-### 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.

+# Socket.IO
 
-## Features
+Socket.IO is a Node.JS framework for making realtime applications.
 
-Socket.IO enables real-time bidirectional event-based communication. It consists of:
+It brings the best of WebSockets and other data transport mechanisms for
+blazing fast realtime data exchange in web browsers, mobile devices and
+servers.
 
-- 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)
+## How to Install
 
-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)
-- [Python](https://github.com/miguelgrinberg/python-socketio)
-- [.Net](https://github.com/Quobject/SocketIoClientDotNet)
-
-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://socket.io/docs/v3/client-api/#new-Manager-url-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
-// with npm
 npm install socket.io
-
-// with yarn
-yarn add socket.io
 ```
 
 ## How to use
 
-The following example attaches socket.io to a plain Node.JS
-HTTP server listening on port `3000`.
+First, require `socket.io` and attach it to a HTTP/HTTPS server:
 
 ```js
-const server = require('http').createServer();
-const io = require('socket.io')(server);
-io.on('connection', client => {
-  client.on('event', data => { /* … */ });
-  client.on('disconnect', () => { /* … */ });
+var app = express.createServer()
+  , io = require('socket.io')(app);
+
+app.listen(80);
+
+io.on('connection', function (socket) {
+  socket.emit('news', { hello: 'world' });
+  socket.on('my other event', function (data) {
+    console.log(data);
+  });
 });
-server.listen(3000);
 ```
 
-### Standalone
+Finally, load it from the client side code:
+
+```html
+<script src="/socket.io/socket.io.js"></script>
+<script>
+  var socket = io.connect('http://localhost');
+  socket.on('news', function (data) {
+    console.log(data);
+    socket.emit('my other event', { my: 'data' });
+  });
+</script>
+```
+
+For more thorough examples, look at the `examples/` directory.
+
+## Short recipes
+
+### Sending and receiving events.
+
+Socket.IO allows you to emit and receive custom events.
+Besides `connect`, `message` and `disconnect`, you can emit custom events:
 
 ```js
-const io = require('socket.io')();
-io.on('connection', client => { ... });
-io.listen(3000);
+// note, io(<port>) will create a http server for you
+var io = require('socket.io')(80);
+
+io.on('connection', function (socket) {
+  io.emit('this', { will: 'be received by everyone' });
+
+  socket.on('private message', function (from, msg) {
+    console.log('I received a private message by ', from, ' saying ', msg);
+  });
+
+  socket.on('disconnect', function () {
+    io.emit('user disconnected');
+  });
+});
 ```
 
-### In conjunction with Express
+### Storing data associated to a client
 
-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`.
+Sometimes it's necessary to store data associated with a client that's
+necessary for the duration of the session.
+
+#### Server side
 
 ```js
-const app = require('express')();
-const server = require('http').createServer(app);
-const io = require('socket.io')(server);
-io.on('connection', () => { /* … */ });
-server.listen(3000);
+var io = require('socket.io')(80);
+
+io.on('connection', function (socket) {
+  socket.on('set nickname', function (name) {
+    socket.set('nickname', name, function () { socket.emit('ready'); });
+  });
+
+  socket.on('msg', function () {
+    socket.get('nickname', function (err, name) {
+      console.log('Chat message by ', name);
+    });
+  });
+});
 ```
 
-### In conjunction with Koa
+#### Client side
 
-Like Express.JS, Koa works by exposing an application as a request
-handler function, but only by calling the `callback` method.
+```html
+<script>
+  var socket = io.connect('http://localhost');
+
+  socket.on('connect', function () {
+    socket.emit('set nickname', confirm('What is your nickname?'));
+    socket.on('ready', function () {
+      console.log('Connected !');
+      socket.emit('msg', confirm('What is your message?'));
+    });
+  });
+</script>
+```
+
+#### Client side
+
+In the client side, messages are received the same way whether they're volatile
+or not.
+
+### Getting acknowledgements
+
+Sometimes, you might want to get a callback when the client confirmed the message
+reception.
+
+To do this, simply pass a function as the last parameter of `.emit`.
+What's more, when you use `.emit`, the acknowledgement is done by you, which
+means you can also pass data along:
+
+#### Server side
 
