import {HttpServiceService} from './../http-service.service';

@Component({
  selector: 'app-list',
  templateUrl: './list.component.html',
  styleUrls: ['./list.component.scss']
})
export class ListComponent implements OnInit {

  constructor(
     private http: HttpServiceService,
     private zone: NgZone
    ) { }
  brews: object;
  ngOnInit(): void {
      this.http.getPeople().subscribe(data => {
      this.brews = data;
      alert(JSON.stringify(this.brews));
      console.log(this.brews);
      });
