angular2 map data as specific object type

Question

I created a very simple app based on the Angular2 tutorial.

To start, I have a very simple \"Book\" model:

 /**
 * book model
 */
export class Book          


        

Answer 1

Good practice is to consume data from GET response using

Observable

(regarding to Angular documentation https://angular.io/guide/http) And then:

// imports

import {HttpClient} from "@angular/common/http";

// in constructor parameter list

private http: HttpClient

// service method

getBook(): Observable {return this.http.get({url}, {options});}
