Can you give me a specific example of a chat application using Socket.IO?

Sure! A simple chat application can be built where users can join rooms and send messages in real-time. Each message is emitted to all users in the room.

How do I set up a basic Socket.IO server?

To set up a basic Socket.IO server, you need to install the Socket.IO library, create an HTTP server, and then attach Socket.IO to it. Would you like a code snippet?

Yes, please provide a code snippet!

Here's a basic example:

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);

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

server.listen(3000, () => {
    console.log('Server is running on port 3000');
});

This sets up a basic server that listens for connections.
