I have a canActivate method that requests the user from the server. at the moment everything works, but there is one not very pleasant moment, while the application is loading, the base preloader is spinning, then a blank screen while waiting for the server response. How to make the preloader spin until the server response arrives?

<body>
  <app-root>Loading...</app-root>
</body>

I need Loading... to glow before the response from the server comes.

export class Login{
     
      result:Array<Object>; 
      constructor(http: Http,private dd:dataService) { 
        
      this.dd.showLoader();
        
       this.dd.fetchData().subscribe((result) =>{ 
                    this.result =result
                    },
                    (err)=>console.log(err),
                    ()=>{console.log("Done")
                       this.dd.hideLoader();
                    }); 
                      
                      
       }
  }

So? Run the preloader, and hide it in the response from the service upon receipt
