Multiplayer browser game - sources?

Question

Canvas

We want to launch a multiplayer game like agario / slitherio. Maybe someone wrote something like this - there are sources, developments that you can use or with whom to consult, how to quickly create and on what technologies - they offer different options, but everyone has the main problem of ping / fps - maybe someone has already solved such issues?

Answer 1

I tried to write, there is a working prototype, it works in conjunction with node. js.
The topic of multiplayer of this nature is very complex. Even with a small ping, there were twitches, for a long time I could not understand why, until I read an article somewhere about this "glitch" (there is something like that the server should sort of live in the future and calculate everything in advance, etc.)
I advise you to start with the most detailed theory of multiplayer problems in terms of client-server interaction, there are a lot of nuances and techniques, there are plenty of articles on the internet. This knowledge will help to bypass (partially) fps problems.
ps I can give my sources, write in a personal.
