body-parser could potentially use this meta-information to automatically parse the value as JSON.
+
+- `indexes: null|false|true = false` - controls how indexes will be added to unwrapped keys of `flat` array-like objects
+
+    - `null` - don't add brackets (`arr: 1`, `arr: 2`, `arr: 3`)
+    - `false`(default) - add empty brackets (`arr[]: 1`, `arr[]: 2`, `arr[]: 3`)
+    - `true` - add brackets with indexes  (`arr[0]: 1`, `arr[1]: 2`, `arr[2]: 3`)
+
+Let's say we have an object like this one:
+
+```js
+const obj = {
+  x: 1,
+  arr: [1, 2, 3],
+  arr2: [1, [2], 3],
+  users: [{name: 'Peter', surname: 'Griffin'}, {name: 'Thomas', surname: 'Anderson'}],
+  'obj2{}': [{x:1}]
+};
+```
+
+The following steps will be executed by the Axios serializer internally:
+
+```js
+const formData = new FormData();
+formData.append('x', '1');
+formData.append('arr[]', '1');
+formData.append('arr[]', '2');
+formData.append('arr[]', '3');
+formData.append('arr2[0]', '1');
+formData.append('arr2[1][0]', '2');
+formData.append('arr2[2]', '3');
+formData.append('users[0][name]', 'Peter');
+formData.append('users[0][surname]', 'Griffin');
+formData.append('users[1][name]', 'Thomas');
+formData.append('users[1][surname]', 'Anderson');
+formData.append('obj2{}', '[{"x":1}]');
+```
+
+Axios supports the following shortcut methods: `postForm`, `putForm`, `patchForm`
+which are just the corresponding http methods with the `Content-Type` header preset to `multipart/form-data`.
+
+## Files Posting
+
+You can easily submit a single file:
+
+```js
+await axios.postForm('https://httpbin.org/post', {
+  'myVar' : 'foo',
+  'file': document.querySelector('#fileInput').files[0]
+});
+```
+
+or multiple files as `multipart/form-data`:
+
+```js
+await axios.postForm('https://httpbin.org/post', {
+  'files[]': document.querySelector('#fileInput').files
+});
+```
+
+`FileList` object can be passed directly:
+
+```js
+await axios.postForm('https://httpbin.org/post', document.querySelector('#fileInput').files)
+```
+
+All files will be sent with the same field names: `files[]`.
+
+## 🆕 HTML Form Posting (browser)
+
+Pass HTML Form element as a payload to submit it as `multipart/form-data` content.
+
+```js
+await axios.postForm('https://httpbin.org/post', document.querySelector('#htmlForm'));
+```
+
+`FormData` and `HTMLForm` objects can also be posted as `JSON` by explicitly setting the `Content-Type` header to `application/json`:
+
+```js
+await axios.post('https://httpbin.org/post', document.querySelector('#htmlForm'), {
+  headers: {
+    'Content-Type': 'application/json'
+  }
+})
+```
+
+For example, the Form
+
+```html
+<form id="form">
+  <input type="text" name="foo" value="1">
+  <input type="text" name="deep.prop" value="2">
+  <input type="text" name="deep prop spaced" value="3">
+  <input type="text" name="baz" value="4">
+  <input type="text" name="baz" value="5">
+
+  <select name="user.age">
+    <option value="value1">Value 1</option>
+    <option value="value2" selected>Value 2</option>
+    <option value="value3">Value 3</option>
+  </select>
+
+  <input type="submit" value="Save">
+</form>
+```
+
+will be submitted as the following JSON object:
+
+```js
+{
+  "foo": "1",
+  "deep": {
+    "prop": {
+      "spaced": "3"
+    }
+  },
+  "baz": [
+    "4",
+    "5"
+  ],
+  "user": {
+    "age": "value2"
+  }
+}
+````
+
+Sending `Blobs`/`Files` as JSON (`base64`) is not currently supported.
+
+## 🆕 Progress capturing
+
+Axios supports both browser and node environments to capture request upload/download progress.
+
+```js    
+await axios.post(url, data, {
+  onUploadProgress: function (axiosProgressEvent) {
+    /*{
+      loaded: number;
+      total?: number;
+      progress?: number; // in range [0..1]
+      bytes: number; // how many bytes have been transferred since the last trigger (delta)
+      estimated?: number; // estimated time in seconds
+      rate?: number; // upload speed in bytes
+      upload: true; // upload sign
+    }*/
+  },
+
+  onDownloadProgress: function (axiosProgressEvent) {
+    /*{
+      loaded: number;
+      total?: number;
+      progress?: number;
+      bytes: number; 
+      estimated?: number;
+      rate?: number; // download speed in bytes
+      download: true; // download sign
+    }*/
+  }
+});  
+```
+
+You can also track stream upload/download progress in node.js:
+
+```js
+const {data} = await axios.post(SERVER_URL, readableStream, {
+   onUploadProgress: ({progress}) => {
+     console.log((progress * 100).toFixed(2));
+   },
+  
+   headers: {
+    'Content-Length': contentLength
+   },
+
+   maxRedirects: 0 // avoid buffering the entire stream
+});
+````
+
+> **Note:**
+> Capturing FormData upload progress is not currently supported in node.js environments.
+
+> **⚠️ Warning**
+> It is recommended to disable redirects by setting maxRedirects: 0 to upload the stream in the **node.js** environment,
+> as follow-redirects package will buffer the entire stream in RAM without following the "backpressure" algorithm.
+
+
+## 🆕 Rate limiting
+
+Download and upload rate limits can only be set for the http adapter (node.js):
+
+```js
+const {data} = await axios.post(LOCAL_SERVER_URL, myBuffer, {
+  onUploadProgress: ({progress, rate}) => {
+    console.log(`Upload [${(progress*100).toFixed(2)}%]: ${(rate / 1024).toFixed(2)}KB/s`)
+  },
+   
+  maxRate: [100 * 1024], // 100KB/s limit
+});
+```
+
+## 🆕 AxiosHeaders
+
+Axios has its own `AxiosHeaders` class to manipulate headers using a Map-like API that guarantees caseless work.
+Although HTTP is case-insensitive in headers, Axios will retain the case of the original header for stylistic reasons
+and for a workaround when servers mistakenly consider the header's case.
+The old approach of directly manipulating headers object is still available, but deprecated and not recommended for future usage.
+
+### Working with headers
+
+An AxiosHeaders object instance can contain different types of internal values. that control setting and merging logic.
+The final headers object with string values is obtained by Axios by calling the `toJSON` method.
+
+> Note: By JSON here we mean an object consisting only of string values intended to be sent over the network.
+
+The header value can be one of the following types:
+- `string` - normal string value that will be sent to the server
+- `null` - skip header when rendering to JSON
+- `false` - skip header when rendering to JSON, additionally indicates that `set` method must be called with `rewrite` option set to `true`
+  to overwrite this value (Axios uses this internally to allow users to opt out of installing certain headers like `User-Agent` or `Content-Type`)
+- `undefined` - value is not set
+
+> Note: The header value is considered set if it is not equal to undefined.
+
+The headers object is always initialized inside interceptors and transformers:
+
+```ts
+  axios.interceptors.request.use((request: InternalAxiosRequestConfig) => {
+      request.headers.set('My-header', 'value');
+
+      request.headers.set({
+        "My-set-header1": "my-set-value1",
+        "My-set-header2": "my-set-value2"
+      });
+      
+      request.headers.set('User-Agent', false); // disable subsequent setting the header by Axios
+
+      request.headers.setContentType('text/plain');
+    
+      request.headers['My-set-header2'] = 'newValue' // direct access is deprecated
+    
+      return request;
+    }
+  );
+````
+
+You can iterate over an `AxiosHeaders` instance using a `for...of` statement:
+
+````js
+const headers = new AxiosHeaders({
+  foo: '1',
+  bar: '2',
+  baz: '3'
+});
+
+for(const [header, value] of headers) {
+  console.log(header, value);
+}
+
+// foo 1
+// bar 2
+// baz 3
+````
+
+### new AxiosHeaders(headers?)
+
+Constructs a new `AxiosHeaders` instance. 
+
+```
+constructor(headers?: RawAxiosHeaders | AxiosHeaders | string);
+```
+
+If the headers object is a string, it will be parsed as RAW HTTP headers.
+
+````js
+const headers = new AxiosHeaders(`
+Host: www.bing.com
+User-Agent: curl/7.54.0
+Accept: */*`);
+
+console.log(headers);
+
+// Object [AxiosHeaders] {
+//   host: 'www.bing.com',
+//   'user-agent': 'curl/7.54.0',
+//   accept: '*/*'
+// }
+````
+
+### AxiosHeaders#set
+
+```ts
+set(headerName, value: Axios, rewrite?: boolean);
+set(headerName, value, rewrite?: (this: AxiosHeaders, value: string, name: string, headers: RawAxiosHeaders) => boolean);
+set(headers?: RawAxiosHeaders | AxiosHeaders | string, rewrite?: boolean);
+```
+
+The `rewrite` argument controls the overwriting behavior:
+- `false` - do not overwrite if header's value is set (is not `undefined`)
+- `undefined` (default) - overwrite the header unless its value is set to `false`
+- `true` - rewrite anyway
+
+The option can also accept a user-defined function that determines whether the value should be overwritten or not.
+
+Returns `this`.
+
+### AxiosHeaders#get(header)
+
+```
+  get(headerName: string, matcher?: true | AxiosHeaderMatcher): AxiosHeaderValue;
+  get(headerName: string, parser: RegExp): RegExpExecArray | null;
+````
+
+Returns the internal value of the header. It can take an extra argument to parse the header's value with `RegExp.exec`,
+matcher function or internal key-value parser.
+
+```ts
+const headers = new AxiosHeaders({
+  'Content-Type': 'multipart/form-data; boundary=Asrf456BGe4h'
+});
+
+console.log(headers.get('Content-Type')); 
+// multipart/form-data; boundary=Asrf456BGe4h
+
+console.log(headers.get('Content-Type', true)); // parse key-value pairs from a string separated with \s,;= delimiters:
+// [Object: null prototype] {
+//   'multipart/form-data': undefined,
+//    boundary: 'Asrf456BGe4h'
+// }
+
+
+console.log(headers.get('Content-Type', (value, name, headers) => {
+  return String(value).replace(/a/g, 'ZZZ');
+}));
+// multipZZZrt/form-dZZZtZZZ; boundZZZry=Asrf456BGe4h
+
+console.log(headers.get('Content-Type', /boundary=(\w+)/)?.[0]);
+// boundary=Asrf456BGe4h
+
+```
+
+Returns the value of the header.
+
+### AxiosHeaders#has(header, matcher?)
+
+```
+has(header: string, matcher?: AxiosHeaderMatcher): boolean;
+```
+
+Returns `true` if the header is set (has no `undefined` value).
+
+### AxiosHeaders#delete(header, matcher?)
+
+```
+delete(header: string | string[], matcher?: AxiosHeaderMatcher): boolean;
+```
+
+Returns `true` if at least one header has been removed.
+
+### AxiosHeaders#clear(matcher?)
+
+```
+clear(matcher?: AxiosHeaderMatcher): boolean;
+```
+
+Removes all headers. 
+Unlike the `delete` method matcher, this optional matcher will be used to match against the header name rather than the value.
+
+```ts
+const headers = new AxiosHeaders({
+  'foo': '1',
+  'x-foo': '2',
+  'x-bar': '3',
+});
+
+console.log(headers.clear(/^x-/)); // true
+
+console.log(headers.toJSON()); // [Object: null prototype] { foo: '1' }
+```
+
+Returns `true` if at least one header has been cleared.
+
+### AxiosHeaders#normalize(format);
+
+If the headers object was changed directly, it can have duplicates with the same name but in different cases.
+This method normalizes the headers object by combining duplicate keys into one.
+Axios uses this method internally after calling each interceptor.
+Set `format` to true for converting headers name to lowercase and capitalize the initial letters (`cOntEnt-type` => `Content-Type`)
+
+```js
+const headers = new AxiosHeaders({
+  'foo': '1',
+});
+
+headers.Foo = '2';
+headers.FOO = '3';
+
+console.log(headers.toJSON()); // [Object: null prototype] { foo: '1', Foo: '2', FOO: '3' }
+console.log(headers.normalize().toJSON()); // [Object: null prototype] { foo: '3' }
+console.log(headers.normalize(true).toJSON()); // [Object: null prototype] { Foo: '3' }
+```
+
+Returns `this`.
+
+### AxiosHeaders#concat(...targets)
+
+```
+concat(...targets: Array<AxiosHeaders | RawAxiosHeaders | string | undefined | null>): AxiosHeaders;
+```
+
+Merges the instance with targets into a new `AxiosHeaders` instance. If the target is a string, it will be parsed as RAW HTTP headers.
+
+Returns a new `AxiosHeaders` instance.
+
+### AxiosHeaders#toJSON(asStrings?)
+
+````
+toJSON(asStrings?: boolean): RawAxiosHeaders;
+````
+
+Resolve all internal headers values into a new null prototype object. 
+Set `asStrings` to true to resolve arrays as a string containing all elements, separated by commas.
+
+### AxiosHeaders.from(thing?)
+
+````
+from(thing?: AxiosHeaders | RawAxiosHeaders | string): AxiosHeaders;
+````
+
+Returns a new `AxiosHeaders` instance created from the raw headers passed in,
+or simply returns the given headers object if it's an `AxiosHeaders` instance.
+
+### AxiosHeaders.concat(...targets)
+
+````
+concat(...targets: Array<AxiosHeaders | RawAxiosHeaders | string | undefined | null>): AxiosHeaders;
+````
+
+Returns a new `AxiosHeaders` instance created by merging the target objects.
+
+### Shortcuts
+
+The following shortcuts are available:
+
+- `setContentType`, `getContentType`, `hasContentType`
+
+- `setContentLength`, `getContentLength`, `hasContentLength`
+
+- `setAccept`, `getAccept`, `hasAccept`
+
+- `setUserAgent`, `getUserAgent`, `hasUserAgent`
+
+- `setContentEncoding`, `getContentEncoding`, `hasContentEncoding`
+
+
+## Semver
+
+Until axios reaches a `1.0` release, breaking changes will be released with a new minor version. For example `0.5.1`, and `0.5.4` will have the same API, but `0.6.0` will have breaking changes.
+
+## Promises
+
+axios depends on a native ES6 Promise implementation to be [supported](https://caniuse.com/promises).
+If your environment doesn't support ES6 Promises, you can [polyfill](https://github.com/jakearchibald/es6-promise).
+
+## TypeScript
+
+axios includes [TypeScript](https://typescriptlang.org) definitions and a type guard for axios errors.
+
+```typescript
+let user: User = null;
+try {
+  const { data } = await axios.get('/user?ID=12345');
+  user = data.userDetails;
+} catch (error) {
+  if (axios.isAxiosError(error)) {
+    handleAxiosError(error);
+  } else {
+    handleUnexpectedError(error);
+  }
+}
+```
+
+Because axios dual publishes with an ESM default export and a CJS `module.exports`, there are some caveats.
+The recommended setting is to use `"moduleResolution": "node16"` (this is implied by `"module": "node16"`). Note that this requires TypeScript 4.7 or greater.
+If use ESM, your settings should be fine.
+If you compile TypeScript to CJS and you can’t use `"moduleResolution": "node 16"`, you have to enable `esModuleInterop`.
+If you use TypeScript to type check CJS JavaScript code, your only option is to use `"moduleResolution": "node16"`.

+# axios // adapters
+
+The modules under `adapters/` are modules that handle dispatching a request and settling a returned `Promise` once a response is received.
+
+## Example
+
+```js
+var settle = require('./../core/settle');
+
+module.exports = function myAdapter(config) {
+  // At this point:
+  //  - config has been merged with defaults
+  //  - request transformers have already run
+  //  - request interceptors have already run
+  
+  // Make the request using config provided
+  // Upon response settle the Promise
+
+  return new Promise(function(resolve, reject) {
+  
+    var response = {
+      data: responseData,
+      status: request.status,
+      statusText: request.statusText,
+      headers: responseHeaders,
+      config: config,
+      request: request
+    };
+
+    settle(resolve, reject, response);
+
+    // From here:
+    //  - response transformers will run
+    //  - response interceptors will run
+  });
+}

+
+The modules found in `core/` should be modules that are specific to the domain logic of axios. These modules would most likely not make sense to be consumed outside of the axios module, as their logic is too specific. Some examples of core modules are:
+
+- Dispatching requests
+  - Requests sent via `adapters/` (see lib/adapters/README.md)
+- Managing interceptors
+- Handling config

+# combined-stream
+
+A stream that emits multiple other streams one after another.
+
+**NB** Currently `combined-stream` works with streams version 1 only. There is ongoing effort to switch this library to streams version 2. Any help is welcome. :) Meanwhile you can explore other libraries that provide streams2 support with more or less compatibility with `combined-stream`.
+
+- [combined-stream2](https://www.npmjs.com/package/combined-stream2): A drop-in streams2-compatible replacement for the combined-stream module.
+
+- [multistream](https://www.npmjs.com/package/multistream): A stream that emits multiple other streams one after another.
+
+## Installation
+
+``` bash
+npm install combined-stream
+```
+
+## Usage
+
+Here is a simple example that shows how you can use combined-stream to combine
+two files into one:
+
+``` javascript
+var CombinedStream = require('combined-stream');
+var fs = require('fs');
+
+var combinedStream = CombinedStream.create();
+combinedStream.append(fs.createReadStream('file1.txt'));
+combinedStream.append(fs.createReadStream('file2.txt'));
+
+combinedStream.pipe(fs.createWriteStream('combined.txt'));
+```
+
+While the example above works great, it will pause all source streams until
+they are needed. If you don't want that to happen, you can set `pauseStreams`
+to `false`:
+
+``` javascript
+var CombinedStream = require('combined-stream');
+var fs = require('fs');
+
+var combinedStream = CombinedStream.create({pauseStreams: false});
+combinedStream.append(fs.createReadStream('file1.txt'));
+combinedStream.append(fs.createReadStream('file2.txt'));
+
+combinedStream.pipe(fs.createWriteStream('combined.txt'));
+```
+
+However, what if you don't have all the source streams yet, or you don't want
+to allocate the resources (file descriptors, memory, etc.) for them right away?
+Well, in that case you can simply provide a callback that supplies the stream
+by calling a `next()` function:
+
+``` javascript
+var CombinedStream = require('combined-stream');
+var fs = require('fs');
+
+var combinedStream = CombinedStream.create();
+combinedStream.append(function(next) {
+  next(fs.createReadStream('file1.txt'));
+});
+combinedStream.append(function(next) {
+  next(fs.createReadStream('file2.txt'));
+});
+
+combinedStream.pipe(fs.createWriteStream('combined.txt'));
+```
+
+## API
+
+### CombinedStream.create([options])
+
+Returns a new combined stream object. Available options are:
+
+* `maxDataSize`
+* `pauseStreams`
+
+The effect of those options is described below.
+
+### combinedStream.pauseStreams = `true`
+
+Whether to apply back pressure to the underlaying streams. If set to `false`,
+the underlaying streams will never be paused. If set to `true`, the
+underlaying streams will be paused right after being appended, as well as when
+`delayedStream.pipe()` wants to throttle.
+
+### combinedStream.maxDataSize = `2 * 1024 * 1024`
+
+The maximum amount of bytes (or characters) to buffer for all source streams.
+If this value is exceeded, `combinedStream` emits an `'error'` event.
+
+### combinedStream.dataSize = `0`
+
+The amount of bytes (or characters) currently buffered by `combinedStream`.
+
+### combinedStream.append(stream)
+
+Appends the given `stream` to the combinedStream object. If `pauseStreams` is
+set to `true, this stream will also be paused right away.
+
+`streams` can also be a function that takes one parameter called `next`. `next`
+is a function that must be invoked in order to provide the `next` stream, see
+example above.
+
+Regardless of how the `stream` is appended, combined-stream always attaches an
+`'error'` listener to it, so you don't have to do that manually.
+
+Special case: `stream` can also be a String or Buffer.
+
+### combinedStream.write(data)
+
+You should not call this, `combinedStream` takes care of piping the appended
+streams into itself for you.
+
+### combinedStream.resume()
+
+Causes `combinedStream` to start drain the streams it manages. The function is
+idempotent, and also emits a `'resume'` event each time which usually goes to
+the stream that is currently being drained.
+
+### combinedStream.pause();
+
+If `combinedStream.pauseStreams` is set to `false`, this does nothing.
+Otherwise a `'pause'` event is emitted, this goes to the stream that is
+currently being drained, so you can use it to apply back pressure.
+
+### combinedStream.end();
+
+Sets `combinedStream.writable` to false, emits an `'end'` event, and removes
+all streams from the queue.
+
+### combinedStream.destroy();
+
+Same as `combinedStream.end()`, except it emits a `'close'` event instead of
+`'end'`.

+# delayed-stream
+
+Buffers events from a stream until you are ready to handle them.
+
+## Installation
+
+``` bash
+npm install delayed-stream
+```
+
+## Usage
+
+The following example shows how to write a http echo server that delays its
+response by 1000 ms.
+
+``` javascript
+var DelayedStream = require('delayed-stream');
+var http = require('http');
+
+http.createServer(function(req, res) {
+  var delayed = DelayedStream.create(req);
+
+  setTimeout(function() {
+    res.writeHead(200);
+    delayed.pipe(res);
+  }, 1000);
+});
+```
+
+If you are not using `Stream#pipe`, you can also manually release the buffered
+events by calling `delayedStream.resume()`:
+
+``` javascript
+var delayed = DelayedStream.create(req);
+
+setTimeout(function() {
+  // Emit all buffered events and resume underlaying source
+  delayed.resume();
+}, 1000);
+```
+
+## Implementation
+
+In order to use this meta stream properly, here are a few things you should
+know about the implementation.
+
+### Event Buffering / Proxying
+
+All events of the `source` stream are hijacked by overwriting the `source.emit`
+method. Until node implements a catch-all event listener, this is the only way.
+
+However, delayed-stream still continues to emit all events it captures on the
+`source`, regardless of whether you have released the delayed stream yet or
+not.
+
+Upon creation, delayed-stream captures all `source` events and stores them in
+an internal event buffer. Once `delayedStream.release()` is called, all
+buffered events are emitted on the `delayedStream`, and the event buffer is
+cleared. After that, delayed-stream merely acts as a proxy for the underlaying
+source.
+
+### Error handling
+
+Error events on `source` are buffered / proxied just like any other events.
+However, `delayedStream.create` attaches a no-op `'error'` listener to the
+`source`. This way you only have to handle errors on the `delayedStream`
+object, rather than in two places.
+
+### Buffer limits
+
+delayed-stream provides a `maxDataSize` property that can be used to limit
+the amount of data being buffered. In order to protect you from bad `source`
+streams that don't react to `source.pause()`, this feature is enabled by
+default.
+
+## API
+
+### DelayedStream.create(source, [options])
+
+Returns a new `delayedStream`. Available options are:
+
+* `pauseStream`
+* `maxDataSize`
+
+The description for those properties can be found below.
+
+### delayedStream.source
+
+The `source` stream managed by this object. This is useful if you are
+passing your `delayedStream` around, and you still want to access properties
+on the `source` object.
+
+### delayedStream.pauseStream = true
+
+Whether to pause the underlaying `source` when calling
+`DelayedStream.create()`. Modifying this property afterwards has no effect.
+
+### delayedStream.maxDataSize = 1024 * 1024
+
+The amount of data to buffer before emitting an `error`.
+
+If the underlaying source is emitting `Buffer` objects, the `maxDataSize`
+refers to bytes.
+
+If the underlaying source is emitting JavaScript strings, the size refers to
+characters.
+
+If you know what you are doing, you can set this property to `Infinity` to
+disable this feature. You can also modify this property during runtime.
+
+### delayedStream.dataSize = 0
+
+The amount of data buffered so far.
+
+### delayedStream.readable
+
+An ECMA5 getter that returns the value of `source.readable`.
+
+### delayedStream.resume()
+
+If the `delayedStream` has not been released so far, `delayedStream.release()`
+is called.
+
+In either case, `source.resume()` is called.
+
+### delayedStream.pause()
+
+Calls `source.pause()`.
+
+### delayedStream.pipe(dest)
+
+Calls `delayedStream.resume()` and then proxies the arguments to `source.pipe`.
+
+### delayedStream.release()
+
+Emits and clears all events that have been buffered up so far. This does not
+resume the underlaying source, use `delayedStream.resume()` instead.

