+## About Laravel
+
+Laravel is a web application framework with expressive, elegant syntax. We believe development must be an enjoyable and creative experience to be truly fulfilling. Laravel takes the pain out of development by easing common tasks used in many web projects, such as:
+
+- [Simple, fast routing engine](https://laravel.com/docs/routing).
+- [Powerful dependency injection container](https://laravel.com/docs/container).
+- Multiple back-ends for [session](https://laravel.com/docs/session) and [cache](https://laravel.com/docs/cache) storage.
+- Expressive, intuitive [database ORM](https://laravel.com/docs/eloquent).
+- Database agnostic [schema migrations](https://laravel.com/docs/migrations).
+- [Robust background job processing](https://laravel.com/docs/queues).
+- [Real-time event broadcasting](https://laravel.com/docs/broadcasting).
+
+Laravel is accessible, powerful, and provides tools required for large, robust applications.
+
+## Learning Laravel
+
+Laravel has the most extensive and thorough [documentation](https://laravel.com/docs) and video tutorial library of all modern web application frameworks, making it a breeze to get started with the framework.
+
+If you don't feel like reading, [Laracasts](https://laracasts.com) can help. Laracasts contains over 1500 video tutorials on a range of topics including Laravel, modern PHP, unit testing, and JavaScript. Boost your skills by digging into our comprehensive video library.

+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+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 accepts
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+base64id
+========
+
+Node.js module that generates a base64 id.
+
+Uses crypto.randomBytes when available, falls back to unsafe methods for node.js <= 0.4.
+
+To increase performance, random bytes are buffered to minimize the number of synchronous calls to crypto.randomBytes.
+
+## Installation
+
+   $ npm install base64id
+
+## Usage
+
+   var base64id = require('base64id');
+
+   var id = base64id.generateId();

+# Emitter [![Build Status](https://travis-ci.org/component/emitter.png)](https://travis-ci.org/component/emitter)
+
+  Event emitter component.
+
+## Installation
+
+```
+$ component install component/emitter
+```
+
+## API
+
+### Emitter(obj)
+
+  The `Emitter` may also be used as a mixin. For example
+  a "plain" object may become an emitter, or you may
+  extend an existing prototype.
+
+  As an `Emitter` instance:
+
+```js
+var Emitter = require('emitter');
+var emitter = new Emitter;
+emitter.emit('something');
+```
+
+  As a mixin:
+
+```js
+var Emitter = require('emitter');
+var user = { name: 'tobi' };
+Emitter(user);
+
+user.emit('im a user');
+```
+
+  As a prototype mixin:
+
+```js
+var Emitter = require('emitter');
+Emitter(User.prototype);
+```
+
+### Emitter#on(event, fn)
+
+  Register an `event` handler `fn`.
+
+### Emitter#once(event, fn)
+
+  Register a single-shot `event` handler `fn`,
+  removed immediately after it is invoked the
+  first time.
+
+### Emitter#off(event, fn)
+
+  * Pass `event` and `fn` to remove a listener.
+  * Pass `event` to remove all listeners on that event.
+  * Pass nothing to remove all listeners on all events.
+
+### Emitter#emit(event, ...)
+
+  Emit an `event` with variable option args.
+
+### Emitter#listeners(event)
+
+  Return an array of callbacks, or an empty array.
+
+### Emitter#hasListeners(event)
+
+  Check if this emitter has `event` handlers.

+
+Basic HTTP cookie parser and serializer for HTTP servers.
+
+## Installation
+
+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 cookie
+```
+
+## API
+
+```js
+var cookie = require('cookie');
+```
+
+### cookie.parse(str, options)
+
+Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs.
+The `str` argument is the string representing a `Cookie` header value and `options` is an
+optional object containing additional parsing options.
+
+```js
+var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2');
+// { foo: 'bar', equation: 'E=mc^2' }
+```
+
+#### Options
+
+`cookie.parse` accepts these properties in the options object.
+
+##### decode
+
+Specifies a function that will be used to decode a cookie's value. Since the value of a cookie
+has a limited character set (and must be a simple string), this function can be used to decode
+a previously-encoded cookie value into a JavaScript string or other object.
+
+The default function is the global `decodeURIComponent`, which will decode any URL-encoded
+sequences into their byte representations.
+
+**note** if an error is thrown from this function, the original, non-decoded cookie value will
+be returned as the cookie's value.
+
+### cookie.serialize(name, value, options)
+
+Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the
+name for the cookie, the `value` argument is the value to set the cookie to, and the `options`
+argument is an optional object containing additional serialization options.
+
+```js
+var setCookie = cookie.serialize('foo', 'bar');
+// foo=bar
+```
+
+#### Options
+
+`cookie.serialize` accepts these properties in the options object.
+
+##### domain
+
+Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6265-5.2.3]. By default, no
+domain is set, and most clients will consider the cookie to apply to only the current domain.
+
+##### encode
+
+Specifies a function that will be used to encode a cookie's value. Since value of a cookie
+has a limited character set (and must be a simple string), this function can be used to encode
+a value into a string suited for a cookie's value.
+
+The default function is the global `encodeURIComponent`, which will encode a JavaScript string
+into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range.
+
+##### expires
+
+Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6265-5.2.1].
+By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and
+will delete it on a condition like exiting a web browser application.
+
+**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
+`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### httpOnly
+
+Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6265-5.2.6]. When truthy,
+the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not allow client-side
+JavaScript to see the cookie in `document.cookie`.
+
+##### maxAge
+
+Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6265-5.2.2].
+The given number will be converted to an integer by rounding down. By default, no maximum age is set.
+
+**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
+`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### path
+
+Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6265-5.2.4]. By default, the path
+is considered the ["default path"][rfc-6265-5.1.4].
+
+##### sameSite
+
+Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-03-4.1.2.7].
+
+  - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+  - `false` will not set the `SameSite` attribute.
+  - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
+  - `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie.
+  - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+
+More information about the different enforcement levels can be found in
+[the specification][rfc-6265bis-03-4.1.2.7].
+
+**note** This is an attribute that has not yet been fully standardized, and may change in the future.
+This also means many clients may ignore this attribute until they understand it.
+
+##### secure
+
+Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6265-5.2.5]. When truthy,
+the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to
+the server in the future if the browser does not have an HTTPS connection.
+
+## Example
+
+The following example uses this module in conjunction with the Node.js core HTTP server
+to prompt a user for their name and display it back on future visits.
+
+```js
+var cookie = require('cookie');
+var escapeHtml = require('escape-html');
+var http = require('http');
+var url = require('url');
+
+function onRequest(req, res) {
+  // Parse the query string
+  var query = url.parse(req.url, true, true).query;
+
+  if (query && query.name) {
+    // Set a new cookie with the name
+    res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), {
+      httpOnly: true,
+      maxAge: 60 * 60 * 24 * 7 // 1 week
+    }));
+
+    // Redirect back after setting cookie
+    res.statusCode = 302;
+    res.setHeader('Location', req.headers.referer || '/');
+    res.end();
+    return;
+  }
+
+  // Parse the cookies on the request
+  var cookies = cookie.parse(req.headers.cookie || '');
+
+  // Get the visitor name set in the cookie
+  var name = cookies.name;
+
+  res.setHeader('Content-Type', 'text/html; charset=UTF-8');
+
+  if (name) {
+    res.write('<p>Welcome back, <b>' + escapeHtml(name) + '</b>!</p>');
+  } else {
+    res.write('<p>Hello, new visitor!</p>');
+  }
+
+  res.write('<form method="GET">');
+  res.write('<input placeholder="enter your name" name="name"> <input type="submit" value="Set Name">');
+  res.end('</form>');
+}
+
+http.createServer(onRequest).listen(3000);

