Usage with Expo

** Please ensure:

• I’m using the latest version of react-native-debugger
• I have read README.md

** Please provide the following information if you found some bugs or have question:

React Native version: Expo SDK 17 Platform: Android Is real device of platform: No Operating System: Arch Linux

I’m trying to get react-native-debugger to work with Expo and my genymotion android device, without success so far. When running the debugger, it will always listen on a random port, and I cannot figure out a way to tell expo and react-native-debugger to agree on the port.

• Updating my package.json file with the following script didn’t help:

     "scripts": {
      "postinstall": "rndebugger-open --expo"
    }
  

• Since Expo starts the RN packager for me, I don’t understand how to run REACT_DEBUGGER="unset ELECTRON_RUN_AS_NODE && open -g 'rndebugger://set-debugger-loc?port=19001' ||" npm start
• I tried xdg-open "rndebugger://set-debugger-loc?host=localhost&port=19001"xdg-mime query default http without success (not sure how to assign react-native-debugger to this specific mime.

for anyone that would like a bash function to open the debugger on the port of your choosing

function rndebug() {
  if [ -n "$1" ]
  then
    open "rndebugger://set-debugger-loc?host=localhost&port="$1""
  else
    open "rndebugger://set-debugger-loc?host=localhost&port=19001"
  fi
}

I managed to connect to react-native-debugger, yay!

Basically:

• Start react-native-debugger app
• Close browser debugger-ui if opened
• restart expo project and open on android
• manually run npm run postinstall in the terminal
• set remote js debugging

Seeing a lot of errors in the console though, stuff like

Uncaught TypeError: Cannot read property 'getHostNode' of null
    at Object.getHostNode`

Also, I cannot open the <App> component (which is kind of what I care about):

Any idea regarding these last issues ?
