Role-based security in Firebase
/*
This example shows how you can use your data structure as a basis for
your Firebase security rules to implement role-based security. We store
each user by their Twitter uid, and use the following simplistic approach
for user roles:
0 - GUEST
10 - USER
20 - MODERATOR

Notes on auto crashlytics and cordova integration

After adding crashlytics code (crashlytics.sh) & Patching the xcodeproject file (crashlytics.rb)

  • It will work in xcode but not in cordova anymore.

  • This is because xcoder writes the .xcodeproj file in a format that node-xcode doesn't understand.

  • you need to 'beautify/sanitize' the file again.

    • brew install xcproj
    • and run xcproj -P <path to your xcodeproj file> touch

  • now you are ready to go in cordova