+
+## Installation
+
+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 cors
+```
+
+## Usage
+
+### Simple Usage (Enable *All* CORS Requests)
+
+```javascript
+var express = require('express')
+var cors = require('cors')
+var app = express()
+
+app.use(cors())
+
+app.get('/products/:id', function (req, res, next) {
+  res.json({msg: 'This is CORS-enabled for all origins!'})
+})
+
+app.listen(80, function () {
+  console.log('CORS-enabled web server listening on port 80')
+})
+```
+
+### Enable CORS for a Single Route
+
+```javascript
+var express = require('express')
+var cors = require('cors')
+var app = express()
+
+app.get('/products/:id', cors(), function (req, res, next) {
+  res.json({msg: 'This is CORS-enabled for a Single Route'})
+})
+
+app.listen(80, function () {
+  console.log('CORS-enabled web server listening on port 80')
+})
+```
+
+### Configuring CORS
+
+```javascript
+var express = require('express')
+var cors = require('cors')
+var app = express()
+
+var corsOptions = {
+  origin: 'http://example.com',
+  optionsSuccessStatus: 200 // some legacy browsers (IE11, various SmartTVs) choke on 204
+}
+
+app.get('/products/:id', cors(corsOptions), function (req, res, next) {
+  res.json({msg: 'This is CORS-enabled for only example.com.'})
+})
+
+app.listen(80, function () {
+  console.log('CORS-enabled web server listening on port 80')
+})
+```
+
+### Configuring CORS w/ Dynamic Origin
+
+```javascript
+var express = require('express')
+var cors = require('cors')
+var app = express()
+
+var whitelist = ['http://example1.com', 'http://example2.com']
+var corsOptions = {
+  origin: function (origin, callback) {
+    if (whitelist.indexOf(origin) !== -1) {
+      callback(null, true)
+    } else {
+      callback(new Error('Not allowed by CORS'))
+    }
+  }
+}
+
+app.get('/products/:id', cors(corsOptions), function (req, res, next) {
+  res.json({msg: 'This is CORS-enabled for a whitelisted domain.'})
+})
+
+app.listen(80, function () {
+  console.log('CORS-enabled web server listening on port 80')
+})
+```
+
+If you do not want to block REST tools or server-to-server requests,
+add a `!origin` check in the origin function like so:
+
+```javascript
+var corsOptions = {
+  origin: function (origin, callback) {
+    if (whitelist.indexOf(origin) !== -1 || !origin) {
+      callback(null, true)
+    } else {
+      callback(new Error('Not allowed by CORS'))
+    }
+  }
+}
+```
+
+### Enabling CORS Pre-Flight
+
+Certain CORS requests are considered 'complex' and require an initial
+`OPTIONS` request (called the "pre-flight request"). An example of a
+'complex' CORS request is one that uses an HTTP verb other than
+GET/HEAD/POST (such as DELETE) or that uses custom headers. To enable
+pre-flighting, you must add a new OPTIONS handler for the route you want
+to support:
+
+```javascript
+var express = require('express')
+var cors = require('cors')
+var app = express()
+
+app.options('/products/:id', cors()) // enable pre-flight request for DELETE request
+app.del('/products/:id', cors(), function (req, res, next) {
+  res.json({msg: 'This is CORS-enabled for all origins!'})
+})
+
+app.listen(80, function () {
+  console.log('CORS-enabled web server listening on port 80')
+})
+```
+
+You can also enable pre-flight across-the-board like so:
+
+```javascript
+app.options('*', cors()) // include before other routes
+```
+
+### Configuring CORS Asynchronously
+
+```javascript
+var express = require('express')
+var cors = require('cors')
+var app = express()
+
+var whitelist = ['http://example1.com', 'http://example2.com']
+var corsOptionsDelegate = function (req, callback) {
+  var corsOptions;
+  if (whitelist.indexOf(req.header('Origin')) !== -1) {
+    corsOptions = { origin: true } // reflect (enable) the requested origin in the CORS response
+  } else {
+    corsOptions = { origin: false } // disable CORS for this request
+  }
+  callback(null, corsOptions) // callback expects two parameters: error and options
+}
+
+app.get('/products/:id', cors(corsOptionsDelegate), function (req, res, next) {
+  res.json({msg: 'This is CORS-enabled for a whitelisted domain.'})
+})
+
+app.listen(80, function () {
+  console.log('CORS-enabled web server listening on port 80')
+})
+```
+
+## Configuration Options
+
+* `origin`: Configures the **Access-Control-Allow-Origin** CORS header. Possible values:
+  - `Boolean` - set `origin` to `true` to reflect the [request origin](http://tools.ietf.org/html/draft-abarth-origin-09), as defined by `req.header('Origin')`, or set it to `false` to disable CORS.
+  - `String` - set `origin` to a specific origin. For example if you set it to `"http://example.com"` only requests from "http://example.com" will be allowed.
+  - `RegExp` - set `origin` to a regular expression pattern which will be used to test the request origin. If it's a match, the request origin will be reflected. For example the pattern `/example\.com$/` will reflect any request that is coming from an origin ending with "example.com".
+  - `Array` - set `origin` to an array of valid origins. Each origin can be a `String` or a `RegExp`. For example `["http://example1.com", /\.example2\.com$/]` will accept any request from "http://example1.com" or from a subdomain of "example2.com".
+  - `Function` - set `origin` to a function implementing some custom logic. The function takes the request origin as the first parameter and a callback (which expects the signature `err [object], allow [bool]`) as the second.
+* `methods`: Configures the **Access-Control-Allow-Methods** CORS header. Expects a comma-delimited string (ex: 'GET,PUT,POST') or an array (ex: `['GET', 'PUT', 'POST']`).
+* `allowedHeaders`: Configures the **Access-Control-Allow-Headers** CORS header. Expects a comma-delimited string (ex: 'Content-Type,Authorization') or an array (ex: `['Content-Type', 'Authorization']`). If not specified, defaults to reflecting the headers specified in the request's **Access-Control-Request-Headers** header.
+* `exposedHeaders`: Configures the **Access-Control-Expose-Headers** CORS header. Expects a comma-delimited string (ex: 'Content-Range,X-Content-Range') or an array (ex: `['Content-Range', 'X-Content-Range']`). If not specified, no custom headers are exposed.
+* `credentials`: Configures the **Access-Control-Allow-Credentials** CORS header. Set to `true` to pass the header, otherwise it is omitted.
+* `maxAge`: Configures the **Access-Control-Max-Age** CORS header. Set to an integer to pass the header, otherwise it is omitted.
+* `preflightContinue`: Pass the CORS preflight response to the next handler.
+* `optionsSuccessStatus`: Provides a status code to use for successful `OPTIONS` requests, since some legacy browsers (IE11, various SmartTVs) choke on `204`.
+
+The default configuration is the equivalent of:
+
+```json
+{
+  "origin": "*",
+  "methods": "GET,HEAD,PUT,PATCH,POST,DELETE",
+  "preflightContinue": false,
+  "optionsSuccessStatus": 204
+}
+```
+
+For details on the effect of each CORS header, read [this](http://www.html5rocks.com/en/tutorials/cors/) article on HTML5 Rocks.

+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+  , b = require('debug')('worker:b');
+
+function work() {
+  a('doing lots of uninteresting work');
+  setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+  b('doing some work');
+  setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">

