In the default React Native app scaffolding you have to edit AppDelegate.m to change where it loads the code if you want to test on your device. I use the following snippet to detect if it's being compiled for Debug or Production and for the Simulator or a device. For Production it uses a copy of the code included in the bundle, for Debug on the simualtor it loads from a server on localhost and for Debug on a device it loads from a server on a given IP address.

NOTE: You need to edit YOUR-IP-HERE and change it to the IP to load the code from when in Debug mode on a device. You could use a service like ngrok to make this work from anywhere.

  NSURL *jsCodeLocation;

  // Loading JavaScript code
  #if DEBUG
    // For Debug build load from development server. Start the server from the repository root:

        serialNumber = get.invoke(c, "gsm.sn1") as String

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).
