+# webpack-dev-server
+
+Use [webpack](https://webpack.js.org) with a development server that provides
+live reloading. This should be used for **development only**.
+
+It uses [webpack-dev-middleware][middleware-url] under the hood, which provides
+fast in-memory access to the webpack assets.

+
+## Getting Started
+
+First things first, install the module:
+
+```console
+npm install webpack-dev-server --save-dev
+```
+
+or
+
+```console
+yarn add -D webpack-dev-server
+```
+
+or
+
+```console
+pnpm add -D webpack-dev-server
+```
+
+_Note: While you can install and run webpack-dev-server globally, we recommend
+installing it locally. webpack-dev-server will always use a local installation
+over a global one._
+
+## Usage
+
+There are two main, recommended methods of using the module:
+
+### With the CLI
+
+The easiest way to use it is with the [webpack CLI](https://webpack.js.org/api/cli/). In the directory where your
+`webpack.config.js` is, run:
+
+```console
+npx webpack serve
+```
+
+Following options are available with `webpack serve`:
+
+```

+### With NPM Scripts
+
+NPM package.json scripts are a convenient and useful means to run locally installed
+binaries without having to be concerned about their full paths. Simply define a
+script as such:
+
+```json
+{
+  "scripts": {
+    "serve": "webpack serve"
+  }
+}
+```
+
+And run the following in your terminal/console:
+
+```console
+npm run serve
+```
+
+NPM will automatically refer to the the binary in `node_modules` for you, and
+execute the file or command.
+
+### With the API
+
+While it's recommended to run webpack-dev-server via the CLI, you may also choose to start a server via the API.
+
+See the related [API documentation for `webpack-dev-server`](https://webpack.js.org/api/webpack-dev-server/).
+
+### With TypeScript
+
+If you use TypeScript in the webpack config, you'll need to properly type `devServer` property in order to avoid TS errors (e.g. `'devServer' does not exist in type 'Configuration'`). For that use either:
+
+```ts
+/// <reference path="node_modules/webpack-dev-server/types/lib/Server.d.ts"/>
+import type { Configuration } from "webpack";
+
+// Your logic
+```
+
+Or you can import the type from `webpack-dev-server`, i.e.
+
+```ts
+import type { Configuration as DevServerConfiguration } from "webpack-dev-server";
+import type { Configuration } from "webpack";
+
+const devServer: DevServerConfiguration = {};
+const config: Configuration = { devServer };
+
+// module.exports
+export default config;
+```
+
+### The Result
+
+Either method will start a server instance and begin listening for connections
+from `localhost` on port `8080`.
+
+webpack-dev-server is configured by default to support live-reload of files as
+you edit your assets while the server is running.
+
+See [**the documentation**][docs-url] for more use cases and options.
+
+## Browser Support
+
+While `webpack-dev-server` transpiles the client (browser) scripts to an ES5
+state, the project only officially supports the _last two versions of major
+browsers_. We simply don't have the resources to support every whacky
+browser out there.
+
+If you find a bug with an obscure / old browser, we would actively welcome a
+Pull Request to resolve the bug.
+
+## Support
+
+We do our best to keep issues in the repository focused on bugs, features, and
+needed modifications to the code for the module. Because of that, we ask users
+with general support, "how-to", or "why isn't this working" questions to try one
+of the other support channels that are available.
+
+Your first-stop-shop for support for webpack-dev-server should be the excellent
+[documentation][docs-url] for the module. If you see an opportunity for improvement
+of those docs, please head over to the [webpack.js.org repo][wjo-url] and open a
+pull request.
+
+From there, we encourage users to visit the [webpack Gitter chat][chat-url] and
+talk to the fine folks there. If your quest for answers comes up dry in chat,
+head over to [StackOverflow][stack-url] and do a quick search or open a new
+question. Remember; It's always much easier to answer questions that include your
+`webpack.config.js` and relevant files!