+
+#### Windows command prompt notes
+
+##### CMD
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Example:
+
+```cmd
+set DEBUG=* & node app.js
+```
+
+##### PowerShell (VS Code default)
+
+PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Example:
+
+```cmd
+$env:DEBUG='app';node app.js
+```
+
+Then, run the program to be debugged as usual.
+
+npm script example:
+```js
+  "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
+```
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".  If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable.  You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name      | Purpose                                         |
+|-----------|-------------------------------------------------|
+| `DEBUG`   | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY).  |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth.                    |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O`      | Pretty-print an Object on multiple lines. |
+| `%o`      | Pretty-print an Object all on a single line. |
+| `%s`      | String. |
+| `%d`      | Number (both integer and float). |
+| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%`      | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+  return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Extend
+You can simply extend debugger 
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');
+
+log('hello'); // auth hello
+logSign('hello'); //auth:sign hello
+logLogin('hello'); //auth:login hello
+```
+
+## Set dynamically
+
+You can also enable debug dynamically by calling the `enable()` method :
+
+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));
+
+debug.disable();
+console.log(3, debug.enabled('test'));
+
+```
+
+print :   
+```
+1 false
+2 true
+3 false
+```
+
+Usage :  
+`enable(namespaces)`  
+`namespaces` can include modes separated by a colon and wildcards.
+   
+Note that calling `enable()` completely overrides previously set DEBUG variable : 
+
+```
+$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
+=> false
+```
+
+`disable()`
+
+Will disable all namespaces. The functions returns the namespaces currently
+enabled (and skipped). This can be useful if you want to disable debugging
+temporarily without knowing what was enabled to begin with.
+
+For example:
+
+```js
+let debug = require('debug');
+debug.enable('foo:*,-foo:bar');
+let namespaces = debug.disable();
+debug.enable(namespaces);
+```
+
+Note: There is no guarantee that the string will be identical to the initial
+enable string, but semantically they will be identical.
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+  // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+## [4.0.1](https://github.com/socketio/engine.io-parser/compare/4.0.0...4.0.1) (2020-09-10)
+
+
+### Bug Fixes
+
+* use a terser-compatible representation of the separator ([886f9ea](https://github.com/socketio/engine.io-parser/commit/886f9ea7c4e717573152c31320f6fb6c6664061b))
+
+
+# [4.0.0](https://github.com/socketio/engine.io-parser/compare/v4.0.0-alpha.1...4.0.0) (2020-09-08)
+
+This major release contains the necessary changes for the version 4 of the Engine.IO protocol. More information about the new version can be found [there](https://github.com/socketio/engine.io-protocol#difference-between-v3-and-v4).
+
+Encoding changes between v3 and v4:
+
+- encodePacket with string
+  - input: `{ type: "message", data: "hello" }`
+  - output in v3: `"4hello"`
+  - output in v4: `"4hello"`
+
+- encodePacket with binary
+  - input: `{ type: 'message', data: <Buffer 01 02 03> }`
+  - output in v3: `<Buffer 04 01 02 03>`
+  - output in v4: `<Buffer 01 02 03>`
+
+- encodePayload with strings
+  - input: `[ { type: 'message', data: 'hello' }, { type: 'message', data: '€€€' } ]`
+  - output in v3: `"6:4hello4:4€€€"`
+  - output in v4: `"4hello\x1e4€€€"`
+
+- encodePayload with string and binary
+  - input: `[ { type: 'message', data: 'hello' }, { type: 'message', data: <Buffer 01 02 03> } ]`
+  - output in v3: `<Buffer 00 06 ff 34 68 65 6c 6c 6f 01 04 ff 04 01 02 03>`
+  - output in v4: `"4hello\x1ebAQID"`
+
+Please note that the parser is now dependency-free! This should help reduce the size of the browser bundle.
+
+### Bug Fixes
+
+* keep track of the buffer initial length ([8edf2d1](https://github.com/socketio/engine.io-parser/commit/8edf2d1478026da442f519c2d2521af43ba01832))
+
+
+### Features
+
+* restore the upgrade mechanism ([6efedfa](https://github.com/socketio/engine.io-parser/commit/6efedfa0f3048506a4ba99e70674ddf4c0732e0c))
+
+
+
+# [4.0.0-alpha.1](https://github.com/socketio/engine.io-parser/compare/v4.0.0-alpha.0...v4.0.0-alpha.1) (2020-05-19)
+
+
+### Features
+
+* implement the version 4 of the protocol ([cab7db0](https://github.com/socketio/engine.io-parser/commit/cab7db0404e0a69f86a05ececd62c8c31f4d97d5))
+
+
+
+# [4.0.0-alpha.0](https://github.com/socketio/engine.io-parser/compare/2.2.0...v4.0.0-alpha.0) (2020-02-04)
+
+
+### Bug Fixes
+
+* properly decode binary packets ([5085373](https://github.com/socketio/engine.io-parser/commit/50853738e0c6c16f9cee0d7887651155f4b78240))
+
+
+### Features
+
+* remove packet type when encoding binary packets ([a947ae5](https://github.com/socketio/engine.io-parser/commit/a947ae59a2844e4041db58ff36b270d1528b3bee))
+
+
+### BREAKING CHANGES
+
+* the packet containing binary data will now be sent without any transformation
+
+Protocol v3: { type: 'message', data: <Buffer 01 02 03> } => <Buffer 04 01 02 03>
+Protocol v4: { type: 'message', data: <Buffer 01 02 03> } => <Buffer 01 02 03>
+
+
+
+# [2.2.0](https://github.com/socketio/engine.io-parser/compare/2.1.3...2.2.0) (2019-09-13)
+
+
+* [refactor] Use `Buffer.allocUnsafe` instead of `new Buffer` (#104) ([aedf8eb](https://github.com/socketio/engine.io-parser/commit/aedf8eb29e8bf6aeb5c6cc68965d986c4c958ae2)), closes [#104](https://github.com/socketio/engine.io-parser/issues/104)
+
+
+### BREAKING CHANGES
+
+* drop support for Node.js 4 (since Buffer.allocUnsafe was added in v5.10.0)

+The parser can encode/decode packets, payloads, and payloads as binary
+with the following methods: `encodePacket`, `decodePacket`, `encodePayload`,
+`decodePayload`.
+
+Example:
+
+```js
+const parser = require("engine.io-parser");
+const data = Buffer.from([ 1, 2, 3, 4 ]);
+
+parser.encodePacket({ type: "message", data }, encoded => {
+  const decodedData = parser.decodePacket(encoded); // decodedData === data
+});
+```
+
+### With browserify
+
+Engine.IO Parser is a commonjs module, which means you can include it by using
+`require` on the browser and package using [browserify](http://browserify.org/):
+
+1. install the parser package
+
+    ```shell
+    npm install engine.io-parser
+    ```
+
+1. write your app code
+
+    ```js
+    const parser = require("engine.io-parser");
+
+    const testBuffer = new Int8Array(10);
+    for (let i = 0; i < testBuffer.length; i++) testBuffer[i] = i;
+
+    const packets = [{ type: "message", data: testBuffer.buffer }, { type: "message", data: "hello" }];
+
+    parser.encodePayload(packets, encoded => {
+      parser.decodePayload(encoded,
+        (packet, index, total) => {
+          const isLast = index + 1 == total;
+          if (!isLast) {
+            const buffer = new Int8Array(packet.data); // testBuffer
+          } else {
+            const message = packet.data; // "hello"
+          }
+        });
+    });
+    ```
+
+1. build your app bundle
+
+    ```bash
+    $ browserify app.js > bundle.js
+    ```
+
+1. include on your page
+
+    ```html
+    <script src="/path/to/bundle.js"></script>
+    ```
+
+## Features
+
+- Runs on browser and node.js seamlessly
+- Runs inside HTML5 WebWorker
+- Can encode and decode packets
+  - Encodes from/to ArrayBuffer or Blob when in browser, and Buffer or ArrayBuffer in Node
+
+## API
+
+Note: `cb(type)` means the type is a callback function that contains a parameter of type `type` when called.
+
+### Node
+
+- `encodePacket`
+    - Encodes a packet.
+    - **Parameters**
+      - `Object`: the packet to encode, has `type` and `data`.
+        - `data`: can be a `String`, `Number`, `Buffer`, `ArrayBuffer`
+      - `Boolean`: binary support
+      - `Function`: callback, returns the encoded packet (`cb(String)`)
+- `decodePacket`
+    - Decodes a packet. Data also available as an ArrayBuffer if requested.
+    - Returns data as `String` or (`Blob` on browser, `ArrayBuffer` on Node)
+    - **Parameters**
+      - `String` | `ArrayBuffer`: the packet to decode, has `type` and `data`
+      - `String`: optional, the binary type
+
+- `encodePayload`
+    - Encodes multiple messages (payload).
+    - If any contents are binary, they will be encoded as base64 strings. Base64
+      encoded strings are marked with a b before the length specifier
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Function`: callback, returns the encoded payload (`cb(String)`)
+- `decodePayload`
+    - Decodes data when a payload is maybe expected. Possible binary contents are
+      decoded from their base64 representation.
+    - **Parameters**
+      - `String`: the payload
+      - `Function`: callback, returns (cb(`Object`: packet, `Number`:packet index, `Number`:packet total))
+
+## Tests
+
+Standalone tests can be run with `npm test` which will run the node.js tests.
+
+Browser tests are run using [zuul](https://github.com/defunctzombie/zuul).
+(You must have zuul setup with a saucelabs account.)
+
+You can run the tests locally using the following command:
+
+```
+npm run test:browser
+```
+
+## Support
+
+The support channels for `engine.io-parser` are the same as `socket.io`:
+  - irc.freenode.net **#socket.io**
+  - [Github Discussions](https://github.com/socketio/socket.io/discussions)
+  - [Website](https://socket.io)
+

+
+
+### BREAKING CHANGES
+
+* the handlePreflightRequest option is removed by the change.
+
+Before:
+
+```
+new Server({
+  handlePreflightRequest: (req, res) => {
+    res.writeHead(200, {
+      "Access-Control-Allow-Origin": 'https://example.com',
+      "Access-Control-Allow-Methods": 'GET',
+      "Access-Control-Allow-Headers": 'Authorization',
+      "Access-Control-Allow-Credentials": true
+    });
+    res.end();
+  }
+})
+```
+
+After:
+
+```
+new Server({
+  cors: {
+    origin: "https://example.com",
+    methods: ["GET"],
+    allowedHeaders: ["Authorization"],
+    credentials: true
+  }
+})
+```
+* the syntax has changed from
+
+```
+new Server({
+  cookieName: "test",
+  cookieHttpOnly: false,
+  cookiePath: "/custom"
+})
+```
+
+to
+
+```
+new Server({
+  cookie: {
+    name: "test",
+    httpOnly: false,
+    path: "/custom"
+  }
+})
+```
+
+All other options (domain, maxAge, sameSite, ...) are now supported.
+
+* v3.x clients will not be able to connect anymore (they will send a ping packet and timeout while waiting for a pong packet).

