We will also create a new adapter based on [Redis Streams](https://redis.io/docs/data-types/streams/), which will support this feature. Added in [54d5ee0](https://togithub.com/socketio/socket.io/commit/54d5ee05a684371191e207b8089f09fc24eb5107). ##### Compatibility (for real) with Express middlewares This feature implements middlewares at the Engine.IO level, because Socket.IO middlewares are meant for namespace authorization and are not executed during a classic HTTP request/response cycle. Syntax: ```js io.engine.use((req, res, next) => { // do something next(); }); // with express-session import session from "express-session"; io.engine.use(session({ secret: "keyboard cat", resave: false, saveUninitialized: true, cookie: { secure: true } })); // with helmet import helmet from "helmet"; io.engine.use(helmet()); ``` A workaround was possible by using the allowRequest option and the "headers" event, but this feels way cleaner and works with upgrade requests too. Added in [24786e7](https://togithub.com/socketio/engine.io/commit/24786e77c5403b1c4b5a2bc84e2af06f9187f74a). ##### Error details in the disconnecting and disconnect events The `disconnect` event will now contain additional details about the disconnection reason. ```js io.on("connection", (socket) => { socket.on("disconnect", (reason, description) => { console.log(description); }); }); ``` Added in [8aa9499](https://togithub.com/socketio/socket.io/commit/8aa94991cee5518567d6254eec04b23f81510257). ##### Automatic removal of empty child namespaces This commit adds a new option, "cleanupEmptyChildNamespaces". With this option enabled (disabled by default), when a socket disconnects from a dynamic namespace and if there are no other sockets connected to it then the namespace will be cleaned up and its adapter will be closed. ```js import { createServer } from "node:http"; import { Server } from "socket.io"; const httpServer = createServer(); const io = new Server(httpServer, { cleanupEmptyChildNamespaces: true }); ``` Added in [5d9220b](https://togithub.com/socketio/socket.io/commit/5d9220b69adf73e086c27bbb63a4976b348f7c4c). ##### A new "addTrailingSlash" option The trailing slash which was added by default can now be disabled: ```js import { createServer } from "node:http"; import { Server } from "socket.io"; const httpServer = createServer(); const io = new Server(httpServer, { addTrailingSlash: false }); ``` In the example above, the clients can omit the trailing slash and use `/socket.io` instead of `/socket.io/`.

the Socket#use() method is removed (see [5c73733](https://togithub.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("connection", 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. ### [`v2.5.1`](https://togithub.com/socketio/socket.io/releases/tag/2.5.1) [Compare Source](https://togithub.com/socketio/socket.io/compare/2.5.0...2.5.1) ##### Bug Fixes - add a noop handler for the error event ([d30630b](https://togithub.com/socketio/socket.io/commit/d30630ba10562bf987f4d2b42440fc41a828119c)) ##### Links: - Diff: https://github.com/socketio/socket.io/compare/2.5.0...2.5.1 - Client release: `-` - engine.io version: `~3.6.0` (no change) - ws version: `~7.5.10` ### [`v2.5.0`](https://togithub.com/socketio/socket.io/blob/HEAD/CHANGELOG.md#250-2022-06-26) [Compare Source](https://togithub.com/socketio/socket.io/compare/2.4.1...2.5.0) ⚠️ WARNING ⚠️ The default value of the `maxHttpBufferSize` option has been decreased from 100 MB to 1 MB, in order to prevent attacks by denial of service.

