React Native finally supports Websockets. Which is awesome, however there is one gotcha with socket.io.
Everything works great but there is one issue that
window.navigator.userAgent doesn't exist. Socket.IO checks to deal with some browser incosistencies but we don't care. So all we have to do is create it. However make sure you require
Just like so
window.navigator.userAgent = "react-native"; var io = require("socket.io-client/socket.io");
Now you can do as you please with your new glorious websockets.
