What is the best way to fully reload an Angular component when the route is changed?

I'm looking for a way to reload or refresh a sidebar component when the route changes. Below is the code I currently have:

  constructor(
    private auth: AuthService,
    private router: Router,
    private changeDetector: ChangeDetectorRef
  ) {
    this.auth.currentUser.subscribe(x => this.userData = x);
    this.router.events.subscribe((event) => {
      if (event instanceof NavigationStart) {
        this.changeDetector.detectChanges();
        console.log('enter');
      }
    });
  }

The 'enter' log is displayed, but the component is not reloaded. Can anyone provide an example of how to achieve this?

Answer №1

Typically, component routing in Angular does not trigger a reload since it operates as a single page application. However, you have the option to force your components to reload in order to decrease browser size, if necessary.

To achieve this, use href and your path name instead of routerLink on your sidebar anchor links. This will cause your component to reload every time it is clicked, loading all your JavaScript from the server. Keep in mind that if you are implementing lazy loading, this may not be the preferred method. Using href can help reduce browser RAM usage upon each click, but it will not retain any previous data.

Ultimately, using href may be the solution for your specific situation, but be certain that reloading your components is necessary.

I hope this explanation proves useful - Happy Coding:)

Answer №2

To refresh the entire page, simply utilize

window.location.reload();