+## Follow Redirects
+
+Drop-in replacement for Node's `http` and `https` modules that automatically follows redirects.
+
+[![npm version](https://img.shields.io/npm/v/follow-redirects.svg)](https://www.npmjs.com/package/follow-redirects)
+[![Build Status](https://github.com/follow-redirects/follow-redirects/workflows/CI/badge.svg)](https://github.com/follow-redirects/follow-redirects/actions)
+[![Coverage Status](https://coveralls.io/repos/follow-redirects/follow-redirects/badge.svg?branch=master)](https://coveralls.io/r/follow-redirects/follow-redirects?branch=master)
+[![npm downloads](https://img.shields.io/npm/dm/follow-redirects.svg)](https://www.npmjs.com/package/follow-redirects)
+[![Sponsor on GitHub](https://img.shields.io/static/v1?label=Sponsor&message=%F0%9F%92%96&logo=GitHub)](https://github.com/sponsors/RubenVerborgh)
+
+`follow-redirects` provides [request](https://nodejs.org/api/http.html#http_http_request_options_callback) and [get](https://nodejs.org/api/http.html#http_http_get_options_callback)
+ methods that behave identically to those found on the native [http](https://nodejs.org/api/http.html#http_http_request_options_callback) and [https](https://nodejs.org/api/https.html#https_https_request_options_callback)
+ modules, with the exception that they will seamlessly follow redirects.
+
+```javascript
+const { http, https } = require('follow-redirects');
+
+http.get('http://bit.ly/900913', response => {
+  response.on('data', chunk => {
+    console.log(chunk);
+  });
+}).on('error', err => {
+  console.error(err);
+});
+```
+
+You can inspect the final redirected URL through the `responseUrl` property on the `response`.
+If no redirection happened, `responseUrl` is the original request URL.
+
+```javascript
+const request = https.request({
+  host: 'bitly.com',
+  path: '/UHfDGO',
+}, response => {
+  console.log(response.responseUrl);
+  // 'http://duckduckgo.com/robots.txt'
+});
+request.end();
+```
+
+## Options
+### Global options
+Global options are set directly on the `follow-redirects` module:
+
+```javascript
+const followRedirects = require('follow-redirects');
+followRedirects.maxRedirects = 10;
+followRedirects.maxBodyLength = 20 * 1024 * 1024; // 20 MB
+```
+
+The following global options are supported:
+
+- `maxRedirects` (default: `21`) – sets the maximum number of allowed redirects; if exceeded, an error will be emitted.
+
+- `maxBodyLength` (default: 10MB) – sets the maximum size of the request body; if exceeded, an error will be emitted.
+
+### Per-request options
+Per-request options are set by passing an `options` object:
+
+```javascript
+const url = require('url');
+const { http, https } = require('follow-redirects');
+
+const options = url.parse('http://bit.ly/900913');
+options.maxRedirects = 10;
+options.beforeRedirect = (options, response, request) => {
+  // Use this to adjust the request options upon redirecting,
+  // to inspect the latest response headers,
+  // or to cancel the request by throwing an error
+
+  // response.headers = the redirect response headers
+  // response.statusCode = the redirect response code (eg. 301, 307, etc.)
+
+  // request.url = the requested URL that resulted in a redirect
+  // request.headers = the headers in the request that resulted in a redirect
+  // request.method = the method of the request that resulted in a redirect
+  if (options.hostname === "example.com") {
+    options.auth = "user:password";
+  }
+};
+http.request(options);
+```
+
+In addition to the [standard HTTP](https://nodejs.org/api/http.html#http_http_request_options_callback) and [HTTPS options](https://nodejs.org/api/https.html#https_https_request_options_callback),
+the following per-request options are supported:
+- `followRedirects` (default: `true`) – whether redirects should be followed.
+
+- `maxRedirects` (default: `21`) – sets the maximum number of allowed redirects; if exceeded, an error will be emitted.
+
+- `maxBodyLength` (default: 10MB) – sets the maximum size of the request body; if exceeded, an error will be emitted.
+
+- `beforeRedirect` (default: `undefined`) – optionally change the request `options` on redirects, or abort the request by throwing an error.
+
+- `agents` (default: `undefined`) – sets the `agent` option per protocol, since HTTP and HTTPS use different agents. Example value: `{ http: new http.Agent(), https: new https.Agent() }`
+
+- `trackRedirects` (default: `false`) – whether to store the redirected response details into the `redirects` array on the response object.
+
+
+### Advanced usage
+By default, `follow-redirects` will use the Node.js default implementations
+of [`http`](https://nodejs.org/api/http.html)
+and [`https`](https://nodejs.org/api/https.html).
+To enable features such as caching and/or intermediate request tracking,
+you might instead want to wrap `follow-redirects` around custom protocol implementations:
+
+```javascript
+const { http, https } = require('follow-redirects').wrap({
+  http: require('your-custom-http'),
+  https: require('your-custom-https'),
+});
+```
+
+Such custom protocols only need an implementation of the `request` method.
+
+## Browser Usage
+
+Due to the way the browser works,
+the `http` and `https` browser equivalents perform redirects by default.
+
+By requiring `follow-redirects` this way:
+```javascript
+const http = require('follow-redirects/http');
+const https = require('follow-redirects/https');
+```
+you can easily tell webpack and friends to replace
+`follow-redirect` by the built-in versions:
+
+```json
+{
+  "follow-redirects/http"  : "http",
+  "follow-redirects/https" : "https"
+}
+```
+
+## Contributing
+
+Pull Requests are always welcome. Please [file an issue](https://github.com/follow-redirects/follow-redirects/issues)
+ detailing your proposal before you invest your valuable time. Additional features and bug fixes should be accompanied
+ by tests. You can run the test suite locally with a simple `npm test` command.
+
+## Debug Logging
+
+`follow-redirects` uses the excellent [debug](https://www.npmjs.com/package/debug) for logging. To turn on logging
+ set the environment variable `DEBUG=follow-redirects` for debug output from just this module. When running the test
+ suite it is sometimes advantageous to set `DEBUG=*` to see output from the express server as well.

+
+A library to create readable ```"multipart/form-data"``` streams. Can be used to submit forms and file uploads to other web applications.
+
+The API of this library is inspired by the [XMLHttpRequest-2 FormData Interface][xhr2-fd].

+
+## Install
+
+```
+npm install --save form-data
+```
+
+## Usage
+
+In this example we are constructing a form with 3 fields that contain a string,
+a buffer and a file stream.
+
+``` javascript
+var FormData = require('form-data');
+var fs = require('fs');
+
+var form = new FormData();
+form.append('my_field', 'my value');
+form.append('my_buffer', new Buffer(10));
+form.append('my_file', fs.createReadStream('/foo/bar.jpg'));
+```
+
+Also you can use http-response stream:
+
+``` javascript
+var FormData = require('form-data');
+var http = require('http');
+
+var form = new FormData();
+
+http.request('http://nodejs.org/images/logo.png', function(response) {
+  form.append('my_field', 'my value');
+  form.append('my_buffer', new Buffer(10));
+  form.append('my_logo', response);
+});
+```
+
+Or @mikeal's [request](https://github.com/request/request) stream:
+
+``` javascript
+var FormData = require('form-data');
+var request = require('request');
+
+var form = new FormData();
+
+form.append('my_field', 'my value');
+form.append('my_buffer', new Buffer(10));
+form.append('my_logo', request('http://nodejs.org/images/logo.png'));
+```
+
+In order to submit this form to a web application, call ```submit(url, [callback])``` method:
+
+``` javascript
+form.submit('http://example.org/', function(err, res) {
+  // res – response object (http.IncomingMessage)  //
+  res.resume();
+});
+
+```
+
+For more advanced request manipulations ```submit()``` method returns ```http.ClientRequest``` object, or you can choose from one of the alternative submission methods.
+
+### Custom options
+
+You can provide custom options, such as `maxDataSize`:
+
+``` javascript
+var FormData = require('form-data');
+
+var form = new FormData({ maxDataSize: 20971520 });
+form.append('my_field', 'my value');
+form.append('my_buffer', /* something big */);
+```
+
+List of available options could be found in [combined-stream](https://github.com/felixge/node-combined-stream/blob/master/lib/combined_stream.js#L7-L15)
+
+### Alternative submission methods
+
+You can use node's http client interface:
+
+``` javascript
+var http = require('http');
+
+var request = http.request({
+  method: 'post',
+  host: 'example.org',
+  path: '/upload',
+  headers: form.getHeaders()
+});
+
+form.pipe(request);
+
+request.on('response', function(res) {
+  console.log(res.statusCode);
+});
+```
+
+Or if you would prefer the `'Content-Length'` header to be set for you:
+
+``` javascript
+form.submit('example.org/upload', function(err, res) {
+  console.log(res.statusCode);
+});
+```
+
+To use custom headers and pre-known length in parts:
+
+``` javascript
+var CRLF = '\r\n';
+var form = new FormData();
+
+var options = {
+  header: CRLF + '--' + form.getBoundary() + CRLF + 'X-Custom-Header: 123' + CRLF + CRLF,
+  knownLength: 1
+};
+
+form.append('my_buffer', buffer, options);
+
+form.submit('http://example.com/', function(err, res) {
+  if (err) throw err;
+  console.log('Done');
+});
+```
+
+Form-Data can recognize and fetch all the required information from common types of streams (```fs.readStream```, ```http.response``` and ```mikeal's request```), for some other types of streams you'd need to provide "file"-related information manually:
+
+``` javascript
+someModule.stream(function(err, stdout, stderr) {
+  if (err) throw err;
+
+  var form = new FormData();
+
+  form.append('file', stdout, {
+    filename: 'unicycle.jpg', // ... or:
+    filepath: 'photos/toys/unicycle.jpg',
+    contentType: 'image/jpeg',
+    knownLength: 19806
+  });
+
+  form.submit('http://example.com/', function(err, res) {
+    if (err) throw err;
+    console.log('Done');
+  });
+});
+```
+
+The `filepath` property overrides `filename` and may contain a relative path. This is typically used when uploading [multiple files from a directory](https://wicg.github.io/entries-api/#dom-htmlinputelement-webkitdirectory).
+
+For edge cases, like POST request to URL with query string or to pass HTTP auth credentials, object can be passed to `form.submit()` as first parameter:
+
+``` javascript
+form.submit({
+  host: 'example.com',
+  path: '/probably.php?extra=params',
+  auth: 'username:password'
+}, function(err, res) {
+  console.log(res.statusCode);
+});
+```
+
+In case you need to also send custom HTTP headers with the POST request, you can use the `headers` key in first parameter of `form.submit()`:
+
+``` javascript
+form.submit({
+  host: 'example.com',
+  path: '/surelynot.php',
+  headers: {'x-test-header': 'test-header-value'}
+}, function(err, res) {
+  console.log(res.statusCode);
+});
+```

+- [_String_ toString()](https://github.com/form-data/form-data#string-tostring)
+
+#### _Void_ append( **String** _field_, **Mixed** _value_ [, **Mixed** _options_] )
+Append data to the form. You can submit about any format (string, integer, boolean, buffer, etc.). However, Arrays are not supported and need to be turned into strings by the user.
+```javascript
+var form = new FormData();
+form.append( 'my_string', 'my value' );
+form.append( 'my_integer', 1 );
+form.append( 'my_boolean', true );
+form.append( 'my_buffer', new Buffer(10) );
+form.append( 'my_array_as_json', JSON.stringify( ['bird','cute'] ) )
+```
+
+You may provide a string for options, or an object.
+```javascript
+// Set filename by providing a string for options
+form.append( 'my_file', fs.createReadStream('/foo/bar.jpg'), 'bar.jpg' );
+
+// provide an object.
+form.append( 'my_file', fs.createReadStream('/foo/bar.jpg'), {filename: 'bar.jpg', contentType: 'image/jpeg', knownLength: 19806} );
+```
+
+#### _Headers_ getHeaders( [**Headers** _userHeaders_] )
+This method adds the correct `content-type` header to the provided array of `userHeaders`.
+
+#### _String_ getBoundary()
+Return the boundary of the formData. By default, the boundary consists of 26 `-` followed by 24 numbers
+for example:
+```javascript
+--------------------------515890814546601021194782
+```
+
+#### _Void_ setBoundary(String _boundary_)
+Set the boundary string, overriding the default behavior described above.
+
+_Note: The boundary must be unique and may not appear in the data._
+
+#### _Buffer_ getBuffer()
+Return the full formdata request package, as a Buffer. You can insert this Buffer in e.g. Axios to send multipart data.
+```javascript
+var form = new FormData();
+form.append( 'my_buffer', Buffer.from([0x4a,0x42,0x20,0x52,0x6f,0x63,0x6b,0x73]) );
+form.append( 'my_file', fs.readFileSync('/foo/bar.jpg') );
+
+axios.post( 'https://example.com/path/to/api',
+            form.getBuffer(),
+            form.getHeaders()
+          )
+```
+**Note:** Because the output is of type Buffer, you can only append types that are accepted by Buffer: *string, Buffer, ArrayBuffer, Array, or Array-like Object*. A ReadStream for example will result in an error.
+
+#### _Integer_ getLengthSync()
+Same as `getLength` but synchronous.
+
+_Note: getLengthSync __doesn't__ calculate streams length._
+
+#### _Integer_ getLength( **function** _callback_ )
+Returns the `Content-Length` async. The callback is used to handle errors and continue once the length has been calculated
+```javascript
+this.getLength(function(err, length) {
+  if (err) {
+    this._error(err);
+    return;
+  }
+
+  // add content length
+  request.setHeader('Content-Length', length);
+
+  ...
+}.bind(this));
+```
+
+#### _Boolean_ hasKnownLength()
+Checks if the length of added values is known.
+
+#### _Request_ submit( _params_, **function** _callback_ )
+Submit the form to a web application.
+```javascript
+var form = new FormData();
+form.append( 'my_string', 'Hello World' );
+
+form.submit( 'http://example.com/', function(err, res) {
+  // res – response object (http.IncomingMessage)  //
+  res.resume();
+} );
+```
+
+#### _String_ toString()
+Returns the form data as a string. Don't use this if you are sending files or buffers, use `getBuffer()` instead.
+
+### Integration with other libraries
+
+#### Request
+
+Form submission using  [request](https://github.com/request/request):
+
+```javascript
+var formData = {
+  my_field: 'my_value',
+  my_file: fs.createReadStream(__dirname + '/unicycle.jpg'),
+};
+
+request.post({url:'http://service.com/upload', formData: formData}, function(err, httpResponse, body) {
+  if (err) {
+    return console.error('upload failed:', err);
+  }
+  console.log('Upload successful!  Server responded with:', body);
+});
+```
+
+For more details see [request readme](https://github.com/request/request#multipartform-data-multipart-form-uploads).
+
+#### node-fetch
+
+You can also submit a form using [node-fetch](https://github.com/bitinn/node-fetch):
+
+```javascript
+var form = new FormData();
+
+form.append('a', 1);
+
+fetch('http://example.com', { method: 'POST', body: form })
+    .then(function(res) {
+        return res.json();
+    }).then(function(json) {
+        console.log(json);
+    });
+```
+
+#### axios
+
+In Node.js you can post a file using [axios](https://github.com/axios/axios):
+```javascript
+const form = new FormData();
+const stream = fs.createReadStream(PATH_TO_FILE);
+
+form.append('image', stream);
+
+// In Node.js environment you need to set boundary in the header field 'Content-Type' by calling method `getHeaders`
+const formHeaders = form.getHeaders();
+
+axios.post('http://example.com', form, {
+  headers: {
+    ...formHeaders,
+  },
+})
+.then(response => response)
+.catch(error => error)
+```
+
+## Notes
+
+- ```getLengthSync()``` method DOESN'T calculate length for streams, use ```knownLength``` options as workaround.
+- ```getLength(cb)``` will send an error as first parameter of callback if stream length cannot be calculated (e.g. send in custom streams w/o using ```knownLength```).
+- ```submit``` will not add `content-length` if form length is unknown or not calculable.
+- Starting version `2.x` FormData has dropped support for `node@0.10.x`.
+- Starting version `3.x` FormData has dropped support for `node@4.x`.

+**Note:** Because the output is of type Buffer, you can only append types that are accepted by Buffer: *string, Buffer, ArrayBuffer, Array, or Array-like Object*. A ReadStream for example will result in an error.
+
+#### _Integer_ getLengthSync()
+Same as `getLength` but synchronous.
+
+_Note: getLengthSync __doesn't__ calculate streams length._
+
+#### _Integer_ getLength( **function** _callback_ )
+Returns the `Content-Length` async. The callback is used to handle errors and continue once the length has been calculated
+```javascript
+this.getLength(function(err, length) {
+  if (err) {
+    this._error(err);
+    return;
+  }
+
+  // add content length
+  request.setHeader('Content-Length', length);
+
+  ...
+}.bind(this));
+```
+
+#### _Boolean_ hasKnownLength()
+Checks if the length of added values is known.
+
+#### _Request_ submit( _params_, **function** _callback_ )
+Submit the form to a web application.
+```javascript
+var form = new FormData();
+form.append( 'my_string', 'Hello World' );
+
+form.submit( 'http://example.com/', function(err, res) {
+  // res – response object (http.IncomingMessage)  //
+  res.resume();
+} );
+```
+
+#### _String_ toString()
+Returns the form data as a string. Don't use this if you are sending files or buffers, use `getBuffer()` instead.
+
+### Integration with other libraries
+
+#### Request
+
+Form submission using  [request](https://github.com/request/request):
+
+```javascript
+var formData = {
+  my_field: 'my_value',
+  my_file: fs.createReadStream(__dirname + '/unicycle.jpg'),
+};
+
+request.post({url:'http://service.com/upload', formData: formData}, function(err, httpResponse, body) {
+  if (err) {
+    return console.error('upload failed:', err);
+  }
+  console.log('Upload successful!  Server responded with:', body);
+});
+```
+
+For more details see [request readme](https://github.com/request/request#multipartform-data-multipart-form-uploads).
+
+#### node-fetch
+
+You can also submit a form using [node-fetch](https://github.com/bitinn/node-fetch):
+
+```javascript
+var form = new FormData();
+
+form.append('a', 1);
+
+fetch('http://example.com', { method: 'POST', body: form })
+    .then(function(res) {
+        return res.json();
+    }).then(function(json) {
+        console.log(json);
+    });
+```
+
+#### axios
+
+In Node.js you can post a file using [axios](https://github.com/axios/axios):
+```javascript
+const form = new FormData();
+const stream = fs.createReadStream(PATH_TO_FILE);
+
+form.append('image', stream);
+
+// In Node.js environment you need to set boundary in the header field 'Content-Type' by calling method `getHeaders`
+const formHeaders = form.getHeaders();
+
+axios.post('http://example.com', form, {
+  headers: {
+    ...formHeaders,
+  },
+})
+.then(response => response)
+.catch(error => error)
+```
+
+## Notes
+
+- ```getLengthSync()``` method DOESN'T calculate length for streams, use ```knownLength``` options as workaround.
+- ```getLength(cb)``` will send an error as first parameter of callback if stream length cannot be calculated (e.g. send in custom streams w/o using ```knownLength```).
+- ```submit``` will not add `content-length` if form length is unknown or not calculable.
+- Starting version `2.x` FormData has dropped support for `node@0.10.x`.
+- Starting version `3.x` FormData has dropped support for `node@4.x`.

+## Introduction
+
+In many modern web applications, WebSockets are used to implement realtime, live-updating user interfaces. When some data is updated on the server, a message is typically sent over a WebSocket connection to be handled by the client. This provides a more robust, efficient alternative to continually polling your application for changes.
+
+To assist you in building these types of applications, Laravel makes it easy to "broadcast" your events over a WebSocket connection. Broadcasting your Laravel events allows you to share the same event names between your server-side code and your client-side JavaScript application.
+
+Laravel Echo is a JavaScript library that makes it painless to subscribe to channels and listen for events broadcast by Laravel. You may install Echo via the NPM package manager.
+
+## Official Documentation

+[![NPM Version][npm-version-image]][npm-url]
+[![NPM Downloads][npm-downloads-image]][npm-url]

+
+This is a large database of mime types and information about them.
+It consists of a single, public JSON file and does not include any logic,
+allowing it to remain as un-opinionated as possible with an API.
+It aggregates data from the following sources:
+
+- http://www.iana.org/assignments/media-types/media-types.xhtml
+- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
+- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types
+
+## Installation
+
+```bash
+npm install mime-db
+```
+
+### Database Download
+
+If you're crazy enough to use this in the browser, you can just grab the
+JSON file using [jsDelivr](https://www.jsdelivr.com/). It is recommended to
+replace `master` with [a release tag](https://github.com/jshttp/mime-db/tags)
+as the JSON format may change in the future.
+
+```
+https://cdn.jsdelivr.net/gh/jshttp/mime-db@master/db.json
+```
+
+## Usage
+
+```js
+var db = require('mime-db')
+
+// grab data on .js files
+var data = db['application/javascript']
+```
+
+## Data Structure
+
+The JSON file is a map lookup for lowercased mime types.
+Each mime type has the following properties:
+
+- `.source` - where the mime type is defined.
+    If not set, it's probably a custom media type.
+    - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
+    - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
+    - `nginx` - [nginx media types](http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
+- `.extensions[]` - known extensions associated with this mime type.
+- `.compressible` - whether a file of this type can be gzipped.
+- `.charset` - the default charset associated with this type, if any.
+
+If unknown, every property could be `undefined`.
+
+## Contributing
+
+To edit the database, only make PRs against `src/custom-types.json` or
+`src/custom-suffix.json`.
+
+The `src/custom-types.json` file is a JSON object with the MIME type as the
+keys and the values being an object with the following keys:
+
+- `compressible` - leave out if you don't know, otherwise `true`/`false` to
+  indicate whether the data represented by the type is typically compressible.
+- `extensions` - include an array of file extensions that are associated with
+  the type.
+- `notes` - human-readable notes about the type, typically what the type is.
+- `sources` - include an array of URLs of where the MIME type and the associated
+  extensions are sourced from. This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source);
+  links to type aggregating sites and Wikipedia are _not acceptable_.
+
+To update the build, run `npm run build`.
+
+### Adding Custom Media Types
+
+The best way to get new media types included in this library is to register
+them with the IANA. The community registration procedure is outlined in
+[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
+registered with the IANA are automatically pulled into this library.
+
+If that is not possible / feasible, they can be added directly here as a
+"custom" type. To do this, it is required to have a primary source that
+definitively lists the media type. If an extension is going to be listed as
+associateed with this media type, the source must definitively link the
+media type and extension as well.

+
+The ultimate javascript content-type utility.
+
+Similar to [the `mime@1.x` module](https://www.npmjs.com/package/mime), except:
+
+- __No fallbacks.__ Instead of naively returning the first available type,
+  `mime-types` simply returns `false`, so do
+  `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
+- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
+- No `.define()` functionality
+- Bug fixes for `.lookup(path)`
+
+Otherwise, the API is compatible with `mime` 1.x.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install mime-types
+```
+
+## Adding Types
+
+All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
+so open a PR there if you'd like to add mime types.
+
+## API
+
+```js
+var mime = require('mime-types')
+```
+
+All functions return `false` if input is invalid or not found.
+
+### mime.lookup(path)
+
+Lookup the content-type associated with a file.
+
+```js
+mime.lookup('json') // 'application/json'
+mime.lookup('.md') // 'text/markdown'
+mime.lookup('file.html') // 'text/html'
+mime.lookup('folder/file.js') // 'application/javascript'
+mime.lookup('folder/.htaccess') // false
+
+mime.lookup('cats') // false
+```
+
+### mime.contentType(type)
+
+Create a full content-type header given a content-type or extension.
+When given an extension, `mime.lookup` is used to get the matching
+content-type, otherwise the given content-type is used. Then if the
+content-type does not already have a `charset` parameter, `mime.charset`
+is used to get the default charset and add to the returned content-type.
+
+```js
+mime.contentType('markdown') // 'text/x-markdown; charset=utf-8'
+mime.contentType('file.json') // 'application/json; charset=utf-8'
+mime.contentType('text/html') // 'text/html; charset=utf-8'
+mime.contentType('text/html; charset=iso-8859-1') // 'text/html; charset=iso-8859-1'
+
+// from a full path
+mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
+```
+
+### mime.extension(type)
+
+Get the default extension for a content-type.
+
+```js
+mime.extension('application/octet-stream') // 'bin'
+```
+
+### mime.charset(type)
+
+Lookup the implied default charset of a content-type.
+
+```js
+mime.charset('text/markdown') // 'UTF-8'
+```
+
+### var type = mime.types[extension]
+
+A map of content-types by extension.
+
+### [extensions...] = mime.extensions[type]
+
+A map of extensions by content-type.

+
+A tiny, secure, URL-friendly, unique string ID generator for JavaScript.
+
+> “An amazing level of senseless perfectionism,
+> which is simply impossible not to respect.”
+
+* **Small.** 130 bytes (minified and gzipped). No dependencies.
+  [Size Limit] controls the size.
+* **Fast.** It is 2 times faster than UUID.
+* **Safe.** It uses hardware random generator. Can be used in clusters.
+* **Short IDs.** It uses a larger alphabet than UUID (`A-Za-z0-9_-`).
+  So ID size was reduced from 36 to 21 symbols.
+* **Portable.** Nano ID was ported
+  to [20 programming languages](#other-programming-languages).
+
+```js
+import { nanoid } from 'nanoid'
+model.id = nanoid() //=> "V1StGXR8_Z5jdHi6B-myT"
+```
+
+Supports modern browsers, IE [with Babel], Node.js and React Native.

+## 2.3.1 (2022-01-02)
+
+### Fixed
+
+* Fixes bug when a pattern containing an expression after the closing parenthesis (`/!(*.d).{ts,tsx}`) was incorrectly converted to regexp ([9f241ef](https://github.com/micromatch/picomatch/commit/9f241ef)).
+
+### Changed
+
+* Some documentation improvements ([f81d236](https://github.com/micromatch/picomatch/commit/f81d236), [421e0e7](https://github.com/micromatch/picomatch/commit/421e0e7)).
+
+## 2.3.0 (2021-05-21)
+
+### Fixed
+
+* Fixes bug where file names with two dots were not being matched consistently with negation extglobs containing a star ([56083ef](https://github.com/micromatch/picomatch/commit/56083ef))
+
+## 2.2.3 (2021-04-10)
+
+### Fixed
+
+* Do not skip pattern seperator for square brackets ([fb08a30](https://github.com/micromatch/picomatch/commit/fb08a30)).
+* Set negatedExtGlob also if it does not span the whole pattern ([032e3f5](https://github.com/micromatch/picomatch/commit/032e3f5)).
+
+## 2.2.2 (2020-03-21)
+
+### Fixed
+
+* Correctly handle parts of the pattern after parentheses in the `scan` method ([e15b920](https://github.com/micromatch/picomatch/commit/e15b920)).
+
+## 2.2.1 (2020-01-04)
+
+* Fixes [#49](https://github.com/micromatch/picomatch/issues/49), so that braces with no sets or ranges are now propertly treated as literals.
+
+## 2.2.0 (2020-01-04)
+
+* Disable fastpaths mode for the parse method ([5b8d33f](https://github.com/micromatch/picomatch/commit/5b8d33f))
+* Add `tokens`, `slashes`, and `parts` to the object returned by `picomatch.scan()`.
+
+## 2.1.0 (2019-10-31)

+<strong>Blazing fast and accurate glob matcher written in JavaScript.</strong></br>
+<em>No dependencies and full support for standard and extended Bash glob features, including braces, extglobs, POSIX brackets, and regular expressions.</em>
+</p>
+
+<br>
+<br>
+
+## Why picomatch?
+
+* **Lightweight** - No dependencies
+* **Minimal** - Tiny API surface. Main export is a function that takes a glob pattern and returns a matcher function.
+* **Fast** - Loads in about 2ms (that's several times faster than a [single frame of a HD movie](http://www.endmemo.com/sconvert/framespersecondframespermillisecond.php) at 60fps)
+* **Performant** - Use the returned matcher function to speed up repeat matching (like when watching files)
+* **Accurate matching** - Using wildcards (`*` and `?`), globstars (`**`) for nested directories, [advanced globbing](#advanced-globbing) with extglobs, braces, and POSIX brackets, and support for escaping special characters with `\` or quotes.
+* **Well tested** - Thousands of unit tests

+
+## Usage
+
+The main export is a function that takes a glob pattern and an options object and returns a function for matching strings.
+
+```js
+const pm = require('picomatch');
+const isMatch = pm('*.js');
+
+console.log(isMatch('abcd')); //=> false

