How to get the state from the ngrx store without reselect library?

How to get the state from the ngrx store without using the reselect createSelector and store.select method in this example?

export const getBookCollection = createSelector(getBookEntities, getCollectionBookIds, (entities, ids) => { return ids.map(id => entities[id]); });

constructor(store: Store<fromRoot.State>) { this.books$ = store.select(fromRoot.getBookCollection); }

Using only the store.select you could do:

export const getBooksCollection = (state: State) => {
    const ids = state.collection.ids;
    const entities = state.books.entities;
    return ids.map(id => entities[id]);
}

constructor(store: Store<fromRoot.State>) {
    this.books$ = store.select(fromRoot.getBookCollection);
}
