exhaustMap(action =>
components.deleteComponent(action.payload.id).pipe(
map(() => deleteComponentAction.success()),
catchError((error: Error) => of(deleteComponentAction.failure(errorHandler(error)))),

没有强迫你需要一对一的输入/输出比率。如果需要,可以使用mergeMap(也称为flatMap)发出多个动作。 你可以做以下事情-
components.deleteComponent(action.payload.id).pipe(
合并映射(()=>of(deleteComponentAction.success(),fetchCategoryComponentList()),
catchError((error:error)=>of(deleteComponentAction.failure(errorHandler(error)),
),
