Broadcasting using socket.io in Node.js #20 | Backend with Node.js
In this video, I’ll explain Socket.IO message broadcasting using socket.emit(), socket.broadcast.emit(), and io.emit(). You’ll learn the difference between sending messages to a single client, all clients except the sender, and all connected clients. We’ll build a simple real-time example to clearly understand how data flows between clients using different emit methods. By the end, you’ll have a clear understanding of how broadcasting works in real-time Node.js applications.
