import {Inject, Injectable} from '@angular/core';

@Injectable()
export class exampleService {
    constructor(@Inject(AppStore) private store: Redux.Store<AppState>) {}
    getExampleState(){
      console.log(this.store.getState().example);
   }
}

изменить состояние

import * as Redux from 'redux';
import {Inject, Injectable} from '@angular/core';

@Injectable()
export class exampleService {
    constructor(@Inject(AppStore) private store: Redux.Store<AppState>) {}
    setExampleState(){
       this.store.dispatch(updateExample("new value"));
   }
}

export interface UpdateExapleAction extends Action {
  example?: string;
}

export const updateExample: ActionCreator<UpdateExapleAction> =
   (newVal) => ({
     type: EXAMPLE_CHANGED,
     example: newVal