+
+## Options
+
+### Picomatch options
+
+The following options may be used with the main `picomatch()` function or any of the methods on the picomatch API.
+
+| **Option** | **Type** | **Default value** | **Description** |
+| --- | --- | --- | --- |
+| `basename`            | `boolean`      | `false`     | If set, then patterns without slashes will be matched against the basename of the path if it contains slashes.  For example, `a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. |
+| `bash`                | `boolean`      | `false`     | Follow bash matching rules more strictly - disallows backslashes as escape characters, and treats single stars as globstars (`**`). |
+| `capture`             | `boolean`      | `undefined` | Return regex matches in supporting methods. |
+| `contains`            | `boolean`      | `undefined` | Allows glob to match any part of the given string(s). |
+| `cwd`                 | `string`       | `process.cwd()` | Current working directory. Used by `picomatch.split()` |
+| `debug`               | `boolean`      | `undefined` | Debug regular expressions when an error is thrown. |
+| `dot`                 | `boolean`      | `false`     | Enable dotfile matching. By default, dotfiles are ignored unless a `.` is explicitly defined in the pattern, or `options.dot` is true |
+| `expandRange`         | `function`     | `undefined` | Custom function for expanding ranges in brace patterns, such as `{a..z}`. The function receives the range values as two arguments, and it must return a string to be used in the generated regex. It's recommended that returned strings be wrapped in parentheses. |
+| `failglob`            | `boolean`      | `false`     | Throws an error if no matches are found. Based on the bash option of the same name. |
+| `fastpaths`           | `boolean`      | `true`      | To speed up processing, full parsing is skipped for a handful common glob patterns. Disable this behavior by setting this option to `false`. |
+| `flags`               | `string`      | `undefined` | Regex flags to use in the generated regex. If defined, the `nocase` option will be overridden. |
+| [format](#optionsformat) | `function` | `undefined` | Custom function for formatting the returned string. This is useful for removing leading slashes, converting Windows paths to Posix paths, etc. |
+| `ignore`              | `array\|string` | `undefined` | One or more glob patterns for excluding strings that should not be matched from the result. |
+| `keepQuotes`          | `boolean`      | `false`     | Retain quotes in the generated regex, since quotes may also be used as an alternative to backslashes.  |
+| `literalBrackets`     | `boolean`      | `undefined` | When `true`, brackets in the glob pattern will be escaped so that only literal brackets will be matched. |
+| `matchBase`           | `boolean`      | `false`     | Alias for `basename` |
+| `maxLength`           | `boolean`      | `65536`     | Limit the max length of the input string. An error is thrown if the input string is longer than this value. |
+| `nobrace`             | `boolean`      | `false`     | Disable brace matching, so that `{a,b}` and `{1..3}` would be treated as literal characters. |
+| `nobracket`           | `boolean`      | `undefined` | Disable matching with regex brackets. |
+| `nocase`              | `boolean`      | `false`     | Make matching case-insensitive. Equivalent to the regex `i` flag. Note that this option is overridden by the `flags` option. |
+| `nodupes`             | `boolean`      | `true`      | Deprecated, use `nounique` instead. This option will be removed in a future major release. By default duplicates are removed. Disable uniquification by setting this option to false. |
+| `noext`               | `boolean`      | `false`     | Alias for `noextglob` |
+| `noextglob`           | `boolean`      | `false`     | Disable support for matching with extglobs (like `+(a\|b)`) |
+| `noglobstar`          | `boolean`      | `false`     | Disable support for matching nested directories with globstars (`**`) |
+| `nonegate`            | `boolean`      | `false`     | Disable support for negating with leading `!` |
+| `noquantifiers`       | `boolean`      | `false`     | Disable support for regex quantifiers (like `a{1,2}`) and treat them as brace patterns to be expanded. |
+| [onIgnore](#optionsonIgnore) | `function` | `undefined` | Function to be called on ignored items. |
+| [onMatch](#optionsonMatch) | `function` | `undefined` | Function to be called on matched items. |
+| [onResult](#optionsonResult) | `function` | `undefined` | Function to be called on all items, regardless of whether or not they are matched or ignored. |
+| `posix`               | `boolean`      | `false`     | Support POSIX character classes ("posix brackets"). |
+| `posixSlashes`        | `boolean`      | `undefined` | Convert all slashes in file paths to forward slashes. This does not convert slashes in the glob pattern itself |
+| `prepend`             | `boolean`      | `undefined` | String to prepend to the generated regex used for matching. |
+| `regex`               | `boolean`      | `false`     | Use regular expression rules for `+` (instead of matching literal `+`), and for stars that follow closing parentheses or brackets (as in `)*` and `]*`). |
+| `strictBrackets`      | `boolean`      | `undefined` | Throw an error if brackets, braces, or parens are imbalanced. |
+| `strictSlashes`       | `boolean`      | `undefined` | When true, picomatch won't match trailing slashes with single stars. |
+| `unescape`            | `boolean`      | `undefined` | Remove backslashes preceding escaped characters in the glob pattern. By default, backslashes are retained. |
+| `unixify`             | `boolean`      | `undefined` | Alias for `posixSlashes`, for backwards compatibility. |
+
+picomatch has automatic detection for regex positive and negative lookbehinds. If the pattern contains a negative lookbehind, you must be using Node.js >= 8.10 or else picomatch will throw an error.
+
+### Scan Options
+
+In addition to the main [picomatch options](#picomatch-options), the following options may also be used with the [.scan](#scan) method.
+
+| **Option** | **Type** | **Default value** | **Description** |
+| --- | --- | --- | --- |
+| `tokens` | `boolean` | `false` | When `true`, the returned object will include an array of tokens (objects), representing each path "segment" in the scanned glob pattern |
+| `parts` | `boolean` | `false` | When `true`, the returned object will include an array of strings representing each path "segment" in the scanned glob pattern. This is automatically enabled when `options.tokens` is true |
+
+**Example**
+
+```js
+const picomatch = require('picomatch');
+const result = picomatch.scan('!./foo/*.js', { tokens: true });
+console.log(result);
+// {
+//   prefix: '!./',
+//   input: '!./foo/*.js',
+//   start: 3,
+//   base: 'foo',
+//   glob: '*.js',
+//   isBrace: false,
+//   isBracket: false,
+//   isGlob: true,
+//   isExtglob: false,
+//   isGlobstar: false,
+//   negated: true,
+//   maxDepth: 2,
+//   tokens: [
+//     { value: '!./', depth: 0, isGlob: false, negated: true, isPrefix: true },
+//     { value: 'foo', depth: 1, isGlob: false },
+//     { value: '*.js', depth: 1, isGlob: true }
+//   ],
+//   slashes: [ 2, 6 ],
+//   parts: [ 'foo', '*.js' ]
+// }
+```
+
+<br>
+
+### Options Examples
+
+#### options.expandRange
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+Custom function for expanding ranges in brace patterns. The [fill-range](https://github.com/jonschlinkert/fill-range) library is ideal for this purpose, or you can use custom code to do whatever you need.
+
+**Example**
+
+The following example shows how to create a glob that matches a folder
+
+```js
+const fill = require('fill-range');
+const regex = pm.makeRe('foo/{01..25}/bar', {
+  expandRange(a, b) {
+    return `(${fill(a, b, { toRegex: true })})`;
+  }
+});
+
+console.log(regex);
+//=> /^(?:foo\/((?:0[1-9]|1[0-9]|2[0-5]))\/bar)$/
+
+console.log(regex.test('foo/00/bar'))  // false
+console.log(regex.test('foo/01/bar'))  // true
+console.log(regex.test('foo/10/bar')) // true
+console.log(regex.test('foo/22/bar')) // true
+console.log(regex.test('foo/25/bar')) // true
+console.log(regex.test('foo/26/bar')) // false
+```
+
+#### options.format
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+Custom function for formatting strings before they're matched.
+
+**Example**
+
+```js
+// strip leading './' from strings
+const format = str => str.replace(/^\.\//, '');
+const isMatch = picomatch('foo/*.js', { format });
+console.log(isMatch('./foo/bar.js')); //=> true
+```
+
+#### options.onMatch
+
+```js
+const onMatch = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onMatch });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```
+
+#### options.onIgnore
+
+```js
+const onIgnore = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onIgnore, ignore: 'f*' });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```
+
+#### options.onResult
+
+```js
+const onResult = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onResult, ignore: 'f*' });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```

+## Globbing features
+
+* [Basic globbing](#basic-globbing) (Wildcard matching)
+* [Advanced globbing](#advanced-globbing) (extglobs, posix brackets, brace matching)
+
+### Basic globbing
+
+| **Character** | **Description** |
+| --- | --- |
+| `*` | Matches any character zero or more times, excluding path separators. Does _not match_ path separators or hidden files or directories ("dotfiles"), unless explicitly enabled by setting the `dot` option to `true`. |
+| `**` | Matches any character zero or more times, including path separators. Note that `**` will only match path separators (`/`, and `\\` on Windows) when they are the only characters in a path segment. Thus, `foo**/bar` is equivalent to `foo*/bar`, and `foo/a**b/bar` is equivalent to `foo/a*b/bar`, and _more than two_ consecutive stars in a glob path segment are regarded as _a single star_. Thus, `foo/***/bar` is equivalent to `foo/*/bar`. |
+| `?` | Matches any character excluding path separators one time. Does _not match_ path separators or leading dots.  |
+| `[abc]` | Matches any characters inside the brackets. For example, `[abc]` would match the characters `a`, `b` or `c`, and nothing else. |
+
+#### Matching behavior vs. Bash
+
+Picomatch's matching features and expected results in unit tests are based on Bash's unit tests and the Bash 4.3 specification, with the following exceptions:
+
+* Bash will match `foo/bar/baz` with `*`. Picomatch only matches nested directories with `**`.
+* Bash greedily matches with negated extglobs. For example, Bash 4.3 says that `!(foo)*` should match `foo` and `foobar`, since the trailing `*` bracktracks to match the preceding pattern. This is very memory-inefficient, and IMHO, also incorrect. Picomatch would return `false` for both `foo` and `foobar`.
+
+<br>
+
+### Advanced globbing
+
+* [extglobs](#extglobs)
+* [POSIX brackets](#posix-brackets)
+* [Braces](#brace-expansion)
+
+#### Extglobs
+
+| **Pattern** | **Description** |
+| --- | --- |
+| `@(pattern)` | Match _only one_ consecutive occurrence of `pattern` |
+| `*(pattern)` | Match _zero or more_ consecutive occurrences of `pattern` |
+| `+(pattern)` | Match _one or more_ consecutive occurrences of `pattern` |
+| `?(pattern)` | Match _zero or **one**_ consecutive occurrences of `pattern` |
+| `!(pattern)` | Match _anything but_ `pattern` |
+
+**Examples**
+
+```js
+const pm = require('picomatch');
+
+// *(pattern) matches ZERO or more of "pattern"
+console.log(pm.isMatch('a', 'a*(z)')); // true
+console.log(pm.isMatch('az', 'a*(z)')); // true
+console.log(pm.isMatch('azzz', 'a*(z)')); // true
+
+// +(pattern) matches ONE or more of "pattern"
+console.log(pm.isMatch('a', 'a*(z)')); // true
+console.log(pm.isMatch('az', 'a*(z)')); // true
+console.log(pm.isMatch('azzz', 'a*(z)')); // true
+
+// supports multiple extglobs
+console.log(pm.isMatch('foo.bar', '!(foo).!(bar)')); // false
+
+// supports nested extglobs
+console.log(pm.isMatch('foo.bar', '!(!(foo)).!(!(bar))')); // true
+```
+
+#### POSIX brackets
+
+POSIX classes are disabled by default. Enable this feature by setting the `posix` option to true.
+
+**Enable POSIX bracket support**
+
+```js
+console.log(pm.makeRe('[[:word:]]+', { posix: true }));
+//=> /^(?:(?=.)[A-Za-z0-9_]+\/?)$/
+```
+
+**Supported POSIX classes**
+
+The following named POSIX bracket expressions are supported:
+
+* `[:alnum:]` - Alphanumeric characters, equ `[a-zA-Z0-9]`
+* `[:alpha:]` - Alphabetical characters, equivalent to `[a-zA-Z]`.
+* `[:ascii:]` - ASCII characters, equivalent to `[\\x00-\\x7F]`.
+* `[:blank:]` - Space and tab characters, equivalent to `[ \\t]`.
+* `[:cntrl:]` - Control characters, equivalent to `[\\x00-\\x1F\\x7F]`.
+* `[:digit:]` - Numerical digits, equivalent to `[0-9]`.
+* `[:graph:]` - Graph characters, equivalent to `[\\x21-\\x7E]`.
+* `[:lower:]` - Lowercase letters, equivalent to `[a-z]`.
+* `[:print:]` - Print characters, equivalent to `[\\x20-\\x7E ]`.
+* `[:punct:]` - Punctuation and symbols, equivalent to `[\\-!"#$%&\'()\\*+,./:;<=>?@[\\]^_`{|}~]`.
+* `[:space:]` - Extended space characters, equivalent to `[ \\t\\r\\n\\v\\f]`.
+* `[:upper:]` - Uppercase letters, equivalent to `[A-Z]`.
+* `[:word:]` -  Word characters (letters, numbers and underscores), equivalent to `[A-Za-z0-9_]`.
+* `[:xdigit:]` - Hexadecimal digits, equivalent to `[A-Fa-f0-9]`.
+
+See the [Bash Reference Manual](https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html) for more information.
+
+### Braces
+
+Picomatch does not do brace expansion. For [brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html) and advanced matching with braces, use [micromatch](https://github.com/micromatch/micromatch) instead. Picomatch has very basic support for braces.
+
+### Matching special characters as literals
+
+If you wish to match the following special characters in a filepath, and you want to use these characters in your glob pattern, they must be escaped with backslashes or quotes:
+
+**Special Characters**
+
+Some characters that are used for matching in regular expressions are also regarded as valid file path characters on some platforms.
+
+To match any of the following characters as literals: `$^*+?()[]
+
+Examples:
+
+```js
+console.log(pm.makeRe('foo/bar \\(1\\)'));
+console.log(pm.makeRe('foo/bar \\(1\\)'));
+```
+
+<br>

+
+## Philosophies
+
+The goal of this library is to be blazing fast, without compromising on accuracy.
+
+**Accuracy**
+
+The number one of goal of this library is accuracy. However, it's not unusual for different glob implementations to have different rules for matching behavior, even with simple wildcard matching. It gets increasingly more complicated when combinations of different features are combined, like when extglobs are combined with globstars, braces, slashes, and so on: `!(**/{a,b,*/c})`.
+
+Thus, given that there is no canonical glob specification to use as a single source of truth when differences of opinion arise regarding behavior, sometimes we have to implement our best judgement and rely on feedback from users to make improvements.
+
+**Performance**
+
+Although this library performs well in benchmarks, and in most cases it's faster than other popular libraries we benchmarked against, we will always choose accuracy over performance. It's not helpful to anyone if our library is faster at returning the wrong answer.

+PostCSS is a tool for transforming styles with JS plugins.
+These plugins can lint your CSS, support variables and mixins,
+transpile future CSS syntax, inline images, and more.
+
+PostCSS is used by industry leaders including Wikipedia, Twitter, Alibaba,
+and JetBrains. The [Autoprefixer] and [Stylelint] PostCSS plugins is one of the most popular CSS tools.

+[![Build Status](https://travis-ci.org/Rob--W/proxy-from-env.svg?branch=master)](https://travis-ci.org/Rob--W/proxy-from-env)

+
+`proxy-from-env` is a Node.js package that exports a function (`getProxyForUrl`)
+that takes an input URL (a string or
+[`url.parse`](https://nodejs.org/docs/latest/api/url.html#url_url_parsing)'s
+return value) and returns the desired proxy URL (also a string) based on
+standard proxy environment variables. If no proxy is set, an empty string is
+returned.
+
+It is your responsibility to actually proxy the request using the given URL.
+
+Installation:
+
+```sh
+npm install proxy-from-env
+```
+
+## Example
+This example shows how the data for a URL can be fetched via the
+[`http` module](https://nodejs.org/api/http.html), in a proxy-aware way.
+
+```javascript
+var http = require('http');
+var parseUrl = require('url').parse;
+var getProxyForUrl = require('proxy-from-env').getProxyForUrl;
+
+var some_url = 'http://example.com/something';
+
+// // Example, if there is a proxy server at 10.0.0.1:1234, then setting the
+// // http_proxy environment variable causes the request to go through a proxy.
+// process.env.http_proxy = 'http://10.0.0.1:1234';
+// 
+// // But if the host to be proxied is listed in NO_PROXY, then the request is
+// // not proxied (but a direct request is made).
+// process.env.no_proxy = 'example.com';
+
+var proxy_url = getProxyForUrl(some_url);  // <-- Our magic.
+if (proxy_url) {
+  // Should be proxied through proxy_url.
+  var parsed_some_url = parseUrl(some_url);
+  var parsed_proxy_url = parseUrl(proxy_url);
+  // A HTTP proxy is quite simple. It is similar to a normal request, except the
+  // path is an absolute URL, and the proxied URL's host is put in the header
+  // instead of the server's actual host.
+  httpOptions = {
+    protocol: parsed_proxy_url.protocol,
+    hostname: parsed_proxy_url.hostname,
+    port: parsed_proxy_url.port,
+    path: parsed_some_url.href,
+    headers: {
+      Host: parsed_some_url.host,  // = host name + optional port.
+    },
+  };
+} else {
+  // Direct request.
+  httpOptions = some_url;
+}
+http.get(httpOptions, function(res) {
+  var responses = [];
+  res.on('data', function(chunk) { responses.push(chunk); });
+  res.on('end', function() { console.log(responses.join(''));  });
+});
+
+```
+
+## Environment variables
+The environment variables can be specified in lowercase or uppercase, with the
+lowercase name having precedence over the uppercase variant. A variable that is
+not set has the same meaning as a variable that is set but has no value.
+
+### NO\_PROXY
+
+`NO_PROXY` is a list of host names (optionally with a port). If the input URL
+matches any of the entries in `NO_PROXY`, then the input URL should be fetched
+by a direct request (i.e. without a proxy).
+
+Matching follows the following rules:
+
+- `NO_PROXY=*` disables all proxies.
+- Space and commas may be used to separate the entries in the `NO_PROXY` list.
+- If `NO_PROXY` does not contain any entries, then proxies are never disabled.
+- If a port is added after the host name, then the ports must match. If the URL
+  does not have an explicit port name, the protocol's default port is used.
+- Generally, the proxy is only disabled if the host name is an exact match for
+  an entry in the `NO_PROXY` list. The only exceptions are entries that start
+  with a dot or with a wildcard; then the proxy is disabled if the host name
+  ends with the entry.
+
+See `test.js` for examples of what should match and what does not.
+
+### \*\_PROXY
+
+The environment variable used for the proxy depends on the protocol of the URL.
+For example, `https://example.com` uses the "https" protocol, and therefore the
+proxy to be used is `HTTPS_PROXY` (_NOT_ `HTTP_PROXY`, which is _only_ used for
+http:-URLs).
+
+The library is not limited to http(s), other schemes such as
+`FTP_PROXY` (ftp:),
+`WSS_PROXY` (wss:),
+`WS_PROXY` (ws:)
+are also supported.
+
+If present, `ALL_PROXY` is used as fallback if there is no other match.
+
+
+## External resources
+The exact way of parsing the environment variables is not codified in any
+standard. This library is designed to be compatible with formats as expected by
+existing software.
+The following resources were used to determine the desired behavior:

+
+## 7.0.3 (2021-01-25)
+
+[UPDATED] Bumped version of faye-websocket (used only by the node runtime) from
+0.9.4 to 0.11.3. Thanks to @Akhawais for the PR.
+
+[UPDATED] Bumped version of @react-native-community/netinfo (used only by the
+react-native runtime) from 4.1.1 to 5.9.7. Thanks to @Yinabled for the PR.
+
+[ADDED] We were missing a react-native key in `package.json`. Thanks to @giaset
+for the PR
+
+[ADDED] Support for importing the worker builds (solving issue #499)
+
+## 7.0.2 (2020-11-26)
+
+[FIXED] Removes `AuthInfo` type from react-native and with-encryption builds.
+This type was removed everywhere else in v7.0.0. See [issue
+512](https://github.com/pusher/pusher-js/issues/512)
+
+## 7.0.1 (2020-11-02)
+
+[FIXED] Channels no longer get stuck in the `subscriptionPending` state
+after a failed request to an auth endpoint. [Fixes Issue
+255](https://github.com/pusher/pusher-js/issues/255)
+
+## 7.0.0 (2020-07-30)
+
+[UPDATED] Type signatures for authorizer callback. Previously the authorizer
+callback had 2 arguments, the first was a boolean indicating that the second
+was an error. Switched for a more conventional `function(err, data)` signature.
+**This is a breaking change, if you use a custom authorizer**
+
+[UPDATED] Types of errors emitted on `pusher:subscription_error` events.
+Previously this event just contained the status code the auth endpoint
+returned. This was replaced with a (hopefully) more error object with a message
+and a `status` key.
+**This is a breaking change, if you depend on the status in the
+`pusher:subscription_error` event**
+
+[FIXED] Stop wrapping websocket errors multiple times. [Fixes issue
+464](https://github.com/pusher/pusher-js/issues/464)
+**This might be a breaking change, if you depend on the structure of `'error'` events
+emitted by `pusher.connection`**
+
+[FIXED] Stop swallowing errors thrown by handlers on encrypted channels.
+Previously errors thrown by handlers bound to encrypted channels were caught
+and ignored. This was unintentional and undesirable. [Fixes Issue
+437](https://github.com/pusher/pusher-js/issues/437)
+
+## 6.0.3 (2020-05-14)
+
+[FIXED] Added typescript declarations for the pusher-js/with-encryption build
+
+[REMOVED] Unnecessary dummy tweetnacl types for react-native (thanks to
+@dmitrybirin)
+
+[UPDATED] Copyright years (thanks to @annzenkina)
+
+## 6.0.2 (2020-04-30)
+
+[FIXED] React-native import broken in release 6.0.1
+
+## 6.0.1 (2020-04-30)
+
+[CHANGED] Moved tweetnacl from `devDependencies` to `dependencies`. No
+additional code is included in the bundle, but this gives the typescript
+compiler access to the tweetnacl types
+
+[FIXED] Typescript declarations for react-native. These were supposed to be
+included in 6.0.0 but the commit was missed
+
+## 6.0.0 (2020-04-27)
+
+[CHANGED] The default builds for web and worker no longer support encrypted
+channels. To use encrypted channels in web/worker you must import
+`pusher-js/with-encryption` or use the
+`pusher-with-encryption.js`/`pusher-with-encryption.min.js` bundles
+
+[CHANGED] `forceTLS` now defaults to `true`
+
+[REMOVED] the `encrypted` option - this was deprecated in `4.3.0`. The library
+defaults to TLS anyway. Setting `encrypted` to `false` will **NOT** change
+behaviour
+
+[FIXED] `activityTimeout` and `pongTimeout` options now work as described in
+the docs.
+
+[NEW] Typescript declarations for react-native
+
+[NEW] Support for encrypted-channels in react-native and workers
+
+## 5.1.1 (2020-02-12)
+
+[FIXED] An issue with typescript declarations which caused builds to fail on
+typescript projects dependent on pusher-js
+
+## 5.1.0 (2020-02-11)
+
+[NEW] Include typescript declarations
+
+[CHANGED] Make stats opt in rather than opt out - Previously we sent some
+metrics about connection strategies to stats.pusher.com by default, it could be
+disabled by passing the `disableStats` option. This functionality is now off by
+default and can be enabled by passing the `enableStats` option
+
+[FIXED] An issue where local tests would hang for 300s if a browser wasn't
+available
+
+## 5.0.3 (2019-11-18)
+
+[NEW] Log a warning when there is an auth error
+
+[CHANGED] Default logger now uses console.warn and console.error
+
+[CHANGED] Improved log messages
+
+## 5.0.2 (2019-09-25)
+
+[FIXED] Utilise new API for @react-native-community/netinfo suppressing
+deprecation warnings
+
+[CHANGED] output an ES6 module from typescript to allow webpack to optimise the
+bundle more effectively (thanks to @stof for this change)
+
+[CHANGED] Use prettier to format source
+
+## 5.0.1 (2019-09-02)
+
+[FIXED] We no longer include an unnecessary Buffer polyfill in bundles
+
+## 5.0.0 (2019-07-19)
+
+This is a major version bump but should only contain breaking change for
+react-native users.
+
+[CHANGED] The react-native build now assumes @react-native-community/netinfo is
+available in the host project. This change was necessary since netinfo was
+removed from react-native core.
+
+[CHANGED] The reconnect strategy is no longer built with a DSL. This makes the
+code much more easily optimised by the javascript engine and should improve
+load times significantly. Thanks to @stof for his contribution.
+
+[CHANGED] The project is now built with recent versions of webpack and
+typescript. All other build deps were updated and the build process was
+simplified.
+
+[FIXED] An issue that broke encrypted channels in node has been resolved
+
+[FIXED] Some consistently flaky tests were fixed and we switched to headless
+browsers for test runs where possible (including in CI).
+
+[CHANGED] The node dependencies are now bundled in the node dist file so that
+web/react-native users don't need to install unnecessary dependencies
+
+## 4.4.0 (2019-02-14)
+
+[NEW] Callbacks bound to client events on presence channels will be called with an extra argument containing the `user_id` of the message sender
+
+[NEW] Warn when trying to trigger client-events to a channel that isn't subscribed
+
+## 4.3.1 (2018-09-03)
+
+[FIXED] Honour protocol error codes received after connection succeeds
+
+## 4.3.0 (2018-08-13)
+
+[NEW] This release adds support for end to end encrypted channels, a new feature for Channels. Read more [in our docs](https://pusher.com/docs/client_api_guide/client_encrypted_channels).
+
+[DEPRECATED] Renamed `encrypted` option to `forceTLS` - `encrypted` will still work!
+
+## 4.2.2 (2018-01-04)
+
+[FIXED] Do not warn about a missing cluster when the host is explicitly set.
+
+[FIXED] Only log with a custom logger when configured (prevents double
+logging).
+
+[FIXED] Update React Native NetInfo usage due to deprecated modules.
+
+[NEW] Add `wsPath` option (see README.md for details).
+
+Many thanks to @sunweiyang, @rajivm and @WillSewell for their contributions!
+
+## 4.2.1 (2017-09-28)
+
+[FIXED] Correct version numbers in file headers (v4.2.0 still showed 4.1.0).
+
+## 4.2.0 (2017-09-28)
+
+[FIXED] Fixed an issue where pusher-js would not attempt to subscribe to
+channels that were in the process of being subscribed to when the connection
+failed.
+
+[FIXED] Does not attempt to call `handlesActivityChecks` on an undefined
+connection instance anymore. Fixes issues #82 and #233.
+
+[NEW] More helpful error messages can now be logged, with URLs.
+
+[CHANGED] Various improvements in README.md.
+
+Many thanks to @hengwoon, @leesio, @juliangruber and Heng for their
+contributions to this release!

+[FIXED] Include minified files when installing with Bower.
+
+[CHANGED] Change `pusher` to `socket` for instance names in the readme.

