Is there a library for organizing a real-time game server over web sockets, taking into account delays?

Question

Node.js

Hello. I thought up a toy to write a simple browser. But here the question arose with how to solve the problem of pings. I read the comments here habrahabr.ru/post/182678/#comment_6528360 and realized that everything is not so simple. And there the implementation tips say to read here: https://developer.valvesoftware.com/wiki/Source_Mu... .
But I thought that the problem is not new, for sure there are already ready-made solutions for implementing the game taking into account pings in Node.js (well, or another server language). Do you know any? (I want to write something like tennis, so it's important that the solution somehow solves the problem of delays).
Thanks to all)

There are no new problems in programming. All problems of brakes, rendering, pings, data storage are very old. You either come up with (find) a good solution or you don't. The developers of Node.js didn’t even know that games would be written on their lib. They checked on a couple of databases and that's it. So in everything. The same Microsoft does not write a cruise killer before the release of a new version of DX. These are all the problems of the programmer who decided to use it for other purposes.
