The Angular component route is not refreshed, terminated, and reloaded

Encountered an issue with Angular 2+ related to loading a component, navigating to another route, and then reloading the component.

The code below loads an array that is then displayed using ngFor.

this.sub = this.subjectsService.getAllSubjects().subscribe(subjects => {
  this.subjects = subjects;
});

Adding an item during the initial load works correctly. However, upon navigating to a different component and returning back, any added items do not appear in the list.

I verified that the array is reset within the subscribe function, but it seems that Angular is not updating the HTML content. Any insights into why this behavior occurs?

Answer №1

To address the points raised in the previous comments, it's important to consider unsubscribing. Below is a simple illustration for guidance.

import { OnDestroy } from '@angular/core';


class CustomClass implements OnDestroy {

  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}