+
+## 3.2.3 (2016-10-22)

+[NEW] Cancelled subscriptions are now re-instated on subsequent `subscribe`
+calls, allowing arbitrary chains of `subscribe`/`unsubscribe` calls, where the
+final method is always respected regardless of the timings.
+See [PR 201](https://github.com/pusher/pusher-js/pull/201) for details.
+
+## 3.2.2 (2016-10-03)

+
+[CHANGED] Improved connection timeout strategy.
+
+## 1.12.4 (2012-10-08)
+
+[NEW] Added experimental fallback used when Flash fallback fails.
+
+## 1.12.3 (2012-10-01)
+
+[FIXED] Error when Flash fallback files are served cross-domain.
+
+## 1.12.2 (2012-07-18)
+
+[FIXED] Issues with Flash fallback when port 843 is blocked.
+
+[FIXED] Binding to events with names of Object's native methods.
+

+
+[CHANGED] The error argument passed into `socket.onerror()` is included with the error emitted to the user.
+
+[FIXED] impermanentlyClosing to impermanentlyClosing state machine transition.
+
+## 1.12.0 (2012-04-14)
+
+[NEW] Use `channel.members.me` to get the id and info for the local presence user.  See the docs for more information: http://pusher.com/docs
+
+[NEW] Send extra headers and query parameters with the private/presence channel authentication requests sent to your server.  This is useful for, amongst other things, frameworks that require cross-site request forgery validation.  See the docs for more information: http://pusher.com/docs
+
+[FIXED] `channel.subscribed` not set to `false` when `disconnect` event occurs on the connection.
+
+[UPGRADE] The linked version of web-socket-js. This includes a switch to the WebSocket version defined in RFC 6455.  For the full list of changes in web-socket-js, see <https://github.com/gimite/web-socket-js/compare/bb5797cad5244dc86410e35726ef886bbc49afe9...2ee87e910e92f2366d562efebbbec96349924df3>.
+
+[REMOVED] `channel.members.add()`, `channel.members.remove()` and `channel.members.clear()`.
+
+## 1.11.2 (2012-03-15)
+
+[FIXED] Mobile Safari crashing after receiving data on closed connection.
+
+[FIXED] Attempt to transition from impermanentlyClosing to connected.
+
+## 1.11.1 (2012-03-09)
+
+[NEW] Unit tests run twice as fast.
+
+[CHANGED] The reconnection attempt following a dropped connection will happen a minimum of one second after the connection was previously established.
+
+[FIXED] Calling connect after some failed connection attempts means the attempt to connect is delayed.
+
+[FIXED] Connection closing after calling disconnect is not emitted to the developer.
+
+## 1.11.0 (2012-01-03)
+
+[NEW] You can now unbind from an event.
+
+[NEW] Internal errors are now logged with `console.error` if available. You can override this behaviour by modifying the `Pusher.warn` function.
+
+[NEW] Warning logged to `console.error` in the following cases: no api key supplied to initialiser, authentication failure connecting to private/presence channel, attempt to connect using `ws://` for application which have designated themselves as secure only, or unexpected errors returned by Pusher.
+
+[NEW] Stale connections between the Pusher client and server are now detected and re-established.
+
+[CHANGED] You may no longer bind to pusher_internal events.
+
+[REMOVED] Pusher.Channel.is_private
+
+[REMOVED] Pusher.Channel.is_presence
+
+## 1.10.1 (2011-12-1)
+
+[NEW] Changed `channel.trigger()` to return a boolean indicating whether the message was actually sent.
+
+[NEW] Private and public channels now emit `pusher:subscription_succeeded` events.  This is consistent with presence channels.
+
+[CHANGED] Renamed the `subscription_error` event to `pusher:subscription_error`.
+
+## 1.9.6 (2011-11-16)
+
+[FIXED] Issue in Mozilla Firefox 8, where making a connection to non-ssl websocket endpoint from a secure page results in a security exception.
+
+## 1.9.5 (2011-11-15)
+
+[FIXED] NetInfo listening as to not clobber the window.ononline and window.onoffline variables. Fixes issue #9.
+
+[FIXED] Loading of web-socket-js on Mozilla browsers with MozWebSocket, issue #10.
+
+[UPGRADE] Test framework to run in most browsers (IE6+, FF3+, Opera 11.52+, Safari, Chrome). Includes various other improvements to tests and testing infrastructure.
+
+[NEW] Smarter SSL only error detection. If a connection is closed by pusher with an error saying that the app is in SSL only mode, then we will now force all future connection attempts to use SSL.
+
+[NEW] Added guards around the JSON.parse calls in the Ajax Authoriser for private and presence channels.
+
+## 1.9.4 (2011-09-12)
+
+[FIX] Fixed bug which meant that presence channels only worked correctly when `user_info` was supplied. It's now possible to use presence channels without specifying `user_info` (`user_id` is required).
+
+## 1.9.3 (2011-08-19)
+
+[FIX] Fixed JSON dependency loading properly, rather than bundling it always.
+
+## 1.9.2 (2011-08-04)
+
+[NEW] Cleverer reconnection behaviour.
+
+If Connection is connected and the window.ononffline event is fired, this indicates that the computer has lost its connection to the local router.  In response, the Connection immediately closes the socket.
+
+If Connection is disconnected and waiting to reattempt a connection, and the window.ononline event is fired, the Connection tries to connect immediately, rather than waiting for the current waiting period to elapse.
+
+If the window is about to attempt a connection and the window.navigator.onLine variable is false, the Connection immediately goes to the unavailable state.
+
+Note: window.ononline, window.onoffline and window.navigator.onLine are only supported by some browsers.
+
+[NEW] If channel authentication AJAX request returns a status code that is not 200, a `subscription_error` event is triggered.  The `subscription_error` can be bound to so that the library user can respond to the failure.
+
+[FIX] Works with IE7 again, after being broken in 1.9.0.
+
+[FIX] Traffic Light connection status demo works in installations of Firefox 3.6 without Firebug.
+
+## 1.9.1 (2011-07-18)
+
+[FIX] Client events triggering fixed (broken by 1.9.0)
+
+[FIX] Removed verbose logging of internal state machine transitions
+
+## 1.9.0 (2011-07-15)
+
+[NEW] New API to allow binding to changes in connection state. See blog post for details.
+
+[NEW] Support for Firefox 6 native WebSocket using MozWebSocket prefix
+
+[REMOVED] Old connection state events: `pusher:connection_established`, `pusher:connection_failed`, `pusher:connection_disconnected`.
+
+[CHANGED] Socket id now accessed via `pusher.connection.socket_id` rather than `pusher.socket_id`.
+
+## 1.8.6 (2011-08-19)
+
+[NEW] Support for Firefox 6 native WebSocket using MozWebSocket prefix
+
+## 1.8.5 (2011-06-18)
+
+[FIX] Fix the fact that member was being added to the global scope
+
+[CHANGE] `Pusher.log` function now always receives a single string argument rather than multiple arguments, making it easier to use. If you want more control, you can over-ride `Pusher.debug`
+
+## 1.8.4 (2011-06-18)
+
+[FIX] When using multiple presence channels concurrently, the members object for each channel now operates as expected
+
+## 1.8.3 (2011-04-19)
+
+[FIX] Delay Pusher initialization until document.body is defined. This fixes an issue in Firefox < 4 & IE which occasionally caused a "document.body is null"  error when loading the flash fallback.
+
+[UPGRADE] Upgraded linked version of web-socket-js. Amongst other things this removes the dependency on FABridge and reduces the minified size of fallback dependencies by 13KB.
+For the full list of changes in web-socket-js see <https://github.com/gimite/web-socket-js/compare/6640d9d806972ea1720a273d09e8919464bcd131...bb5797cad5244dc86410e35726ef886bbc49afe9>
+
+## 1.8.2 (2011-03-29)
+
+[BUGFIX] When loaded onto a HTTPS page, load pusher dependencies from HTTPS.
+
+## 1.8.1 (2011-03-21)
+
+[BUGFIX] Minor fix which could have allowed `member_removed` to be triggered with nil.
+
+[CHANGE] Increased default connection timeout to reduce likelyhood of timeouts on first connection attempt. This is now configurable as `Pusher.connection_timeout`.
+
+## 1.8.0 (2011-02-10)
+
+[NEW] Support triggering client events with new API
+
+    channel.trigger('client-myeventname', {
+      some: 'data'
+    })
+
+[NEW] Support for new socket presence interface, and changed javascript API. The `subscription_succeeded` event now returns an iterator object:
+
+    presence_channel.bind('pusher:subscription_succeeded', function(members) {
+     members.each(function(member) {
+       console.log(member.id, member.info)
+     })
+    })
+
+Also, the member object passed to `member_added` and `member_removed` now has attributes `id` and `info` rather than `user_id` and `user_info`.
+
+[CHANGED] Improved javascript debug console logging.
+
+## 1.7.6 (2011-03-29)
+
+[BUGFIX] When loaded onto a HTTPS page, load pusher dependencies from HTTPS [backported from 1.8.2].
+
+## 1.7.5 (2011-03-21)
+
+[CHANGE] Increased default connection timeout to reduce likelyhood of timeouts on first connection attempt. This is now configurable as `Pusher.connection_timeout` [backported from 1.8.1].
+
+## 1.7.4 (2011-02-09)
+
+[FIXED] Javascript error was raised in the case that neither native WebSockets nor Flash were available.
+
+[FIXED] Updated linked version of web-socket-js, which fixes issue connecting from Android, allows connection attempts to timeout and retry correctly. For full details see <https://github.com/gimite/web-socket-js/compare/2776dcfbf7847a5e19505432d8d63f8814e37b52...6640d9d806972ea1720a273d09e8919464bcd131>
+
+## 1.7.3 (2011-02-01)
+
+[FIXED] Pusher could fail to initialize in IE 7 & 8 when dependencies cached
+
+## 1.7.2 (2011-01-25)
+
+[FIXED] pusher.min.js now loads minified rather than unminified dependencies.
+
+[CHANGED] Using JBundle for bundling the distribution. This should not in any way affect the minified files, it just simplifies building them.
+
+## 1.7.1
+
+Wrap timeout around connections so that silently hanging connections are retried.
+
+More robust reconnection logic, with initially shorter reconnect delay, but with increasing backoff.
+
+## 1.7.0
+
+Encrypted apps: apps can now be configured to connect via SSL only. There is a corresponding setting in your dashboard which will reject non encrypted connections.
+
+    var pusher = new Pusher('your-key', {
+      encrypted: true
+    })
+
+Note that the second argument to the Pusher constructor for setting channel names has been removed. You should use `pusher.subscribe instead`. THIS NO LONGER WORKS:
+
+    var pusher = new Pusher('your-key', 'channel-name') # DOES NOT WORK
+
+## 1.6.4
+
+JSONp support for presence and private channels
+
+Configurable transport for channel auths. JSONp allows for cross-domain channel authorization (ie. embedable widgets)
+
+    Pusher.channel_auth_transport = 'jsonp';
+
+The default is Ajax for backwards compatibility. Ajax mode POSTS to Pusher.channel_auth_endpoint, whereas JSONp GETs.
+
+For JSONp to work, your server must wrap the response in the callback name provided as a query parameter. Ruby example (using Pusher Gem) and Rails:
+
+    auth = Pusher[channel_name].authenticate(params[:socket_id], {
+      :user_id => current_user.id,
+      :user_info => {:name => current_user.name}
+    })
+
+    render :text => params[:callback] + "(" + JSON.generate(auth) + ");"
+
+## 1.6.3
+
+Fixed presence bug for removed duplicate members.
+
+If I connect as the same user in different browser windows or tabs, clients should trigger remove that member from a channel's member list only when the last window/tab is closed.
+
+See http://pusher.tenderapp.com/discussions/questions/11-presence-of-friends for discussion.
+
+## 1.6.2
+
+Dynamically load Javascript and Flash dependencies only for browsers that need them. Including pusher.js will:
+
+IE: require JSON2, require and activate Flash fallback.
+Firefox 3.6x: require and activate Flash fallback
+Chrome, Safari: don't require anything. These browsers already have WebSocket and JSON support.
+
+This saves a lot of bandwidth and makes page loads faster.
+
+## 1.6
+
+Initial Presence support. Subscribing to presence channels allows you to respond to people entering and leaving the channel in your UI, to show who is has a connection open. More documentation here: http://pusherapp.com/docs/presence.
+
+## 1.5
+
+Updated the library to use a version of the swf file hosted by Pusher. This makes it more convenient to integrate and avoids version conflicts in future.
+
+Add some full-stack integration tests that interact with the production Pusher environment.
+
+## 1.4.3
+
+Trigger pusher:connection\_failed if no websocket is defined, allowing the event to work on iphones etc.
+
+## 1.4.2
+
+ * Removed switch\_to\_secure and switch\_to\_unsecure in favour of automatic failover to ssl
+ * Generate internal events pusher:connection\_disconnected and pusher:connection\_failed
+ * Responds to pusher:connection\_established preparing for deprecation of connection\_established
+
+## 1.4.1
+
+Added switch\_to\_secure() and switch\_to\_unsecure() to enable ssl testing
+
+## 1.4
+
+Add ability to bind events to a specific channel:
+
+    var server = new Pusher("API_KEY", "my-channel")
+    server.channel("my-channel").bind("my-event", function(data) {
+      // do something
+    })
+
+## 1.3
+
+Add support for subscribing to private channels. Retrieves an authentication string via Ajax from your server - for more information view the docs: <http://pusherapp.com/docs/private_channels>
+
+## 1.2.1
+
+Basic support for subscribing to multiple channels:
+
+    var server = new Pusher("API_KEY", "my-channel")
+    server.subscribe("another-channel")
+    server.unsubscribe("my-channel")
+
+## 1.2
+
+Build a single Javascript file including all dependencies for Flash fallback and browsers that don't have a native JSON implementation.
+
+## 1
+
+First release!

+
+## Installation
+
+### Web
+
+If you're using Pusher Channels on a web page, you can install the library via:
+
+#### Encrypted Channel Support
+
+The encryption primitives required to power [encrypted
+channels](https://github.com/pusher/pusher-js#encrypted-channels) increase the
+bundle size quite significantly. In order to keep bundle sizes down, the
+default web and worker builds of pusher-js no longer support [encrypted
+channels](https://github.com/pusher/pusher-js#encrypted-channels).
+
+If you'd like to make use of encrypted-channels, you need to import the
+`with-encryption` builds as described below.
+
+#### Yarn (or NPM)
+
+You can use any NPM-compatible package manager, including NPM itself and Yarn.
+
+```bash
+yarn add pusher-js
+```
+
+Then:
+
+```javascript
+import Pusher from 'pusher-js';
+```
+
+If you'd like to use encrypted channels:
+
+```javascript
+import Pusher from 'pusher-js/with-encryption';
+```
+
+Or, if you're not using ES6 modules:
+
+```javascript
+const Pusher = require('pusher-js');
+```
+
+If you'd like to use encrypted channels:
+
+```javascript
+const Pusher = require('pusher-js/with-encryption');
+```
+
+#### CDN
+
+```html
+<script src="https://js.pusher.com/7.0/pusher.min.js"></script>
+```
+
+If you'd like to use encrypted channels:
+
+```html
+<script src="https://js.pusher.com/7.0/pusher-with-encryption.min.js"></script>
+```
+
+You can also use [cdnjs.com](https://cdnjs.com/libraries/pusher) if you prefer
+or as a fallback.
+
+#### Bower (discouraged)
+
+Or via [Bower](http://bower.io/):
+
+```bash
+bower install pusher
+```
+
+and then:
+
+```html
+<script src="bower_components/pusher/dist/web/pusher.min.js"></script>
+```
+
+### Typescript
+
+We've provided typescript declarations since v5.1.0. Most things should work
+out of the box but if you need access to specific types you can import them
+like so:
+
+```
+import Pusher from 'pusher-js';
+import * as PusherTypes from 'pusher-js';
+
+var presenceChannel: PusherTypes.PresenceChannel;
+...
+```
+
+### React Native
+
+> **⚠️ Important notice**
+>
+> React Native support has been **deprecated** and soon will be removed from this repository.
+>
+> Please, use our official [React Native SDK](https://github.com/pusher/pusher-websocket-react-native) instead.
+
+### Web Workers
+(`pusher-js`'s Web Workers implementation is currently not compatible with Internet Explorer)
+You can import the worker script (`pusher.worker.js`, not `pusher.js`) from the CDN:
+
+```javascript
+importScripts('https://js.pusher.com/7.0/pusher.worker.min.js');
+```
+
+If you'd like to use encrypted channels:
+
+```javascript
+importScripts('https://js.pusher.com/7.0/pusher-with-encryption.worker.min.js');
+```
+
+If you're building your worker with a bundler, you can import the worker entrypoint
+
+```
+import Pusher from 'pusher-js/worker'
+```
+
+If you'd like to use encrypted channels:
+
+```
+import Pusher from 'pusher-js/worker/with-encryption'
+```
+
+### Node.js
+
+Having installed `pusher-js` via an NPM-compatible package manager, run:
+
+```javascript
+import Pusher from 'pusher-js';
+```
+
+Notes:
+
+* For standard `WebWorkers`, this build will use HTTP as a fallback.
+* For `ServiceWorkers`, as the `XMLHttpRequest` API is unavailable, there is currently no support for HTTP fallbacks. However, we are open to requests for fallbacks using `fetch` if there is demand.
+
+## Initialization
+
+```js
+const pusher = new Pusher(APP_KEY, {
+  cluster: APP_CLUSTER,
+});
+```
+
+You can get your `APP_KEY` and `APP_CLUSTER` from the [Pusher Channels dashboard](https://dashboard.pusher.com/).
+
+## Configuration
+
+There are a number of configuration parameters which can be set for the client, which can be passed as an object to the Pusher constructor, i.e.:
+
+```js
+const pusher = new Pusher(APP_KEY, {
+  cluster: APP_CLUSTER,
+  channelAuthorization: {
+    endpoint: 'http://example.com/pusher/auth'
+  },
+});
+```
+
+For most users, there is little need to change these. See [client API guide](http://pusher.com/docs/client_api_guide/client_connect) for more details.
+
+#### `forceTLS` (Boolean)
+
+Forces the connection to use TLS. When set to `false` the library will attempt non-TLS connections first. Defaults to `true`.
+
+### `userAuthentication` (Object)
+
+Object containing the configuration for user authentication. Valid keys are:
+
+* `endpoint` (String) - Endpoint on your server that will return the authentication signature needed for signing the user in. Defaults to `/pusher/user-auth`.
+
+* `transport` (String) - Defines how the authentication endpoint will be called. There are two options available:
+  * `ajax` - the **default** option where an `XMLHttpRequest` object will be used to make a request. The parameters will be passed as `POST` parameters.
+  * `jsonp` - The authentication endpoint will be called by a `<script>` tag being dynamically created pointing to the endpoint defined by `userAuthentication.endpoint`. This can be used when the authentication endpoint is on a different domain to the web application. The endpoint will therefore be requested as a `GET` and parameters passed in the query string.
+
+* `params` (Object) - Additional parameters to be sent when the user authentication endpoint is called. When using ajax authentication the parameters are passed as additional POST parameters. When using jsonp authentication the parameters are passed as GET parameters. This can be useful with web application frameworks that guard against CSRF (Cross-site request forgery).
+
+* `headers` (Object) - Only applied when using `ajax` as authentication transport. Provides the ability to pass additional HTTP Headers to the user authentication endpoint. This can be useful with some web application frameworks that guard against CSRF CSRF (Cross-site request forgery).
+
+* `paramsProvider` (Function) - When present, this function is called to get additional parameters to be sent when the user authentication endpoint is called. This is equivalent to passing them on the params key, but allows for the parameters to be retrieved dynamically at the time of the request.
+
+* `headersProvider` (Function) - When present, this function is called to get additional headers to be sent when the user authentication endpoint is called. This is equivalent to passing them on the headers key, but allows for the headers to be retrieved dynamically at the time of the request.
+
+* `customHandler` (Function) - When present, this function is called instead of a request being made to the endpoint specified by `userAuthentication.endpoint`.
+
+
+For more information see [authenticating users](https://pusher.com/docs/channels/server_api/authenticating-users/).
+
+
+### `channelAuthorization` (Object)
+
+Object containing the configuration for user authorization. Valid keys are:
+
+* `endpoint` (String) - Endpoint on your server that will return the authorization signature needed for private and presence channels. Defaults to `/pusher/auth`.
+
+* `transport` (String) - Defines how the authorization endpoint will be called. There are two options available:
+  * `ajax` - the **default** option where an `XMLHttpRequest` object will be used to make a request. The parameters will be passed as `POST` parameters.
+  * `jsonp` - The authorization endpoint will be called by a `<script>` tag being dynamically created pointing to the endpoint defined by `channelAuthorization.endpoint`. This can be used when the authorization endpoint is on a different domain to the web application. The endpoint will therefore be requested as a `GET` and parameters passed in the query string.
+
+* `params` (Object) - Additional parameters to be sent when the channel authorization endpoint is called. When using ajax authorization the parameters are passed as additional POST parameters. When using jsonp authorization the parameters are passed as GET parameters. This can be useful with web application frameworks that guard against CSRF (Cross-site request forgery).
+
+* `headers` (Object) - Only applied when using `ajax` as authorizing transport. Provides the ability to pass additional HTTP Headers to the user authorization endpoint. This can be useful with some web application frameworks that guard against CSRF CSRF (Cross-site request forgery).
+
+* `paramsProvider` (Function) - When present, this function is called to get additional parameters to be sent when the user authentication endpoint is called. This is equivalent to passing them on the params key, but allows for the parameters to be retrieved dynamically at the time of the request.
+
+* `headersProvider` (Function) - When present, this function is called to get additional headers to be sent when the user authentication endpoint is called. This is equivalent to passing them on the headers key, but allows for the headers to be retrieved dynamically at the time of the request.
+
+* `customHandler` (Function) - When present, this function is called instead of a request being made to the endpoint specified by `channelAuthorization.endpoint`.
+
+
+For more information see [authorizing users](https://pusher.com/docs/channels/server_api/authorizing-users).
+
+
+#### `cluster` (String)
+
+Specifies the cluster that pusher-js should connect to. [If you'd like to see a full list of our clusters, click here](https://pusher.com/docs/clusters). If you do not specify a cluster, `mt1` will be used by default.
+
+```js
+const pusher = new Pusher(APP_KEY, {
+  cluster: APP_CLUSTER,
+});
+```
+
+#### `disableStats` (deprecated) (Boolean)
+
+Disables stats collection, so that connection metrics are not submitted to Pusher’s servers. These stats are used for internal monitoring only and they do not affect the account stats.
+*This option is deprecated since stats collection is now disabled by default*
+
+#### `enableStats` (Boolean)
+
+Enables stats collection, so that connection metrics are submitted to Pusher’s servers. These stats can help pusher engineers debug connection issues.
+
+#### `enabledTransports` (Array)
+
+Specifies which transports should be used by pusher-js to establish a connection. Useful for applications running in controlled, well-behaving environments. Available transports for web: `ws`, `wss`, `xhr_streaming`, `xhr_polling`, `sockjs`. If you specify your transports in this way, you may miss out on new transports we add in the future.
+
+```js
+// Only use WebSockets
+const pusher = new Pusher(APP_KEY, {
+  cluster: APP_CLUSTER,
+  enabledTransports: ['ws']
+});
+```
+
+Note: if you intend to use secure websockets, or `wss`, you can not simply specify `wss` in `enabledTransports`, you must specify `ws` in `enabledTransports` as well as set the `forceTLS` option to `true`.
+
+```js
+// Only use secure WebSockets
+const pusher = new Pusher(APP_KEY, {
+  cluster: APP_CLUSTER,
+  enabledTransports: ['ws'],
+  forceTLS: true
+});
+```
+
+#### `disabledTransports` (Array)
+
+Specifies which transports must not be used by pusher-js to establish a connection. This settings overwrites transports whitelisted via the `enabledTransports` options. Available transports for web: `ws`, `wss`, `xhr_streaming`, `xhr_polling`, `sockjs`. This is a whitelist, so any new transports we introduce in the future will be used until you explicitly add them to this list.
+
+```js
+// Use all transports except for sockjs
+const pusher = new Pusher(APP_KEY, {
+  cluster: APP_CLUSTER,
+  disabledTransports: ['sockjs']
+});
+
+// Only use WebSockets
+const pusher = new Pusher(APP_KEY, {
+  cluster: APP_CLUSTER,
+  enabledTransports: ['ws', 'xhr_streaming'],
+  disabledTransports: ['xhr_streaming']
+});
+```
+
+#### `wsHost`, `wsPort`, `wssPort`, `httpHost`, `httpPort`, `httpsPort`
+
+These can be changed to point to alternative Pusher Channels URLs (used internally for our staging server).
+
+#### `wsPath`
+
+Useful in special scenarios if you're using the library against an endpoint you control yourself. This is used internally for testing.
+
+#### `ignoreNullOrigin` (Boolean)
+
+Ignores null origin checks for HTTP fallbacks. Use with care, it should be disabled only if necessary (i.e. PhoneGap).
+
+#### `activityTimeout` (Integer)
+
+If there is no activity for this length of time (in milliseconds), the client will ping the server to check if the connection is still working. The default value is set by the server. Setting this value to be too low will result in unnecessary traffic.
+
+#### `pongTimeout` (Integer)
+
+Time before the connection is terminated after a ping is sent to the server. Default is 30000 (30s). Low values will cause false disconnections, if latency is high.
+
+## Global configuration
+
+### `Pusher.logToConsole` (Boolean)
+
+Enables logging to the browser console via calls to `console.log`.
+
+### `Pusher.log` (Function)
+
+Assign a custom log handler for the pusher-js library logging. For example:
+
+```js
+Pusher.log = (msg) => {
+  console.log(msg);
+};
+```
+
+By setting the `log` property you also override the use of `Pusher.enableLogging`.
+
+## Connection
+
+A connection to Pusher Channels is established by providing your `APP_KEY` and `APP_CLUSTER` to the constructor function:
+
+```js
+const pusher = new Pusher(APP_KEY, {
+  cluster: APP_CLUSTER,
+});
+```
+
+This returns a pusher object which can then be used to subscribe to channels.
+
+One reason this connection might fail is your account being over its' limits. You can detect this in the client by binding to the `error` event on the `pusher.connection` object. For example:
+
+```js
+const pusher = new Pusher('app_key', { cluster: APP_CLUSTER });
+pusher.connection.bind( 'error', function( err ) {
+  if( err.data.code === 4004 ) {
+    log('Over limit!');
+  }
+});
+```
+
+You may disconnect again by invoking the `disconnect` method:
+
+```js
+pusher.disconnect();
+```
+
+### Connection States
+The connection can be in any one of these states.
+
+**State**|**Note**
+--- | ---
+initialized|Initial state. No event is emitted in this state.
+connecting|All dependencies have been loaded and Channels is trying to connect. The connection will also enter this state when it is trying to reconnect after a connection failure.
+connected|The connection to Channels is open and authenticated with your app.
+unavailable|The connection is temporarily unavailable. In most cases this means that there is no internet connection. It could also mean that Channels is down
+failed|Channels is not supported by the browser. This implies that WebSockets are not natively available and an HTTP-based transport could not be found.
+disconnected|The Channels connection was previously connected and has now intentionally been closed.
+
+### Socket IDs
+
+Making a connection provides the client with a new `socket_id` that is assigned by the server. This can be used to distinguish the client's own events. A change of state might otherwise be duplicated in the client. More information on this pattern is available [here](http://pusherapp.com/docs/duplicates).
+
+It is also stored within the socket, and used as a token for generating signatures for private channels.
+
+## Subscribing to channels
+
+### Public channels
+
+The default method for subscribing to a channel involves invoking the `subscribe` method of your pusher object:
+
+```js
+const channel = pusher.subscribe('my-channel');
+```
+
+This returns a Channel object which events can be bound to.
+
+### Private channels
+
+Private channels are created in exactly the same way as normal channels, except that they reside in the 'private-' namespace. This means prefixing the channel name:
+
+```js
+const channel = pusher.subscribe('private-my-channel');
+```
+
+### Encrypted Channels
+
+Like private channels, encrypted channels have their own namespace, 'private-encrypted-'. For more information about encrypted channels, please see the [docs](https://pusher.com/docs/channels/using_channels/encrypted-channels).
+
+```js
+const channel = pusher.subscribe('private-encrypted-my-channel');
+```
+
+## Accessing Channels
+
+It is possible to access channels by name, through the `channel` function:
+
+```js
+const channel = pusher.channel('private-my-channel');
+```
+
+It is possible to access all subscribed channels through the `allChannels` function:
+
+```js
+pusher.allChannels().forEach(channel => console.log(channel.name));
+```
+
+Private, presence and encrypted channels will make a request to your `channelAuthorization.endpoint` (`/pusher/auth`) by default, where you will have to [authorize the subscription](https://pusher.com/docs/authorizing_users). You will have to send back the correct authorization response and a 200 status code.
+
+## Unsubscribing from channels
+
+To unsubscribe from a channel, invoke the `unsubscribe` method of your pusher object:
+
+```js
+pusher.unsubscribe('my-channel');
+```
+
+Unsubscribing from private channels is done in exactly the same way, just with the additional `private-` prefix:
+
+```js
+pusher.unsubscribe('private-my-channel');
+```
+
+## Binding to events
+
+Event binding takes a very similar form to the way events are handled in jQuery. You can use the following methods either on a channel object, to bind to events on a particular channel; or on the pusher object, to bind to events on all subscribed channels simultaneously.
+
+### `bind` and `unbind`
+Binding to "new-message" on channel: The following logs message data to the console when "new-message" is received
+```js
+channel.bind('new-message', function (data) {
+  console.log(data.message);
+});
+```
+
+We can also provide the `this` value when calling a handler as a third optional parameter. The following logs "hi Pusher" when "my-event" is fired.
+
+```js
+channel.bind('my-event', function () {
+  console.log(`hi ${this.name}`);
+}, { name: 'Pusher' });
+```
+
+For client-events on presence channels, bound callbacks will be called with an additional argument. This argument is an object containing the `user_id` of the user who triggered the event
+
+```
+presenceChannel.bind('client-message', function (data, metadata) {
+  console.log('received data from', metadata.user_id, ':', data);
+});
+```
+
+Unsubscribe behaviour varies depending on which parameters you provide it with. For example:
+
+```js
+// Remove just `handler` for the `new-comment` event
+channel.unbind('new-comment', handler);
+
+// Remove all handlers for the `new-comment` event
+channel.unbind('new-comment');
+
+// Remove `handler` for all events
+channel.unbind(null, handler);
+
+// Remove all handlers for `context`
+channel.unbind(null, null, context);
+
+// Remove all handlers on `channel`
+channel.unbind();
+```
+
+### `bind_global` and `unbind_global`
+
+`bind_global` and `unbind_global` work much like `bind` and `unbind`, but instead of only firing callbacks on a specific event, they fire callbacks on any event, and provide that event along to the handler along with the event data. For example:
+
+```js
+channel.bind_global(function (event, data) {
+  console.log(`The event ${event} was triggered with data ${data}`);
+})
+```
+
+`unbind_global` works similarly to `unbind`.
+
+```js
+// remove just `handler` from global bindings
+channel.unbind_global(handler);
+
+// remove all global bindings
+channel.unbind_global();
+```
+
+### `unbind_all`
+
+The `unbind_all` method is equivalent to calling `unbind()` and `unbind_global()` together; it removes all bindings, global and event specific.
+
+## Triggering Client Events
+
+It's possible to trigger [client events](https://pusher.com/docs/channels/using_channels/events#triggering-client-events) using the `trigger` method on an instance of the `Channel` class.
+
+A few gotchas to consider when using client events:
+- Client events can only be triggered on private/presence channels
+- Client events must be enabled in the settings page for your app: `https://dashboard.pusher.com/apps/$YOUR_APP_ID/settings`
+- The event name for client events *must* start with `client-`
+
+```
+channel.trigger('client-my-event', {message: 'Hello, world!'})
+```
+
+
+## Batching authorization requests (aka multi-authorization)
+
+Currently, pusher-js itself does not support authorizing multiple channels in one HTTP request. However, thanks to @dirkbonhomme you can use the [pusher-js-auth](https://github.com/dirkbonhomme/pusher-js-auth) plugin that buffers subscription requests and sends authorization requests to your endpoint in batches.
+
+## Default events
+
+There are a number of events which are used internally, but can also be of use elsewhere, for instance `subscribe`. There is also a `state_change` event - which fires whenever there is a state change. You can use it like this:
+
+```js
+pusher.connection.bind('state_change', function(states) {
+  // states = {previous: 'oldState', current: 'newState'}
+  $('div#status').text("Channels current state is " + states.current);
+});
+```
+
+## Connection Events
+
+To listen for when you connect to Pusher Channels:
+
+```js
+pusher.connection.bind('connected', callback);
+```
+
+And to bind to disconnections:
+
+```js
+pusher.connection.bind('disconnected', callback);
+```
+
+## Self-serving JS files
+
+You can host JavaScript files yourself, but it's a bit more complicated than putting them somewhere and just linking `pusher.js` in the source of your website. Because pusher-js loads fallback files dynamically, the dependency loader must be configured correctly or it will be using `js.pusher.com`.
+
+First, clone this repository and run `npm install && git submodule init && git submodule update`. Then run:
+
+    $ CDN_HTTP='http://your.http.url' CDN_HTTPS='https://your.https.url' make web
+
+In the `dist/web` folder, you should see the files you need: `pusher.js`, `pusher.min.js`, `json2.js`, `json.min.js`, `sockjs.js` and `sockjs.min.js`. `pusher.js` should be built referencing your URLs as the dependency hosts.
+
+First, make sure you expose all files from the `dist` directory. They need to be in a directory with named after the version number. For example, if you're hosting version 7.0.0 under `http://example.com/pusher-js` (and https for SSL), files should be accessible under following URL's:
+
+    http://example.com/pusher-js/7.0.0/pusher.js
+    http://example.com/pusher-js/7.0.0/json2.js
+    http://example.com/pusher-js/7.0.0/sockjs.js
+
+Minified files should have `.min` in their names, as in the `dist/web` directory:
+
+    http://example.com/pusher-js/7.0.0/pusher.min.js
+    http://example.com/pusher-js/7.0.0/json2.min.js
+    http://example.com/pusher-js/7.0.0/sockjs.min.js
+
+## SockJS compatibility
+
+Most browsers have a limit of 6 simultaneous connections to a single domain, but Internet Explorer 6 and 7 have a limit of just 2. This means that you can only use a single Pusher Channels connection in these browsers, because SockJS requires an HTTP connection for incoming data and another one for sending. Opening the second connection will break the first one as the client won't be able to respond to ping messages and get disconnected eventually.
+
+All other browsers work fine with two or three connections.
+
+## Developing
+
+Install all dependencies via Yarn:
+
+```bash
+yarn install
+```
+
+Run a development server which serves bundled javascript from <http://localhost:5555/pusher.js> so that you can edit files in /src freely.
+
+```bash
+make serve
+```
+
+You can optionally pass a `PORT` environment variable to run the server on a different port. You can also pass `CDN_HTTP` and `CDN_HTTPS` variables if you wish the library to load dependencies from a new host.
+
+This command will serve `pusher.js`, `sockjs.js`, `json2.js`, and their respective minified versions.
+
+### Core Vs. Platform-Specific Code
+
+New to pusher-js 3.1 is the ability for the library to produce builds for different runtimes: classic web, NodeJS and
+Web Workers.
+
+In order for this to happen, we have split the library into two directories: `core/` and `runtimes/`. In `core` we keep anything that is platform-independent. In `runtimes` we keep code that depends on certain runtimes.
+
+Throughout the `core/` directory you'll find this line:
+
+```javascript
+import Runtime from "runtime";
+```
+
+We use webpack module resolution to make the library look for different versions of this module depending on the build.
+
+For web it will look for `src/runtimes/web/runtime.ts`. For ReactNative, `src/runtimes/react-native/runtime.ts`. For Node:  `src/runtimes/node/runtime.ts`. For worker: `src/runtimes/worker/runtime.ts`.
+
+Each of these runtime files exports an object (conforming to the interface you can see in `src/runtimes/interface.ts`) that abstracts away everything platform-specific. The core library pulls this object in without any knowledge of how it implements it. This means web build can use the DOM underneath, the ReactNative build can use its native NetInfo API, Workers can use `fetch` and so on.
+
+### Building
+
+In order to build SockJS, you must first initialize and update the Git submodule:
+
+```bash
+git submodule init
+git submodule update
+```
+
+Then run:
+
+```bash
+make web
+```
+
+This will build the source files relevant for the web build into `dist/web`.
+
+In order to specify the library version, you can either update `package.json` or pass a `VERSION` environment variable upon building.
+
+Other build commands include:
+
+```bash
+make node         # for the NodeJS build
+make worker       # for the worker build
+```
+
+### Testing
+
+Each test environment contains two types of tests:
+
+1. unit tests,
+2. integration tests.
+
+Unit tests are simple, fast and don't need any external dependencies. Integration tests usually connect to production and js-integration-api servers and can use a local server for loading JS files, so they need an Internet connection to work.
+
+There are 3 different testing environments: one for web, one for NodeJS and one for workers.
+
+The web and worker tests use [Karma](https://github.com/karma-runner/karma) to execute specs in real browsers. The NodeJS tests use [jasmine-node](https://github.com/mhevery/jasmine-node).
+
+To run the tests:
+
+```bash
+# For web
+make web_unit
+make web_integration
+
+# For NodeJS
+make node_unit
+make node_integration
+
+# For workers
+make worker_unit
+make worker_integration
+```
+
+If you want your Karma tests to automatically reload, then in `spec/karma/config.common.js` set `singleRun` to `false`.

