Tips for dynamically updating page titles in the browser tab using Angular 8

In the application I am developing, there is a list of employees that when clicked on, navigates to that employee's details. I want the browser title to display information specific to each employee, such as "Employee Name: Employee Number". The same functionality should apply to the list of departments as well; when navigating to the department component, the browser title should show "Department Name: Department Number".

I am looking for suggestions on how to achieve this in a generic way rather than setting the title individually for each component.

Angular's TitleService allows for dynamic page title changes.

To use it, simply import the Title module:

import { Title } from '@angular/platform-browser';

In a custom service, you can monitor route changes, retrieve the current route, and update the title based on the router data:

public title: string = '';

constructor(private router: Router,  
    private activatedRoute: ActivatedRoute,  
    private titleService: Title) {}  

ngOnInit() {  
    this.router.events.pipe(  
        filter(event => event instanceof NavigationEnd),  
    ).subscribe(() =>
        this.titleService.setTitle(this.title));
}  

getChild(activatedRoute: ActivatedRoute) {  
    if (activatedRoute.firstChild) {  
        return this.getChild(activatedRoute.firstChild);  
    } else {  
        return activatedRoute;  
    }
}

You can customize the title for each component by setting it in the constructor of your custom service:

constructor(private customService: CustomService) {
    this.customService.title = 'Your desired title';
}

It's important to keep in mind that the approach suggested by Leonardo for the personalized feature won't be successful. While ngOnInit may not do the trick, ngOnDestroy could hold the key. The solution lies in relocating the subscription process to the constructor.
