I would like to reuse an angular 1 module in a NativeScript - angular 2 app.
I have read about the upgrade module and its
[...] service that can bootstrap and manage hybrid applications that support both Angular 2 and Angular 1 code.
No support for Angular 1 module is planned as stated in this comment from nativescript-angular contributor.
We never intended to support Angular 1 components, and I doubt we'll allocate resources for it in the foreseeable future.
That said, there is no problem for support for the UpgradeAdapter come from a separate library developed by the community. We'll consider PR's that make it easy for such a library to do its job.
