Fable on React Native demo

This is a demo application for React Native development in F# using Fable.

If you want to try it out then please do the following:

Make sure FSharp is installed

Make sure that the FSharp compiler is properly installed on your operating system:

Make sure React Native works

Install the Ionide VS Code extenstion for F#
Install the VS Code extension for React Native
Go to https://facebook.github.io/react-native/ and do all steps of the getting started tutorial
At this point you should have the default Javascript React Native "Hello World" running

Running F# code on React Native

Pull latest master
Run "npm install" from command prompt
Open Android Simulator
Open VS Code
Press F5 to start debug
Go to android device simulator and you should see something like

Go to VS Code and hit Ctrl+Shift+B this will activate fable watch
Go to the F# source in VS Code make a change and save the file
Fable watch should pick up this change automatically and compile it
Go to android device simulator and press r+r - change should be visible

This could look like:

Error handling

Unauthorized device

If you hit F5 in VS Code and it compiles everything, but nothing happens... go to the debugger output (Ctrl+Shif+y) and search for hints. One pitfall might be "Skipping device, Device is UNAUTHORIZED". With

adb devices

you can see the list of devices, probably one of them is marked as UNAUTHORIZED. First, try

adb kill-server

and try it again. If it doesn't help, you can push the public key onto the device again:

cd ~/.android && adb push adbkey.pub /data/misc/adb/adb_keys
