  clients:Clients[];

  constructor(private http:HttpClient) { }

      },
      phone: {
        title: ' الهاتف'
      },
      address: {
        title: ' العنوان'
      },
      nots: {
        title: 'ملاحظات'
      }
    }
  };
  dataMain = [
    {
      index:1,
      id:"",
      name: "",
      phone:"",
      address: "",
      nots: "",
    }

  ];
  // end main stores tbl

  private myForm: FormGroup;

  constructor(private formBuilder: FormBuilder,private Service:ClientsService) { }


  ngOnInit() {

    this.Service.getAllClients();

  }

Answer 1

public getclients():Observable<any[]> { return this.http.get<any[]>(this.url) .pipe( //catchError(this.handleError<client[]>('getclients', []))

  // catchError(this.handleError)
 );
   

}
