What resources are there with documentation on setting up the socket.io library?

Question

Node.js

Hello, maybe the question is stupid, but I can’t find the socket.io library settings for node js in more detail, I need to transfer data from the server to the client and back as quickly as possible and found out that socket.io has some settings and I would like somewhere read about them in more detail, but I didn’t find any information anywhere (at least on the off site there was nothing said about the settings). Maybe someone knows where there is such information, or write here ...
Thank you in advance for your answer

It is necessary to study the source code and underlying technologies (TCP/IP), and specify the problems, explaining the problem is half the solution, as they say.
