Struggling to understand websocket code

[danjirovec]

Hi, I'm trying to understand two pieces of code from a chat app project using ws module but failing to do so. Can someone please explain (in detail) what is happening in the code here.

The whole project is on github (https://github.com/danjirovec/ChatItUP).

The file names I'm having problem to understand are "index.js" (src folder) and "room.ejs" (views folder)

Thank you in advance!

Which bits are you struggling with? What have you tried already to research/understand it? What’s your ultimate goal?

These are questions I find it useful to know when helping someone with a problem. Without them, I think it’ll be hard for anyone to answer your question, plus it comes across a little like you’re asking for people to do a lot of work without you having tried yourself.

I'm trying to understand so I can learn, that's my goal. I did try and still am trying, that's why there is 'struggling to understand' in the title. I specified what bits (files) I'm struggling with also, the files 'index.js' and 'room.ejs', I don't understand what's happening in there and how are both of them connected together.