 ```js
-const app = require('koa')();
-const server = require('http').createServer(app.callback());
-const io = require('socket.io')(server);
-io.on('connection', () => { /* … */ });
-server.listen(3000);
+var io = require('socket.io')(80);
+
+io.on('connection', function (socket) {
+  socket.on('ferret', function (name, fn) {
+    fn('woot');
+  });
+});
 ```
 
-### In conjunction with Fastify
+#### Client side
 
-To integrate Socket.io in your Fastify application you just need to
-register `fastify-socket.io` plugin. It will create a `decorator`
-called `io`.
+```html
+<script>
+  var socket = io.connect(); // TIP: .connect with no args does auto-discovery
+  socket.on('connect', function () { // TIP: you can avoid listening on `connect` and listen on events directly too!
+    socket.emit('ferret', 'tobi', function (data) {
+      console.log(data); // data will be 'woot'
+    });
+  });
+</script>
+```
+
+### Broadcasting messages
+
+To broadcast, simply add a `broadcast` flag to `emit` and `send` method calls.
+Broadcasting means sending a message to everyone else except for the socket
+that starts it.
+
+#### Server side
 
 ```js
-const app = require('fastify')();
-app.register(require('fastify-socket.io'));
-app.io.on('connection', () => { /* … */ });
-app.listen(3000);
+var io = require('socket.io')(80);
+
+io.on('connection', function (socket) {
+  socket.broadcast.emit('user connected');
+});
 ```
 
-## Documentation
+### Rooms
 
-Please see the documentation [here](https://socket.io/docs/).
+Sometimes you want to put certain sockets in the same room, so that it's easy
+to broadcast to all of them together.
 
-The source code of the website can be found [here](https://github.com/socketio/socket.io-website). Contributions are welcome!
+Think of this as built-in channels for sockets. Sockets `join` and `leave`
+rooms in each socket.
 
-## Debug / logging
+#### Server side
 
-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.
+```js
+var io = require('socket.io')(80);
 
-To see the output from all of Socket.IO's debugging scopes you can use:
-
-```
-DEBUG=socket.io* node myapp
+io.on('connection', function (socket) {
+  socket.join('justin bieber fans');
+  socket.broadcast.to('justin bieber fans').emit('new fan');
+  io.to('rammstein fans').emit('new non-fan');
+});
 ```
 
-## Testing
+### Using it just as a cross-browser WebSocket
 
+If you just want the WebSocket semantics, you can do that too.
+Simply leverage `send` and listen on the `message` event:
+
+#### Server side
+
+```js
+var io = require('socket.io')(80);
+
+io.on('connection', function (socket) {
+  socket.on('message', function () { });
+  socket.on('disconnect', function () { });
+});
 ```
-npm test
+
+#### Client side
+
+```html
+<script>
+  var socket = io.connect('http://localhost/');
+  socket.on('connect', function () {
+    socket.send('hi');
+
+    socket.on('message', function (msg) {
+      // my msg
+    });
+  });
+</script>
 ```
-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.
+### Messaging between clients
 
-The `gulp` task `test` will always transpile the source code into es5 and export to `dist` first before running the test.
+Each client joins its own group, identified by the client id, which means you
+can leverage `to` to message a particular client:
 
+```js
+var io = require('socket.io')(80);
+io.on('connection', function (socket) {
+  socket.on('salutate', function (id) {
+    io.to(id)
+      .emit('hi!')
+      .on('disconnect', function () {
+        socket.emit('friend disconnected');
+      });
+  });
+});
+```

-# Angular TodoMVC + Socket.IO
-
-This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 11.0.4.
-
-Inspired from the [TodoMVC](http://todomvc.com/) [angular example](https://github.com/tastejs/todomvc/tree/master/examples/angular2).
-
-![demo](assets/demo.gif)
-
-## Development server
-
-Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
-
-## Socket.IO server
-
-Run `npm run start:server` to start the Socket.IO server.
-
-## Code scaffolding
-
-Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
-
-## Build
-
-Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `--prod` flag for a production build.
-
-## Running unit tests
-
-Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
-
-## Running end-to-end tests
-
-Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
-
-## Further help
-
-To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page.

