Providers

Question 1

Say I have a Rails backend I want to make a request to, in order to fetch all restaurants, how could I receive this data in a component? Write answer in bullet points to make things easier.

Answer 1

1. Create service and import it into app module and providers
2. In service import Angular2TokenService and add it to your constructor
3. Add a method that could look like so:
   getRestaurants() {
   this._tokenService.get(api-base + route-url).map(res => res.json())
   }
4. Import service into component to display restaurants
5. Add service to component’s constructor
6. Add method in ngOnInit or constructor to make call to service getRestaurants method like so:
   allRestaurants() {
   this.restaurantService.getRestaurants().subscribe(data => this.restaurants = data)
   }
