和。他们都给了我当前项目的想法。

<contact-table [contacts]="connectedAccount$ |async"></contact-table>

export class AppComponent implements OnInit
{
  private connectedAccount$: Observable<Account>;
  constructor(private store:Store<any>) {
    this.connectedAccount$ = this.store
      .select(state=> state.connectedAccountReducer.connectedAccount);

    this.connectedAccount$
      .subscribe(account1=> {
       //the app prints any new account that comes up. It's working here.
       console.log(account1);
      });
  }
  public ngOnInit() {
    this.store.dispatch({
      type: updateConnectedAccount,
      payload: {
        connectedAccount: ACCOUNTS[0]
      }
    });
  }
}