+Streams in a WebSocket connection
+---------------------------------

+
+Message transfer in each direction is simple: IO receives a byte stream [1] and
+sends this stream for parsing. The parser will periodically emit a complete
+message text on the Messages stream [2]. Similarly, when messages are written
+to the Messages stream [3], they are framed using the WebSocket wire format and
+emitted via IO [4].
+
+There is a feedback loop via [5] since some input from [1] will be things like
+ping, pong and close frames. In these cases the protocol responds by emitting
+responses directly back to [4] rather than emitting messages via [2].
+
+For the purposes of flow control, we consider the sources of each Readable
+stream to be as follows:
+
+* [2] receives input from [1]
+* [4] receives input from [1] and [3]
+
+The classes below express the relationships described above without prescribing
+anything about how parse() and frame() work, other than assuming they emit
+'data' events to the IO and Messages streams. They will work with any protocol
+driver having these two methods.

+
+
+    This file creates a global JSON object containing two methods: stringify
+    and parse.
+
+        JSON.stringify(value, replacer, space)
+            value       any JavaScript value, usually an object or array.
+
+            replacer    an optional parameter that determines how object
+                        values are stringified for objects. It can be a
+                        function or an array of strings.
+
+            space       an optional parameter that specifies the indentation
+                        of nested structures. If it is omitted, the text will
+                        be packed without extra whitespace. If it is a number,
+                        it will specify the number of spaces to indent at each
+                        level. If it is a string (such as '\t' or '&nbsp;'),
+                        it contains the characters used to indent at each level.
+
+            This method produces a JSON text from a JavaScript value.
+
+            When an object value is found, if the object contains a toJSON
+            method, its toJSON method will be called and the result will be
+            stringified. A toJSON method does not serialize: it returns the
+            value represented by the name/value pair that should be serialized,
+            or undefined if nothing should be serialized. The toJSON method
+            will be passed the key associated with the value, and this will be
+            bound to the value
+
+            For example, this would serialize Dates as ISO strings.
+
+                Date.prototype.toJSON = function (key) {
+                    function f(n) {
+                        // Format integers to have at least two digits.
+                        return n < 10 ? '0' + n : n;
+                    }
+
+                    return this.getUTCFullYear()   + '-' +
+                         f(this.getUTCMonth() + 1) + '-' +
+                         f(this.getUTCDate())      + 'T' +
+                         f(this.getUTCHours())     + ':' +
+                         f(this.getUTCMinutes())   + ':' +
+                         f(this.getUTCSeconds())   + 'Z';
+                };
+
+            You can provide an optional replacer method. It will be passed the
+            key and value of each member, with this bound to the containing
+            object. The value that is returned from your method will be
+            serialized. If your method returns undefined, then the member will
+            be excluded from the serialization.
+
+            If the replacer parameter is an array of strings, then it will be
+            used to select the members to be serialized. It filters the results
+            such that only members with keys listed in the replacer array are
+            stringified.
+
+            Values that do not have JSON representations, such as undefined or
+            functions, will not be serialized. Such values in objects will be
+            dropped; in arrays they will be replaced with null. You can use
+            a replacer function to replace those with JSON values.
+            JSON.stringify(undefined) returns undefined.
+
+            The optional space parameter produces a stringification of the
+            value that is filled with line breaks and indentation to make it
+            easier to read.
+
+            If the space parameter is a non-empty string, then that string will
+            be used for indentation. If the space parameter is a number, then
+            the indentation will be that many spaces.
+
+            Example:
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}]);
+            // text is '["e",{"pluribus":"unum"}]'
+
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
+            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
+
+            text = JSON.stringify([new Date()], function (key, value) {
+                return this[key] instanceof Date ?
+                    'Date(' + this[key] + ')' : value;
+            });
+            // text is '["Date(---current time---)"]'
+
+
+        JSON.parse(text, reviver)
+            This method parses a JSON text to produce an object or array.
+            It can throw a SyntaxError exception.
+
+            The optional reviver parameter is a function that can filter and
+            transform the results. It receives each of the keys and values,
+            and its return value is used instead of the original value.
+            If it returns what it received, then the structure is not modified.
+            If it returns undefined then the member is deleted.
+
+            Example:
+
+            // Parse the text. Values that look like ISO date strings will
+            // be converted to Date objects.
+
+            myData = JSON.parse(text, function (key, value) {
+                var a;
+                if (typeof value === 'string') {
+                    a =
+/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
+                    if (a) {
+                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+                            +a[5], +a[6]));
+                    }
+                }
+                return value;
+            });
+
+            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
+                var d;
+                if (typeof value === 'string' &&
+                        value.slice(0, 5) === 'Date(' &&
+                        value.slice(-1) === ')') {
+                    d = new Date(value.slice(5, -1));
+                    if (d) {

+# core with runtime
+
+This directory contains unit tests for core features that requires access to a `Runtime`. These tests will be included in the unit tests for each runtime and the proper runtime will be loaded before calling those tests.
+
+In order for this to work, this directory `core_with_runtime` need to be included in `unit/index.node.js` and similar files after the proper runtime directory is included (ex. `unit/node`)

+
+
+    This file creates a global JSON object containing two methods: stringify
+    and parse.
+
+        JSON.stringify(value, replacer, space)
+            value       any JavaScript value, usually an object or array.
+
+            replacer    an optional parameter that determines how object
+                        values are stringified for objects. It can be a
+                        function or an array of strings.
+
+            space       an optional parameter that specifies the indentation
+                        of nested structures. If it is omitted, the text will
+                        be packed without extra whitespace. If it is a number,
+                        it will specify the number of spaces to indent at each
+                        level. If it is a string (such as '\t' or '&nbsp;'),
+                        it contains the characters used to indent at each level.
+
+            This method produces a JSON text from a JavaScript value.
+
+            When an object value is found, if the object contains a toJSON
+            method, its toJSON method will be called and the result will be
+            stringified. A toJSON method does not serialize: it returns the
+            value represented by the name/value pair that should be serialized,
+            or undefined if nothing should be serialized. The toJSON method
+            will be passed the key associated with the value, and this will be
+            bound to the value
+
+            For example, this would serialize Dates as ISO strings.
+
+                Date.prototype.toJSON = function (key) {
+                    function f(n) {
+                        // Format integers to have at least two digits.
+                        return n < 10 ? '0' + n : n;
+                    }
+
+                    return this.getUTCFullYear()   + '-' +
+                         f(this.getUTCMonth() + 1) + '-' +
+                         f(this.getUTCDate())      + 'T' +
+                         f(this.getUTCHours())     + ':' +
+                         f(this.getUTCMinutes())   + ':' +
+                         f(this.getUTCSeconds())   + 'Z';
+                };
+
+            You can provide an optional replacer method. It will be passed the
+            key and value of each member, with this bound to the containing
+            object. The value that is returned from your method will be
+            serialized. If your method returns undefined, then the member will
+            be excluded from the serialization.
+
+            If the replacer parameter is an array of strings, then it will be
+            used to select the members to be serialized. It filters the results
+            such that only members with keys listed in the replacer array are
+            stringified.
+
+            Values that do not have JSON representations, such as undefined or
+            functions, will not be serialized. Such values in objects will be
+            dropped; in arrays they will be replaced with null. You can use
+            a replacer function to replace those with JSON values.
+            JSON.stringify(undefined) returns undefined.
+
+            The optional space parameter produces a stringification of the
+            value that is filled with line breaks and indentation to make it
+            easier to read.
+
+            If the space parameter is a non-empty string, then that string will
+            be used for indentation. If the space parameter is a number, then
+            the indentation will be that many spaces.
+
+            Example:
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}]);
+            // text is '["e",{"pluribus":"unum"}]'
+
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
+            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
+
+            text = JSON.stringify([new Date()], function (key, value) {
+                return this[key] instanceof Date ?
+                    'Date(' + this[key] + ')' : value;
+            });
+            // text is '["Date(---current time---)"]'
+
+
+        JSON.parse(text, reviver)
+            This method parses a JSON text to produce an object or array.
+            It can throw a SyntaxError exception.
+
+            The optional reviver parameter is a function that can filter and
+            transform the results. It receives each of the keys and values,
+            and its return value is used instead of the original value.
+            If it returns what it received, then the structure is not modified.
+            If it returns undefined then the member is deleted.
+
+            Example:
+
+            // Parse the text. Values that look like ISO date strings will
+            // be converted to Date objects.
+
+            myData = JSON.parse(text, function (key, value) {
+                var a;
+                if (typeof value === 'string') {
+                    a =
+/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
+                    if (a) {
+                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+                            +a[5], +a[6]));
+                    }
+                }
+                return value;
+            });
+
+            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
+                var d;
+                if (typeof value === 'string' &&
+                        value.slice(0, 5) === 'Date(' &&

+<h1 align="center">Rollup</h1>
+
+## Overview
+
+Rollup is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. It uses the standardized ES module format for code, instead of previous idiosyncratic solutions such as CommonJS and AMD. ES modules let you freely and seamlessly combine the most useful individual functions from your favorite libraries. Rollup can optimize ES modules for faster native loading in modern browsers, or output a legacy module format allowing ES module workflows today.
+
+## Quick Start Guide
+
+Install with `npm install --global rollup`. Rollup can be used either through a [command line interface](https://rollupjs.org/command-line-interface/) with an optional configuration file or else through its [JavaScript API](https://rollupjs.org/javascript-api/). Run `rollup --help` to see the available options and parameters. The starter project templates, [rollup-starter-lib](https://github.com/rollup/rollup-starter-lib) and [rollup-starter-app](https://github.com/rollup/rollup-starter-app), demonstrate common configuration options, and more detailed instructions are available throughout the [user guide](https://rollupjs.org/introduction/).
+
+### Commands
+
+These commands assume the entry point to your application is named main.js, and that you'd like all imports compiled into a single file named bundle.js.
+
+For browsers:
+
+```bash
+# compile to a <script> containing a self-executing function
+rollup main.js --format iife --name "myBundle" --file bundle.js
+```
+
+For Node.js:
+
+```bash
+# compile to a CommonJS module
+rollup main.js --format cjs --file bundle.js
+```
+
+For both browsers and Node.js:
+
+```bash
+# UMD format requires a bundle name
+rollup main.js --format umd --name "myBundle" --file bundle.js
+```
+
+## Why
+
+Developing software is usually easier if you break your project into smaller separate pieces, since that often removes unexpected interactions and dramatically reduces the complexity of the problems you'll need to solve, and simply writing smaller projects in the first place [isn't necessarily the answer](https://medium.com/@Rich_Harris/small-modules-it-s-not-quite-that-simple-3ca532d65de4). Unfortunately, JavaScript has not historically included this capability as a core feature in the language.
+
+This finally changed with ES modules support in JavaScript, which provides a syntax for importing and exporting functions and data so they can be shared between separate scripts. Most browsers and Node.js support ES modules. However, Node.js releases before 12.17 support ES modules only behind the `--experimental-modules` flag, and older browsers like Internet Explorer do not support ES modules at all. Rollup allows you to write your code using ES modules, and run your application even in environments that do not support ES modules natively. For environments that support them, Rollup can output optimized ES modules; for environments that don't, Rollup can compile your code to other formats such as CommonJS modules, AMD modules, and IIFE-style scripts. This means that you get to _write future-proof code_, and you also get the tremendous benefits of...
+
+## Tree Shaking
+
+In addition to enabling the use of ES modules, Rollup also statically analyzes and optimizes the code you are importing, and will exclude anything that isn't actually used. This allows you to build on top of existing tools and modules without adding extra dependencies or bloating the size of your project.
+
+For example, with CommonJS, the _entire tool or library must be imported_.
+
+```js
+// import the entire utils object with CommonJS
+var utils = require('node:utils');
+var query = 'Rollup';
+// use the ajax method of the utils object
+utils.ajax('https://api.example.com?search=' + query).then(handleResponse);
+```
+
+But with ES modules, instead of importing the whole `utils` object, we can just import the one `ajax` function we need:
+
+```js
+// import the ajax function with an ES import statement
+import { ajax } from 'node:utils';
+var query = 'Rollup';
+// call the ajax function
+ajax('https://api.example.com?search=' + query).then(handleResponse);
+```
+
+Because Rollup includes the bare minimum, it results in lighter, faster, and less complicated libraries and applications. Since this approach is based on explicit `import` and `export` statements, it is vastly more effective than simply running an automated minifier to detect unused variables in the compiled output code.
+
+## Compatibility
+
+### Importing CommonJS
+
+Rollup can import existing CommonJS modules [through a plugin](https://github.com/rollup/plugins/tree/master/packages/commonjs).
+
+### Publishing ES Modules
+
+To make sure your ES modules are immediately usable by tools that work with CommonJS such as Node.js and webpack, you can use Rollup to compile to UMD or CommonJS format, and then point to that compiled version with the `main` property in your `package.json` file. If your `package.json` file also has a `module` field, ES-module-aware tools like Rollup and [webpack](https://webpack.js.org/) will [import the ES module version](https://github.com/rollup/rollup/wiki/pkg.module) directly.

+/**
+ * At its core, the algorithm first starts from each static or dynamic entry
+ * point and then assigns that entry point to all modules than can be reached
+ * via static imports. We call this the *dependent entry points* of that
+ * module.
+ *
+ * Then we group all modules with the same dependent entry points into chunks
+ * as those modules will always be loaded together.
+ *
+ * One non-trivial optimization we can apply is that dynamic entries are
+ * different from static entries in so far as when a dynamic import occurs,
+ * some
+ * modules are already in memory. If some of these modules are also
+ * dependencies
+ * of the dynamic entry, then it does not make sense to create a separate chunk
+ * for them. Instead, the dynamic import target can load them from the
+ * importing
+ * chunk.
+ *
+ * With regard to chunking, if B is implicitly loaded after A, then this can be
+ * handled the same way as if there was a dynamic import A => B.
+ *
+ * Example:
+ * Assume A -> B (A imports B), A => C (A dynamically imports C) and C -> B.
+ * Then the initial algorithm would assign A into the A chunk, C into the C
+ * chunk and B into the AC chunk, i.e. the chunk with the dependent entry
+ * points
+ * A and C.
+ * However we know that C can only be loaded from A, so A and its dependency B
+ * must already be in memory when C is loaded. So it is enough to create only
+ * two chunks A containing [AB] and C containing [C].
+ *
+ * So we do not assign the dynamic entry C as dependent entry point to modules
+ * that are already loaded.
+ *
+ * In a more complex example, let us assume that we have entry points X and Y.
+ * Further, let us assume
+ * X -> A, X -> B, X -> C,
+ * Y -> A, Y -> B,
+ * A => D,
+ * D -> B, D -> C
+ * So without dynamic import optimization, the dependent entry points are
+ * A: XY, B: DXY, C: DX, D: D, X: X, Y: Y,
+ * so we would for now create six chunks.
+ *
+ * Now D is loaded only after A is loaded. But A is loaded if either X is
+ * loaded
+ * or Y is loaded. So the modules that are already in memory when D is loaded
+ * are the intersection of all modules that X depends on with all modules that
+ * Y
+ * depends on, which in this case are the modules A and B.
+ * We could also say they are all modules that have both X and Y as dependent
+ * entry points.
+ *
+ * So we can remove D as dependent entry point from A and B, which means they
+ * both now have only XY as dependent entry points and can be merged into the
+ * same chunk.
+ *
+ * Now let us extend this to the most general case where we have several
+ * dynamic
+ * importers for one dynamic entry point.
+ *
+ * In the most general form, it works like this:
+ * For each dynamic entry point, we have a number of dynamic importers, which
+ * are the modules importing it. Using the previous ideas, we can determine
+ * the modules already in memory for each dynamic importer by looking for all
+ * modules that have all the dependent entry points of the dynamic importer as
+ * dependent entry points.
+ * So the modules that are guaranteed to be in memory when the dynamic entry
+ * point is loaded are the intersection of the modules already in memory for
+ * each dynamic importer.
+ *
+ * Assuming that A => D and B => D and A has dependent entry points XY and B
+ * has
+ * dependent entry points YZ, then the modules guaranteed to be in memory are
+ * all modules that have at least XYZ as dependent entry points.
+ * We call XYZ the *dynamically dependent entry points* of D.
+ *
+ * Now there is one last case to consider: If one of the dynamically dependent
+ * entries is itself a dynamic entry, then any module is in memory that either
+ * is a dependency of that dynamic entry or again has the dynamic dependent
+ * entries of that dynamic entry as dependent entry points.
+ *
+ * A naive algorithm for this proved to be costly as it contained an O(n^3)
+ * complexity with regard to dynamic entries that blew up for very large
+ * projects.
+ *
+ * If we have an efficient way to do Set operations, an alternative approach
+ * would be to instead collect already loaded modules per dynamic entry. And as
+ * all chunks from the initial grouping would behave the same, we can instead
+ * collect already loaded chunks for a performance improvement.
+ *
+ * To do that efficiently, need
+ * - a Map of dynamic imports per dynamic entry, which contains all dynamic
+ *   imports that can be triggered by a dynamic entry
+ * - a Map of static dependencies per entry
+ * - a Map of already loaded chunks per entry that we initially populate with
+ *   empty Sets for static entries and Sets containing all entries for dynamic
+ *   entries
+ *
+ * For efficient operations, we assign each entry a numerical index and
+ * represent Sets of Chunks as BigInt values where each chunk corresponds to a
+ * bit index. Then thw last two maps can be represented as arrays of BigInt
+ * values.
+ *
+ * Then we iterate through each dynamic entry. We set the already loaded modules
+ * to the intersection of the previously already loaded modules with the union
+ * of the already loaded modules of that chunk with its static dependencies.
+ *
+ * If the already loaded modules changed, then we use the Map of dynamic imports
+ * per dynamic entry to marks all dynamic entry dependencies as "dirty" and put
+ * them back into the iteration. As an additional optimization, we note for
+ * each dynamic entry which dynamic dependent entries have changed and only
+ * intersect those entries again on subsequent interations.
+ *
+ * Then we remove the dynamic entries from the list of dependent entries for
+ * those chunks that are already loaded for that dynamic entry and create
+ * another round of chunks.

