1.WebSocket Basics
WebSockets enable bidirectional communication.
2.Server Setup
const io = require('socket.io')(server);
io.on('connection', (socket) => {
console.log('User connected');
socket.on('message', (data) => {
io.emit('message', data);
});
socket.on('disconnect', () => {
console.log('User disconnected');
});
});
3.Client Integration
import io from 'socket.io-client';
const socket = io('http://localhost:3000');
socket.on('message', (data) => {
console.log(data);
});
socket.emit('message', { text: 'Hello' });
