在 Node.js 中使用哪个 websocket 库？ [打烊]

Question

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.

Answer 1

Update: This answer is outdated as newer versions of libraries mentioned are released since then.

Socket.IO v0.9 is outdated and a bit buggy, and Engine.IO is the interim successor. Socket.IO v1.0 (which will be released soon) will use Engine.IO and be much better than v0.9. I'd recommend you to use Engine.IO until Socket.IO v1.0 is released.

"ws" does not support fallback, so if the client browser does not support websockets, it won't work, unlike Socket.IO and Engine.IO which uses long-polling etc if websockets are not available. However, "ws" seems like the fastest library at the moment.

See my article comparing Socket.IO, Engine.IO and Primus: https://medium.com/p/b63bfca0539
