nodejs and javascript communication

Question

I'm building a chat-system in javascript with nodejs as server-side language. So far I've used Socket.io as I though it would be able to handle a large number of clients (aiming at 100k+) but today, 1 week before we are releasing beta I learned that Socket.io have major problems with scalability and so I've decided to change my approach. I need quick, live data transfers between server and client and now I don't know where to look. Maybe simply WebSockets and try to develope these?

Answer 1

I would definitely use ws, it is the fastest library atm.

We are already using it in our project, weezeel, and it is insanely fast plus it supports thousands of concurrent connections.