+# Engine.IO: the realtime engine
+
+[![Build Status](https://travis-ci.org/socketio/engine.io.svg?branch=master)](http://travis-ci.org/socketio/engine.io)
+[![NPM version](https://badge.fury.io/js/engine.io.svg)](http://badge.fury.io/js/engine.io)
+
+`Engine.IO` is the implementation of transport-based
+cross-browser/cross-device bi-directional communication layer for
+[Socket.IO](http://github.com/socketio/socket.io).
+
+## How to use
+
+### Server
+
+#### (A) Listening on a port
+
+```js
+const engine = require('engine.io');
+const server = engine.listen(80);
+
+server.on('connection', socket => {
+  socket.send('utf 8 string');
+  socket.send(Buffer.from([0, 1, 2, 3, 4, 5])); // binary data
+});
+```
+
+#### (B) Intercepting requests for a http.Server
+
+```js
+const engine = require('engine.io');
+const http = require('http').createServer().listen(3000);
+const server = engine.attach(http);
+
+server.on('connection', socket => {
+  socket.on('message', data => { });
+  socket.on('close', () => { });
+});
+```
+
+#### (C) Passing in requests
+
+```js
+const engine = require('engine.io');
+const server = new engine.Server();
+
+server.on('connection', socket => {
+  socket.send('hi');
+});
+
+// …
+httpServer.on('upgrade', (req, socket, head) => {
+  server.handleUpgrade(req, socket, head);
+});
+
+httpServer.on('request', (req, res) => {
+  server.handleRequest(req, res);
+});
+```
+
+### Client
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+  const socket = new eio.Socket('ws://localhost/');
+  socket.on('open', () => {
+    socket.on('message', data => {});
+    socket.on('close', () => {});
+  });
+</script>
+```
+
+For more information on the client refer to the
+[engine-client](http://github.com/socketio/engine.io-client) repository.
+
+## What features does it have?

+  - proxies and load balancers.
+  - personal firewall and antivirus software.
+  - for more information refer to **Goals** and **Architecture** sections
+- **Minimal client size** aided by:
+  - lazy loading of flash transports.
+  - lack of redundant transports.
+- **Scalable**
+  - load balancer friendly
+- **Future proof**
+- **100% Node.JS core style**
+  - No API sugar (left for higher level projects)
+  - Written in readable vanilla JavaScript
+
+## API
+
+### Server
+
+<hr><br>
+
+#### Top-level
+
+These are exposed by `require('engine.io')`:
+
+##### Events
+
+- `flush`
+    - Called when a socket buffer is being flushed.
+    - **Arguments**
+      - `Socket`: socket being flushed
+      - `Array`: write buffer
+- `drain`
+    - Called when a socket buffer is drained
+    - **Arguments**
+      - `Socket`: socket being flushed
+
+##### Properties
+
+- `protocol` _(Number)_: protocol revision number
+- `Server`: Server class constructor
+- `Socket`: Socket class constructor
+- `Transport` _(Function)_: transport constructor
+- `transports` _(Object)_: map of available transports
+
+##### Methods
+
+- `()`
+    - Returns a new `Server` instance. If the first argument is an `http.Server` then the
+      new `Server` instance will be attached to it. Otherwise, the arguments are passed
+      directly to the `Server` constructor.
+    - **Parameters**
+      - `http.Server`: optional, server to attach to.
+      - `Object`: optional, options object (see `Server#constructor` api docs below)
+
+  The following are identical ways to instantiate a server and then attach it.
+
+```js
+const httpServer; // previously created with `http.createServer();` from node.js api.
+
+// create a server first, and then attach
+const eioServer = require('engine.io').Server();
+eioServer.attach(httpServer);
+
+// or call the module as a function to get `Server`
+const eioServer = require('engine.io')();
+eioServer.attach(httpServer);
+
+// immediately attach
+const eioServer = require('engine.io')(httpServer);
+
+// with custom options
+const eioServer = require('engine.io')(httpServer, {
+  maxHttpBufferSize: 1e3
+});
+```
+
+- `listen`
+    - Creates an `http.Server` which listens on the given port and attaches WS
+      to it. It returns `501 Not Implemented` for regular http requests.
+    - **Parameters**
+      - `Number`: port to listen on.
+      - `Object`: optional, options object
+      - `Function`: callback for `listen`.
+    - **Options**
+      - All options from `Server.attach` method, documented below.
+      - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
+    - **Returns** `Server`
+
+```js
+const engine = require('engine.io');
+const server = engine.listen(3000, {
+  pingTimeout: 2000,
+  pingInterval: 10000
+});
+
+server.on('connection', /* ... */);
+```
+
+- `attach`
+    - Captures `upgrade` requests for a `http.Server`. In other words, makes
+      a regular http.Server WebSocket-compatible.
+    - **Parameters**
+      - `http.Server`: server to attach to.
+      - `Object`: optional, options object
+    - **Options**
+      - All options from `Server.attach` method, documented below.
+      - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
+    - **Returns** `Server` a new Server instance.
+
+```js
+const engine = require('engine.io');
+const httpServer = require('http').createServer().listen(3000);
+const server = engine.attach(httpServer, {
+  wsEngine: 'uws' // requires having uws as dependency
+});
+
+server.on('connection', /* ... */);
+```

+
+## Support
+
+The support channels for `engine.io` are the same as `socket.io`:
+  - irc.freenode.net **#socket.io**
+  - [Google Groups](http://groups.google.com/group/socket_io)
+  - [Website](http://socket.io)
+
+## Development
+
+To contribute patches, run tests or benchmarks, make sure to clone the
+repository:
+
+```
+git clone git://github.com/LearnBoost/engine.io.git
+```
+
+Then:
+
+```
+cd engine.io
+npm install
+```
+
+## Tests
+
+Tests run with `npm test`. It runs the server tests that are aided by
+the usage of `engine.io-client`.
+
+Make sure `npm install` is run first.
+
+## Goals
+
+The main goal of `Engine` is ensuring the most reliable realtime communication.
+Unlike the previous Socket.IO core, it always establishes a long-polling
+connection first, then tries to upgrade to better transports that are "tested" on
+the side.
+
+During the lifetime of the Socket.IO projects, we've found countless drawbacks
+to relying on `HTML5 WebSocket` or `Flash Socket` as the first connection
+mechanisms.
+
+Both are clearly the _right way_ of establishing a bidirectional communication,
+with HTML5 WebSocket being the way of the future. However, to answer most business
+needs, alternative traditional HTTP 1.1 mechanisms are just as good as delivering
+the same solution.
+
+WebSocket based connections have two fundamental benefits:
+
+1. **Better server performance**
+  - _A: Load balancers_<br>
+      Load balancing a long polling connection poses a serious architectural nightmare
+      since requests can come from any number of open sockets by the user agent, but
+      they all need to be routed to the process and computer that owns the `Engine`
+      connection. This negatively impacts RAM and CPU usage.
+  - _B: Network traffic_<br>
+      WebSocket is designed around the premise that each message frame has to be
+      surrounded by the least amount of data. In HTTP 1.1 transports, each message
+      frame is surrounded by HTTP headers and chunked encoding frames. If you try to
+      send the message _"Hello world"_ with xhr-polling, the message ultimately
+      becomes larger than if you were to send it with WebSocket.
+  - _C: Lightweight parser_<br>
+      As an effect of **B**, the server has to do a lot more work to parse the network
+      data and figure out the message when traditional HTTP requests are used
+      (as in long polling). This means that another advantage of WebSocket is
+      less server CPU usage.
+
+2. **Better user experience**
+
+    Due to the reasons stated in point **1**, the most important effect of being able
+    to establish a WebSocket connection is raw data transfer speed, which translates
+    in _some_ cases in better user experience.
+
+    Applications with heavy realtime interaction (such as games) will benefit greatly,
+    whereas applications like realtime chat (Gmail/Facebook), newsfeeds (Facebook) or
+    timelines (Twitter) will have negligible user experience improvements.
+
+Having said this, attempting to establish a WebSocket connection directly so far has
+proven problematic:
+
+1. **Proxies**<br>
+    Many corporate proxies block WebSocket traffic.
+
+2. **Personal firewall and antivirus software**<br>
+    As a result of our research, we've found that at least 3 personal security
+    applications block WebSocket traffic.
+
+3. **Cloud application platforms**<br>
+    Platforms like Heroku or No.de have had trouble keeping up with the fast-paced
+    nature of the evolution of the WebSocket protocol. Applications therefore end up
+    inevitably using long polling, but the seamless installation experience of
+    Socket.IO we strive for (_"require() it and it just works"_) disappears.
+
+Some of these problems have solutions. In the case of proxies and personal programs,
+however, the solutions many times involve upgrading software. Experience has shown
+that relying on client software upgrades to deliver a business solution is
+fruitless: the very existence of this project has to do with a fragmented panorama
+of user agent distribution, with clients connecting with latest versions of the most
+modern user agents (Chrome, Firefox and Safari), but others with versions as low as
+IE 5.5.
+
+From the user perspective, an unsuccessful WebSocket connection can translate in
+up to at least 10 seconds of waiting for the realtime application to begin
+exchanging data. This **perceptively** hurts user experience.
+
+To summarize, **Engine** focuses on reliability and user experience first, marginal
+potential UX improvements and increased server performance second. `Engine` is the
+result of all the lessons learned with WebSocket in the wild.
+
+## Architecture
+
+The main premise of `Engine`, and the core of its existence, is the ability to
+swap transports on the fly. A connection starts as xhr-polling, but it can
+switch to WebSocket.
+
+The central problem this poses is: how do we switch transports without losing
+messages?
+
+`Engine` only switches from polling to another transport in between polling
+cycles. Since the server closes the connection after a certain timeout when
+there's no activity, and the polling transport implementation buffers messages
+in between connections, this ensures no message loss and optimal performance.
+
+Another benefit of this design is that we workaround almost all the limitations
+of **Flash Socket**, such as slow connection times, increased file size (we can
+safely lazy load it without hurting user experience), etc.
+
+## FAQ
+
+### Can I use engine without Socket.IO ?
+
+Absolutely. Although the recommended framework for building realtime applications
+is Socket.IO, since it provides fundamental features for real-world applications
+such as multiplexing, reconnection support, etc.
+
+`Engine` is to Socket.IO what Connect is to Express. An essential piece for building
+realtime frameworks, but something you _probably_ won't be using for building
+actual applications.
+
+### Does the server serve the client?
+
+No. The main reason is that `Engine` is meant to be bundled with frameworks.
+Socket.IO includes `Engine`, therefore serving two clients is not necessary. If
+you use Socket.IO, including
+
+```html
+<script src="/socket.io/socket.io.js">
+```
+
+has you covered.
+
+### Can I implement `Engine` in other languages?
+
+Absolutely. The [engine.io-protocol](https://github.com/socketio/engine.io-protocol)
+repository contains the most up-to-date description of the specification
+at all times.

