Get params from typeOf ngrx effects

I have something like this

ngOnInit() {
  this.store.dispatch(new TutorialActions.GetTutorials(1, 20));
}

export class GetTutorials implements Action {
  readonly type = GET_TUTORIALS
  constructor(public number: number, public offset: number) {}
}

And then i have effects like this

export class TutorialEffects {
  loadTutorials$ = createEffect(() =>
    this.action$.pipe(
      ofType(TutorialActions.GET_TUTORIALS),
      switchMap(() =>
        this.tutorialService.getAll(0, 20).pipe(
          map((tutorial: Tutorial[]) => new TutorialActions.SuccesGetTutorials(tutorial)),
          catchError((error) => of (error))
        )
      )
    )
  );
}

The problem is in ofType(TutorialActions.GET_TUTORIALS), this.tutorialService.getAll(0,20).

That value should be passed from ngOnInit functions and can be dynamic?

Yes, you have access to the action object. So you can access the properties of it.

export class TutorialEffects {
   loadTutorials$ = createEffect(() =>
     this.action$.pipe(
       ofType(TutorialActions.GET_TUTORIALS),
       switchMap((action: any) =>
         this.tutorialService.getAll(action.number, action.offset).pipe(
           map((tutorial: Tutorial[]) => new TutorialActions.SuccesGetTutorials(tutorial)),
           catchError((error) => of (error))
         )
       )
     )
   );
 }