+ * matter here, and we just discern chunks without side effects (pure chunks)
+ * from other chunks.
+ *
+ * As a first step, we assign each pre-generated chunk with side effects a
+ * label. I.e. we have side effect "A" if the non-pure chunk "A" is loaded.
+ *
+ * Now to determine the side effects of loading a chunk, one also has to take
+ * the side effects of its dependencies into account. So if A depends on B
+ * (A -> B) and both have side effects, loading A triggers effects AB.
+ *
+ * Now from the previous step we know that each chunk is uniquely determine by
+ * the entry points that depend on it and cause it to load, which we will call
+ * its dependent entry points.
+ *
+ * E.g. if X -> A and Y -> A, then the dependent entry points of A are XY.
+ * Starting from that idea, we can determine a set of chunks—and thus a set
+ * of side effects—that must have been triggered if a certain chunk has been
+ * loaded. Basically, it is the intersection of all chunks loaded by the
+ * dependent entry points of a given chunk. We call the corresponding side
+ * effects the correlated side effects of that chunk.
+ *
+ * Example:
+ * X -> ABC, Y -> ADE, A-> F, B -> D
+ * Then taking dependencies into account, X -> ABCDF, Y -> ADEF
+ * The intersection is ADF. So we know that when A is loaded, D and F must also
+ * be in memory even though neither D nor A is a dependency of the other.
+ * If all have side effects, we call ADF the correlated side effects of A. The
+ * correlated side effects need to remain constant when merging chunks.
+ *
+ * In contrast, we have the dependency side effects of A, which represents
+ * the side effects we trigger if we directly load A. In this example, the
+ * dependency side effects are AF.
+ * For entry chunks, dependency and correlated side effects are the same.
+ *
+ * With these concepts, merging chunks is allowed if the correlated side
+ * effects of each entry do not change. Thus, we are allowed to merge two
+ * chunks if
+ *
+ * a) the dependency side effects of each chunk are a subset of the correlated
+ *    side effects of the other chunk, so no additional side effects are
+ *    triggered for any entry, or
+ * b) The dependent entry points of chunk A are a subset of the dependent entry
+ *    points of chunk B while the dependency side effects of A are a subset of
+ *    the correlated side effects of B. Because in that scenario, whenever A is
+ *    loaded, B is loaded as well. But there are cases when B is loaded where A
+ *    is not loaded. So if we merge the chunks, all dependency side effects of
+ *    A will be added to the correlated side effects of B, and as the latter is
+ *    not allowed to change, the former need to be a subset of the latter.
+ *
+ * Another consideration when merging small chunks into other chunks is to
+ * avoid
+ * that too much additional code is loaded. This is achieved when the dependent
+ * entries of the small chunk are a subset of the dependent entries of the
+ * other
+ * chunk. Because then when the small chunk is loaded, the other chunk was
+ * loaded/in memory anyway, so at most when the other chunk is loaded, the
+ * additional size of the small chunk is loaded unnecessarily.
+ *
+ * So the algorithm performs merges in two passes:
+ *
+ * 1. First we try to merge small chunks A only into other chunks B if the
+ *    dependent entries of A are a subset of the dependent entries of B and the
+ *    dependency side effects of A are a subset of the correlated side effects
+ *    of B.
+ * 2. Only then for all remaining small chunks, we look for arbitrary merges
+ *    following the rule (a), starting with the smallest chunks to look for
+ *    possible merge targets.

+// - checkLValSimple() shall be used if the syntactic construct supports

+//
+//   > It is a Syntax Error if AssignmentTargetType of [the production] is not
+//   > simple.
+//
+//   It is also appropriate for checking if an identifier is valid and not
+//   defined elsewhere, like import declarations or function/class identifiers.
+//
+//   Examples where this is used include:
+//     a += …;
+//     import a from '…';
+//   where a is the node to be checked.
+//
+// - checkLValPattern() shall be used if the syntactic construct supports
+//   anything checkLValSimple() supports, as well as object and array
+//   destructuring patterns. This is generally appropriate for constructs for
+//   which the spec says
+//
+//   > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
+//   > an ArrayLiteral and AssignmentTargetType of [the production] is not
+//   > simple.
+//
+//   Examples where this is used include:
+//     (a = …);
+//     const a = …;
+//     try { … } catch (a) { … }
+//   where a is the node to be checked.
+//
+// - checkLValInnerPattern() shall be used if the syntactic construct supports
+//   anything checkLValPattern() supports, as well as default assignment
+//   patterns, rest elements, and other constructs that may appear within an
+//   object or array destructuring pattern.
+//
+//   As a special case, function parameters also use checkLValInnerPattern(),

+// an assignment, then bindingType should be set to BIND_NONE. Otherwise, it
+// should be set to the appropriate BIND_* constant, like BIND_VAR or
+// BIND_LEXICAL.
+//
+// If the function is called with a non-BIND_NONE bindingType, then

+ * At its core, the algorithm first starts from each static or dynamic entry
+ * point and then assigns that entry point to all modules than can be reached
+ * via static imports. We call this the *dependent entry points* of that
+ * module.
+ *
+ * Then we group all modules with the same dependent entry points into chunks
+ * as those modules will always be loaded together.
+ *
+ * One non-trivial optimization we can apply is that dynamic entries are
+ * different from static entries in so far as when a dynamic import occurs,
+ * some
+ * modules are already in memory. If some of these modules are also
+ * dependencies
+ * of the dynamic entry, then it does not make sense to create a separate chunk
+ * for them. Instead, the dynamic import target can load them from the
+ * importing
+ * chunk.
+ *
+ * With regard to chunking, if B is implicitly loaded after A, then this can be
+ * handled the same way as if there was a dynamic import A => B.
+ *
+ * Example:
+ * Assume A -> B (A imports B), A => C (A dynamically imports C) and C -> B.
+ * Then the initial algorithm would assign A into the A chunk, C into the C
+ * chunk and B into the AC chunk, i.e. the chunk with the dependent entry
+ * points
+ * A and C.
+ * However we know that C can only be loaded from A, so A and its dependency B
+ * must already be in memory when C is loaded. So it is enough to create only
+ * two chunks A containing [AB] and C containing [C].
+ *
+ * So we do not assign the dynamic entry C as dependent entry point to modules
+ * that are already loaded.
+ *
+ * In a more complex example, let us assume that we have entry points X and Y.
+ * Further, let us assume
+ * X -> A, X -> B, X -> C,
+ * Y -> A, Y -> B,
+ * A => D,
+ * D -> B, D -> C
+ * So without dynamic import optimization, the dependent entry points are
+ * A: XY, B: DXY, C: DX, D: D, X: X, Y: Y,
+ * so we would for now create six chunks.
+ *
+ * Now D is loaded only after A is loaded. But A is loaded if either X is
+ * loaded
+ * or Y is loaded. So the modules that are already in memory when D is loaded
+ * are the intersection of all modules that X depends on with all modules that
+ * Y
+ * depends on, which in this case are the modules A and B.
+ * We could also say they are all modules that have both X and Y as dependent
+ * entry points.
+ *
+ * So we can remove D as dependent entry point from A and B, which means they
+ * both now have only XY as dependent entry points and can be merged into the
+ * same chunk.
+ *
+ * Now let us extend this to the most general case where we have several
+ * dynamic
+ * importers for one dynamic entry point.
+ *
+ * In the most general form, it works like this:
+ * For each dynamic entry point, we have a number of dynamic importers, which
+ * are the modules importing it. Using the previous ideas, we can determine
+ * the modules already in memory for each dynamic importer by looking for all
+ * modules that have all the dependent entry points of the dynamic importer as
+ * dependent entry points.
+ * So the modules that are guaranteed to be in memory when the dynamic entry
+ * point is loaded are the intersection of the modules already in memory for
+ * each dynamic importer.
+ *
+ * Assuming that A => D and B => D and A has dependent entry points XY and B
+ * has
+ * dependent entry points YZ, then the modules guaranteed to be in memory are
+ * all modules that have at least XYZ as dependent entry points.
+ * We call XYZ the *dynamically dependent entry points* of D.
+ *
+ * Now there is one last case to consider: If one of the dynamically dependent
+ * entries is itself a dynamic entry, then any module is in memory that either
+ * is a dependency of that dynamic entry or again has the dynamic dependent
+ * entries of that dynamic entry as dependent entry points.
+ *
+ * A naive algorithm for this proved to be costly as it contained an O(n^3)
+ * complexity with regard to dynamic entries that blew up for very large
+ * projects.
+ *
+ * If we have an efficient way to do Set operations, an alternative approach
+ * would be to instead collect already loaded modules per dynamic entry. And as
+ * all chunks from the initial grouping would behave the same, we can instead
+ * collect already loaded chunks for a performance improvement.
+ *
+ * To do that efficiently, need
+ * - a Map of dynamic imports per dynamic entry, which contains all dynamic
+ *   imports that can be triggered by a dynamic entry
+ * - a Map of static dependencies per entry
+ * - a Map of already loaded chunks per entry that we initially populate with
+ *   empty Sets for static entries and Sets containing all entries for dynamic
+ *   entries
+ *
+ * For efficient operations, we assign each entry a numerical index and
+ * represent Sets of Chunks as BigInt values where each chunk corresponds to a
+ * bit index. Then thw last two maps can be represented as arrays of BigInt
+ * values.
+ *
+ * Then we iterate through each dynamic entry. We set the already loaded modules
+ * to the intersection of the previously already loaded modules with the union
+ * of the already loaded modules of that chunk with its static dependencies.
+ *
+ * If the already loaded modules changed, then we use the Map of dynamic imports
+ * per dynamic entry to marks all dynamic entry dependencies as "dirty" and put
+ * them back into the iteration. As an additional optimization, we note for
+ * each dynamic entry which dynamic dependent entries have changed and only
+ * intersect those entries again on subsequent interations.
+ *
+ * Then we remove the dynamic entries from the list of dependent entries for
+ * those chunks that are already loaded for that dynamic entry and create
+ * another round of chunks.

+/**
+ * This function tries to get rid of small chunks by merging them with other
+ * chunks.
+ *
+ * We can only merge chunks safely if after the merge, loading any entry point
+ * in any allowed order will not trigger side effects that should not have been
+ * triggered. While side effects are usually things like global function calls,
+ * global variable mutations or potentially thrown errors, details do not
+ * matter here, and we just discern chunks without side effects (pure chunks)
+ * from other chunks.
+ *
+ * As a first step, we assign each pre-generated chunk with side effects a
+ * label. I.e. we have side effect "A" if the non-pure chunk "A" is loaded.
+ *
+ * Now to determine the side effects of loading a chunk, one also has to take
+ * the side effects of its dependencies into account. So if A depends on B
+ * (A -> B) and both have side effects, loading A triggers effects AB.
+ *
+ * Now from the previous step we know that each chunk is uniquely determine by
+ * the entry points that depend on it and cause it to load, which we will call
+ * its dependent entry points.
+ *
+ * E.g. if X -> A and Y -> A, then the dependent entry points of A are XY.
+ * Starting from that idea, we can determine a set of chunks—and thus a set
+ * of side effects—that must have been triggered if a certain chunk has been
+ * loaded. Basically, it is the intersection of all chunks loaded by the
+ * dependent entry points of a given chunk. We call the corresponding side
+ * effects the correlated side effects of that chunk.
+ *
+ * Example:
+ * X -> ABC, Y -> ADE, A-> F, B -> D
+ * Then taking dependencies into account, X -> ABCDF, Y -> ADEF
+ * The intersection is ADF. So we know that when A is loaded, D and F must also
+ * be in memory even though neither D nor A is a dependency of the other.
+ * If all have side effects, we call ADF the correlated side effects of A. The
+ * correlated side effects need to remain constant when merging chunks.
+ *
+ * In contrast, we have the dependency side effects of A, which represents
+ * the side effects we trigger if we directly load A. In this example, the
+ * dependency side effects are AF.
+ * For entry chunks, dependency and correlated side effects are the same.
+ *
+ * With these concepts, merging chunks is allowed if the correlated side
+ * effects of each entry do not change. Thus, we are allowed to merge two
+ * chunks if
+ *
+ * a) the dependency side effects of each chunk are a subset of the correlated
+ *    side effects of the other chunk, so no additional side effects are
+ *    triggered for any entry, or
+ * b) The dependent entry points of chunk A are a subset of the dependent entry
+ *    points of chunk B while the dependency side effects of A are a subset of
+ *    the correlated side effects of B. Because in that scenario, whenever A is
+ *    loaded, B is loaded as well. But there are cases when B is loaded where A
+ *    is not loaded. So if we merge the chunks, all dependency side effects of
+ *    A will be added to the correlated side effects of B, and as the latter is
+ *    not allowed to change, the former need to be a subset of the latter.
+ *
+ * Another consideration when merging small chunks into other chunks is to
+ * avoid
+ * that too much additional code is loaded. This is achieved when the dependent
+ * entries of the small chunk are a subset of the dependent entries of the
+ * other
+ * chunk. Because then when the small chunk is loaded, the other chunk was
+ * loaded/in memory anyway, so at most when the other chunk is loaded, the
+ * additional size of the small chunk is loaded unnecessarily.
+ *
+ * So the algorithm performs merges in two passes:
+ *
+ * 1. First we try to merge small chunks A only into other chunks B if the
+ *    dependent entries of A are a subset of the dependent entries of B and the
+ *    dependency side effects of A are a subset of the correlated side effects
+ *    of B.
+ * 2. Only then for all remaining small chunks, we look for arbitrary merges
+ *    following the rule (a), starting with the smallest chunks to look for
+ *    possible merge targets.

+// The following three functions all verify that a node is an lvalue —

+// a variety of checks:
+//
+// - Check that none of the bound/assigned-to identifiers are reserved words.
+// - Record name declarations for bindings in the appropriate scope.
+// - Check duplicate argument names, if checkClashes is set.
+//
+// If a complex binding pattern is encountered (e.g., object and array
+// destructuring), the entire pattern is recursively checked.
+//
+// There are three versions of checkLVal*() appropriate for different
+// circumstances:
+//
+// - checkLValSimple() shall be used if the syntactic construct supports
+//   nothing other than identifiers and member expressions. Parenthesized
+//   expressions are also correctly handled. This is generally appropriate for
+//   constructs for which the spec says
+//
+//   > It is a Syntax Error if AssignmentTargetType of [the production] is not
+//   > simple.
+//
+//   It is also appropriate for checking if an identifier is valid and not
+//   defined elsewhere, like import declarations or function/class identifiers.
+//
+//   Examples where this is used include:
+//     a += …;
+//     import a from '…';
+//   where a is the node to be checked.
+//
+// - checkLValPattern() shall be used if the syntactic construct supports
+//   anything checkLValSimple() supports, as well as object and array
+//   destructuring patterns. This is generally appropriate for constructs for
+//   which the spec says
+//
+//   > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
+//   > an ArrayLiteral and AssignmentTargetType of [the production] is not
+//   > simple.
+//
+//   Examples where this is used include:
+//     (a = …);
+//     const a = …;
+//     try { … } catch (a) { … }
+//   where a is the node to be checked.
+//
+// - checkLValInnerPattern() shall be used if the syntactic construct supports
+//   anything checkLValPattern() supports, as well as default assignment
+//   patterns, rest elements, and other constructs that may appear within an
+//   object or array destructuring pattern.
+//
+//   As a special case, function parameters also use checkLValInnerPattern(),
+//   as they also support defaults and rest constructs.
+//
+// These functions deliberately support both assignment and binding constructs,
+// as the logic for both is exceedingly similar. If the node is the target of
+// an assignment, then bindingType should be set to BIND_NONE. Otherwise, it
+// should be set to the appropriate BIND_* constant, like BIND_VAR or
+// BIND_LEXICAL.
+//
+// If the function is called with a non-BIND_NONE bindingType, then

+# Source Map JS
+
+[![NPM](https://nodei.co/npm/source-map-js.png?downloads=true&downloadRank=true)](https://www.npmjs.com/package/source-map-js)
+
+Difference between original [source-map](https://github.com/mozilla/source-map):
+
+> TL,DR: it's fork of original source-map@0.6, but with perfomance optimizations.
+
+This journey starts from [source-map@0.7.0](https://github.com/mozilla/source-map/blob/master/CHANGELOG.md#070). Some part of it was rewritten to Rust and WASM and API became async.
+
+It's still a major block for many libraries like PostCSS or Sass for example because they need to migrate the whole API to the async way. This is the reason why 0.6.1 has 2x more downloads than 0.7.3 while it's faster several times.
+
+![Downloads count](media/downloads.png)
+
+More important that WASM version has some optimizations in JS code too. This is why [community asked to create branch for 0.6 version](https://github.com/mozilla/source-map/issues/324) and port these optimizations but, sadly, the answer was «no». A bit later I discovered [the issue](https://github.com/mozilla/source-map/issues/370) created by [Ben Rothman (@benthemonkey)](https://github.com/benthemonkey) with no response at all.
+
+[Roman Dvornov (@lahmatiy)](https://github.com/lahmatiy) wrote a [serveral posts](https://t.me/gorshochekvarit/76) (russian, only, sorry) about source-map library in his own Telegram channel. He mentioned the article [«Maybe you don't need Rust and WASM to speed up your JS»](https://mrale.ph/blog/2018/02/03/maybe-you-dont-need-rust-to-speed-up-your-js.html) written by [Vyacheslav Egorov (@mraleph)](https://github.com/mraleph). This article contains optimizations and hacks that lead to almost the same performance compare to WASM implementation.
+
+I decided to fork the original source-map and port these optimizations from the article and several others PR from the original source-map.
+
+---------
+
+This is a library to generate and consume the source map format
+[described here][format].

+### Generating a source map
+
+In depth guide:
+[**Compiling to JavaScript, and Debugging with Source Maps**](https://hacks.mozilla.org/2013/05/compiling-to-javascript-and-debugging-with-source-maps/)
+
+#### With SourceNode (high level API)
+
+```js
+function compile(ast) {
+  switch (ast.type) {
+  case 'BinaryExpression':
+    return new SourceNode(
+      ast.location.line,
+      ast.location.column,
+      ast.location.source,
+      [compile(ast.left), " + ", compile(ast.right)]
+    );
+  case 'Literal':
+    return new SourceNode(
+      ast.location.line,
+      ast.location.column,
+      ast.location.source,
+      String(ast.value)
+    );
+  // ...
+  default:
+    throw new Error("Bad AST");
+  }
+}
+
+var ast = parse("40 + 2", "add.js");
+console.log(compile(ast).toStringWithSourceMap({
+  file: 'add.js'
+}));
+// { code: '40 + 2',
+//   map: [object SourceMapGenerator] }
+```
+
+#### With SourceMapGenerator (low level API)
+
+```js
+var map = new SourceMapGenerator({
+  file: "source-mapped.js"
+});
+
+map.addMapping({
+  generated: {
+    line: 10,
+    column: 35
+  },
+  source: "foo.js",
+  original: {
+    line: 33,
+    column: 2
+  },
+  name: "christopher"
+});
+
+console.log(map.toString());
+// '{"version":3,"file":"source-mapped.js","sources":["foo.js"],"names":["christopher"],"mappings":";;;;;;;;;mCAgCEA"}'
+```
+
+## API
+
+Get a reference to the module:
+
+```js
+// Node.js
+var sourceMap = require('source-map');
+
+// Browser builds
+var sourceMap = window.sourceMap;
+
+// Inside Firefox
+const sourceMap = require("devtools/toolkit/sourcemap/source-map.js");
+```
+
+### SourceMapConsumer
+
+A SourceMapConsumer instance represents a parsed source map which we can query
+for information about the original file positions by giving it a file position
+in the generated source.
+
+#### new SourceMapConsumer(rawSourceMap)
+
+The only parameter is the raw source map (either as a string which can be
+`JSON.parse`'d, or an object). According to the spec, source maps have the
+following attributes:
+
+* `version`: Which version of the source map spec this map is following.
+
+* `sources`: An array of URLs to the original source files.
+
+* `names`: An array of identifiers which can be referenced by individual
+  mappings.
+
+* `sourceRoot`: Optional. The URL root from which all sources are relative.
+
+* `sourcesContent`: Optional. An array of contents of the original source files.
+
+* `mappings`: A string of base64 VLQs which contain the actual mappings.
+
+* `file`: Optional. The generated filename this source map is associated with.
+
+```js
+var consumer = new sourceMap.SourceMapConsumer(rawSourceMapJsonData);
+```
+
+#### SourceMapConsumer.prototype.computeColumnSpans()
+
+Compute the last column for each generated mapping. The last column is
+inclusive.
+
+```js
+// Before:
+consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1 },
+//   { line: 2,
+//     column: 10 },
+//   { line: 2,
+//     column: 20 } ]
+
+consumer.computeColumnSpans();
+
+// After:
+consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1,
+//     lastColumn: 9 },
+//   { line: 2,
+//     column: 10,
+//     lastColumn: 19 },
+//   { line: 2,
+//     column: 20,
+//     lastColumn: Infinity } ]
+
+```
+
+#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
+
+Returns the original source, line, and column information for the generated
+source's line and column positions provided. The only argument is an object with
+the following properties:
+
+* `line`: The line number in the generated source.  Line numbers in
+  this library are 1-based (note that the underlying source map
+  specification uses 0-based line numbers -- this library handles the
+  translation).
+
+* `column`: The column number in the generated source.  Column numbers
+  in this library are 0-based.
+
+* `bias`: Either `SourceMapConsumer.GREATEST_LOWER_BOUND` or
+  `SourceMapConsumer.LEAST_UPPER_BOUND`. Specifies whether to return the closest
+  element that is smaller than or greater than the one we are searching for,
+  respectively, if the exact element cannot be found.  Defaults to
+  `SourceMapConsumer.GREATEST_LOWER_BOUND`.
+
+and an object is returned with the following properties:
+
+* `source`: The original source file, or null if this information is not
+  available.
+
+* `line`: The line number in the original source, or null if this information is
+  not available.  The line number is 1-based.
+
+* `column`: The column number in the original source, or null if this
+  information is not available.  The column number is 0-based.
+
+* `name`: The original identifier, or null if this information is not available.
+
+```js
+consumer.originalPositionFor({ line: 2, column: 10 })
+// { source: 'foo.coffee',
+//   line: 2,
+//   column: 2,
+//   name: null }
+
+consumer.originalPositionFor({ line: 99999999999999999, column: 999999999999999 })
+// { source: null,
+//   line: null,
+//   column: null,
+//   name: null }
+```
+
+#### SourceMapConsumer.prototype.generatedPositionFor(originalPosition)
+
+Returns the generated line and column information for the original source,
+line, and column positions provided. The only argument is an object with
+the following properties:
+
+* `source`: The filename of the original source.
+
+* `line`: The line number in the original source.  The line number is
+  1-based.
+
+* `column`: The column number in the original source.  The column
+  number is 0-based.
+
+and an object is returned with the following properties:
+
+* `line`: The line number in the generated source, or null.  The line
+  number is 1-based.
+
+* `column`: The column number in the generated source, or null.  The
+  column number is 0-based.
+
+```js
+consumer.generatedPositionFor({ source: "example.js", line: 2, column: 10 })
+// { line: 1,
+//   column: 56 }
+```
+
+#### SourceMapConsumer.prototype.allGeneratedPositionsFor(originalPosition)
+
+Returns all generated line and column information for the original source, line,
+and column provided. If no column is provided, returns all mappings
+corresponding to a either the line we are searching for or the next closest line
+that has any mappings. Otherwise, returns all mappings corresponding to the
+given line and either the column we are searching for or the next closest column
+that has any offsets.
+
+The only argument is an object with the following properties:
+
+* `source`: The filename of the original source.
+
+* `line`: The line number in the original source.  The line number is
+  1-based.
+
+* `column`: Optional. The column number in the original source.  The
+  column number is 0-based.
+
+and an array of objects is returned, each with the following properties:
+
+* `line`: The line number in the generated source, or null.  The line
+  number is 1-based.
+
+* `column`: The column number in the generated source, or null.  The
+  column number is 0-based.
+
+```js
+consumer.allGeneratedpositionsfor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1 },
+//   { line: 2,
+//     column: 10 },
+//   { line: 2,
+//     column: 20 } ]
+```
+
+#### SourceMapConsumer.prototype.hasContentsOfAllSources()
+
+Return true if we have the embedded source content for every source listed in
+the source map, false otherwise.
+
+In other words, if this method returns `true`, then
+`consumer.sourceContentFor(s)` will succeed for every source `s` in
+`consumer.sources`.
+
+```js
+// ...
+if (consumer.hasContentsOfAllSources()) {
+  consumerReadyCallback(consumer);
+} else {
+  fetchSources(consumer, consumerReadyCallback);
+}
+// ...
+```
+
+#### SourceMapConsumer.prototype.sourceContentFor(source[, returnNullOnMissing])
+
+Returns the original source content for the source provided. The only
+argument is the URL of the original source file.
+
+If the source content for the given source is not found, then an error is
+thrown. Optionally, pass `true` as the second param to have `null` returned
+instead.
+
+```js
+consumer.sources
+// [ "my-cool-lib.clj" ]
+
+consumer.sourceContentFor("my-cool-lib.clj")
+// "..."
+
+consumer.sourceContentFor("this is not in the source map");
+// Error: "this is not in the source map" is not in the source map
+
+consumer.sourceContentFor("this is not in the source map", true);
+// null
+```
+
+#### SourceMapConsumer.prototype.eachMapping(callback, context, order)
+
+Iterate over each mapping between an original source/line/column and a
+generated line/column in this source map.
+
+* `callback`: The function that is called with each mapping. Mappings have the
+  form `{ source, generatedLine, generatedColumn, originalLine, originalColumn,
+  name }`
+
+* `context`: Optional. If specified, this object will be the value of `this`
+  every time that `callback` is called.
+
+* `order`: Either `SourceMapConsumer.GENERATED_ORDER` or
+  `SourceMapConsumer.ORIGINAL_ORDER`. Specifies whether you want to iterate over
+  the mappings sorted by the generated file's line/column order or the
+  original's source/line/column order, respectively. Defaults to
+  `SourceMapConsumer.GENERATED_ORDER`.
+
+```js
+consumer.eachMapping(function (m) { console.log(m); })
+// ...
+// { source: 'illmatic.js',
+//   generatedLine: 1,
+//   generatedColumn: 0,
+//   originalLine: 1,
+//   originalColumn: 0,
+//   name: null }
+// { source: 'illmatic.js',
+//   generatedLine: 2,
+//   generatedColumn: 0,
+//   originalLine: 2,
+//   originalColumn: 0,
+//   name: null }
+// ...
+```
+### SourceMapGenerator
+
+An instance of the SourceMapGenerator represents a source map which is being
+built incrementally.
+
+#### new SourceMapGenerator([startOfSourceMap])
+
+You may pass an object with the following properties:
+
+* `file`: The filename of the generated source that this source map is
+  associated with.
+
+* `sourceRoot`: A root for all relative URLs in this source map.
+
+* `skipValidation`: Optional. When `true`, disables validation of mappings as
+  they are added. This can improve performance but should be used with
+  discretion, as a last resort. Even then, one should avoid using this flag when
+  running tests, if possible.
+
+* `ignoreInvalidMapping`: Optional. When `true`, instead of throwing error on
+  invalid mapping, it will be ignored.
+
+```js
+var generator = new sourceMap.SourceMapGenerator({
+  file: "my-generated-javascript-file.js",
+  sourceRoot: "http://example.com/app/js/"
+});
+```
+
+#### SourceMapGenerator.fromSourceMap(sourceMapConsumer, sourceMapGeneratorOptions)
+
+Creates a new `SourceMapGenerator` from an existing `SourceMapConsumer` instance.
+
+* `sourceMapConsumer` The SourceMap.
+
+* `sourceMapGeneratorOptions` options that will be passed to the SourceMapGenerator constructor which used under the hood.
+
+```js
+var generator = sourceMap.SourceMapGenerator.fromSourceMap(consumer, {
+  ignoreInvalidMapping: true,
+});
+```
+
+#### SourceMapGenerator.prototype.addMapping(mapping)
+
+Add a single mapping from original source line and column to the generated
+source's line and column for this source map being created. The mapping object
+should have the following properties:
+
+* `generated`: An object with the generated line and column positions.
+
+* `original`: An object with the original line and column positions.
+
+* `source`: The original source file (relative to the sourceRoot).
+
+* `name`: An optional original token name for this mapping.
+
+```js
+generator.addMapping({
+  source: "module-one.scm",
+  original: { line: 128, column: 0 },
+  generated: { line: 3, column: 456 }
+})
+```
+
+#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for an original source file.
+
+* `sourceFile` the URL of the original source file.
+
+* `sourceContent` the content of the source file.
+
+```js
+generator.setSourceContent("module-one.scm",
+                           fs.readFileSync("path/to/module-one.scm"))
+```
+
+#### SourceMapGenerator.prototype.applySourceMap(sourceMapConsumer[, sourceFile[, sourceMapPath]])
+
+Applies a SourceMap for a source file to the SourceMap.
+Each mapping to the supplied source file is rewritten using the
+supplied SourceMap. Note: The resolution for the resulting mappings
+is the minimum of this map and the supplied map.
+
+* `sourceMapConsumer`: The SourceMap to be applied.
+
+* `sourceFile`: Optional. The filename of the source file.
+  If omitted, sourceMapConsumer.file will be used, if it exists.
+  Otherwise an error will be thrown.
+
+* `sourceMapPath`: Optional. The dirname of the path to the SourceMap
+  to be applied. If relative, it is relative to the SourceMap.
+
+  This parameter is needed when the two SourceMaps aren't in the same
+  directory, and the SourceMap to be applied contains relative source
+  paths. If so, those relative source paths need to be rewritten
+  relative to the SourceMap.
+
+  If omitted, it is assumed that both SourceMaps are in the same directory,
+  thus not needing any rewriting. (Supplying `'.'` has the same effect.)
+
+#### SourceMapGenerator.prototype.toString()
+
+Renders the source map being generated to a string.
+
+```js
+generator.toString()
+// '{"version":3,"sources":["module-one.scm"],"names":[],"mappings":"...snip...","file":"my-generated-javascript-file.js","sourceRoot":"http://example.com/app/js/"}'
+```
+
+### SourceNode
+
+SourceNodes provide a way to abstract over interpolating and/or concatenating
+snippets of generated JavaScript source code, while maintaining the line and
+column information associated between those snippets and the original source
+code. This is useful as the final intermediate representation a compiler might
+use before outputting the generated JS and source map.
+
+#### new SourceNode([line, column, source[, chunk[, name]]])
+
+* `line`: The original line number associated with this source node, or null if
+  it isn't associated with an original line.  The line number is 1-based.
+
+* `column`: The original column number associated with this source node, or null
+  if it isn't associated with an original column.  The column number
+  is 0-based.
+
+* `source`: The original source's filename; null if no filename is provided.
+
+* `chunk`: Optional. Is immediately passed to `SourceNode.prototype.add`, see
+  below.
+
+* `name`: Optional. The original identifier.
+
+```js
+var node = new SourceNode(1, 2, "a.cpp", [
+  new SourceNode(3, 4, "b.cpp", "extern int status;\n"),
+  new SourceNode(5, 6, "c.cpp", "std::string* make_string(size_t n);\n"),

