export class DemoService extends RESTClient {

  constructor(protected http: Http) {
    super(http);

    // Optional
    this.withCredentials = true;
  }

  protected requestInterceptor(req: Request): Observable<Request> {
    return super.requestInterceptor(req); // wraps Observable.of
  }

  protected responseInterceptor(res: Observable<Response>): Observable<Response> {
    return res;
  }

  @POST('/posts')
  @Produces<Post>()
  public createPost(@Body post: Post): Observable<Post> {

  @Input() public demoList: Post[] = [];

  constructor(public demoService: DemoService) {
    this.getPosts();
  }

  createPost() {
    this.demoService.createPost(this.demoPost);
  }

  getPosts() {
    this.demoService.getPosts().subscribe(posts => {
      this.demoList = posts;
