问题 I have to sets of Json got from the form the state data objetSet1: {id: 12, name: 'Foo Bar', email: 'foo@bar.com'}, {id: 23, name: 'Bar Foo', email: 'bar@foo.com'}, {id: 61, name: 'Barbell', email: 'barbell@mail.com'}, {id: 45, name: 'Joe Ocean', email: 'joe@ocean.com'} objectSet2: {ObjectId:15, name: 'someone', email: 'someone@mail.com'}, {ObjectId: 23, name: 'sometwo', email: 'sometwo@mail.com'}, {ObjectId: 72, name: 'seven ', email: 'seven@mail.com'}, {ObjectId: 23, name: 'five ', email:

问题 I am using a polling scheme in my Angular application using NgRx. To simplify things, I have something like the following... public stopPolling$ = createEffect(() => this.actions$.pipe( ofType(actions.stopPolling), tap(_ => this.isPollingActive = false), map(_ => actions.stopPolling()) ), { dispatch: false }); public continuePolling$ = createEffect(() => this.actions$.pipe( ofType(actions.getData), tap(_ => this.logger.debug('continue polling')), delay(8000), switchMap(_ => this.pollData()) )

问题 I've worked on a few Angular apps that implemented Redux (NgRx). I can't figure out my current project's issue. Actions: export class GetUserFromStorage implements Action { readonly type = UserActionTypes.GetUserFromStorage; } export class GetUserFromStorageSuccess implements Action { readonly type = UserActionTypes.GetUserFromStorageSuccess; constructor(public payload: User | null) { } } export class GetUserFromStorageFail implements Action { readonly type = UserActionTypes

问题 I made multiple requests in parallel. then I throw error when timeout. getAllDirections() { ... return from(urls).pipe( // a list of api urls mergeMap((urlParam, index) => this.http.get<ISchedules>(urlParam[0]).pipe( map(dataRes => { return dataRes; }), timeout(6000), catchError(error => { console.log(error); return throwError(`Request timeout ${error}`); }) ) ) ); Then in my effect I capture the error $LoadSchedulingsByDirectionsByBranch = createEffect(() => this.actions$.pipe( ofType<any>

问题 When using copy and paste to add new actions in NgRx, it is sometimes possible to forget to change the action type that is a plain string. Sure, making it a static static var makes it less likely, but still possible. How do you detect this oversight? It can cause weird bugs that are hard to track down at runtime and seems to be something that is easier to avoid at compile time. For example, these will cause an issue at runtime, without any warnings at compile time export const meeting_user

问题 I am having some trouble chaining actions one after the other in an Effect that makes an HTTP-request. Here's the Effect code: export class UserEffects { @Effect() update$: Observable<Action> = this.actions$.ofType(user.USERCHANGE).pipe( switchMap(data => this.authService.login(data['payload'])), map(userInfo => new UserChangedAction(userInfo)), tap(() => this.store.dispatch( new LoginStateChangeAction(localStorage.getItem('token'))) ) ); constructor(private authService: AuthService, private
