I can honestly say await/async in angular is really a great stuff, it reduces a lot of braces, improves readability and prevent a lot of human error. However, one thing puzzles me a lot. how can I use await/async inside subscribe.
let's say
@Injectable()
export class TableCom extends BaseCom {
public subject = new Subject<any>();
}
TableCom is a provider serves as a communicator between a signalr component and a page component.
so inside the page component constructor, it is using the observable subject to receive new data from signalr component as shown below.
constructor(protected nav: NavController,
protected db: Storage,
protected alert: AlertController,
protected order: OrderData,
protected translate: TranslateService,
public navParams: NavParams,
public toastCtrl: ToastController,
private table_data: TableData,
private load: LoadingController,
private http: Http,
private com_table: TableCom
)
{
super(nav, db, alert, order, translate, undefined, false);
this.previous_page = navParams.get('previous_page');
this.subscribe_table = this.com_table.Receive().subscribe(res =>
{
await this.SaveTableAsync(res.data);
this.ReadTableAsync();
});
}
the issue is that the this.ReadTableAsync() basically has to wait this.SaveTableAsync to be finished before starting. await can be achieved here ? thank you in advance !!
