+
+![npm package](https://img.shields.io/npm/v/@react-native/dev-middleware?color=brightgreen&label=npm%20package)
+
+Dev server middleware supporting core React Native development features. This package is preconfigured in all React Native projects.
+
+## Usage
+
+Middleware can be attached to a dev server (e.g. [Metro](https://facebook.github.io/metro/docs/getting-started)) using the `createDevMiddleware` API.
+
+```js
+import { createDevMiddleware } from '@react-native/dev-middleware';
+
+function myDevServerImpl(args) {
+  ...
+
+  const {middleware, websocketEndpoints} = createDevMiddleware({
+    projectRoot: metroConfig.projectRoot,
+    serverBaseUrl: `http://${args.host}:${args.port}`,
+    logger,
+  });
+
+  await Metro.runServer(metroConfig, {
+    host: args.host,
+    ...,
+    unstable_extraMiddleware: [
+      middleware,
+      // Optionally extend with additional HTTP middleware
+    ],
+    websocketEndpoints: {
+      ...websocketEndpoints,
+      // Optionally extend with additional WebSocket endpoints
+    },
+  });
+}
+```
+
+## Included middleware
+
+`@react-native/dev-middleware` is designed for integrators such as [`@expo/dev-server`](https://www.npmjs.com/package/@expo/dev-server) and [`@react-native/community-cli-plugin`](https://github.com/facebook/react-native/tree/main/packages/community-cli-plugin). It provides a common default implementation for core React Native dev server responsibilities.
+
+We intend to keep this to a narrow set of functionality, based around:
+
+- **Debugging** — The [Chrome DevTools protocol (CDP)](https://chromedevtools.github.io/devtools-protocol/) endpoints supported by React Native, including the Inspector Proxy, which facilitates connections with multiple devices.
+- **Dev actions** — Endpoints implementing core [Dev Menu](https://reactnative.dev/docs/debugging#accessing-the-dev-menu) actions, e.g. reloading the app, opening the debugger frontend.
+
+### HTTP endpoints
+
+<small>`DevMiddlewareAPI.middleware`</small>
+
+These are exposed as a [`connect`](https://www.npmjs.com/package/connect) middleware handler, assignable to `Metro.runServer` or other compatible HTTP servers.
+
+#### GET `/json/list`, `/json` ([CDP](https://chromedevtools.github.io/devtools-protocol/#endpoints))
+
+Returns the list of available WebSocket targets for all connected React Native app sessions.
+
+#### GET `/json/version` ([CDP](https://chromedevtools.github.io/devtools-protocol/#endpoints))
+
+Returns version metadata used by Chrome DevTools.
+
+#### GET `/debugger-frontend`
+
+Subpaths of this endpoint are reserved to serve the JavaScript debugger frontend.
+
+#### POST `/open-debugger`
+
+Open the JavaScript debugger for a given CDP target (direct Hermes debugging).
+
+<details>
+<summary>Example</summary>
+
+    curl -X POST 'http://localhost:8081/open-debugger?appId=com.meta.RNTester'
+</details>
+
+### WebSocket endpoints
+
+<small>`DevMiddlewareAPI.websocketEndpoints`</small>
+
+#### `/inspector/device`
+
+WebSocket handler for registering device connections.
+
+#### `/inspector/debug`
+
+WebSocket handler that proxies CDP messages to/from the corresponding device.
+
+## Contributing
+
+Changes to this package can be made locally and tested against the `rn-tester` app, per the [Contributing guide](https://reactnative.dev/contributing/overview#contributing-code). During development, this package is automatically run from source with no build step.

+
+
+
+A tiny node.js debugging utility modelled after node core's debugging technique.
+
+**Discussion around the V3 API is under way [here](https://github.com/visionmedia/debug/issues/370)**
+
+## 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_:
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %s', 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_:
+
+```js
+var debug = require('debug')('worker');
+
+setInterval(function(){
+  debug('doing some work');
+}, 1000);
+```
+
+ The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
+
+  ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
+
+  ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
+
+#### Windows note
+
+ On Windows the environment variable is set using the `set` command.
