所以我對此有點不以為然。希望你能給我道歉。我正在嘗試將多個 Angular 元素（Web 組件）插入到 Prestashop 模塊，即 PHP。由于沒有一個包含許多模塊的 Angular 應用程序，我無法使用商店將數據從一個元素發送到另一個元素。我想過創建一個負責創建 NGRX 商店的庫，并將其保存到 window.store（例如），因此同一個商店可以被多個獨立的角度應用程序使用。這里的問題是我必須在許多 Angular 元素中調用庫，所以我在構造函數中注入了不同的存儲。我對嗎？例如：import {  ActionReducer,  ActionReducerFactory,  ActionReducerMap,  ActionReducerMap,  ActionsSubject,  ReducerManager,  ReducerManagerDispatcher,  StateObservable,  Store,} from '@ngrx/store'import { Observable } from 'rxjs';const storeName = 'store'@Injectable({  providedIn: 'root'})export class StoreSyncService {  store: any = null  // option 1 constructor:  // are we, when including the library in others angular apps, instantiating store over and over?  constructor(private store: Store) {     if (window[storeName]) {      this.store = window[storeName]    } else{      window[storeName] = this.store    }  }  // option 2 constructor (please apologise me as I don't know how injection works very well).  // Any link to clarify this is welcome  constructor() {    if (window[storeName]) {      this.store = window[storeName]    } else{      const stateObservable$: StateObservable = new Observable()      const actionsObserver: ActionsSubject = new ActionsSubject()      const dispatcher: ReducerManagerDispatcher = new ActionsSubject()      const initialState = {}      const reducers: ActionReducerMap<any, any> = {}      const reducerFactory: ActionReducerFactory<any, any> =  whatever      const reducerManager: ReducerManager = new ReducerManager(dispatcher, initialState, reducers, reducerFactory)      this.store = new Store(stateObservable$, actionsObserver, reducerManager)      window[storeName] = this.store    }所以回顧一下，如果我想在多個獨立的角度應用程序之間共享狀態，你會怎么做？我嘗試使用 localStorage，添加事件以將 NGRX 狀態與本地存儲中的數據同步，反之亦然，但有時會出現無限循環，有時會出現數據不同步的邊緣情況。感謝您的幫助和理解
