ngrx 8 effects dispatch action of other type

Question

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!

You can do like this to dispatch multiple action in your effect

@Effect()
    someEffect$: Observable<Action> = this.actions$.pipe(
        ofType<SOME_ACTION>(SOME_ACTION),
        switchMap(_ =>
            of(
                new myAction.Refresh(),
                new myAction.Clear()
                // another action
            )
        )
    );

Also make sure to have approriate effect that listen on your action to make it work