+
+ ```cmd
+ set DEBUG=*,-not_this
+ ```
+
+ Note that PowerShell uses different syntax to set environment variables.
+
+ ```cmd
+ $env:DEBUG = "*,-not_this"
+  ```
+
+Then, run the program to be debugged as usual.
+
+## 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.
+
+  ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
+
+  When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
+
+  ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.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".
+
+## 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_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);
+```
+
+#### Web Inspector Colors
+
+  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).
+
+  Colored output looks something like:
+
+  ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png)
+
+
+## Output streams
+
+  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example _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');
+```

+[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
+[![Slack Channel](http://zeit-slackin.now.sh/badge.svg)](https://zeit.chat/)
+
+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
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [node](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 ms is returned.
+
+## 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 will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+# open
+
+> Open stuff like URLs, files, executables. Cross-platform.
+
+This is meant to be used in command-line tools and scripts, not in the browser.
+
+If you need this for Electron, use [`shell.openPath()`](https://www.electronjs.org/docs/api/shell#shellopenpathpath) instead.
+
+Note: The original [`open` package](https://github.com/pwnall/node-open) was previously deprecated in favor of this package, and we got the name, so this package is now named `open` instead of `opn`. If you're upgrading from the original `open` package (`open@0.0.5` or lower), keep in mind that the API is different.
+
+#### Why?
+
+- Actively maintained.
+- Supports app arguments.
+- Safer as it uses `spawn` instead of `exec`.
+- Fixes most of the open original `node-open` issues.
+- Includes the latest [`xdg-open` script](https://cgit.freedesktop.org/xdg/xdg-utils/commit/?id=c55122295c2a480fa721a9614f0e2d42b2949c18) for Linux.
+- Supports WSL paths to Windows apps.
+
+## Install
+
+```
+$ npm install open
+```
+
+## Usage
+
+```js
+const open = require('open');
+
+(async () => {
+	// Opens the image in the default image viewer and waits for the opened app to quit.
+	await open('unicorn.png', {wait: true});
+	console.log('The image viewer app quit');
+
+	// Opens the URL in the default browser.
+	await open('https://sindresorhus.com');
+
+	// Opens the URL in a specified browser.
+	await open('https://sindresorhus.com', {app: 'firefox'});
+
+	// Specify app arguments.
+	await open('https://sindresorhus.com', {app: ['google chrome', '--incognito']});
+})();
+```
+
+## API
+
+It uses the command `open` on macOS, `start` on Windows and `xdg-open` on other platforms.
+
+### open(target, options?)
+
+Returns a promise for the [spawned child process](https://nodejs.org/api/child_process.html#child_process_class_childprocess). You would normally not need to use this for anything, but it can be useful if you'd like to attach custom event listeners or perform other operations directly on the spawned process.
+
+#### target
+
+Type: `string`
+
+The thing you want to open. Can be a URL, file, or executable.
+
+Opens in the default app for the file type. For example, URLs opens in your default browser.
+
+#### options
+
+Type: `object`
+
+##### wait
+
+Type: `boolean`\
+Default: `false`
+
+Wait for the opened app to exit before fulfilling the promise. If `false` it's fulfilled immediately when opening the app.
+
+Note that it waits for the app to exit, not just for the window to close.
+
+On Windows, you have to explicitly specify an app for it to be able to wait.
+
+##### background <sup>(macOS only)</sup>
+
+Type: `boolean`\
+Default: `false`
+
+Do not bring the app to the foreground.
+
+##### app
+
+Type: `string | string[]`
+
+Specify the app to open the `target` with, or an array with the app and app arguments.
+
+The app name is platform dependent. Don't hard code it in reusable modules. For example, Chrome is `google chrome` on macOS, `google-chrome` on Linux and `chrome` on Windows.
