ExpressJs — WebSockets for Real-Time Features

Add real-time capabilities like live chat, notifications, or tracking using WebSockets with libraries like Socket.IO.

const http = require('http');
const socketIo = require('socket.io');

const server = http.createServer(app);
const io = socketIo(server);

io.on('connection', socket => {
  console.log('New client connected');
  socket.on('message', msg => io.emit('message', msg));
});

server.listen(3000);
