React Native and Socket.io

React Native finally supports Websockets. Which is awesome, however there is one gotcha with socket.io.

1. npm install socket.io-client. This will just pull down the socket.io javascript client

2. 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 react-native first!

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.
