The data remains undefined even after being initialized in the constructor

My goal is to extract queryParams from a URL and leverage that information to resolve data in the following manner:


data = {
  searchValue: null || undefined
};
constructor(private http: HttpClient, private route: ActivatedRoute) {
  route.queryParams.subscribe(params => this.data.searchValue = params.search);
}

resolve(
  route: ActivatedRouteSnapshot,
  state: RouterStateSnapshot
): Observable<any> {
  console.log(this.data);
  if (!this.data) {
    throwError(console.error());
}

Even though I set the data in the constructor, it continues to log as undefined. I'm uncertain about why it's not functioning properly, and I would greatly appreciate if someone could elaborate on my mistake and provide guidance on how to address the issue.

Answer №1

It is recommended to utilize the snapshot property of the ActivatedRoute.

 constructor(private http: HttpClient, private route: ActivatedRoute) {
    this.data.searchValue = this.route.snapshot.queryParams['search'];
  }