+
+You may also pass in the app's full path. For example on WSL, this can be `/mnt/c/Program Files (x86)/Google/Chrome/Application/chrome.exe` for the Windows installation of Chrome.
+
+##### url
+
+Type: `boolean`\
+Default: `false`
+
+Uses `URL` to encode the target before executing it.<br>
+We do not recommend using it on targets that are not URLs.
+
+Especially useful when dealing with the [double-quotes on Windows](#double-quotes-on-windows) caveat.
+
+##### allowNonzeroExitCode
+
+Type: `boolean`\
+Default: `false`
+
+Allow the opened app to exit with nonzero exit code when the `wait` option is `true`.
+
+We do not recommend setting this option. The convention for success is exit code zero.
+
+## Caveats
+
+### Double-quotes on Windows
+
+TL;DR: All double-quotes are stripped from the `target` and do not get to your desired destination (on Windows!).
+
+Due to specific behaviors of Window's Command Prompt (`cmd.exe`) regarding ampersand (`&`) characters breaking commands and URLs, double-quotes are now a special case.
+
+The solution ([#146](https://github.com/sindresorhus/open/pull/146)) to this and other problems was to leverage the fact that `cmd.exe` interprets a double-quoted argument as a plain text argument just by quoting it (like Node.js already does). Unfortunately, `cmd.exe` can only do **one** of two things: handle them all **OR** not handle them at all. As per its own documentation:
+
+>*If /C or /K is specified, then the remainder of the command line after the switch is processed as a command line, where the following logic is used to process quote (") characters:*
+>
+>    1.  *If all of the following conditions are met, then quote characters on the command line are preserved:*
+>        - *no /S switch*
+>        - *exactly two quote characters*
+>        - *no special characters between the two quote characters, where special is one of: &<>()@^|*
+>        - *there are one or more whitespace characters between the two quote characters*
+>        - *the string between the two quote characters is the name of an executable file.*
+>
+>    2.  *Otherwise, old behavior is to see if the first character is a quote character and if so, strip the leading character and remove the last quote character on the command line, preserving any text after the last quote character.*
+
+The option that solved all of the problems was the second one, and for additional behavior consistency we're also now using the `/S` switch, so we **always** get the second option. The caveat is that this built-in double-quotes handling ends up stripping all of them from the command line and so far we weren't able to find an escaping method that works (if you do, please feel free to contribute!).
+
+To make this caveat somewhat less impactful (at least for URLs), check out the [url option](#url). Double-quotes will be "preserved" when using it with an URL.

+[![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 docs for the ws classes.
+
+## 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 = new 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 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);
+```
+
+### Server broadcast
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+// Broadcast to all.
+wss.broadcast = function broadcast(data) {
+  wss.clients.forEach(function each(client) {
+    if (client.readyState === WebSocket.OPEN) {
+      client.send(data);
+    }
+  });
+};
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(data) {
+    // Broadcast to everyone else.
+    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);
+});
+```
+
+### Other examples
+
+For a full example with a browser client communicating with a ws server, see the
+examples folder.
+
+Otherwise, see the test cases.
+
+## Error handling best practices
+
+```js
+// If the WebSocket is closed before the following send is attempted
+ws.send('something');
+
+// Errors (both immediate and async write errors) can be detected in an optional
+// callback. The callback is also the only way of being notified that data has
+// actually been sent.
+ws.send('something', function ack(error) {
+  // If error is not defined, the send has been completed, otherwise the error
+  // object will indicate what failed.
+});
+
+// Immediate errors can also be handled with `try...catch`, but **note** that
+// since sends are inherently asynchronous, socket write failures will *not* be
+// captured when this technique is used.
+try {
+  ws.send('something');
+} catch (e) {
+  /* handle error */
+}
+```
+
+## 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.connection.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);
+```
+
+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()` and not `WebSocket#close()`. 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][].