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

+
+This is a database of all mime types.
+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
+
+<!-- eslint-disable no-unused-vars -->
+
+```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.json` or
+`src/custom-suffix.json`.
+
+The `src/custom.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
+
+<!-- eslint-disable no-unused-vars -->
+
+```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.
+
+<!-- eslint-disable no-undef -->
+
+```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.
+
+<!-- eslint-disable no-undef -->
+
+```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.
+
+<!-- eslint-disable no-undef -->
+
+```js
+mime.extension('application/octet-stream') // 'bin'
+```
+
+### mime.charset(type)
+
+Lookup the implied default charset of a content-type.
+
+<!-- eslint-disable no-undef -->
+
+```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.

+# ms
+
+[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
+[![Join the community on Spectrum](https://withspectrum.github.io/badge/badge.svg)](https://spectrum.chat/zeit)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h')      // 7200000
+ms('1m')      // 60000
+ms('5s')      // 5000
+ms('1y')      // 31557600000
+ms('100')     // 100
+ms('-3 days') // -259200000
+ms('-1h')     // -3600000
+ms('-200')    // -200
+```
+
+### Convert from Milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(-3 * 60000)        // "-3m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time Format Written-Out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(-3 * 60000, { long: true })        // "-3 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [Node.js](https://nodejs.org) and in the browser
+- If a number is supplied to `ms`, a string with a unit is returned
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
+- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
+
+## Related Packages
+
+- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
+
+## Caught a Bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+
+An HTTP content negotiator for Node.js
+
+## Installation
+
+```sh
+$ npm install negotiator
+```
+
+## API
+
+```js
+var Negotiator = require('negotiator')
+```
+
+### Accept Negotiation
+
+```js
+availableMediaTypes = ['text/html', 'text/plain', 'application/json']
+
+// The negotiator constructor receives a request object
+negotiator = new Negotiator(request)
+
+// Let's say Accept header is 'text/html, application/*;q=0.2, image/jpeg;q=0.8'
+
+negotiator.mediaTypes()
+// -> ['text/html', 'image/jpeg', 'application/*']
+
+negotiator.mediaTypes(availableMediaTypes)
+// -> ['text/html', 'application/json']
+
+negotiator.mediaType(availableMediaTypes)
+// -> 'text/html'
+```
+
+You can check a working example at `examples/accept.js`.
+
+#### Methods
+
+##### mediaType()
+
+Returns the most preferred media type from the client.
+
+##### mediaType(availableMediaType)
+
+Returns the most preferred media type from a list of available media types.
+
+##### mediaTypes()
+
+Returns an array of preferred media types ordered by the client preference.
+
+##### mediaTypes(availableMediaTypes)
+
+Returns an array of preferred media types ordered by priority from a list of
+available media types.
+
+### Accept-Language Negotiation
+
+```js
+negotiator = new Negotiator(request)
+
+availableLanguages = ['en', 'es', 'fr']
+
+// Let's say Accept-Language header is 'en;q=0.8, es, pt'
+
+negotiator.languages()
+// -> ['es', 'pt', 'en']
+
+negotiator.languages(availableLanguages)
+// -> ['es', 'en']
+
+language = negotiator.language(availableLanguages)
+// -> 'es'
+```
+
+You can check a working example at `examples/language.js`.
+
+#### Methods
+
+##### language()
+
+Returns the most preferred language from the client.
+
+##### language(availableLanguages)
+
+Returns the most preferred language from a list of available languages.
+
+##### languages()
+
+Returns an array of preferred languages ordered by the client preference.
+
+##### languages(availableLanguages)
+
+Returns an array of preferred languages ordered by priority from a list of
+available languages.
+
+### Accept-Charset Negotiation
+
+```js
+availableCharsets = ['utf-8', 'iso-8859-1', 'iso-8859-5']
+
+negotiator = new Negotiator(request)
+
+// Let's say Accept-Charset header is 'utf-8, iso-8859-1;q=0.8, utf-7;q=0.2'
+
+negotiator.charsets()
+// -> ['utf-8', 'iso-8859-1', 'utf-7']
+
+negotiator.charsets(availableCharsets)
+// -> ['utf-8', 'iso-8859-1']
+
+negotiator.charset(availableCharsets)
+// -> 'utf-8'
+```
+
+You can check a working example at `examples/charset.js`.
+
+#### Methods
+
+##### charset()
+
+Returns the most preferred charset from the client.
+
+##### charset(availableCharsets)
+
+Returns the most preferred charset from a list of available charsets.
+
+##### charsets()
+
+Returns an array of preferred charsets ordered by the client preference.
+
+##### charsets(availableCharsets)
+
+Returns an array of preferred charsets ordered by priority from a list of
+available charsets.
+
+### Accept-Encoding Negotiation
+
+```js
+availableEncodings = ['identity', 'gzip']
+
+negotiator = new Negotiator(request)
+
+// Let's say Accept-Encoding header is 'gzip, compress;q=0.2, identity;q=0.5'
+
+negotiator.encodings()
+// -> ['gzip', 'identity', 'compress']
+
+negotiator.encodings(availableEncodings)
+// -> ['gzip', 'identity']
+
+negotiator.encoding(availableEncodings)
+// -> 'gzip'
+```
+
+You can check a working example at `examples/encoding.js`.
+
+#### Methods
+
+##### encoding()
+
+Returns the most preferred encoding from the client.
+
+##### encoding(availableEncodings)
+
+Returns the most preferred encoding from a list of available encodings.
+
+##### encodings()
+
+Returns an array of preferred encodings ordered by the client preference.
+
+##### encodings(availableEncodings)
+
+Returns an array of preferred encodings ordered by priority from a list of
+available encodings.

+# object-assign [![Build Status](https://travis-ci.org/sindresorhus/object-assign.svg?branch=master)](https://travis-ci.org/sindresorhus/object-assign)
+
+> ES2015 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) [ponyfill](https://ponyfill.com)
+
+
+## Use the built-in
+
+Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),
+support `Object.assign()` :tada:. If you target only those environments, then by all
+means, use `Object.assign()` instead of this package.
+
+
+## Install
+
+```
+$ npm install --save object-assign
+```
+
+
+## Usage
+
+```js
+const objectAssign = require('object-assign');
+
+objectAssign({foo: 0}, {bar: 1});
+//=> {foo: 0, bar: 1}
+
+// multiple sources
+objectAssign({foo: 0}, {bar: 1}, {baz: 2});
+//=> {foo: 0, bar: 1, baz: 2}
+
+// overwrites equal keys
+objectAssign({foo: 0}, {foo: 1}, {foo: 2});
+//=> {foo: 2}
+
+// ignores null and undefined sources
+objectAssign({foo: 0}, null, {bar: 1}, undefined);
+//=> {foo: 0, bar: 1}
+```
+
+
+## API
+
+### objectAssign(target, [source, ...])
+
+Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

+# socket.io-adapter
+
+Default socket.io in-memory adapter class.
+
+Compatibility table:
+
+| Adapter version | Socket.IO server version |
+|-----------------| ------------------------ |
+| 1.x.x           | 1.x.x / 2.x.x            |
+| 2.x.x           | 3.x.x                    |
+
+## How to use
+
+This module is not intended for end-user usage, but can be used as an
+interface to inherit from other adapters you might want to build.
+
+As an example of an adapter that builds on top of this, please take a look
+at [socket.io-redis](https://github.com/learnboost/socket.io-redis).

