Udemy – Socket.IO (with websockets) – the details. (socket io v2)

Websockets are one of the coolest things to hit the web in ages. They allow the browser real-time communication bridging one of the last gaps in both human and web-based communication.

Socket io is the king library that uses websockets under the hood.

There’s a good chance if you’re reading this, you’ve heard about socket io.

Maybe even done a tutorial on it. But how far did you get? In my experience, the vast majority of the material on the web goes no farther than a quick-start, instant chat app.

You don’t learn how anything works, never look at the docs, and are stuck at the end wondering what to do now. The remaining shred of material is waaaaay over everyone’s head.

The fact that the websocket API was standardized in 2011 and most developers still don’t know how to use it is evidence of the gap.
