How to choose a specific reducer to dispatch in ngrx store?

Question

Angular

Hello. I didn’t quite understand how to dispatch to a specific reducer.
There is

export const rootReducer = {
    user: userReduser,
    dialogs: dialogsReduser
};

Which I include in app.modul.
in the dispatch service like this

private store: Store<MainState>
this.store.dispatch(new Actions.ToggleSignInDealog(true))

If you do this, the action goes through all the reducers. Tell me how to choose a certain one?
There is a suspicion that it can be somehow selected by the select type

Answer 1

The action must pass through all reducers.
