Socket.IO server + Socket.IO-client

Im actually desperate now. I need to design and code solution I've never even thought I'd be making, and it seems completely unrealistic to achieve (for me) with clean express. But I might be wrong.

What I need is:

• REST API - done
• Socket.IO server - done
• bunch of Socket.IO-client connections - can be done

But now, what I need is to some efficient way of making it, to communicate with each other. So the app has to be basically a bridge between all of them. I was thinking of using some kind of state managing library, like Redux solution, that way I (at least I think) could achieve it pretty easy. But I also haven't found any of this kind, for the node, or neither found how to achieve it on the backend.

So the question is: what's the best solution, to achieve one-to-many and many-to-one communication between multiple socket.io connections? Again, to make it clear.

socket-client connection = connecting to already existing server, as a node app.

I am not speaking of making simple solution for clients to communicate between each other on 1 server. I want to create 1 server, and to connect to multiple others.
