How to make chat on websocket?

Question

JavaScript

Good evening Toaster.
I want to start learning WebSocket (JS) by writing a little chat.
What do I need for this?
I'm specifically interested in links (repositories / articles / guides) and the necessary algorithm and a set of technologies.
Do I need a node.js server for all this?

Answer 1

I think that here you can learn a lot of useful things https://learn.javascript.ru/nodejs-screencast
In the second part, a chat on sockets is just being created.
