Below is an asynchronous function that was designed to populate the userList through the backend. However, when it is called using await this.getUsers(); within the ngOnInit method, the userList returns as an Observable. What crucial part seems to be missing here?
async getUsers(): Promise<void> {
if (this.empId) {
this.userList = await this.empService.getEmpUsers(this.empId);
console.log(this.userList); // return Observable {}
}
}
Angular's HttpClient always delivers an Observable. To convert it into a promise, utilize either RxJS 6 .toPromise() or RxJS 7:
async retrieveUsers(): Promise<void> {
if (this.empId) {
this.userList = await firstValueFrom(this.empService.obtainEmpUsers(this.empId))
}
}
