how to add query parameter to url in angular

// Make sure to import and define the Angular Router and current Route in your constructor
constructor(
  private router: Router,
  private route: ActivatedRoute
) {}

...

// Take current queryParameters from the activated route snapshot
const urlParameters = Object.assign({}, this.route.snapshot.queryParams);
