NativeScript - Migrating Project Structure

Question

I want to migrate an Angular app to a {N} code-sharing structure. I used this article to get started. Would you help me solve the below issue? It seems like a mis-configuration.

When I execute:

ng add @nativescript/schematics

I get the following error:

success Saved 1 new dependency.
info Direct dependencies
└─ @nativescript/schematics@0.5.0
info All dependencies
└─ @nativescript/schematics@0.5.0
✨  Done in 3.25s.
Installed packages for tooling via yarn.
Two or more projects are using identical roots. Unable to determine project using current working directory. Using default workspace project instead.

My @angular packages are 7.1.1

I use yarn as a package manager.

This is my angular.json:

Any help is highly appreciated!

Answer 1

Need to follow the following steps

1. Create a new angular app using - ng new my-app
2. Navigate to my-app folder
3. Execute command - ng add @nativescript/schematics
4. Finally execute tns run android --bundle - this will generate an auto generated page in emulator.

I see some differences in the project settings.