+## [4.0.1](https://github.com/socketio/socket.io-parser/compare/3.4.1...4.0.1) (2020-11-05)
+
+### Features
+
+* move binary detection back to the parser ([285e7cd](https://github.com/socketio/socket.io-parser/commit/285e7cd0d837adfc911c999e7294788681226ae1))
+* add support for a payload in a CONNECT packet ([78f9fc2](https://github.com/socketio/socket.io-parser/commit/78f9fc2999b15804b02f2c22a2b4007734a26af9))
+
+### Bug Fixes
+
+* do not catch encoding errors ([aeae87c](https://github.com/socketio/socket.io-parser/commit/aeae87c220287197cb78370dbd86b950a7dd29eb))
+* throw upon invalid payload format ([c327acb](https://github.com/socketio/socket.io-parser/commit/c327acbc3c3c2d0b2b439136cbcb56c81db173d6))
+
+### BREAKING CHANGES
+
+* the encode method is now synchronous ([28d4f03](https://github.com/socketio/socket.io-parser/commit/28d4f0309bdd9e306b78d1946d3e1760941d6544))
+
+
+
+## [4.0.1-rc3](https://github.com/socketio/socket.io-parser/compare/4.0.1-rc2...4.0.1-rc3) (2020-10-25)
+
+
+
+## [4.0.1-rc2](https://github.com/socketio/socket.io-parser/compare/4.0.1-rc1...4.0.1-rc2) (2020-10-15)
+
+
+### Features
+
+* move binary detection back to the parser ([285e7cd](https://github.com/socketio/socket.io-parser/commit/285e7cd0d837adfc911c999e7294788681226ae1))
+
+
+
+## [4.0.1-rc1](https://github.com/socketio/socket.io-parser/compare/4.0.0...4.0.1-rc1) (2020-10-12)
+
+
+### Features
+
+* add support for a payload in a CONNECT packet ([78f9fc2](https://github.com/socketio/socket.io-parser/commit/78f9fc2999b15804b02f2c22a2b4007734a26af9))
+
+
+
+## [3.3.1](https://github.com/socketio/socket.io-parser/compare/3.3.0...3.3.1) (2020-09-30)
+
+
+# [4.0.0](https://github.com/socketio/socket.io-parser/compare/3.4.1...4.0.0) (2020-09-28)
+
+This release will be included in Socket.IO v3.
+
+There is a breaking API change (see below), but the exchange [protocol](https://github.com/socketio/socket.io-protocol) is left untouched and thus stays in version 4.
+
+### Bug Fixes
+
+* do not catch encoding errors ([aeae87c](https://github.com/socketio/socket.io-parser/commit/aeae87c220287197cb78370dbd86b950a7dd29eb))
+* throw upon invalid payload format ([c327acb](https://github.com/socketio/socket.io-parser/commit/c327acbc3c3c2d0b2b439136cbcb56c81db173d6))

+
+[![Build Status](https://secure.travis-ci.org/socketio/socket.io-parser.svg?branch=master)](http://travis-ci.org/socketio/socket.io-parser)
+[![NPM version](https://badge.fury.io/js/socket.io-parser.svg)](http://badge.fury.io/js/socket.io-parser)
+
+A socket.io encoder and decoder written in JavaScript complying with version `4`
+of [socket.io-protocol](https://github.com/socketio/socket.io-protocol).
+Used by [socket.io](https://github.com/automattic/socket.io) and
+[socket.io-client](https://github.com/automattic/socket.io-client).
+
+## Parser API
+
+  socket.io-parser is the reference implementation of socket.io-protocol. Read
+  the full API here:
+  [socket.io-protocol](https://github.com/learnboost/socket.io-protocol).
+
+## Example Usage
+
+### Encoding and decoding a packet
+
+```js
+var parser = require('socket.io-parser');
+var encoder = new parser.Encoder();
+var packet = {
+  type: parser.EVENT,
+  data: 'test-packet',
+  id: 13
+};
+encoder.encode(packet, function(encodedPackets) {
+  var decoder = new parser.Decoder();
+  decoder.on('decoded', function(decodedPacket) {
+    // decodedPacket.type == parser.EVENT
+    // decodedPacket.data == 'test-packet'
+    // decodedPacket.id == 13
+  });
+
+  for (var i = 0; i < encodedPackets.length; i++) {
+    decoder.add(encodedPackets[i]);
+  }
+});
+```
+
+### Encoding and decoding a packet with binary data
+
+```js
+var parser = require('socket.io-parser');
+var encoder = new parser.Encoder();
+var packet = {
+  type: parser.BINARY_EVENT,
+  data: {i: new Buffer(1234), j: new Blob([new ArrayBuffer(2)])},
+  id: 15
+};
+encoder.encode(packet, function(encodedPackets) {
+  var decoder = new parser.Decoder();
+  decoder.on('decoded', function(decodedPacket) {
+    // decodedPacket.type == parser.BINARY_EVENT
+    // Buffer.isBuffer(decodedPacket.data.i) == true
+    // Buffer.isBuffer(decodedPacket.data.j) == true
+    // decodedPacket.id == 15
+  });
+
+  for (var i = 0; i < encodedPackets.length; i++) {
+    decoder.add(encodedPackets[i]);
+  }
+});
+```
+See the test suite for more examples of how socket.io-parser is used.

+* do not reuse the Engine.IO id ([2875d2c](https://github.com/socketio/socket.io/commit/2875d2cfdfa463e64cb520099749f543bbc4eb15))

+
+### BREAKING CHANGES
+
+* the Socket#use() method is removed (see [5c73733](https://github.com/socketio/socket.io/commit/5c737339858d59eab4b5ee2dd6feff0e82c4fe5a))
+
+* Socket#join() and Socket#leave() do not accept a callback argument anymore.
+
+Before:
+
+```js
+socket.join("room1", () => {
+ io.to("room1").emit("hello");
+});
+```
+
+After:
+
+```js
+socket.join("room1");
+io.to("room1").emit("hello");
+// or await socket.join("room1"); for custom adapters
+```
+
+* the "connected" map is renamed to "sockets"
+* the Socket#binary() method is removed, as this use case is now covered by the ability to provide your own parser.
+* the 'origins' option is removed
+
+Before:
+
+```js
+new Server(3000, {
+  origins: ["https://example.com"]
+});
+```
+
+The 'origins' option was used in the allowRequest method, in order to
+determine whether the request should pass or not. And the Engine.IO
+server would implicitly add the necessary Access-Control-Allow-xxx
+headers.
+
+After:
+
+```js
+new Server(3000, {
+  cors: {
+    origin: "https://example.com",
+    methods: ["GET", "POST"],
+    allowedHeaders: ["content-type"]
+  }
+});
+```
+
+The already existing 'allowRequest' option can be used for validation:
+
+```js
+new Server(3000, {
+  allowRequest: (req, callback) => {
+    callback(null, req.headers.referer.startsWith("https://example.com"));
+  }
+});
+```
+
+* Socket#rooms is now a Set instead of an object
+
+* Namespace#connected is now a Map instead of an object
+
+* there is no more implicit connection to the default namespace:
+
+```js
+// client-side
+const socket = io("/admin");
+
+// server-side
+io.on("connect", socket => {
+  // not triggered anymore
+})
+
+io.use((socket, next) => {
+  // not triggered anymore
+});
+
+io.of("/admin").use((socket, next) => {
+  // triggered
+});
+```
+
+* the Server#set() method was removed
+
+This method was kept for backward-compatibility with pre-1.0 versions.

