What changes can be implemented to convert this function to an asynchronous one?

Is it possible to convert the following function into an asynchronous function?

  getHandledSheet(): void {
    this.timesheetService.getAllTimesheets().subscribe({next: (response: TimeSheet[]) => {this.timesheetsHandled = response.filter(sheet => sheet.status == 'HANDLED') }})
  }

Answer №1

In line with Matthieu's response, with adjustments for the syntax errors:

const timesheetObservable = this.timesheetService.getAllTimesheets();
const timesheets = await firstValueFrom(timesheetObservable);
this.handledTimesheets = timesheets.filter(sheet => sheet.status == 'HANDLED');

Answer №2

The firstValueFrom function promises to deliver the initial value emitted by the Observable

Upon receiving the promise from this.timesheetService.getAllTimesheets(), the next event containing an array of TimeSheet objects is processed through a filter operation to assign only those with a status of 'HANDLED' to the this.timesheetsHandled variable.
