Nativescript project cannot run ng serve

Question

If I try to run the following command, this happens:

ng serve
An unhandled exception occurred: No projects support the 'serve' target.
See "/tmp/ng-YKKFYj/angular-errors.log" for further details.

in the same directory, where the angular.json, the package.json, src folder etc. is, see:

The project can be build for Android though.

Answer 1

You should use Schematics for code sharing project which does all the setup for Web and iOS / Android.

If you had created it from template, you might have to manually configure the project to support web.
