Answer 1

On the parent module create a provider for API_BASE_URL

export function getBaseUrl(): string {
  return AppConsts.baseUrl;
}

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule],
  providers: [{ provide: API_BASE_URL, useFactory: getBaseUrl }],
   bootstrap: [AppComponent]
})
export class AppModule {}

and then define a AppConsts class with static properties as such

export class AppConsts {
  static baseUrl = "your_api_base_url"; 
}

Worked for me, hope it help. This solution is based on aspnet boilerpate angular project, which for me give the best standards on architecture. I leave you here the url for the angular project + the url for this specific code.
