standalone migration's prune-ng-modules mode doesn't update standalone imports #51420
Description
Which @angular/* package(s) are the source of the bug?
core
Is this a regression?
No
Description
Standalone migration's prune-ng-modules doesn't update imports properly when the pruned NgModule is referenced by a standalone component.
The following code:
@Component({
standalone: true,
template: `<app-child/>`,
imports: [ChildModule]
})
class App {
}
@Component({
selector: 'app-child',
standalone: true,
template: `...`,
})
class Child {
}
@NgModule({
imports: [Child],
exports: [Child]
})
class ChildModule {}produces:
@Component({
standalone: true,
template: `<app-child/>`,
imports: []
})
class App {
}
@Component({
selector: 'app-child',
standalone: true,
template: `...`,
})
class Child {
}and breaks the app, while it should produce:
@Component({
standalone: true,
template: `<app-child/>`,
imports: [Child]
})
class App {
}
@Component({
selector: 'app-child',
standalone: true,
template: `...`,
})
class Child {