You can still use `uws` by running `npm install uws --save` in your project and using the `wsEngine` option: ```js var engine = require('engine.io'); var server = engine.listen(3000, { wsEngine: 'uws' }); ``` - `pingTimeout` now defaults to 5 seconds (instead of 60 seconds): [https://github.com/socketio/engine.io/pull/551](https://togithub.com/socketio/engine.io/pull/551) ### [`v2.0.4`](https://togithub.com/socketio/socket.io/releases/tag/2.0.4) [Compare Source](https://togithub.com/socketio/socket.io/compare/2.0.3...2.0.4) #### Bug fixes - do not throw when receiving an unhandled error packet ([#​3038](https://togithub.com/socketio/socket.io/issues/3038)) - reset rooms object before broadcasting from namespace ([#​3039](https://togithub.com/socketio/socket.io/issues/3039)) ##### Links: - Milestone: [2.0.4](https://togithub.com/socketio/socket.io/milestone/13) - Diff: [2.0.3...2.0.4](https://togithub.com/socketio/socket.io/compare/2.0.3...2.0.4) - Client release: [2.0.4](https://togithub.com/socketio/socket.io-client/releases/tag/2.0.4) - Diff `engine.io`: - - Diff `ws`: - ### [`v2.0.3`](https://togithub.com/socketio/socket.io/releases/tag/2.0.3) [Compare Source](https://togithub.com/socketio/socket.io/compare/2.0.2...2.0.3) #### Bug fixes - reset rooms object before broadcasting ([#​2970](https://togithub.com/socketio/socket.io/issues/2970)) - fix middleware initialization ([#​2969](https://togithub.com/socketio/socket.io/issues/2969)) ##### Links: - Milestone: [2.0.3](https://togithub.com/socketio/socket.io/milestone/12) - Diff: [2.0.2...2.0.3](https://togithub.com/socketio/socket.io/compare/2.0.2...2.0.3) - Client release: [2.0.3](https://togithub.com/socketio/socket.io-client/releases/tag/2.0.3) - Diff `engine.io`: - - Diff `ws`: - ### [`v2.0.2`](https://togithub.com/socketio/socket.io/releases/tag/2.0.2) [Compare Source](https://togithub.com/socketio/socket.io/compare/2.0.1...2.0.2) #### Bug fixes - fix timing issues with middleware ([#​2948](https://togithub.com/socketio/socket.io/issues/2948)) ##### Links: - Milestone: [2.0.2](https://togithub.com/socketio/socket.io/milestone/11) - Diff: [2.0.1...2.0.2](https://togithub.com/socketio/socket.io/compare/2.0.1...2.0.2) - Client release: [2.0.2](https://togithub.com/socketio/socket.io-client/releases/tag/2.0.2) - Diff `engine.io`: - - Diff `ws`: - ### [`v2.0.1`](https://togithub.com/socketio/socket.io/releases/tag/2.0.1) [Compare Source](https://togithub.com/socketio/socket.io/compare/2.0.0...2.0.1) #### Bug fixes \- update path of client file ([#​2934](https://togithub.com/socketio/socket.io/issues/2934)) ##### Links: - Milestone: [2.0.1](https://togithub.com/socketio/socket.io/milestone/9) - Diff: [2.0.0...2.0.1](https://togithub.com/socketio/socket.io/compare/2.0.0...2.0.1) - Client release: [2.0.1](https://togithub.com/socketio/socket.io-client/releases/tag/2.0.1) - Diff `engine.io`: - - Diff `ws`: - ### [`v2.0.0`](https://togithub.com/socketio/socket.io/releases/tag/2.0.0) [Compare Source](https://togithub.com/socketio/socket.io/compare/1.7.4...2.0.0) This major release brings several performance improvements: - [uws](https://togithub.com/uWebSockets/uWebSockets) is now the default Websocket engine. It should bring significant improvement in performance (particularly in terms of memory consumption) (https://github.com/socketio/engine.io/releases/tag/2.0.0) - the Engine.IO and Socket.IO handshake packets were merged, reducing the number of roundtrips necessary to establish a connection. ([#​2833](https://togithub.com/socketio/socket.io/issues/2833)) - it is now possible to provide a custom parser according to the needs of your application ([#​2829](https://togithub.com/socketio/socket.io/issues/2829)). Please take a look at the [example](https://togithub.com/socketio/socket.io/tree/master/examples/custom-parsers) for more information. Please note that this release is not backward-compatible, due to: - a breaking change related to utf-8 encoding in engine.io-parser ([https://github.com/socketio/engine.io-parser/pull/81](https://togithub.com/socketio/engine.io-parser/pull/81)) - an update to make the socket id on the client match the id on the server-side ([https://github.com/socketio/socket.io-client/pull/1058](https://togithub.com/socketio/socket.io-client/pull/1058)) Please also note that if you are using a self-signed certificate, `rejectUnauthorized` now defaults to `true` ([https://github.com/socketio/engine.io-client/pull/558](https://togithub.com/socketio/engine.io-client/pull/558)). Finally, the API documentation is now in the repository ([here](https://togithub.com/socketio/socket.io/blob/master/docs/API.md)), and the content of the website [here](https://togithub.com/socketio/socket.io-website).
