Currently there is a plethora of websocket libraries for node.js, the most popular seem to be:
- https://github.com/Worlize/WebSocket-Node
- https://github.com/einaros/ws
- https://github.com/LearnBoost/engine.io
- https://github.com/learnboost/socket.io
- https://github.com/sockjs
However I can’t find any solid concrete comparisons between any of them…
Apparently Socket.io was awesome, but has become quite dated and has failing builds. Both ws and websocket-node claim they are the fastest. And engine.io seems new, but a lot heavier than the lighter aletarntives.
It would be amazing if we or someone could put together an answer that serves as a guide on which socket library to use and when, as well as a comparison between them.
