Description

I'm getting warning that there is collision detected. Each time I will make change in the component then after saving changes the warning will occur for that specific component. Each one of these components has a selector. Here is an example:

@Component({ selector: 'app-home', standalone: true, imports: [ CommonModule, ProjectCardComponent, PostItemComponent, RouterLink ], template: '...' })

Warning will not show up on initial load tho.

Please provide the exception or error you saw

NG0912: Component ID generation collision detected. Components 'HomeComponent' and 'HomeComponent' with selector 'app-home' generated the same component ID. To fix this, you can change the selector of one of those components or add an extra host attribute to force a different ID. Find more at https://angular.io/errors/NG0912
