How can you ensure that a particular component is checked only once by Angular's change detection mechanism?

  • Using the ChangeDetectionStrategy.OnPush strategy.
  • Wrapping the component in an async pipe.
  • Manually triggering change detection for that component.
  • Adding the component to the AppModule declarations array.
You can ensure that a particular component is checked only once by Angular's change detection mechanism by using the ChangeDetectionStrategy.OnPush strategy. This strategy tells Angular to only run change detection on a component when its input properties change or when you manually trigger it. The other options do not provide a way to control change detection behavior in the same way.
