如何使用 NgRx select 作为 Subject 而不是 BehaviorSubject

Question

有没有办法将 NgRx select 视为 Subject 而不是 BehaviorSubject？

我不想在第一次订阅时执行下一步（默认行为）。相反，想在状态改变时执行它。

this.store.pipe(select(fromAuth.selectErrorMessage)).subscribe((message) => {
      /* This content is executed the first time the subscription is made, 
         and after that is executed everytime the state change */
      this.isLoading = false;     
      this.errorMessage = { ...message };
});

Answer 1

this.store.pipe(select(fromAuth.selectErrorMessage)).pipe(skip(1))

将忽略当前值，只发出下一个值。