+
+If you're twitter-savvy you can tweet [#webpack][hash-url] with your question
+and someone should be able to reach out and lend a hand.
+
+If you have discovered a :bug:, have a feature suggestion, or would like to see
+a modification, please feel free to create an issue on Github. _Note: The issue
+template isn't optional, so please be sure not to remove it, and please fill it
+out completely._

+# ws: a Node.js WebSocket library
+
+[![Version npm](https://img.shields.io/npm/v/ws.svg?logo=npm)](https://www.npmjs.com/package/ws)
+[![CI](https://img.shields.io/github/actions/workflow/status/websockets/ws/ci.yml?branch=master&label=CI&logo=github)](https://github.com/websockets/ws/actions?query=workflow%3ACI+branch%3Amaster)
+[![Coverage Status](https://img.shields.io/coveralls/websockets/ws/master.svg?logo=coveralls)](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 backend 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
+
+[bufferutil][] is an optional module that can be installed alongside the ws
+module:
+
+```
+npm install --save-optional bufferutil
+```
+
+This is a binary addon that improves the performance of certain operations such
+as masking and unmasking the data payload of the WebSocket frames. Prebuilt
+binaries are available for the most popular platforms, so you don't necessarily
+need to have a C++ compiler installed on your machine.
+
+To force ws to not use bufferutil, use the
+[`WS_NO_BUFFER_UTIL`](./doc/ws.md#ws_no_buffer_util) environment variable. This
+can be useful to enhance security in systems where a user can put a package in
+the package search path of an application of another user, due to how the
+Node.js resolver algorithm works.
+
+#### Legacy opt-in for performance
+
+If you are running on an old version of Node.js (prior to v18.14.0), ws also
+supports the [utf-8-validate][] module:
+
+```
+npm install --save-optional utf-8-validate
+```
+
+This contains a binary polyfill for [`buffer.isUtf8()`][].
+
+To force ws not to use utf-8-validate, use the
+[`WS_NO_UTF_8_VALIDATE`](./doc/ws.md#ws_no_utf_8_validate) environment variable.
+
+## 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
+import WebSocket, { WebSocketServer } from 'ws';
+
+const wss = new WebSocketServer({
+  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 if context takeover is disabled.
+  }
+});
+```
+
+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
+import WebSocket from 'ws';
+
+const ws = new WebSocket('ws://www.host.com/path', {
+  perMessageDeflate: false
+});
+```
+
+## Usage examples
+
+### Sending and receiving text data
+
+```js
+import WebSocket from 'ws';
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('error', console.error);
+
+ws.on('open', function open() {
+  ws.send('something');
+});
+
+ws.on('message', function message(data) {
+  console.log('received: %s', data);
+});
+```
+
+### Sending binary data
+
+```js
+import WebSocket from 'ws';
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('error', console.error);
+
+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
+import { WebSocketServer } from 'ws';
+
+const wss = new WebSocketServer({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('error', console.error);
+
+  ws.on('message', function message(data) {
+    console.log('received: %s', data);
+  });
+
+  ws.send('something');
+});
+```
+
+### External HTTP/S server
+
+```js
+import { createServer } from 'https';
+import { readFileSync } from 'fs';
+import { WebSocketServer } from 'ws';
+
+const server = createServer({
+  cert: readFileSync('/path/to/cert.pem'),
+  key: readFileSync('/path/to/key.pem')
+});
+const wss = new WebSocketServer({ server });
+
+wss.on('connection', function connection(ws) {
+  ws.on('error', console.error);
+
+  ws.on('message', function message(data) {
+    console.log('received: %s', data);
+  });
+
+  ws.send('something');
+});
+
+server.listen(8080);
+```
+
+### Multiple servers sharing a single HTTP/S server
+
+```js
+import { createServer } from 'http';
+import { WebSocketServer } from 'ws';
+
+const server = createServer();
+const wss1 = new WebSocketServer({ noServer: true });
+const wss2 = new WebSocketServer({ noServer: true });
+
+wss1.on('connection', function connection(ws) {
+  ws.on('error', console.error);
+
+  // ...
