  Features

  Support for WebTransport

  The Socket.IO server can now use WebTransport as the underlying transport.

  WebTransport is a web API that uses the HTTP/3 protocol as a bidirectional transport. It's intended for two-way communications between a web client and an HTTP/3 server.

  References:

  • https://w3c.github.io/webtransport/
  • https://developer.mozilla.org/en-US/docs/Web/API/WebTransport
  • https://developer.chrome.com/articles/webtransport/

  Until WebTransport support lands in Node.js, you can use the @ fails-components/webtransport package:

  https://w3c.github.io/webtransport/#custom-certificate-requirements)
  const cert = readFileSync("/path/to/my/cert.pem");
  const key = readFileSync("/path/to/my/key.pem");

  const httpsServer = createServer({
  key,
  cert
  });

  httpsServer.listen(3000);

  const io = new Server(httpsServer, {
  transports: ["polling", "websocket", "webtransport"] // WebTransport is not enabled by default
  });

  const h3Server = new Http3Server({
  port: 3000,
  host: "0.0.0.0",
  secret: "changeit",
  cert,
  privKey: key,
  });

  (async () => {
  const stream = await h3Server.sessionStream("/socket.io/");
  const sessionReader = stream.getReader();

  while (true) {
  const { done, value } = await sessionReader.read();
  if (done) {
  break;
  }
  io.engine.onWebTransportSession(value);
  }
  })();

  h3Server.startServer();">

  import { readFileSync } from "fs";
  
  import { createServer } from "https";
  
  import { Server } from "socket.io";
  
  import { Http3Server } from "@ fails-components/webtransport";
  
  // WARNING: the total length of the validity period MUST NOT exceed two weeks (https://w3c.github.io/webtransport/#custom-certificate-requirements)
  
  const cert = readFileSync("/path/to/my/cert.pem");
  
  const key = readFileSync("/path/to/my/key.pem");
  const httpsServer = createServer({
  
  key,
  
  cert
  
  });
  httpsServer.listen(3000);
  const io = new Server(httpsServer, {
  
  transports: ["polling", "websocket", "webtransport"] // WebTransport is not enabled by default
  
  });
  const h3Server = new Http3Server({
  
  port: 3000,
  
  host: "0.0.0.0",
  
  secret: "changeit",
  
  cert,
  
  privKey: key,
  
  });
  (async () => {
  
  const stream = await h3Server.sessionStream("/socket.io/");
  
  const sessionReader = stream.getReader();
  while (true) {
  
  const { done, value } = await sessionReader.read();
  
  if (done) {
  
  break;
  
  }
  
  io.engine.onWebTransportSession(value);
  
  }
  
  })();
  h3Server.startServer();

  Bug Fixes

  • add timeout method to remote socket (#4558) (0c0eb00)
  • typings: properly type emits with timeout (f3ada7d)

  Features

  Promise-based acknowledgements

  This commit adds some syntactic sugar around acknowledgements:

  • emitWithAck()
  try {
  const responses = await io.timeout(1000).emitWithAck("some-event");
  console.log(responses); // one response per client
  } catch (e) {
  // some clients did not acknowledge the event in the given delay
  }

  io.on("connection", async (socket) => {
  // without timeout
  const response = await socket.emitWithAck("hello", "world");

  // with a specific timeout
  try {
  const response = await socket.timeout(1000).emitWithAck("hello", "world");
  } catch (err) {
  // the client did not acknowledge the event in the given delay
  }
  });

  • serverSideEmitWithAck()

  try {
    const responses = await io.timeout(1000).serverSideEmitWithAck("some-event");
    console.log(responses); // one response per server (except itself)
  } catch (e) {
    // some servers did not acknowledge the event in the given delay
  }

  Added in 184f3cf.

  Connection state recovery

  This feature allows a client to reconnect after a temporary disconnection and restore its state:

  • id
  • rooms
  • data
  • missed packets

  Usage:

  import { Server } from "socket.io";

  const io = new Server({
  connectionStateRecovery: {
  // default values
  maxDisconnectionDuration: 2 60 1000,
  skipMiddlewares: true,
  },
  });

  io.on("connection", (socket) => {
  console.log(socket.recovered); // whether the state was recovered or not
  });

  Here's how it works:

  • the server sends a session ID during the handshake (which is different from the current id attribute, which is public and can be freely shared)
  • the server also includes an offset in each packet (added at the end of the data array, for backward compatibility)
  • upon temporary disconnection, the server stores the client state for a given delay (implemented at the adapter level)
  • upon reconnection, the client sends both the session ID and the last offset it has processed, and the server tries to restore the state

  The in-memory adapter already supports this feature, and we will soon update the Postgres and MongoDB adapters. We will also create a new adapter based on Redis Streams, which will support this feature.

  Added in 54d5ee0.

  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:

  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.

  Error details in the disconnecting and disconnect events

  The disconnect event will now contain additional details about the disconnection reason.

  io.on("connection", (socket) => {
    socket.on("disconnect", (reason, description) => {
      console.log(description);
    });
  });

  Added in 8aa9499.

  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.

  import { createServer } from "node:http";
  import { Server } from "socket.io";

  const httpServer = createServer();
  const io = new Server(httpServer, {
  cleanupEmptyChildNamespaces: true
  });

  Added in 5d9220b.

  A new "addTrailingSlash" option

  The trailing slash which was added by default can now be disabled:

  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/.