-# Socket.IO Chat with haproxy & redis
-
-A simple chat demo for socket.io
-
-## How to use
-
-Install [Docker Compose](https://docs.docker.com/compose/install/), then:
-
-```
-$ docker-compose up -d
-```
-
-And then point your browser to `http://localhost:3000`.
-
-This will start four Socket.IO nodes, behind a haproxy instance which will loadbalance the requests (using a cookie for sticky sessions, see [cookie](https://cbonte.github.io/haproxy-dconv/1.7/configuration.html#4.2-cookie)).
-
-Each node connects to the redis backend, which will enable to broadcast to every client, no matter which node it is currently connected to.
-
-```
-# you can kill a given node, the client should reconnect to another node
-$ docker-compose stop server-george
-```
-
-## Features
-
-- Multiple users can join a chat room by each entering a unique username
-on website load.
-- Users can type chat messages to the chat room.
-- A notification is sent to all users when a user joins or leaves
-the chatroom.

-# Socket.IO Chat with httpd & redis
-
-A simple chat demo for socket.io
-
-## How to use
-
-Install [Docker Compose](https://docs.docker.com/compose/install/), then:
-
-```
-$ docker-compose up -d
-```
-
-And then point your browser to `http://localhost:3000`.
-
-This will start four Socket.IO nodes, behind a httpd proxy which will loadbalance the requests (using a cookie for sticky sessions, see [cookie](http://httpd.apache.org/docs/2.4/fr/mod/mod_proxy_balancer.html)).
-
-Each node connects to the redis backend, which will enable to broadcast to every client, no matter which node it is currently connected to.
-
-```
-# you can kill a given node, the client should reconnect to another node
-$ docker-compose stop server-george
-```
-
-## Features
-
-- Multiple users can join a chat room by each entering a unique username
-on website load.
-- Users can type chat messages to the chat room.
-- A notification is sent to all users when a user joins or leaves
-the chatroom.

-# Socket.IO Chat with nginx & redis
-
-A simple chat demo for socket.io
-
-## How to use
-
-Install [Docker Compose](https://docs.docker.com/compose/install/), then:
-
-```
-$ docker-compose up -d
-```
-
-And then point your browser to `http://localhost:3000`.
-
-This will start four Socket.IO nodes, behind a nginx proxy which will loadbalance the requests (using the IP of the client, see [ip_hash](http://nginx.org/en/docs/http/ngx_http_upstream_module.html#ip_hash)).
-
-Each node connects to the redis backend, which will enable to broadcast to every client, no matter which node it is currently connected to.
-
-```
-# you can kill a given node, the client should reconnect to another node
-$ docker-compose stop server-george
-```
-
-A `client` container is included in the `docker-compose.yml` file, in order to test the routing.
-
-You can create additional `client` containers with:
-
-```
-$ docker-compose up -d --scale=client=10 client
-# and then
-$ docker-compose logs client
-```
-
-## Features
-
-- Multiple users can join a chat room by each entering a unique username
-on website load.
-- Users can type chat messages to the chat room.
-- A notification is sent to all users when a user joins or leaves
-the chatroom.

-# Socket.IO Chat with traefik & [redis](https://redis.io/)
-
-A simple chat demo for Socket.IO
-
-## How to use
-
-Install [Docker Compose](https://docs.docker.com/compose/install/), then:
-
-```
-$ docker-compose up -d
-```
-
-And then point your browser to `http://localhost:3000`.
-
-You can then scale the server to multiple instances:
-
-```
-$ docker-compose up -d --scale=server=7
-```
-
-The session stickiness, which is [required](https://socket.io/docs/v3/using-multiple-nodes/) when using multiple Socket.IO server instances, is achieved with a cookie. More information [here](https://doc.traefik.io/traefik/v2.0/routing/services/#sticky-sessions).