+
+## Features
+
+Socket.IO enables real-time bidirectional event-based communication. It consists of:
+
+- a Node.js server (this repository)
+- a [Javascript client library](https://github.com/socketio/socket.io-client) for the browser (or a Node.js client)
+
+Some implementations in other languages are also available:
+
+- [Java](https://github.com/socketio/socket.io-client-java)
+- [C++](https://github.com/socketio/socket.io-client-cpp)
+- [Swift](https://github.com/socketio/socket.io-client-swift)
+- [Dart](https://github.com/rikulo/socket.io-client-dart)
+
+Its main features are:
+
+#### Reliability
+
+Connections are established even in the presence of:
+  - proxies and load balancers.
+  - personal firewall and antivirus software.
+
+For this purpose, it relies on [Engine.IO](https://github.com/socketio/engine.io), which first establishes a long-polling connection, then tries to upgrade to better transports that are "tested" on the side, like WebSocket. Please see the [Goals](https://github.com/socketio/engine.io#goals) section for more information.
+
+#### Auto-reconnection support
+
+Unless instructed otherwise a disconnected client will try to reconnect forever, until the server is available again. Please see the available reconnection options [here](https://github.com/socketio/socket.io-client/blob/master/docs/API.md#new-managerurl-options).
+
+#### Disconnection detection
+
+A heartbeat mechanism is implemented at the Engine.IO level, allowing both the server and the client to know when the other one is not responding anymore.
+
+That functionality is achieved with timers set on both the server and the client, with timeout values (the `pingInterval` and `pingTimeout` parameters) shared during the connection handshake. Those timers require any subsequent client calls to be directed to the same server, hence the `sticky-session` requirement when using multiples nodes.
+
+#### Binary support
+
+Any serializable data structures can be emitted, including:
+
+- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) in the browser
+- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Buffer](https://nodejs.org/api/buffer.html) in Node.js
+
+#### Simple and convenient API
+
+Sample code:
+
+```js
+io.on('connection', socket => {
+  socket.emit('request', /* … */); // emit an event to the socket
+  io.emit('broadcast', /* … */); // emit an event to all connected sockets
+  socket.on('reply', () => { /* … */ }); // listen to the event
+});
+```
+
+#### Cross-browser
+
+Browser support is tested in Sauce Labs:
+
+[![Sauce Test Status](https://saucelabs.com/browser-matrix/socket.svg)](https://saucelabs.com/u/socket)
+
+#### Multiplexing support
+
+In order to create separation of concerns within your application (for example per module, or based on permissions), Socket.IO allows you to create several `Namespaces`, which will act as separate communication channels but will share the same underlying connection.
+
+#### Room support
+
+Within each `Namespace`, you can define arbitrary channels, called `Rooms`, that sockets can join and leave. You can then broadcast to any given room, reaching every socket that has joined it.
+
+This is a useful feature to send notifications to a group of users, or to a given user connected on several devices for example.
+
+
+**Note:** Socket.IO is not a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds some metadata to each packet: the packet type, the namespace and the ack id when a message acknowledgement is needed. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a WebSocket server (like `ws://echo.websocket.org`) either. Please see the protocol specification [here](https://github.com/socketio/socket.io-protocol).
+
+## Installation
+
+```bash
+npm install socket.io
+```
+
+## How to use
+
+The following example attaches socket.io to a plain Node.JS
+HTTP server listening on port `3000`.
+
+```js
+const server = require('http').createServer();
+const io = require('socket.io')(server);
+io.on('connection', client => {
+  client.on('event', data => { /* … */ });
+  client.on('disconnect', () => { /* … */ });
+});
+server.listen(3000);
+```
+
+### Standalone
+
+```js
+const io = require('socket.io')();
+io.on('connection', client => { ... });
+io.listen(3000);
+```
+
+### In conjunction with Express
+
+Starting with **3.0**, express applications have become request handler
+functions that you pass to `http` or `http` `Server` instances. You need
+to pass the `Server` to `socket.io`, and not the express application
+function. Also make sure to call `.listen` on the `server`, not the `app`.
+
+```js
+const app = require('express')();
+const server = require('http').createServer(app);
+const io = require('socket.io')(server);
+io.on('connection', () => { /* … */ });
+server.listen(3000);
+```
+
+### In conjunction with Koa
+
+Like Express.JS, Koa works by exposing an application as a request
+handler function, but only by calling the `callback` method.
+
+```js
+const app = require('koa')();
+const server = require('http').createServer(app.callback());
+const io = require('socket.io')(server);
+io.on('connection', () => { /* … */ });
+server.listen(3000);
+```
+
+### In conjunction with Fastify
+
+To integrate Socket.io in your Fastify application you just need to
+register `fastify-socket.io` plugin. It will create a `decorator`
+called `io`.
+
+```js
+const app = require('fastify')();
+app.register(require('fastify-socket.io'));
+app.io.on('connection', () => { /* … */ });
+app.listen(3000);
+```
+
+## Documentation
+
+Please see the documentation [here](https://socket.io/docs/).
+
+The source code of the website can be found [here](https://github.com/socketio/socket.io-website). Contributions are welcome!
+
+## Debug / logging
+
+Socket.IO is powered by [debug](https://github.com/visionmedia/debug).
+In order to see all the debug output, run your app with the environment variable
+`DEBUG` including the desired scope.
+
+To see the output from all of Socket.IO's debugging scopes you can use:
+
+```
+DEBUG=socket.io* node myapp
+```
+
+## Testing
+
+```
+npm test
+```
+This runs the `gulp` task `test`. By default the test will be run with the source code in `lib` directory.
+
+Set the environmental variable `TEST_VERSION` to `compat` to test the transpiled es5-compat version of the code.
+
+The `gulp` task `test` will always transpile the source code into es5 and export to `dist` first before running the test.

+
+Manipulate the HTTP Vary header
+
+## Installation
+
+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 vary
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var vary = require('vary')
+```
+
+### vary(res, field)
+
+Adds the given header `field` to the `Vary` response header of `res`.
+This can be a string of a single field, a string of a valid `Vary`
+header, or an array of multiple fields.
+
+This will append the header if not already listed, otherwise leaves
+it listed in the current location.
+
+<!-- eslint-disable no-undef -->
+
+```js
+// Append "Origin" to the Vary header of the response
+vary(res, 'Origin')
+```
+
+### vary.append(header, field)
+
+Adds the given header `field` to the `Vary` response header string `header`.
+This can be a string of a single field, a string of a valid `Vary` header,
+or an array of multiple fields.
+
+This will append the header if not already listed, otherwise leaves
+it listed in the current location. The new header string is returned.
+
+<!-- eslint-disable no-undef -->
+
+```js
+// Get header string appending "Origin" to "Accept, User-Agent"
+vary.append('Accept, User-Agent', 'Origin')
+```
+
+## Examples
+
+### Updating the Vary header when content is based on it
+
+```js
+var http = require('http')
+var vary = require('vary')
+
+http.createServer(function onRequest (req, res) {
+  // about to user-agent sniff
+  vary(res, 'User-Agent')
+
+  var ua = req.headers['user-agent'] || ''
+  var isMobile = /mobi|android|touch|mini/i.test(ua)
+
+  // serve site, depending on isMobile
+  res.setHeader('Content-Type', 'text/html')
+  res.end('You are (probably) ' + (isMobile ? '' : 'not ') + 'a mobile user')
+})
+```
+
+## Testing
+
+```sh
+$ npm test
+```

+# ws: a Node.js WebSocket library
+
+[![Version npm](https://img.shields.io/npm/v/ws.svg?logo=npm)](https://www.npmjs.com/package/ws)
+[![Build](https://img.shields.io/travis/websockets/ws/master.svg?logo=travis)](https://travis-ci.com/websockets/ws)
+[![Windows x86 Build](https://img.shields.io/appveyor/ci/lpinca/ws/master.svg?logo=appveyor)](https://ci.appveyor.com/project/lpinca/ws)
+[![Coverage Status](https://img.shields.io/coveralls/websockets/ws/master.svg)](https://coveralls.io/github/websockets/ws)
+
+ws is a simple to use, blazing fast, and thoroughly tested WebSocket client and
+server implementation.
+
+Passes the quite extensive Autobahn test suite: [server][server-report],
+[client][client-report].
+
+**Note**: This module does not work in the browser. The client in the docs is a
+reference to a back end with the role of a client in the WebSocket
+communication. Browser clients must use the native
+[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket)
+object. To make the same code work seamlessly on Node.js and the browser, you
+can use one of the many wrappers available on npm, like
+[isomorphic-ws](https://github.com/heineiuo/isomorphic-ws).

