What framework to use to create a server for a multiplayer game?

Question

Game development

There is an idea to make a mobile game (poker) with multiplayer support.
There was a question about development of the server. I don't want to create another bike running on UDP rails with punctured deadlock tires and a bunch of safety issues. Well, you understand me =)

Ideally, I would like to have a server in which it is already implemented: game rooms, chat support, in general it is ideal if there is already game logic.
I'm almost sure that there is no complete solution, so I'll be glad to see frameworks for less painful server writing (like, for example, RedDwarf ).

Priority languages ​​and technologies: c#, java, javascript(node.js).

Thank you for your attention!

Answer 1

Here's an example, although it's more of a ready-made server with the ability to write extensions than just a framework:
