How do I implement WebSockets in my web application?

To implement WebSockets, you'll need to set up a WebSocket server and connect it to your client. Do you have a specific framework in mind?

I'm using Node.js for the server. What libraries should I use?

For Node.js, you can use the 'ws' library, which is simple and efficient. Would you like a code example?

Yes, please provide a basic example of a WebSocket server using 'ws'.

Here's a simple example:

const WebSocket = require('ws');
const server = new WebSocket.Server({ port: 8080 });

server.on('connection', (socket) => {
    socket.on('message', (message) => {
        console.log('received: %s', message);
    });
    socket.send('Hello! Message from server.');
});

This sets up a WebSocket server on port 8080.
