Angular 14: Change Detection Not Triggering on Observable Stream Updates in Component
I need help solving I've been working on this all day and I tried several approaches but none seem to work. I'm facing an issue with Angular 14 where the change detection doesn't seem to trigger when an observable stream updates. I'm using a service to fetch a list of items and subscribe to this observable in my component. However, even when the data is updated, the view does not reflect these changes. I have tried various strategies such as using `ChangeDetectorRef` to manually mark for check, but none have worked so far. Here’s a snippet of how I'm currently subscribing to the observable: ```typescript import { Component, OnInit, ChangeDetectorRef } from '@angular/core'; import { MyDataService } from './my-data.service'; import { Observable } from 'rxjs'; @Component({ selector: 'app-my-component', templateUrl: './my-component.component.html', }) export class MyComponent implements OnInit { items$: Observable<Item[]>; constructor(private myDataService: MyDataService, private cdr: ChangeDetectorRef) {} ngOnInit() { this.items$ = this.myDataService.getItems(); this.items$.subscribe(data => { console.log('Data received:', data); // Tried marking for check here this.cdr.markForCheck(); }); } } ``` In my HTML template, I am using the async pipe to display the items: ```html <ul> <li *ngFor="let item of items$ | async">{{ item.name }}</li> </ul> ``` Even with the `ChangeDetectorRef` in place, there are times when the UI does not update despite the console showing the new data. I suspect this might have to do with the way observables are being handled or possibly some issue with how change detection is triggered in Angular. Any insights or strategies to resolve this would be greatly appreciated. Is there a better approach to ensure that my UI reflects the latest data updates from the observable? For context: I'm using Typescript on Ubuntu. Any ideas what could be causing this? This is part of a larger CLI tool I'm building. What am I doing wrong? My team is using Typescript for this service.
