Allow Mapbox to load local json map style definition

[lbaey]

Hi
I needed to load a different than "native mapbox style" in my map.
I added the ability to load a json map style file definition with a new special url pointing at the "assets" nativescript directory.
The Url is assets:// and points to the /app/assets/ directory of your project.
Usage example :

onMapReady(args) {
                console.log("Switching Style");
                args.map.setMapStyle("assets://RM-raster-style.json");
}

Tell me what you think and if you think this is a good approach.
Cheers

Hi! I think that's a great approach, but perhaps it's worthwhile to explore the possibility of using ~/yourfile.json instead because that's the standard NativeScript approach to reference files in the /app folder (~ being and alias for app). Do you think that would be possible? That way users aren't forced to create an assets folder to store the file in.

Can you perhaps also add a sample json file to the demo in the repo? I'd love to play with it!

OK, I was not sure on how to refer to local path, but the nativescript "~" seems ideal.
I've switched to this URL scheme tracking to let mapbox load the json file.
I've also added some doc and (untested and commented) example so you can play ;)

Awesome! I'll be testing this soon.

Works like a charm! I only tested with ~/ though. THANKS!
