Call ngAfterViewInit of Angular component from common place

I am using bootstrap tooltip.
I want to trigger ngAfterViewInit for every component from some common place.

Common place(like app.module.ts)

ngAfterViewInit() {

    $('[data-toggle="tooltip"]').tooltip();

  }

Component_1:
There is no ngAfterViewInit in component, still life cycle is trigger from some common place.

Component_2:
This component has ngAfterViewInit,

ngAfterViewInit() {

    // Some extra functionality

  }

In this case ngAfterViewInit is triggered from both the places(common place as well as from it's respective component)

Is there any way to achieve this?

Thanks

AfterViewInit is an interface, just extends from a component class and use wherever you want to use

A lifecycle hook that is called after Angular has fully initialized a component's view. Define a ngAfterViewInit() method to handle any additional initialization tasks. so each component has there owned responsibility

There isn't "one common place" where you can define a global behavior for all of your components.

Instead, you can create the following class and make your desired components extend it:

export abstract class BaseComponent implements AfterViewInit {

  /**

   * View initialization behavior. Note that derived classes must not implement AfterViewInit .

   * Use viewInit() on derived classes instead.

   */

  ngAfterViewInit(): void {

    // Your code

    this.viewInit();

  }



  /**

   * Function that allows derived components to define an additional view initialization behavior

   */

  abstract viewInit(): void;

}

I think you misunderstood the question, I want some common place from where I can all the ngAfterViewInit. Not only from component. I want extra hook or listener.