+
+* `code`: The generated code
+
+* `sourceMapConsumer` The SourceMap for the generated code
+
+* `relativePath` The optional path that relative sources in `sourceMapConsumer`
+  should be relative to.
+
+```js
+var consumer = new SourceMapConsumer(fs.readFileSync("path/to/my-file.js.map", "utf8"));
+var node = SourceNode.fromStringWithSourceMap(fs.readFileSync("path/to/my-file.js"),
+                                              consumer);
+```
+
+#### SourceNode.prototype.add(chunk)
+
+Add a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+   `SourceNode`, or an array where each member is one of those things.
+
+```js
+node.add(" + ");
+node.add(otherNode);
+node.add([leftHandOperandNode, " + ", rightHandOperandNode]);
+```
+
+#### SourceNode.prototype.prepend(chunk)
+
+Prepend a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+   `SourceNode`, or an array where each member is one of those things.
+
+```js
+node.prepend("/** Build Id: f783haef86324gf **/\n\n");
+```
+
+#### SourceNode.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for a source file. This will be added to the
+`SourceMap` in the `sourcesContent` field.
+
+* `sourceFile`: The filename of the source file
+
+* `sourceContent`: The content of the source file
+
+```js
+node.setSourceContent("module-one.scm",

+```
+
+#### SourceNode.prototype.walk(fn)
+
+Walk over the tree of JS snippets in this node and its children. The walking
+function is called once for each snippet of JS and is passed that snippet and
+the its original associated source's line/column location.
+
+* `fn`: The traversal function.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")
+  ]
+]);
+
+node.walk(function (code, loc) { console.log("WALK:", code, loc); })
+// WALK: uno { source: 'b.js', line: 3, column: 4, name: null }
+// WALK: dos { source: 'a.js', line: 1, column: 2, name: null }

+```
+
+#### SourceNode.prototype.walkSourceContents(fn)
+
+Walk over the tree of SourceNodes. The walking function is called for each
+source file content and is passed the filename and source content.
+
+* `fn`: The traversal function.
+
+```js
+var a = new SourceNode(1, 2, "a.js", "generated from a");
+a.setSourceContent("a.js", "original a");
+var b = new SourceNode(1, 2, "b.js", "generated from b");
+b.setSourceContent("b.js", "original b");
+var c = new SourceNode(1, 2, "c.js", "generated from c");
+c.setSourceContent("c.js", "original c");
+
+var node = new SourceNode(null, null, null, [a, b, c]);
+node.walkSourceContents(function (source, contents) { console.log("WALK:", source, ":", contents); })
+// WALK: a.js : original a
+// WALK: b.js : original b
+// WALK: c.js : original c
+```
+

+var operand = new SourceNode(3, 4, "a.rs", "=");
+var rhs = new SourceNode(5, 6, "a.rs", "orig.clone()");
+
+var node = new SourceNode(null, null, null, [ lhs, operand, rhs ]);
+var joinedNode = node.join(" ");
+```
+
+#### SourceNode.prototype.replaceRight(pattern, replacement)
+
+Call `String.prototype.replace` on the very right-most source snippet. Useful
+for trimming white space from the end of a source node, etc.
+
+* `pattern`: The pattern to replace.
+
+* `replacement`: The thing to replace the pattern with.
+
+```js
+// Trim trailing white space.
+node.replaceRight(/\s*$/, "");
+```
+
+#### SourceNode.prototype.toString()
+
+Return the string representation of this source node. Walks over the tree and
+concatenates all the various snippets together to one string.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")
+  ]
+]);
+
+node.toString()
+// 'unodostresquatro'
+```
+
+#### SourceNode.prototype.toStringWithSourceMap([startOfSourceMap])
+
+Returns the string representation of this tree of source nodes, plus a
+SourceMapGenerator which contains all the mappings between the generated and
+original sources.
+
+The arguments are the same as those to `new SourceMapGenerator`.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")

+ *
+ * Here is an example source map, taken from the source map spec[0]:

+ * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
+ * input.
+ *
+ * The first parameter is a raw source map (either as a JSON string, or already
+ * parsed to an object). According to the spec for indexed source maps, they
+ * have the following attributes:
+ *
+ *   - version: Which version of the source map spec this map is following.
+ *   - file: Optional. The generated file this source map is associated with.
+ *   - sections: A list of section definitions.
+ *
+ * Each value under the "sections" field has two fields:
+ *   - offset: The offset into the original specified at which this section
+ *       begins to apply, defined as an object with a "line" and "column"
+ *       field.
+ *   - map: A source map definition. This source map could also be indexed,
+ *       but doesn't have to be.
+ *
+ * Instead of the "map" field, it's also possible to have a "url" field
+ * specifying a URL to retrieve a source map from, but that's currently
+ * unsupported.
+ *
+ * Here's an example source map, taken from the source map spec[0], but
+ * modified to omit a section which uses the "url" field.
+ *
+ *  {
+ *    version : 3,
+ *    file: "app.js",
+ *    sections: [{
+ *      offset: {line:100, column:10},
+ *      map: {
+ *        version : 3,
+ *        file: "section.js",
+ *        sources: ["foo.js", "bar.js"],
+ *        names: ["src", "maps", "are", "fun"],
+ *        mappings: "AAAA,E;;ABCDE;"
+ *      }
+ *    }],
+ *  }
+ *
+ * The second parameter, if given, is a string whose value is the URL
+ * at which the source map was found.  This URL is used to compute the
+ * sources array.
+ *

+TweetNaCl.js Changelog
+======================
+
+v1.0.3
+------
+
+***IMPORTANT BUG FIX***. Due to a bug in calculating carry in
+modulo reduction that used bit operations on integers larger than
+32 bits, `nacl.sign` or `nacl.sign.detached` could have created
+incorrect signatures.
+
+This only affects signing, not verification.
+
+Thanks to @valerini on GitHub for finding and reporting the bug.
+
+
+v1.0.2
+------
+
+Exported more internal undocumented functions for
+third-party projects that rely on low-level interface,
+(something users of TweetNaCl shouldn't care about).
+
+
+v1.0.1
+------
+
+Updated documentation and typings.
+
+
+v1.0.0
+------
+
+No code changes from v1.0.0-rc.1.
+
+
+v1.0.0-rc.1
+-----------
+
+* **IMPORTANT!** In previous versions, `nacl.secretbox.open`, `nacl.box.open`,
+  and `nacl.box.after` returned `false` when opening failed (for example, when
+  using incorrect key, nonce, or when input was maliciously or accidentally
+  modified after encryption). This version instead returns `null`.
+
+  The usual way to check for this condition:
+
+  `if (!result) { ... }`
+
+  is correct and will continue to work.
+
+  However, direct comparison with `false`:
+
+  `if (result == false) { ... }`
+
+  it will no longer work and **will not detect failure**. Please check
+  your code for this condition.
+
+  (`nacl.sign.open` always returned `null`, so it is not affected.)
+
+
+* Arguments type check now uses `instanceof Uint8Array` instead of `Object.prototype.toString`.
+* Removed deprecation checks for `nacl.util` (moved to a
+  [separate package](https://github.com/dchest/tweetnacl-util-js) in v0.14.0).
+* Removed deprecation checks for the old signature API (changed in v0.10.0).
+* Improved benchmarking.
+
+v0.14.5
+-------
+
+* Fixed incomplete return types in TypeScript typings.
+* Replaced COPYING.txt with LICENSE file, which now has public domain dedication
+  text from The Unlicense. License fields in package.json and bower.json have
+  been set to "Unlicense". The project was and will be in the public domain --
+  this change just makes it easier for automated tools to know about this fact by
+  using the widely recognized and SPDX-compatible template for public domain
+  dedication.
+
+
+v0.14.4
+-------
+
+* Added TypeScript type definitions (contributed by @AndSDev).
+* Improved benchmarking code.
+
+
+v0.14.3
+-------
+
+Fixed a bug in the fast version of Poly1305 and brought it back.
+
+Thanks to @floodyberry for promptly responding and fixing the original C code:
+
+> "The issue was not properly detecting if st->h was >= 2^130 - 5, coupled with
+> [testing mistake] not catching the failure. The chance of the bug affecting
+> anything in the real world is essentially zero luckily, but it's good to have
+> it fixed."
+
+https://github.com/floodyberry/poly1305-donna/issues/2#issuecomment-202698577
+
+
+v0.14.2
+-------
+
+Switched Poly1305 fast version back to original (slow) version due to a bug.
+
+
+v0.14.1
+-------
+
+No code changes, just tweaked packaging and added COPYING.txt.
+
+
+v0.14.0
+-------
+
+* **Breaking change!** All functions from `nacl.util` have been removed. These
+  functions are no longer available:
+
+      nacl.util.decodeUTF8
+      nacl.util.encodeUTF8
+      nacl.util.decodeBase64
+      nacl.util.encodeBase64
+
+  If want to continue using them, you can include
+  <https://github.com/dchest/tweetnacl-util-js> package:
+
+      <script src="nacl.min.js"></script>
+      <script src="nacl-util.min.js"></script>
+
+  or
+
+      var nacl = require('tweetnacl');
+      nacl.util = require('tweetnacl-util');
+
+  However it is recommended to use better packages that have wider
+  compatibility and better performance. Functions from `nacl.util` were never
+  intended to be robust solution for string conversion and were included for
+  convenience: cryptography library is not the right place for them.
+
+  Currently calling these functions will throw error pointing to
+  `tweetnacl-util-js` (in the next version this error message will be removed).
+
+* Improved detection of available random number generators, making it possible
+  to use `nacl.randomBytes` and related functions in Web Workers without
+  changes.
+
+* Changes to testing (see README).
+
+
+v0.13.3
+-------
+
+No code changes.
+
+* Reverted license field in package.json to "Public domain".
+
+* Fixed typo in README.
+
+
+v0.13.2
+-------
+
+* Fixed undefined variable bug in fast version of Poly1305. No worries, this
+  bug was *never* triggered.
+
+* Specified CC0 public domain dedication.
+
+* Updated development dependencies.
+
+
+v0.13.1
+-------
+
+* Exclude `crypto` and `buffer` modules from browserify builds.
+
+
+v0.13.0
+-------
+
+* Made `nacl-fast` the default version in NPM package. Now
+  `require("tweetnacl")` will use fast version; to get the original version,
+  use `require("tweetnacl/nacl.js")`.
+
+* Cleanup temporary array after generating random bytes.
+
+
+v0.12.2
+-------
+
+* Improved performance of curve operations, making `nacl.scalarMult`, `nacl.box`,
+  `nacl.sign` and related functions up to 3x faster in `nacl-fast` version.
+
+
+v0.12.1
+-------
+
+* Significantly improved performance of Salsa20 (~1.5x faster) and
+  Poly1305 (~3.5x faster) in `nacl-fast` version.
+
+
+v0.12.0
+-------
+
+* Instead of using the given secret key directly, TweetNaCl.js now copies it to
+  a new array in `nacl.box.keyPair.fromSecretKey` and
+  `nacl.sign.keyPair.fromSecretKey`.
+
+
+v0.11.2
+-------
+
+* Added new constant: `nacl.sign.seedLength`.
+
+
+v0.11.1
+-------
+
+* Even faster hash for both short and long inputs (in `nacl-fast`).
+
+
+v0.11.0
+-------
+
+* Implement `nacl.sign.keyPair.fromSeed` to enable creation of sign key pairs
+  deterministically from a 32-byte seed. (It behaves like
+  [libsodium's](http://doc.libsodium.org/public-key_cryptography/public-key_signatures.html)
+  `crypto_sign_seed_keypair`: the seed becomes a secret part of the secret key.)
+
+* Fast version now has an improved hash implementation that is 2x-5x faster.
+
+* Fixed benchmarks, which may have produced incorrect measurements.
+
+
+v0.10.1
+-------
+
+* Exported undocumented `nacl.lowlevel.crypto_core_hsalsa20`.
+
+
+v0.10.0
+-------
+
+* **Signature API breaking change!** `nacl.sign` and `nacl.sign.open` now deal
+ with signed messages, and new `nacl.sign.detached` and
+ `nacl.sign.detached.verify` are available.
+
+ Previously, `nacl.sign` returned a signature, and `nacl.sign.open` accepted a
+ message and "detached" signature. This was unlike NaCl's API, which dealt with
+ signed messages (concatenation of signature and message).
+
+ The new API is:
+
+      nacl.sign(message, secretKey) -> signedMessage
+      nacl.sign.open(signedMessage, publicKey) -> message | null
+
+ Since detached signatures are common, two new API functions were introduced:
+
+      nacl.sign.detached(message, secretKey) -> signature
+      nacl.sign.detached.verify(message, signature, publicKey) -> true | false
+
+ (Note that it's `verify`, not `open`, and it returns a boolean value, unlike
+ `open`, which returns an "unsigned" message.)
+
+* NPM package now comes without `test` directory to keep it small.
+
+
+v0.9.2
+------
+
+* Improved documentation.
+* Fast version: increased theoretical message size limit from 2^32-1 to 2^52
+  bytes in Poly1305 (and thus, secretbox and box). However this has no impact
+  in practice since JavaScript arrays or ArrayBuffers are limited to 32-bit
+  indexes, and most implementations won't allocate more than a gigabyte or so.
+  (Obviously, there are no tests for the correctness of implementation.) Also,
+  it's not recommended to use messages that large without splitting them into
+  smaller packets anyway.
+
+
+v0.9.1
+------
+
+* Initial release

+
+Overview
+--------
+
+The primary goal of this project is to produce a translation of TweetNaCl to
+JavaScript which is as close as possible to the original C implementation, plus
+a thin layer of idiomatic high-level API on top of it.
+
+There are two versions, you can use either of them:
+
+* `nacl.js` is the port of TweetNaCl with minimum differences from the
+  original + high-level API.
+
+* `nacl-fast.js` is like `nacl.js`, but with some functions replaced with
+  faster versions. (Used by default when importing NPM package.)
+
+
+Audits
+------
+
+TweetNaCl.js has been audited by [Cure53](https://cure53.de/) in January-February
+2017 (audit was sponsored by [Deletype](https://deletype.com)):
+
+> The overall outcome of this audit signals a particularly positive assessment
+> for TweetNaCl-js, as the testing team was unable to find any security
+> problems in the library. It has to be noted that this is an exceptionally
+> rare result of a source code audit for any project and must be seen as a true
+> testament to a development proceeding with security at its core.
+>
+> To reiterate, the TweetNaCl-js project, the source code was found to be
+> bug-free at this point.
+>
+> [...]
+>
+> In sum, the testing team is happy to recommend the TweetNaCl-js project as
+> likely one of the safer and more secure cryptographic tools among its
+> competition.

+
+
+Installation
+------------
+
+You can install TweetNaCl.js via a package manager:
+
+[Yarn](https://yarnpkg.com/):
+
+    $ yarn add tweetnacl
+
+[NPM](https://www.npmjs.org/):
+
+    $ npm install tweetnacl
+
+or [download source code](https://github.com/dchest/tweetnacl-js/releases).
+
+
+Examples
+--------
+You can find usage examples in our [wiki](https://github.com/dchest/tweetnacl-js/wiki/Examples).
+
+
+Usage
+-----
+
+All API functions accept and return bytes as `Uint8Array`s.  If you need to
+encode or decode strings, use functions from
+<https://github.com/dchest/tweetnacl-util-js> or one of the more robust codec
+packages.
+
+In Node.js v4 and later `Buffer` objects are backed by `Uint8Array`s, so you
+can freely pass them to TweetNaCl.js functions as arguments. The returned
+objects are still `Uint8Array`s, so if you need `Buffer`s, you'll have to
+convert them manually; make sure to convert using copying: `Buffer.from(array)`
+(or `new Buffer(array)` in Node.js v4 or earlier), instead of sharing:
+`Buffer.from(array.buffer)` (or `new Buffer(array.buffer)` Node 4 or earlier),
+because some functions return subarrays of their buffers.
+
+
+### Public-key authenticated encryption (box)
+
+Implements *x25519-xsalsa20-poly1305*.
+
+#### nacl.box.keyPair()
+
+Generates a new random key pair for box and returns it as an object with
+`publicKey` and `secretKey` members:
+
+    {
+       publicKey: ...,  // Uint8Array with 32-byte public key
+       secretKey: ...   // Uint8Array with 32-byte secret key
+    }
+
+
+#### nacl.box.keyPair.fromSecretKey(secretKey)
+
+Returns a key pair for box with public key corresponding to the given secret
+key.
+
+#### nacl.box(message, nonce, theirPublicKey, mySecretKey)
+
+Encrypts and authenticates message using peer's public key, our secret key, and
+the given nonce, which must be unique for each distinct message for a key pair.

+Authenticates and decrypts the given box with peer's public key, our secret
+key, and the given nonce.
+
+Returns the original message, or `null` if authentication fails.
+
+#### nacl.box.before(theirPublicKey, mySecretKey)
+
+Returns a precomputed shared key which can be used in `nacl.box.after` and
+`nacl.box.open.after`.
+
+#### nacl.box.after(message, nonce, sharedKey)
+
+Same as `nacl.box`, but uses a shared key precomputed with `nacl.box.before`.
+
+#### nacl.box.open.after(box, nonce, sharedKey)
+
+Same as `nacl.box.open`, but uses a shared key precomputed with `nacl.box.before`.
+
+#### Constants
+
+##### nacl.box.publicKeyLength = 32
+
+Length of public key in bytes.
+
+##### nacl.box.secretKeyLength = 32
+
+Length of secret key in bytes.
+
+##### nacl.box.sharedKeyLength = 32
+
+Length of precomputed shared key in bytes.
+
+##### nacl.box.nonceLength = 24
+
+Length of nonce in bytes.
+
+##### nacl.box.overheadLength = 16
+
+Length of overhead added to box compared to original message.
+
+
+### Secret-key authenticated encryption (secretbox)
+
+Implements *xsalsa20-poly1305*.
+
+#### nacl.secretbox(message, nonce, key)
+
+Encrypts and authenticates message using the key and the nonce. The nonce must
+be unique for each distinct message for this key.
+
+Returns an encrypted and authenticated message, which is
+`nacl.secretbox.overheadLength` longer than the original message.
+

+
+Length of key in bytes.
+
+##### nacl.secretbox.nonceLength = 24
+
+Length of nonce in bytes.
+
+##### nacl.secretbox.overheadLength = 16
+
+Length of overhead added to secret box compared to original message.
+
+
+### Scalar multiplication
+
+Implements *x25519*.

+group element.
+
+#### nacl.scalarMult.base(n)
+
+Multiplies an integer `n` by a standard group element and returns the resulting
+group element.
+
+#### Constants
+
+##### nacl.scalarMult.scalarLength = 32
+
+Length of scalar in bytes.
+
+##### nacl.scalarMult.groupElementLength = 32
+
+Length of group element in bytes.
+
+
+### Signatures
+
+Implements [ed25519](http://ed25519.cr.yp.to).
+
+#### nacl.sign.keyPair()
+
+Generates new random key pair for signing and returns it as an object with
+`publicKey` and `secretKey` members:
+
+    {
+       publicKey: ...,  // Uint8Array with 32-byte public key
+       secretKey: ...   // Uint8Array with 64-byte secret key
+    }
+
+#### nacl.sign.keyPair.fromSecretKey(secretKey)
+
+Returns a signing key pair with public key corresponding to the given
+64-byte secret key. The secret key must have been generated by
+`nacl.sign.keyPair` or `nacl.sign.keyPair.fromSeed`.
+
+#### nacl.sign.keyPair.fromSeed(seed)
+
+Returns a new signing key pair generated deterministically from a 32-byte seed.
+The seed must contain enough entropy to be secure. This method is not
+recommended for general use: instead, use `nacl.sign.keyPair` to generate a new
+key pair from a random seed.
+
+#### nacl.sign(message, secretKey)
+
+Signs the message using the secret key and returns a signed message.
+
+#### nacl.sign.open(signedMessage, publicKey)
+
+Verifies the signed message and returns the message without signature.
+
+Returns `null` if verification failed.
+
+#### nacl.sign.detached(message, secretKey)
+
+Signs the message using the secret key and returns a signature.
+
+#### nacl.sign.detached.verify(message, signature, publicKey)
+
+Verifies the signature for the message and returns `true` if verification
+succeeded or `false` if it failed.
+
+#### Constants
+
+##### nacl.sign.publicKeyLength = 32
+
+Length of signing public key in bytes.
+
+##### nacl.sign.secretKeyLength = 64
+
+Length of signing secret key in bytes.
+
+##### nacl.sign.seedLength = 32
+
+Length of seed for `nacl.sign.keyPair.fromSeed` in bytes.
+
+##### nacl.sign.signatureLength = 64
+
+Length of signature in bytes.
+
+
+### Hashing
+
+Implements *SHA-512*.
+
+#### nacl.hash(message)
+
+Returns SHA-512 hash of the message.
+
+#### Constants
+
+##### nacl.hash.hashLength = 64
+
+Length of hash in bytes.
+
+
+### Random bytes generation
+
+#### nacl.randomBytes(length)
+
+Returns a `Uint8Array` of the given length containing random bytes of
+cryptographic quality.
+
+**Implementation note**
+
+TweetNaCl.js uses the following methods to generate random bytes,
+depending on the platform it runs on:
+
+* `window.crypto.getRandomValues` (WebCrypto standard)
+* `window.msCrypto.getRandomValues` (Internet Explorer 11)
+* `crypto.randomBytes` (Node.js)
+
+If the platform doesn't provide a suitable PRNG, the following functions,
+which require random numbers, will throw exception:
+
+* `nacl.randomBytes`
+* `nacl.box.keyPair`
+* `nacl.sign.keyPair`
+
+Other functions are deterministic and will continue working.
+
+If a platform you are targeting doesn't implement secure random number
+generator, but you somehow have a cryptographically-strong source of entropy
+(not `Math.random`!), and you know what you are doing, you can plug it into
+TweetNaCl.js like this:
+
+    nacl.setPRNG(function(x, n) {
+      // ... copy n random bytes into x ...
+    });
+
+Note that `nacl.setPRNG` *completely replaces* internal random byte generator
+with the one provided.
+
+
+### Constant-time comparison
+
+#### nacl.verify(x, y)
+
+Compares `x` and `y` in constant time and returns `true` if their lengths are
+non-zero and equal, and their contents are equal.
+
+Returns `false` if either of the arguments has zero length, or arguments have
+different lengths, or their contents differ.
+
+
+System requirements
+-------------------
+
+TweetNaCl.js supports modern browsers that have a cryptographically secure
+pseudorandom number generator and typed arrays, including the latest versions
+of:
+
+* Chrome
+* Firefox
+* Safari (Mac, iOS)
+* Internet Explorer 11
+
+Other systems:
+
+* Node.js
+
+
+Development and testing
+------------------------
+
+Install NPM modules needed for development:
+
+    $ npm install
+
+To build minified versions:
+
+    $ npm run build
+
+Tests use minified version, so make sure to rebuild it every time you change
+`nacl.js` or `nacl-fast.js`.
+
+### Testing
+
+To run tests in Node.js:
+
+    $ npm run test-node
+
+By default all tests described here work on `nacl.min.js`. To test other
+versions, set environment variable `NACL_SRC` to the file name you want to test.
+For example, the following command will test fast minified version:
+
+    $ NACL_SRC=nacl-fast.min.js npm run test-node
+
+To run full suite of tests in Node.js, including comparing outputs of
+JavaScript port to outputs of the original C version:
+
+    $ npm run test-node-all
+
+To prepare tests for browsers:
+
+    $ npm run build-test-browser
+
+and then open `test/browser/test.html` (or `test/browser/test-fast.html`) to
+run them.
+
+To run tests in both Node and Electron:
+
+    $ npm test
+
+### Benchmarking
+
+To run benchmarks in Node.js:
+
+    $ npm run bench
+    $ NACL_SRC=nacl-fast.min.js npm run bench
+
+To run benchmarks in a browser, open `test/benchmark/bench.html` (or
+`test/benchmark/bench-fast.html`).
+

+In short, with *nacl-fast.js* and 1024-byte messages you can expect to encrypt and
+authenticate more than 57000 messages per second on a typical laptop or more than
+14000 messages per second on a $170 smartphone, sign about 200 and verify 100
+messages per second on a laptop or 60 and 30 messages per second on a smartphone,
+per CPU core (with Web Workers you can do these operations in parallel),
+which is good enough for most applications.

