Socket.io Versions Save

Realtime application framework (Node.JS server)

4.5.3

1 year ago

Bug Fixes

  • typings: apply types to "io.timeout(...).emit()" calls (e357daf)

4.5.2

1 year ago

2.5.0

1 year ago

:warning: WARNING :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.

Security advisory: https://github.com/advisories/GHSA-j4f2-536g-r55m

Bug Fixes

  • fix race condition in dynamic namespaces (05e1278)
  • ignore packet received after disconnection (22d4bdf)
  • only set 'connected' to true after middleware execution (226cc16)
  • prevent the socket from joining a room after disconnection (f223178)

4.5.1

1 year ago

Bug Fixes

  • forward the local flag to the adapter when using fetchSockets() (30430f0)
  • typings: add HTTPS server to accepted types (#4351) (9b43c91)

4.5.0

2 years ago

Bug Fixes

  • typings: ensure compatibility with TypeScript 3.x (#4259) (02c87a8)

Features

  • add support for catch-all listeners for outgoing packets (531104d)

This is similar to onAny(), but for outgoing packets.

Syntax:

socket.onAnyOutgoing((event, ...args) => {
  console.log(event);
});
  • broadcast and expect multiple acks (8b20457)

Syntax:

io.timeout(1000).emit("some-event", (err, responses) => {
  // ...
});
  • add the "maxPayload" field in the handshake details (088dcb4)

So that clients in HTTP long-polling can decide how many packets they have to send to stay under the maxHttpBufferSize value.

This is a backward compatible change which should not mandate a new major revision of the protocol (we stay in v4), as we only add a field in the JSON-encoded handshake data:

0{"sid":"lv_VI97HAXpY6yYWAAAC","upgrades":["websocket"],"pingInterval":25000,"pingTimeout":5000,"maxPayload":1000000}

4.4.1

2 years ago

Bug Fixes

  • types: make RemoteSocket.data type safe (#4234) (770ee59)
  • types: pass SocketData type to custom namespaces (#4233) (f2b8de7)

4.4.0

2 years ago

Bug Fixes

  • only set 'connected' to true after middleware execution (02b0f73)

Features

  • add an implementation based on uWebSockets.js (c0d8c5a)
const { App } = require("uWebSockets.js");
const { Server } = require("socket.io");

const app = new App();
const io = new Server();

io.attachApp(app);

io.on("connection", (socket) => {
  // ...
});

app.listen(3000, (token) => {
  if (!token) {
    console.warn("port already in use");
  }
});

socket.timeout(5000).emit("my-event", (err) => {
  if (err) {
    // the client did not acknowledge the event in the given delay
  }
});

interface SocketData {
  name: string;
  age: number;
}

const io = new Server<ClientToServerEvents, ServerToClientEvents, InterServerEvents, SocketData>();

io.on("connection", (socket) => {
  socket.data.name = "john";
  socket.data.age = 42;
});
