Server-Side Socket Handling

This feature allows you to set up a Socket.IO server that listens for client connections and disconnections.

const io = require('socket.io')(3000);
io.on('connection', (socket) => {
  console.log('a user connected');
  socket.on('disconnect', () => {
    console.log('user disconnected');
  });
});

Client-Side Socket Handling

This feature allows you to set up a Socket.IO client that connects to a server and listens for connection and disconnection events.

const socket = io('http://localhost:3000');
socket.on('connect', () => {
  console.log('connected to server');
});
socket.on('disconnect', () => {
  console.log('disconnected from server');
});

Emitting and Listening to Events

This feature allows you to emit and listen to custom events between the server and client.

const io = require('socket.io')(3000);
io.on('connection', (socket) => {
  socket.on('chat message', (msg) => {
    io.emit('chat message', msg);
  });
});

const socket = io('http://localhost:3000');
socket.emit('chat message', 'Hello World');
socket.on('chat message', (msg) => {
  console.log('message: ' + msg);
});
