What are the options for developing a game server?

Question

JavaScript

Recently, I decided for myself to gain experience in JavaScript and found out that, in principle, my whole idea can be implemented using this PL. What exactly I would like to do:
1. Develop a game server on Node.JS that would be able to give JSON (well, or something else) representations of the current state of the player (s) and, in principle, everything (the main calculations will be on the client). Why: a small RPG for 5 players with the same small world (of course, as you delve into the subject, there will be improvements and improvements).
2. Develop a data structure for MongoDB that would store the player's state in itself.
3. Develop a client for the game (well, there will be: rendering on canvas, handling collisions, requests to the server, etc.)
I really ask you for advice on organizing a server (what to read about programming like this?), Well, it’s desirable for the rest of the points. Thanks in advance!
PS I am afraid of the monstrous Talmuds, but if there is not a small amount of information available, I am ready to overcome my fears).
PPS Perhaps there will be several games (ping-pong for four, for example) what to do in this case?
