Looking for help/guidance on multiplayer framework for browser game.

Hello Everyone,

I just joined. I found this site through a youtuber I recently started following. Shout out to Will Kwan, if you're reading this.

Anyway, to the point of this post:

I started writing a very simple card game, in javascript, that is meant to be run in a browser window. I have most of the functionality done from a game logic stance. Since the game is only meant to function as a multiplayer game, I have very limited knowledge on how to proceed.

I am looking for help/guidance on what software/framework/code I need to implement something to handle user sessions. And, how I incorporate that into my current code base.

I've come across a few open source things on github but also read that node.js may be the answer. Where do I begin? Can someone give me a push into the right direction?

Appreciate the time you've taken to read this post and reply.

Thanks,
