Websocket API to replace REST API?

Question

I have an application whose primary function works in real time, through websockets or long polling.

Answer 1

Do I want updates from the server?

• Yes: Socket.io
• No: REST

• Learnin: I don't have unlimited time for my learnin. Things have to get done!

I'll still use Socket.io in my project, but not for basic web forms that REST will do nicely.
