Room Management

This feature allows you to manage rooms, which are arbitrary channels that sockets can join and leave. It enables you to emit events to all clients in a specific room.

const { Server } = require('socket.io');
const io = new Server();
io.on('connection', (socket) => {
  socket.join('some room');
  io.to('some room').emit('some event');
});

Namespace Management

Namespaces are a way to divide your clients into different endpoints or paths. This feature allows you to manage these namespaces, enabling targeted communication and organization.

const { Server } = require('socket.io');
const io = new Server();
const nsp = io.of('/my-namespace');
nsp.on('connection', (socket) => {
  console.log('someone connected to my-namespace');
});
nsp.emit('hi', 'everyone!');

Broadcasting Events

Broadcasting enables you to send a message to all connected clients except for the sender. This is useful for notifying all users about the actions of one.

const { Server } = require('socket.io');
const io = new Server();
io.on('connection', (socket) => {
  socket.broadcast.emit('broadcast', 'hello friends!');
});
