Correct way Provide DomSanitizer to Component with Angular 2 RC6


I'm attempting to use DomSanitizer to sanitize a dynamic URL within a Component using I can't seem to figure out what the correct way to specify a Provider for this service is.

I'm using Angular 2.0.0-rc.6

Here's my current component:

@Component({
    templateUrl: './app.component.html',
    styleUrls: [ './app.component.css' ],
    providers: [ DomSanitizer ],
})
export class AppComponent implements OnInit
{
    public url: SafeResourceUrl;

    constructor(private sanitizer: DomSanitizer) {}

    ngOnInit() {
        let id = 'an-id-goes-here';
        let url = `https://www.youtube.com/embed/${id}`;

         this.videoUrl = this.sanitizer.bypassSecurityTrustResourceUrl(url);
    }

    ngOnDestroy() {}
}

This results in the error this.sanitizer.bypassSecurityTrustResourceUrl is not a function at runtime.

Could someone show me an example of how to properly provide a Provider for DomSanitizer? Thanks!


Solution

  • You don't need to declare providers: [ DomSanitizer ] anymore.
    Just need to import DomSanitizer as shown below,

    import { DomSanitizer, SafeResourceUrl, SafeUrl} from '@angular/platform-browser';
    

    in component inject it through a constructor as below,

    constructor(private sanitizer: DomSanitizer) {}