+
+## Why? 🤔
+
+When using _[Vite Ruby]_, I wanted to see changes to server-rendered layouts and templates without having to manually reload the page.
+
+Also, in _[JS From Routes]_ path helpers are generated when Rails reload is triggered.
+
+Triggering a page reload when `config/routes.rb` is modified makes the DX very smooth.
+
+## Installation 💿
+
+Install the package as a development dependency:
+
+```bash
+npm i -D vite-plugin-full-reload # yarn add -D vite-plugin-full-reload
+```
+
+## Usage 🚀
+
+Add it to your plugins in `vite.config.ts`
+
+```ts
+import { defineConfig } from 'vite'
+import FullReload from 'vite-plugin-full-reload'
+
+export default defineConfig({
+  plugins: [
+    FullReload(['config/routes.rb', 'app/views/**/*'])
+  ],
+})
+```
+
+This is useful to trigger a page refresh for files that are not being imported, such as server-rendered templates.
+
+To see which file globbing options are available, check [picomatch].
+
+## Configuration ⚙️
+
+The following options can be provided:
+
+- <kbd>root</kbd>
+  
+  Files will be resolved against this directory.
+
+  __Default:__ `process.cwd()`
+
+  ``` js
+  FullReload('config/routes.rb', { root: __dirname }),
+  ``` 
+
+- <kbd>delay</kbd>
+
+  How many milliseconds to wait before reloading the page after a file change.
+  It can be used to offset slow template compilation in Rails.
+
+  __Default:__ `0`
+  
+  ```js
+  FullReload('app/views/**/*', { delay: 100 })
+  ``` 
+
+- <kbd>always</kbd>
+
+  Whether to refresh the page even if the modified HTML file is not currently being displayed.
+
+  __Default:__ `true`
+  
+  ```js
+  FullReload('app/views/**/*', { always: false })
+  ``` 
+
+## Acknowledgements
+
+- <kbd>[vite-plugin-live-reload]</kbd>
+
+  This is a nice plugin, I found it right before publishing this one.
+
+  I've made [two](https://github.com/arnoson/vite-plugin-live-reload/pull/3) [PRs](https://github.com/arnoson/vite-plugin-live-reload/pull/5) that were needed to support these use cases.
+
+  At this point in time they are very similar, except this library doesn't create another `chokidar` watcher.

+>           that You distribute, all copyright, patent, trademark, and
+>           attribution notices from the Source form of the Work,
+>           excluding those notices that do not pertain to any part of
+>           the Derivative Works; and

+>       (d) If the Work includes a "NOTICE" text file as part of its
+>           distribution, then any Derivative Works that You distribute must
+>           include a readable copy of the attribution notices contained
+>           within such NOTICE file, excluding those notices that do not
+>           pertain to any part of the Derivative Works, in at least one
+>           of the following places: within a NOTICE text file distributed
+>           as part of the Derivative Works; within the Source form or
+>           documentation, if provided along with the Derivative Works; or,
+>           within a display generated by the Derivative Works, if and
+>           wherever such third-party notices normally appear. The contents
+>           of the NOTICE file are for informational purposes only and
+>           do not modify the License. You may add Your own attribution
+>           notices within Derivative Works that You distribute, alongside
+>           or as an addendum to the NOTICE text from the Work, provided
+>           that such additional attribution notices cannot be construed
+>           as modifying the License.
+> 
+>       You may add Your own copyright statement to Your modifications and
+>       may provide additional or different license terms and conditions
+>       for use, reproduction, or distribution of Your modifications, or
+>       for any such Derivative Works as a whole, provided Your use,
+>       reproduction, and distribution of the Work otherwise complies with
+>       the conditions stated in this License.
+> 
+>    5. Submission of Contributions. Unless You explicitly state otherwise,
+>       any Contribution intentionally submitted for inclusion in the Work
+>       by You to the Licensor shall be under the terms and conditions of
+>       this License, without any additional terms or conditions.
+>       Notwithstanding the above, nothing herein shall supersede or modify
+>       the terms of any separate license agreement you may have executed
+>       with Licensor regarding such Contributions.
+> 
+>    6. Trademarks. This License does not grant permission to use the trade
+>       names, trademarks, service marks, or product names of the Licensor,
+>       except as required for reasonable and customary use in describing the
+>       origin of the Work and reproducing the content of the NOTICE file.
+> 
+>    7. Disclaimer of Warranty. Unless required by applicable law or
+>       agreed to in writing, Licensor provides the Work (and each
+>       Contributor provides its Contributions) on an "AS IS" BASIS,
+>       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+>       implied, including, without limitation, any warranties or conditions
+>       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+>       PARTICULAR PURPOSE. You are solely responsible for determining the
+>       appropriateness of using or redistributing the Work and assume any
+>       risks associated with Your exercise of permissions under this License.
+> 
+>    8. Limitation of Liability. In no event and under no legal theory,
+>       whether in tort (including negligence), contract, or otherwise,
+>       unless required by applicable law (such as deliberate and grossly
+>       negligent acts) or agreed to in writing, shall any Contributor be
+>       liable to You for damages, including any direct, indirect, special,
+>       incidental, or consequential damages of any character arising as a
+>       result of this License or out of the use or inability to use the
+>       Work (including but not limited to damages for loss of goodwill,
+>       work stoppage, computer failure or malfunction, or any and all
+>       other commercial damages or losses), even if such Contributor
+>       has been advised of the possibility of such damages.
+> 
+>    9. Accepting Warranty or Additional Liability. While redistributing
+>       the Work or Derivative Works thereof, You may choose to offer,
+>       and charge a fee for, acceptance of support, warranty, indemnity,
+>       or other liability obligations and/or rights consistent with this
+>       License. However, in accepting such obligations, You may act only
+>       on Your own behalf and on Your sole responsibility, not on behalf
+>       of any other Contributor, and only if You agree to indemnify,

+# vite ⚡
+
+> Next Generation Frontend Tooling
+
+- 💡 Instant Server Start
+- ⚡️ Lightning Fast HMR
+- 🛠️ Rich Features
+- 📦 Optimized Build
+- 🔩 Universal Plugin Interface
+- 🔑 Fully Typed APIs
+
+Vite (French word for "fast", pronounced `/vit/`) is a new breed of frontend build tool that significantly improves the frontend development experience. It consists of two major parts:
+
+- A dev server that serves your source files over [native ES modules](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules), with [rich built-in features](https://vitejs.dev/guide/features.html) and astonishingly fast [Hot Module Replacement (HMR)](https://vitejs.dev/guide/features.html#hot-module-replacement).
+
+- A [build command](https://vitejs.dev/guide/build.html) that bundles your code with [Rollup](https://rollupjs.org), pre-configured to output highly optimized static assets for production.
+
+In addition, Vite is highly extensible via its [Plugin API](https://vitejs.dev/guide/api-plugin.html) and [JavaScript API](https://vitejs.dev/guide/api-javascript.html) with full typing support.
+
+[Read the Docs to Learn More](https://vitejs.dev).

+// The following three functions all verify that a node is an lvalue —

+// a variety of checks:
+//
+// - Check that none of the bound/assigned-to identifiers are reserved words.
+// - Record name declarations for bindings in the appropriate scope.
+// - Check duplicate argument names, if checkClashes is set.
+//
+// If a complex binding pattern is encountered (e.g., object and array
+// destructuring), the entire pattern is recursively checked.
+//
+// There are three versions of checkLVal*() appropriate for different
+// circumstances:
+//
+// - checkLValSimple() shall be used if the syntactic construct supports
+//   nothing other than identifiers and member expressions. Parenthesized
+//   expressions are also correctly handled. This is generally appropriate for
+//   constructs for which the spec says
+//
+//   > It is a Syntax Error if AssignmentTargetType of [the production] is not
+//   > simple.
+//
+//   It is also appropriate for checking if an identifier is valid and not
+//   defined elsewhere, like import declarations or function/class identifiers.
+//
+//   Examples where this is used include:
+//     a += …;
+//     import a from '…';
+//   where a is the node to be checked.
+//
+// - checkLValPattern() shall be used if the syntactic construct supports
+//   anything checkLValSimple() supports, as well as object and array
+//   destructuring patterns. This is generally appropriate for constructs for
+//   which the spec says
+//
+//   > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
+//   > an ArrayLiteral and AssignmentTargetType of [the production] is not
+//   > simple.
+//
+//   Examples where this is used include:
+//     (a = …);
+//     const a = …;
+//     try { … } catch (a) { … }
+//   where a is the node to be checked.
+//
+// - checkLValInnerPattern() shall be used if the syntactic construct supports
+//   anything checkLValPattern() supports, as well as default assignment
+//   patterns, rest elements, and other constructs that may appear within an
+//   object or array destructuring pattern.
+//
+//   As a special case, function parameters also use checkLValInnerPattern(),
+//   as they also support defaults and rest constructs.
+//
+// These functions deliberately support both assignment and binding constructs,
+// as the logic for both is exceedingly similar. If the node is the target of
+// an assignment, then bindingType should be set to BIND_NONE. Otherwise, it
+// should be set to the appropriate BIND_* constant, like BIND_VAR or
+// BIND_LEXICAL.
+//
+// If the function is called with a non-BIND_NONE bindingType, then

+ *   - `key`: For sequence values and map `Pair`, the node's index in the
+ *     collection. Within a `Pair`, `'key'` or `'value'`, correspondingly.
+ *     `null` for the root node.
+ *   - `node`: The current node.
+ *   - `path`: The ancestry of the current node.
+ *
+ * The return value of the visitor may be used to control the traversal:
+ *   - `undefined` (default): Do nothing and continue
+ *   - `visit.SKIP`: Do not visit the children of this node, continue with next
+ *     sibling
+ *   - `visit.BREAK`: Terminate traversal completely
+ *   - `visit.REMOVE`: Remove the current node, then continue with the next one
+ *   - `Node`: Replace the current node, then continue by visiting it
+ *   - `number`: While iterating the items of a sequence or map, set the index
+ *     of the next step. This is useful especially if the index of the current
+ *     node has changed.
+ *
+ * If `visitor` is a single function, it will be called with all values
+ * encountered in the tree, including e.g. `null` values. Alternatively,
+ * separate visitor functions may be defined for each `Map`, `Pair`, `Seq`,
+ * `Alias` and `Scalar` node. To define the same visitor function for more than
+ * one node type, use the `Collection` (map and seq), `Value` (map, seq & scalar)
+ * and `Node` (alias, map, seq & scalar) targets. Of all these, only the most
+ * specific defined one will be used for each node.

+/**
+ * Apply an async visitor to an AST node or document.
+ *
+ * Walks through the tree (depth-first) starting from `node`, calling a
+ * `visitor` function with three arguments:
+ *   - `key`: For sequence values and map `Pair`, the node's index in the
+ *     collection. Within a `Pair`, `'key'` or `'value'`, correspondingly.
+ *     `null` for the root node.
+ *   - `node`: The current node.
+ *   - `path`: The ancestry of the current node.
+ *
+ * The return value of the visitor may be used to control the traversal:
+ *   - `Promise`: Must resolve to one of the following values
+ *   - `undefined` (default): Do nothing and continue
+ *   - `visit.SKIP`: Do not visit the children of this node, continue with next
+ *     sibling
+ *   - `visit.BREAK`: Terminate traversal completely
+ *   - `visit.REMOVE`: Remove the current node, then continue with the next one
+ *   - `Node`: Replace the current node, then continue by visiting it
+ *   - `number`: While iterating the items of a sequence or map, set the index
+ *     of the next step. This is useful especially if the index of the current
+ *     node has changed.
+ *
+ * If `visitor` is a single function, it will be called with all values
+ * encountered in the tree, including e.g. `null` values. Alternatively,
+ * separate visitor functions may be defined for each `Map`, `Pair`, `Seq`,
+ * `Alias` and `Scalar` node. To define the same visitor function for more than
+ * one node type, use the `Collection` (map and seq), `Value` (map, seq & scalar)
+ * and `Node` (alias, map, seq & scalar) targets. Of all these, only the most
+ * specific defined one will be used for each node.

+     *
+     * // output
+     * import * as foo from 'foo';
+     * ```
+     *
+     * However, there are some situations where this may not be desired.
+     * For these situations, you can change Rollup's behaviour either globally or
+     * per module. To change it globally, set the `requireReturnsDefault` option
+     * to one of the following values:
+     *
+     * - `false`: This is the default, requiring an ES module returns its
+     *   namespace. This is the only option that will also add a marker
+     *   `__esModule: true` to the namespace to support interop patterns in
+     *   CommonJS modules that are transpiled ES modules.
+     * - `"namespace"`: Like `false`, requiring an ES module returns its
+     *   namespace, but the plugin does not add the `__esModule` marker and thus
+     *   creates more efficient code. For external dependencies when using
+     *   `esmExternals: true`, no additional interop code is generated.
+     * - `"auto"`: This is complementary to how `output.exports: "auto"` works in
+     *   Rollup: If a module has a default export and no named exports, requiring
+     *   that module returns the default export. In all other cases, the namespace
+     *   is returned. For external dependencies when using `esmExternals: true`, a
+     *   corresponding interop helper is added.
+     * - `"preferred"`: If a module has a default export, requiring that module
+     *   always returns the default export, no matter whether additional named
+     *   exports exist. This is similar to how previous versions of this plugin
+     *   worked. Again for external dependencies when using `esmExternals: true`,
+     *   an interop helper is added.
+     * - `true`: This will always try to return the default export on require
+     *   without checking if it actually exists. This can throw at build time if
+     *   there is no default export. This is how external dependencies are handled
+     *   when `esmExternals` is not used. The advantage over the other options is
+     *   that, like `false`, this does not add an interop helper for external
+     *   dependencies, keeping the code lean.
+     *
+     * To change this for individual modules, you can supply a function for
+     * `requireReturnsDefault` instead. This function will then be called once for
+     * each required ES module or external dependency with the corresponding id

+(libsodium), a core extension in PHP 7.2.0+ and otherwise [available in PECL](https://pecl.php.net/package/libsodium).
+
+This library tentatively supports PHP 5.2.4 - 8.x (latest), but officially
+only supports [non-EOL'd versions of PHP](https://secure.php.net/supported-versions.php).
+
+If you have the PHP extension installed, Sodium Compat will opportunistically
+and transparently use the PHP extension instead of our implementation.
+
+## IMPORTANT!
+
+This cryptography library has not been formally audited by an independent third 
+party that specializes in cryptography or cryptanalysis.
+
+If you require such an audit before you can use sodium_compat in your projects
+and have the funds for such an audit, please open an issue or contact 
+`security at paragonie dot com` so we can help get the ball rolling.
+
+However, sodium_compat has been adopted by high profile open source projects,
+such as [Joomla!](https://github.com/joomla/joomla-cms/blob/459d74686d2a638ec51149d7c44ddab8075852be/composer.json#L40)
+and [Magento](https://github.com/magento/magento2/blob/8fd89cfdf52c561ac0ca7bc20fd38ef688e201b0/composer.json#L44).
+Furthermore, sodium_compat was developed by Paragon Initiative Enterprises, a
+company that *specializes* in secure PHP development and PHP cryptography, and
+has been informally reviewed by many other security experts who also specialize
+in PHP.
+
+If you'd like to learn more about the defensive security measures we've taken
+to prevent sodium_compat from being a source of vulnerability in your systems,
+please read [*Cryptographically Secure PHP Development*](https://paragonie.com/blog/2017/02/cryptographically-secure-php-development).
+
+# Installing Sodium Compat
+
+If you're using Composer:
+
+```bash
+composer require paragonie/sodium_compat
+```
+
+### Install From Source
+
+If you're not using Composer, download a [release tarball](https://github.com/paragonie/sodium_compat/releases)
+(which should be signed with [our GnuPG public key](https://paragonie.com/static/gpg-public-key.txt)), extract
+its contents, then include our `autoload.php` script in your project.
+
+```php
+<?php
+require_once "/path/to/sodium_compat/autoload.php";
+```
+
+### PHP Archives (Phar) Releases
+
+Since version 1.3.0, [sodium_compat releases](https://github.com/paragonie/sodium_compat/releases) include a
+PHP Archive (.phar file) and associated GPG signature. First, download both files and verify them with our
+GPG public key, like so:
+
+```bash
+# Getting our public key from the keyserver:
+gpg --fingerprint 7F52D5C61D1255C731362E826B97A1C2826404DA
+if [ $? -ne 0 ]; then
+    echo -e "\033[33mDownloading PGP Public Key...\033[0m"
+    gpg  --keyserver pgp.mit.edu --recv-keys 7F52D5C61D1255C731362E826B97A1C2826404DA
+    # Security <security@paragonie.com>
+    gpg --fingerprint 7F52D5C61D1255C731362E826B97A1C2826404DA
+    if [ $? -ne 0 ]; then
+        echo -e "\033[31mCould not download PGP public key for verification\033[0m"
+        exit 1
+    fi
+fi
+
+# Verifying the PHP Archive
+gpg --verify sodium-compat.phar.sig sodium-compat.phar
+```
+
+Now, simply include this .phar file in your application.
+
+```php
+<?php
+require_once "/path/to/sodium-compat.phar";
+```
+
+# Support
+
+[Commercial support for libsodium](https://download.libsodium.org/doc/commercial_support/) is available
+from multiple vendors. If you need help using sodium_compat in one of your projects, [contact Paragon Initiative Enterprises](https://paragonie.com/contact). 
+
+Non-commercial report will be facilitated through [Github issues](https://github.com/paragonie/sodium_compat/issues).
+We offer no guarantees of our availability to resolve questions about integrating sodium_compat into third-party
+software for free, but will strive to fix any bugs (security-related or otherwise) in our library.
+
+## Support Contracts
+
+If your company uses this library in their products or services, you may be
+interested in [purchasing a support contract from Paragon Initiative Enterprises](https://paragonie.com/enterprise).
+
+# Using Sodium Compat
+
+## True Polyfill
+
+As per the [second vote on the libsodium RFC](https://wiki.php.net/rfc/libsodium#proposed_voting_choices),
+PHP 7.2 uses `sodium_*` instead of `\Sodium\*`.
+
+```php
+<?php
+require_once "/path/to/sodium_compat/autoload.php";
+
+$alice_kp = sodium_crypto_sign_keypair();
+$alice_sk = sodium_crypto_sign_secretkey($alice_kp);
+$alice_pk = sodium_crypto_sign_publickey($alice_kp);
+
+$message = 'This is a test message.';
+$signature = sodium_crypto_sign_detached($message, $alice_sk);
+if (sodium_crypto_sign_verify_detached($signature, $message, $alice_pk)) {
+    echo 'OK', PHP_EOL;
+} else {
+    throw new Exception('Invalid signature');
+}
+```
+
+## Polyfill For the Old PECL Extension API
+
+If you're using PHP 5.3.0 or newer and do not have the PECL extension installed,
+you can just use the [standard ext/sodium API features as-is](https://paragonie.com/book/pecl-libsodium)
+and the polyfill will work its magic.
+
+```php
+<?php
+require_once "/path/to/sodium_compat/autoload.php";
+
+$alice_kp = \Sodium\crypto_sign_keypair();
+$alice_sk = \Sodium\crypto_sign_secretkey($alice_kp);
+$alice_pk = \Sodium\crypto_sign_publickey($alice_kp);
+
+$message = 'This is a test message.';
+$signature = \Sodium\crypto_sign_detached($message, $alice_sk);
+if (\Sodium\crypto_sign_verify_detached($signature, $message, $alice_pk)) {
+    echo 'OK', PHP_EOL;
+} else {
+    throw new Exception('Invalid signature');
+}
+```
+
+The polyfill does not expose this API on PHP < 5.3, or if you have the PHP
+extension installed already.
+
+## General-Use Polyfill
+
+If your users are on PHP < 5.3, or you want to write code that will work
+whether or not the PECL extension is available, you'll want to use the
+**`ParagonIE_Sodium_Compat`** class for most of your libsodium needs.
+
+The above example, written for general use:
+
+```php
+<?php
+require_once "/path/to/sodium_compat/autoload.php";
+
+$alice_kp = ParagonIE_Sodium_Compat::crypto_sign_keypair();
+$alice_sk = ParagonIE_Sodium_Compat::crypto_sign_secretkey($alice_kp);
+$alice_pk = ParagonIE_Sodium_Compat::crypto_sign_publickey($alice_kp);
+
+$message = 'This is a test message.';
+$signature = ParagonIE_Sodium_Compat::crypto_sign_detached($message, $alice_sk);
+if (ParagonIE_Sodium_Compat::crypto_sign_verify_detached($signature, $message, $alice_pk)) {
+    echo 'OK', PHP_EOL;
+} else {
+    throw new Exception('Invalid signature');
+}
+```
+
+Generally: If you replace `\Sodium\ ` with `ParagonIE_Sodium_Compat::`, any
+code already written for the libsodium PHP extension should work with our
+polyfill without additional code changes.
+
+Since this doesn't require a namespace, this API *is* exposed on PHP 5.2.
+
+Since version 0.7.0, we have our own namespaced API (`ParagonIE\Sodium\*`) to allow brevity
+in software that uses PHP 5.3+. This is useful if you want to use our file cryptography
+features without writing `ParagonIE_Sodium_File` every time. This is not exposed on PHP < 5.3,
+so if your project supports PHP < 5.3, use the underscore method instead.
+
+To learn how to use Libsodium, read [*Using Libsodium in PHP Projects*](https://paragonie.com/book/pecl-libsodium).
+
+## Help, Sodium_Compat is Slow! How can I make it fast?
+
+There are three ways to make it fast:
+
+1. Use a newer version of PHP (at least 7.2).
+2. [Install the libsodium PHP extension from PECL](https://paragonie.com/book/pecl-libsodium/read/00-intro.md#installing-libsodium).
+3. Only if the previous two options are not available for you:
+   1. Verify that [the processor you're using actually implements constant-time multiplication](https://bearssl.org/ctmul.html).
+      Sodium_compat does, but it must trade some speed in order to attain cross-platform security.
+   2. Only if you are 100% certain that your processor is safe, you can set `ParagonIE_Sodium_Compat::$fastMult = true;`
+      without harming the security of your cryptography keys. If your processor *isn't* safe, then decide whether you
+      want speed or security because you can't have both.
+
+### How can I tell if sodium_compat will be slow, at runtime?
+
+Since version 1.8, you can use the `polyfill_is_fast()` static method to
+determine if sodium_compat will be slow at runtime.
+
+```php
+<?php
+if (ParagonIE_Sodium_Compat::polyfill_is_fast()) {
+    // Use libsodium now
+    $process->execute();
+} else {
+    // Defer to a cron job or other sort of asynchronous process
+    $process->enqueue();
+}
+```
+
+### Help, my PHP only has 32-Bit Integers! It's super slow!
+
+If the `PHP_INT_SIZE` constant equals `4` instead of `8` (PHP 5 on Windows,
+Linux on i386, etc.), you will run into **significant performance issues**.
+
+In particular: public-key cryptography (encryption and signatures)
+is affected. There is nothing we can do about that.
+
+The root cause of these performance issues has to do with implementing cryptography
+algorithms in constant-time using 16-bit limbs (to avoid overflow) in pure PHP.
+
+To mitigate these performance issues, simply install PHP 7.2 or newer and enable
+the `sodium` extension.
+
+Affected users are encouraged to install the sodium extension (or libsodium from
+older version of PHP).
+
+Windows users on PHP 5 may be able to simply upgrade to PHP 7 and the slowdown
+will be greatly reduced.
+
+## Documentation
+
+First, you'll want to read the [Libsodium Quick Reference](https://paragonie.com/blog/2017/06/libsodium-quick-reference-quick-comparison-similar-functions-and-which-one-use).
+It aims to answer, "Which function should I use for [common problem]?".
+
+If you don't find the answers in the Quick Reference page, check out
+[*Using Libsodium in PHP Projects*](https://paragonie.com/book/pecl-libsodium).
+
+Finally, the [official libsodium documentation](https://download.libsodium.org/doc/) 
+(which was written for the C library, not the PHP library) also contains a lot of
+insightful technical information you may find helpful.

+### Cryptography Primitives Provided
+
+* **X25519** - Elliptic Curve Diffie Hellman over Curve25519
+* **Ed25519** - Edwards curve Digital Signature Algorithm over Curve25519
+* **Xsalsa20** - Extended-nonce Salsa20 stream cipher
+* **ChaCha20** - Stream cipher
+* **Xchacha20** - Extended-nonce ChaCha20 stream cipher
+* **Poly1305** - Polynomial Evaluation Message Authentication Code modulo 2^130 - 5
+* **BLAKE2b** - Cryptographic Hash Function
+* **SipHash-2-4** - Fast hash, but not collision-resistant; ideal for hash tables.
+
+### Features Excluded from this Polyfill
+
+* `\Sodium\memzero()` - Although we expose this API endpoint, we can't reliably
+  zero buffers from PHP.
+  
+  If you have the PHP extension installed, sodium_compat
+  will use the native implementation to zero out the string provided. Otherwise
+  it will throw a `SodiumException`.
+* `\Sodium\crypto_pwhash()` - It's not feasible to polyfill scrypt or Argon2
+  into PHP and get reasonable performance. Users would feel motivated to select
+  parameters that downgrade security to avoid denial of service (DoS) attacks.
+  
+  The only winning move is not to play.
+  
+  If ext/sodium or ext/libsodium is installed, these API methods will fallthrough
+  to the extension. Otherwise, our polyfill library will throw a `SodiumException`.
+  
+  To detect support for Argon2i at runtime, use
+  `ParagonIE_Sodium_Compat::crypto_pwhash_is_available()`, which returns a
+   boolean value (`TRUE` or `FALSE`).
+
+### PHPCompatibility Ruleset
+
+For sodium_compat users and that utilize [`PHPCompatibility`](https://github.com/PHPCompatibility/PHPCompatibility)
+in their CI process, there is now a custom ruleset available which can be used
+to prevent false positives being thrown by `PHPCompatibility` for the native
+PHP functionality being polyfilled by this repo.
+
+You can find the repo for the `PHPCompatibilityParagonieSodiumCompat` ruleset
+here [on Github](https://github.com/PHPCompatibility/PHPCompatibilityParagonie) 
+and [on Packagist](https://packagist.org/packages/phpcompatibility/phpcompatibility-paragonie).

+ * Libsodium compatibility layer
+ *
+ * This is the only class you should be interfacing with, as a user of
+ * sodium_compat.
+ *
+ * If the PHP extension for libsodium is installed, it will always use that
+ * instead of our implementations. You get better performance and stronger
+ * guarantees against side-channels that way.
+ *
+ * However, if your users don't have the PHP extension installed, we offer a
+ * compatible interface here. It will give you the correct results as if the
+ * PHP extension was installed. It won't be as fast, of course.
+ *
