// Install required dependencies:
// npm install express socket.io

// server.js
const express = require('express');
const app = express();
const http = require('http').Server(app);
const io = require('socket.io')(http);

// Serve the index.html file
app.get('/', (req, res) => {
  res.sendFile(__dirname + '/index.html');
});

// Socket.IO event handling
io.on('connection', (socket) => {
  console.log('A user connected.');

  // Handle a custom event 'chat message'
  socket.on('chat message', (msg) => {
    console.log('Message:', msg);
    io.emit('chat message', msg); // Broadcast the message to all connected clients
  });

  // Handle the 'disconnect' event
  socket.on('disconnect', () => {
    console.log('A user disconnected.');
  });
});

// Start the server 
const port = 3000;
http.listen(port, () => {
  console.log(`Server running on http://localhost:${port}`);
});
