Share data between Angular reducers

I have a situation in my app where I need to share data between reducers.

State:
{
   ...
   itemDetails,
   settings
}

In the itemDetails store, I need to update some data and to be able to do this I need some data from the settings store.

(I’m also using facades.)

Is there a possibility to share data between reducers like redux-thunk in react or something like this?

I also have other two options to do this:

  1. Send that settings data to the facade method as a function parameter.
  2. Inject settingsFacades in itemDetailsFacades and send those data directly in the action.

But I’m curious if is there a more elegant method to share data between reducers.

Normally you can just access your store to get the data. For example in an effect it would look like this

constructor(private store$: Store<AppState>) {}

@Effect() specialEffect$ = this.actions$
    .ofType(SOME_ACTION)
    .withLatestFrom(this.store$)
    .map(([action: Action, storeState: AppState]) => {
      // Do something ... use selectors, dispatch action etc.
    });