+});
+
+wss2.on('connection', function connection(ws) {
+  ws.on('error', console.error);
+
+  // ...
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+  const { pathname } = new URL(request.url, 'wss://base.url');
+
+  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
+import { createServer } from 'http';
+import { WebSocketServer } from 'ws';
+
+function onSocketError(err) {
+  console.error(err);
+}
+
+const server = createServer();
+const wss = new WebSocketServer({ noServer: true });
+
+wss.on('connection', function connection(ws, request, client) {
+  ws.on('error', console.error);
+
+  ws.on('message', function message(data) {
+    console.log(`Received message ${data} from user ${client}`);
+  });
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+  socket.on('error', onSocketError);
+
+  // This function is not defined on purpose. Implement it with your own logic.
+  authenticate(request, function next(err, client) {
+    if (err || !client) {
+      socket.write('HTTP/1.1 401 Unauthorized\r\n\r\n');
+      socket.destroy();
+      return;
+    }
+
+    socket.removeListener('error', onSocketError);
+
+    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
+import WebSocket, { WebSocketServer } from 'ws';
+
+const wss = new WebSocketServer({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('error', console.error);
+
+  ws.on('message', function message(data, isBinary) {
+    wss.clients.forEach(function each(client) {
+      if (client.readyState === WebSocket.OPEN) {
+        client.send(data, { binary: isBinary });
+      }
+    });
+  });
+});
+```
+
+A client WebSocket broadcasting to every other connected WebSocket clients,
+excluding itself.
+
+```js
+import WebSocket, { WebSocketServer } from 'ws';
+
+const wss = new WebSocketServer({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('error', console.error);
+
+  ws.on('message', function message(data, isBinary) {
+    wss.clients.forEach(function each(client) {
+      if (client !== ws && client.readyState === WebSocket.OPEN) {
+        client.send(data, { binary: isBinary });
+      }
+    });
+  });
+});
+```
+
+### Round-trip time
+
+```js
+import WebSocket from 'ws';
+
+const ws = new WebSocket('wss://websocket-echo.com/');
+
+ws.on('error', console.error);
+
+ws.on('open', function open() {
+  console.log('connected');
+  ws.send(Date.now());
+});
+
+ws.on('close', function close() {
+  console.log('disconnected');
+});
+
+ws.on('message', function message(data) {
+  console.log(`Round-trip time: ${Date.now() - data} ms`);
+
+  setTimeout(function timeout() {
+    ws.send(Date.now());
+  }, 500);
+});
+```
+
+### Use the Node.js streams API
+
+```js
+import WebSocket, { createWebSocketStream } from 'ws';
+
+const ws = new WebSocket('wss://websocket-echo.com/');
+
+const duplex = createWebSocketStream(ws, { encoding: 'utf8' });
+
+duplex.on('error', console.error);
+
+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
+import { WebSocketServer } from 'ws';
+
+const wss = new WebSocketServer({ port: 8080 });
+
+wss.on('connection', function connection(ws, req) {
+  const ip = req.socket.remoteAddress;
+
+  ws.on('error', console.error);
+});
+```
+
+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(',')[0].trim();
+
+  ws.on('error', console.error);
+});
+```
+
+### 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
+import { WebSocketServer } from 'ws';
+
+function heartbeat() {
+  this.isAlive = true;
+}
+
+const wss = new WebSocketServer({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.isAlive = true;
+  ws.on('error', console.error);
+  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();
+  });
+}, 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
+import WebSocket from '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://websocket-echo.com/');
+
+client.on('error', console.error);
+client.on('open', heartbeat);
+client.on('ping', heartbeat);
+client.on('close', function clear() {
+  clearTimeout(this.pingTimeout);
+});
+```
