implementing TypeScript class properties being undefined when using async methods in Angular service
Could someone explain I'm a bit lost with I can't seem to get This might be a silly question, but I'm working with a question with class properties in my Angular service when using async methods. I've defined a class property to hold data fetched from an API, but when I try to access this property in my component after calling the async method, it appears to be undefined. Here’s the relevant part of my code: ```typescript import { Injectable } from '@angular/core'; import { HttpClient } from '@angular/common/http'; import { Observable } from 'rxjs'; @Injectable({ providedIn: 'root' }) export class DataService { private data: any; constructor(private http: HttpClient) {} async fetchData(): Promise<void> { this.data = await this.http.get('https://api.example.com/data').toPromise(); } getData() { return this.data; } } ``` In my component: ```typescript import { Component, OnInit } from '@angular/core'; import { DataService } from './data.service'; @Component({ selector: 'app-my-component', template: '<div>{{ data }}</div>', }) export class MyComponent implements OnInit { data: any; constructor(private dataService: DataService) {} async ngOnInit() { await this.dataService.fetchData(); this.data = this.dataService.getData(); console.log(this.data); // This logs 'undefined'! } } ``` I expected `this.data` to contain the response from the API, but it logs `undefined`. I've tried checking if the HTTP call is successful by adding a console log in `fetchData`, and it shows that the data is fetched correctly. However, it seems like the `data` property isn't being set before I try to access it in `ngOnInit`. Is there something I'm missing regarding the timing of async operations in TypeScript and Angular? Any insights would be appreciated! For context: I'm using Typescript on Ubuntu. Thanks in advance! This issue appeared after updating to Typescript stable. Thanks, I really appreciate it! Thanks in advance!
