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

I think you should declare an interface Book instead of class book:

export interface Book {
    public id;
    public title:string;
    public pages:Array;
}

In your service:

//get one record
return this._http.get('getBook/1')
        .map(function(res){
            return  res.json();
        });

//get multi record
return this._http.get('getBooks')
        .map(function(res){
            return  res.json();
        });