+## Protocol support
+
+- **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
+- **HyBi drafts 13-17** (Current default, alternatively option
+  `protocolVersion: 13`)
+
+## Installing
+
+```
+npm install ws
+```
+
+### Opt-in for performance and spec compliance
+
+There are 2 optional modules that can be installed along side with the ws
+module. These modules are binary addons which improve certain operations.
+Prebuilt binaries are available for the most popular platforms so you don't
+necessarily need to have a C++ compiler installed on your machine.
+
+- `npm install --save-optional bufferutil`: Allows to efficiently perform
+  operations such as masking and unmasking the data payload of the WebSocket
+  frames.
+- `npm install --save-optional utf-8-validate`: Allows to efficiently check if a
+  message contains valid UTF-8 as required by the spec.
+
+## API docs
+
+See [`/doc/ws.md`](./doc/ws.md) for Node.js-like documentation of ws classes and
+utility functions.
+
+## WebSocket compression
+
+ws supports the [permessage-deflate extension][permessage-deflate] which enables
+the client and server to negotiate a compression algorithm and its parameters,
+and then selectively apply it to the data payloads of each WebSocket message.
+
+The extension is disabled by default on the server and enabled by default on the
+client. It adds a significant overhead in terms of performance and memory
+consumption so we suggest to enable it only if it is really needed.
+
+Note that Node.js has a variety of issues with high-performance compression,
+where increased concurrency, especially on Linux, can lead to [catastrophic
+memory fragmentation][node-zlib-bug] and slow performance. If you intend to use
+permessage-deflate in production, it is worthwhile to set up a test
+representative of your workload and ensure Node.js/zlib will handle it with
+acceptable performance and memory usage.
+
+Tuning of permessage-deflate can be done via the options defined below. You can
+also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly
+into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs].
+
+See [the docs][ws-server-options] for more options.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({
+  port: 8080,
+  perMessageDeflate: {
+    zlibDeflateOptions: {
+      // See zlib defaults.
+      chunkSize: 1024,
+      memLevel: 7,
+      level: 3
+    },
+    zlibInflateOptions: {
+      chunkSize: 10 * 1024
+    },
+    // Other options settable:
+    clientNoContextTakeover: true, // Defaults to negotiated value.
+    serverNoContextTakeover: true, // Defaults to negotiated value.
+    serverMaxWindowBits: 10, // Defaults to negotiated value.
+    // Below options specified as default values.
+    concurrencyLimit: 10, // Limits zlib concurrency for perf.
+    threshold: 1024 // Size (in bytes) below which messages
+    // should not be compressed.
+  }
+});
+```
+
+The client will only use the extension if it is supported and enabled on the
+server. To always disable the extension on the client set the
+`perMessageDeflate` option to `false`.
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path', {
+  perMessageDeflate: false
+});
+```
+
+## Usage examples
+
+### Sending and receiving text data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  ws.send('something');
+});
+
+ws.on('message', function incoming(data) {
+  console.log(data);
+});
+```
+
+### Sending binary data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  const array = new Float32Array(5);
+
+  for (var i = 0; i < array.length; ++i) {
+    array[i] = i / 2;
+  }
+
+  ws.send(array);
+});
+```
+
+### Simple server
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+```
+
+### External HTTP/S server
+
+```js
+const fs = require('fs');
+const https = require('https');
+const WebSocket = require('ws');
+
+const server = https.createServer({
+  cert: fs.readFileSync('/path/to/cert.pem'),
+  key: fs.readFileSync('/path/to/key.pem')
+});
+const wss = new WebSocket.Server({ server });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+
+server.listen(8080);
+```
+
+### Multiple servers sharing a single HTTP/S server
+
+```js
+const http = require('http');
+const WebSocket = require('ws');
+const url = require('url');
+
+const server = http.createServer();
+const wss1 = new WebSocket.Server({ noServer: true });
+const wss2 = new WebSocket.Server({ noServer: true });
+
+wss1.on('connection', function connection(ws) {
+  // ...
+});
+
+wss2.on('connection', function connection(ws) {
+  // ...
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+  const pathname = url.parse(request.url).pathname;
+
+  if (pathname === '/foo') {
+    wss1.handleUpgrade(request, socket, head, function done(ws) {
+      wss1.emit('connection', ws, request);
+    });
+  } else if (pathname === '/bar') {
+    wss2.handleUpgrade(request, socket, head, function done(ws) {
+      wss2.emit('connection', ws, request);
+    });
+  } else {
+    socket.destroy();
+  }
+});
+
+server.listen(8080);
+```
+
+### Client authentication
+
+```js
+const http = require('http');
+const WebSocket = require('ws');
+
+const server = http.createServer();
+const wss = new WebSocket.Server({ noServer: true });
+
+wss.on('connection', function connection(ws, request, client) {
+  ws.on('message', function message(msg) {
+    console.log(`Received message ${msg} from user ${client}`);
+  });
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+  // This function is not defined on purpose. Implement it with your own logic.
+  authenticate(request, (err, client) => {
+    if (err || !client) {
+      socket.write('HTTP/1.1 401 Unauthorized\r\n\r\n');
+      socket.destroy();
+      return;
+    }
+
+    wss.handleUpgrade(request, socket, head, function done(ws) {
+      wss.emit('connection', ws, request, client);
+    });
+  });
+});
+
+server.listen(8080);
+```
+
+Also see the provided [example][session-parse-example] using `express-session`.
+
+### Server broadcast
+
+A client WebSocket broadcasting to all connected WebSocket clients, including
+itself.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(data) {
+    wss.clients.forEach(function each(client) {
+      if (client.readyState === WebSocket.OPEN) {
+        client.send(data);
+      }
+    });
+  });
+});
+```
+
+A client WebSocket broadcasting to every other connected WebSocket clients,
+excluding itself.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(data) {
+    wss.clients.forEach(function each(client) {
+      if (client !== ws && client.readyState === WebSocket.OPEN) {
+        client.send(data);
+      }
+    });
+  });
+});
+```
+
+### echo.websocket.org demo
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+  origin: 'https://websocket.org'
+});
+
+ws.on('open', function open() {
+  console.log('connected');
+  ws.send(Date.now());
+});
+
+ws.on('close', function close() {
+  console.log('disconnected');
+});
+
+ws.on('message', function incoming(data) {
+  console.log(`Roundtrip time: ${Date.now() - data} ms`);
+
+  setTimeout(function timeout() {
+    ws.send(Date.now());
+  }, 500);
+});
+```
+
+### Use the Node.js streams API
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+  origin: 'https://websocket.org'
+});
+
+const duplex = WebSocket.createWebSocketStream(ws, { encoding: 'utf8' });
+
+duplex.pipe(process.stdout);
+process.stdin.pipe(duplex);
+```
+
+### Other examples
+
+For a full example with a browser client communicating with a ws server, see the
+examples folder.
+
+Otherwise, see the test cases.
+
+## FAQ
+
+### How to get the IP address of the client?
+
+The remote IP address can be obtained from the raw socket.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws, req) {
+  const ip = req.socket.remoteAddress;
+});
+```
+
+When the server runs behind a proxy like NGINX, the de-facto standard is to use
+the `X-Forwarded-For` header.
+
+```js
+wss.on('connection', function connection(ws, req) {
+  const ip = req.headers['x-forwarded-for'].split(/\s*,\s*/)[0];
+});
+```
+
+### How to detect and close broken connections?
+
+Sometimes the link between the server and the client can be interrupted in a way
+that keeps both the server and the client unaware of the broken state of the
+connection (e.g. when pulling the cord).
+
+In these cases ping messages can be used as a means to verify that the remote
+endpoint is still responsive.
+
+```js
+const WebSocket = require('ws');
+
+function noop() {}
+
+function heartbeat() {
+  this.isAlive = true;
+}
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.isAlive = true;
+  ws.on('pong', heartbeat);
+});
+
+const interval = setInterval(function ping() {
+  wss.clients.forEach(function each(ws) {
+    if (ws.isAlive === false) return ws.terminate();
+
+    ws.isAlive = false;
+    ws.ping(noop);
+  });
+}, 30000);
+
+wss.on('close', function close() {
+  clearInterval(interval);
+});
+```
+
+Pong messages are automatically sent in response to ping messages as required by
+the spec.
+
+Just like the server example above your clients might as well lose connection
+without knowing it. You might want to add a ping listener on your clients to
+prevent that. A simple implementation would be:
+
+```js
+const WebSocket = require('ws');
+
+function heartbeat() {
+  clearTimeout(this.pingTimeout);
+
+  // Use `WebSocket#terminate()`, which immediately destroys the connection,
+  // instead of `WebSocket#close()`, which waits for the close timer.
+  // Delay should be equal to the interval at which your server
+  // sends out pings plus a conservative assumption of the latency.
+  this.pingTimeout = setTimeout(() => {
+    this.terminate();
+  }, 30000 + 1000);
+}
+
+const client = new WebSocket('wss://echo.websocket.org/');
+
+client.on('open', heartbeat);
+client.on('ping', heartbeat);
+client.on('close', function clear() {
+  clearTimeout(this.pingTimeout);
+});
+```
+
+### How to connect via a proxy?
+
+Use a custom `http.Agent` implementation like [https-proxy-agent][] or
+[socks-proxy-agent][].
