      interface OnDestroy {}

ngOnDestroy

void

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

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: `...`,        standalone: false,      })      class MyComponent implements OnDestroy {        ngOnDestroy() {          // ...        }      }
