How propagate action.payload from Action in ngrx-effect to catchError or map operator?


I write ngrx effect with httpRequest which use action.payload of Action.

From request I get data which I use in map operator (if error occur i handle it in catchError)

From Backend I get only boolean value, How I can propagate action.payload from Action to map or catchError operator?

Example:

effect= this.actions$
    .ofType(Actions.IS_OK)
    .pipe(
         mergeMap(action => this.service.isOk(action.payload),
         map((isOk: boolean)  => new SuccessAction(isOk, action.payload), //here I need somehow get to action.payload value
         catchError(error => of(new ErrorAction(error, action.payload))) //here I need somehow get to action.payload value
     );

And I can not store payload to store, because I have triggered more actions: Actions.IS_OK

Thanks for help


Solution

  • Can you try :

    effect = this.actions$
        .ofType(Actions.IS_OK)
        .pipe(
             mergeMap(action => this.service.isOk(action.payload).pipe(
                 map((isOk: boolean) => { payload: action.payload, isOk: isOk} )
             ),
             // need to create proper interface forPayload + isOk 
             map((payloadPlusIsOk: any)  => new SuccessAction(payloadPlusIsOk.isOk, payloadPlusIsOk.payload),
             catchError(error => of(new ErrorAction(error, action.payload))) //here I need somehow get to action.payload value
         );
