I'm reaching you here about ngrx effects, what i am tryign to do is to have a function login that distpatch an action type login and an effect on this action will user my service to make api call. After this return token, i want to dispatch two other action one of type getUserMenu and one of type getUserInfo. Those two action will be of different type and have different effect.
I have 3 stores at the end: one for token and auth one for user info one for menu info
i tried things like that :
login = createEffect(
() =>
this.actions$
.pipe(
ofType(authLogin),
tap(action => {
console.log("EFFECT LOGINNNN");
return this.authService.postLogin(action.username,
action.password).pipe(
map((data: any) => {
console.log("AUTHTHHTHTH DATATA ", data);
let props = data.token;
let payload = {
token: data.token,
isAuthenticated: true
}
this.store.dispatch(moMenuHttpGetListAction({US_ID: action.username}));
this.store.dispatch(userHttpGetInfoAction({US_ID:action.username}));
this.localStorageService.setItem(AUTH_KEY, payload);
}))
})
),
{ dispatch: true }
);
if i set dispatch false login work but no method called for getting user info and user menu but when i set dispatch true i have infinit loop on this same effect the action moMenuHttpGetListAction would look like that :
moMenuHttpGetListEffect = createEffect(
() => this.actions$.pipe(
ofType(moMenuHttpGetListAction),
switchMap(action => {
console.log("MOMENU LOGINNNN");
return this.moMenuService.getKmApplications(action.US_ID).pipe(
map((data: any) => {
console.log("MOMENU DATATA ", data);
console.log("MOMENU DATATA ", action.US_ID);
let payload = {
MO_MENU: data
}
this.store.dispatch(moMenuSetListAction({payload: data}));
this.localStorageService.setItem(MENU_KEY, payload);
}))
})
),
{ dispatch: false }
);
but on this one when i set dispatch to true , i got error compiling. and my action looks like :
import { createAction } from "@ngrx/store";
import { props } from "@ngrx/store";
import { MoMenu, MoMenuState } from "./mo_menu.models";
//TODO CHANGER ME_ID en US_ID
export const moMenuGetErrorAction = createAction("[User] Get Info");
export const moMenuGetIsLoadingAction = createAction("[User] Get Info");
export const moMenuSetErrorAction = createAction('[MoMenu] HTTP GET ACTION',
props<{error: string}>()
);
export const moMenuSetLoadingAction = createAction('[MoMenu] HTTP GET ACTION',
props<{loading: boolean}>()
);
export const moMenuHttpGetListAction = createAction('[MoMenu] HTTP GETLIST ACTION',
props<{US_ID: string}>()
);
export const moMenuHttpGetListErrorAction = createAction('[MoMenu] HTTP GET ACTION Error',
props<{error: any}>()
);
export const moMenuGetListAction = createAction("[MoMenu] Get List");
export const moMenuSetListAction = createAction("[MoMenu] Set Mo Menu List",
props<{payload: MoMenu[]}>());
export const moMenuDeleteAction = createAction("[MoMenu] Delete List");
those are the two reducers concerned as someone ask me to add :
Ngrx is kinda new to me so i'd love some help on this =)
import { AuthState } from './auth.models';
import { authLogin,
authLogout ,
authGetErrorAction,
authGetIsLoadingAction,
authSetErrorAction,
authSetIsLoadingAction
} from './auth.actions';
import { createReducer, on, Action } from '@ngrx/store';
export const initialState: AuthState = {
isAuthenticated: false,
token: undefined,
isLoading: false,
HttpResponse: undefined
};
const reducer = createReducer(
initialState,
on(authSetErrorAction, (state, { error }) => ({
...state, HttpResponse: error
})),
on(authSetIsLoadingAction, (state, { isLoading }) => ({
...state, isLoading: isLoading
})),
on(authLogin, state => ({ ...state, isAuthenticated: true })),
on(authLogout, state => ({ ...state, isAuthenticated: false }))
);
export function authReducer(
state: AuthState | undefined,
action: Action
): AuthState {
return reducer(state, action);
}
import { MoMenuState } from "./mo_menu.models";
import {
moMenuGetListAction,
moMenuDeleteAction,
moMenuHttpGetListAction,
moMenuSetListAction,
moMenuHttpGetListErrorAction,
moMenuGetErrorAction,
moMenuGetIsLoadingAction,
moMenuSetErrorAction,
moMenuSetLoadingAction
} from "./mo_menu.actions";
import { createReducer, on, Action } from "@ngrx/store";
export const initialState: MoMenuState = {
isLoading: false,
HttpResponse: undefined,
MoMenuItems: null
}
const reducer = createReducer(
initialState,
on(moMenuSetErrorAction, (state, { error }) => ({
...state, HttpResponse: error
})),
on(moMenuSetLoadingAction, (state, { loading }) => ({
...state, isLoading: loading
})),
on(moMenuHttpGetListErrorAction, (state, { error }) => (
undefined)),
on(moMenuSetListAction, (state, { payload }) => ({
...state, MoMenus: payload
})),
on(moMenuHttpGetListAction, (state, { US_ID }) => ({
...state
})),
on(moMenuGetListAction, state => state),
on(moMenuDeleteAction, state => state)
);
export function moMenuReducer(
state: MoMenuState | undefined,
action: Action
): MoMenuState {
return reducer(state, action);
}
If some of you guys have any idea for me ?
This is how I'm dispatching multiple actions as a result of another action in NgRx 8:
@Injectable()
export class MyEffects {
myAction$ = createEffect(() =>
this.actions$.pipe(
ofType(myActions.firstAction),
switchMap(action => this.someService.getById(action.someId)),
switchMap((sth: Something) => [
myActions.firstActionSuccess({ payload: sth }),
myActions.secondAction({ payload: sth.xyz }),
// ... more actions
])
)
);
constructor(
private someService: SomeService,
private actions$: Actions
) { }
}
Actions look like this:
export const firstAction = createAction('First Action', props<{ someId: number }>());
export const firstActionSuccess = createAction('First Action Success', props<{ payload: Something }>());
export const secondAction = createAction('Second Action', props<{ payload: string }>());
Hope that helps!
