Instead of IP address, use API keys for user-specific limits:

Create a file named server.js in your project directory and add the following:

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

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

app.use(express.static('public'));

io.on('connection', (socket) => {
    console.log('A user connected');

    socket.on('chatMessage', (msg) => {
        io.emit('chatMessage', msg);
    });

    socket.on('disconnect', () => {
        console.log('User disconnected');
    });
});

const PORT = process.env.PORT || 3000;
server.listen(PORT, () => console.log(`Server running on port ${PORT}`));
