问题
If nativescript is using javascript engine behind the scene. If I use angular for nativescript development, shouldn't I be able to use angular-fire2 for firebase.
if I could code sharing would be much better with Web and Mob App.

https://stackoverflow.com/a/46088932/6408287 contains the answer you are looking for. In short - NativeScript does not implement the node.js modules specification.
Angular-fire2 is made to run inside node.js, whereas mobile firebase sdks are made to run on mobile platforms. Efficiently. Hence the difference in APIs.
Even if you were to somehow run angular-fire2 on NativeScript, chances are it wouldn't execute as well as the mobile sdks would.
