  beforeHook: BeforeHookFunction;

  constructor() {
    this.baseUrl = 'http://api.geonames.org';
    this.afterHook = (res: Response) => {
      return res.json().geonames;
    };
    this.beforeHook = (req: Request) => {
      //just logging
      console.log(req);
      return req;
    }
    this.errorHook = (req: Request) => {
