const app = require(‘express’)();
const http = require(‘http’).createServer(app);
const io = require(‘socket.io’)(http);
app.get(‘/’, (req, res) => {
res.sendFile(__dirname + ‘/public/index.html’);
});
io.on(‘connection’, (socket) => {
console.log(‘a user connected’);
// Handle chat messages
socket.on(‘chat message’, (message) => {
console.log(message: ${message});
io.emit(‘chat message’, message);
});
// Handle disconnections
socket.on(‘disconnect’, () => {
console.log(‘user disconnected’);
const username = socketMap.get(socket.id);
if (username) {
io.emit(‘chat message’, {
sender: ‘System’,
time: new Date().toLocaleTimeString(),
text: ${username} has left the chat,
});
socketMap.delete(socket.id);
}
});
// Add the user’s username to the socket map
socket.on(‘set username’, (username) => {
console.log(user ${username} connected);
socketMap.set(socket.id, username);
io.emit(‘chat message’, {
sender: ‘System’,
time: new Date().toLocaleTimeString(),
text: ${username} has joined the chat,
});
});
