I try to add a decorator to express-js handler, that has been already wrapped into. The context of the controller class is lost.

express-decorator-try-1.ts

  @web.get('/quotes')
  @IsAuthenticated()
  public getQuotesAction(request: Request, response: Response) {
    ...
  }

let IsAuthenticated = () => {
  return (target: Object, key: string | symbol, descriptor: TypedPropertyDescriptor<Handler>) => {
    let standardHandler: Handler = descriptor.value;

    // descriptor.value
    let newHandler = (request: IAppRequest, response: Response, next: NextFunction):any => {
      if (!request.context.forexTokenData || !request.context.forexTokenData.id) {
        response
          .status(403)
          .json({
            message: 'The user have to be authenticated.'
          })
      }
      else {
        let data = web.getRouteMetadata(target);
        let data1 = web.getRoutes(target);
        standardHandler.bind(data);
        standardHandler(request, response, next);
        // standardHandler.apply(this, [request, response, next]);
      }
    };

    descriptor.value = newHandler;
  };
};
