How can I implement a pub/sub pattern in my application?

To implement a pub/sub pattern, you can use libraries like Redis or MQTT. Do you have a specific technology stack in mind?

I'm using Node.js for my backend. Any recommendations?

For Node.js, you can use libraries like 'EventEmitter' for simple pub/sub or 'Socket.IO' for real-time communication. Would you like code examples?

Yes, please provide a code example using Socket.IO.

Here's a basic example:

const io = require('socket.io')(3000);

io.on('connection', (socket) => {
    socket.on('message', (data) => {
        socket.broadcast.emit('message', data);
    });
});

This sets up a server that broadcasts messages to all connected clients.
