When approaching the issue from a different angle, one possible solution involves utilizing Angular Animations' void state along with *ngIf.
To start, import the BrowserAnimationsModule into your app.module.ts:
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
@NgModule({
imports: [ BrowserAnimationsModule ]
})
In the parent component that contains the component you wish to remove, you can apply the void state animation by using *ngIf. For example:
@Component({
animations: [
trigger('animateDestroy', [
state('void', style({ opacity: '0' })),
transition('* => void', animate('500ms ease'))
])
],
template: `
<component-to-destroy *ngIf="someBoolean" @animateDestroy>
</component-to-destroy>
`
})
export class ParentComponent {
someBoolean = true;
}
By changing the value of someBoolean to false, Angular will remove the component from the DOM due to the presence of *ngIf. Prior to removal, the animateDestroy trigger with * => void instructs Angular to animate the element out before eliminating it from the DOM.
For more information on Angular Animations and the void state, refer to the official documentation.
This approach may not rely on CSS directly, but it offers similar outcomes. It allows the template to control the "destroyed or not" state of the component using a boolean instead of requiring complex logic within the class.
I hope this explanation proves helpful in navigating this scenario.
