What happens if the phone goes to sleep?

[hcientist]

If i have a socket.io connection from an iphone to a (node) server, and then the phone turns off its display, can the app still receive socketio messages? is anything special required to do this?

This isn't a library specific question but is in relation to the platform itself. Read up here on the background and suspended states

No, only apps using voip have this option to run in the background. The best practice is to monitor when the app is going to the background and send an update to the server noting this. Then whenever that user gets a message default to push notifications.
