Casting a type (interface) via map to observable

Question

I\'ve been learning TypeScript with Angular. And currently I stuck as this moment. Previously I used subscribed method and everything works flawlessly, but not I decided to

Answer 1

Given that your rest service or provider returns a Restaurant in this format (i've always used classes not interfaces, sorry i can't provide any help with this distinction, so in my example Restaurant is a class).

export class Restaurant { 
    _id: string; 
    name: string; 
    description: 
    string; email: 
    { 
        address: string; 
        confirmation_code: string;
         confirmed: boolean; 
    }; 
    auth: { 
        password: string; 
    }; 
    branches: Branch[];
    menus: Menu[];
    images: File[];
    cuisines: Cuisine[];
    blocked: boolean;
    created: Date;
    business_hours: object; 
}

You should be able to have angular serialise the response for you as an example:

getRestaurant(): Observable {
  return this.http.get(environment.api + "/restaurant");
}

That is given you also have a also imported the other types Branch, Menu, File, Cuisine into the typescript file containing the restaurant. for example branch would look like

export class Branch {
   // branches properties
}
