A lifecycle hook that is called when a directive, pipe, or service is destroyed. Use for any custom cleanup that needs to occur when the instance is destroyed.

Lifecycle hooks guide

API

    
      interface OnDestroy {  ngOnDestroy(): void;}

ngOnDestroy

void

A callback method that performs custom clean-up, invoked immediately before a directive, pipe, or service instance is destroyed.

@returnsvoid

Usage Notes

The following snippet shows how a component can implement this interface to define its own custom clean-up method.

@Component({
        selector: 'my-cmp',
        template: `...`,
      })
      class MyComponent implements OnDestroy {
        ngOnDestroy() {
          // ...
        }
      }
