How to get data from BehaviourSubject in Angular?

I want to access to the locationRoot properties.
How can I do it?

[Service Code]

getCityByLocationRootName(locationRoot: LocationRoot) {
    const behaviourSubjectCity = new BehaviorSubject<City>(this.city);
    const url = this.API_GEOCODE + locationRoot.name + '&appid=' + this.API_KEY;
    this.httpClient
      .get<City>(url).subscribe({
        next: city => behaviourSubjectCity.next(city),
        error: error => console.error(error)
      });
    return behaviourSubjectCity;
  }

[Component Code]

getLocationRootByName() {
    const locationRoot = this.dataService.getCityByLocationRootName(this.locationRoot);
  }

>Solution :

You don’t need to use subject, when you can do

return this.httpClient.get<City>(url)

And after subscribe it into your component.

getLocationRootByName() {
    let locationRoot;
    this.dataService.getCityByLocationRootName(this.locationRoot).subscribe({
        next: city => locationRoot = city,
        error: error => console.error(error)
      });
}

If you want to handle error in your service, so you can use pipe to do that.
