Thanks for your question.
There is an ongoing project for sharing code between Angular 2.0 for NativeScript and the Web:
Currently, the Chart, SideDrawer, ListView and Calendar components from NativeScript UI are available for mobile only.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
