How to get access of the state tree in effects? (@ngrx/effects 2.x)

Question

I am updating @ngrx/effects from 1.x to 2.x

In 1.x I have access of state tree in effect:

  constructor(private updates$: StateUpdates

        

Answer 1

Another way is using .withLatestFrom(this.store). So the complete code is:

  constructor(
    private actions$: Actions,
    private store: Store
  ) {}

 @Effect() bar$ = this.actions$
    .ofType(ActionTypes.FOO)
    .withLatestFrom(this.store, (action, state) => state.user.isCool)
    .distinctUntilChanged()
    .filter(x => x)
    .map(() => ({ type: ActionTypes.BAR }));
