interface IHeaders {
  "x-ego-1": string;
  "x-ego-2": number;
  "x-ego-3": boolean;
}

@Controller()
export default class IndexController extends ControllerBase {
  @GET('/foo/:bar/buzz')
  async getBar(
    @Headers(({ key, source }) => {
      if (key === 'x-ego-2') {
        return Number(source)
      } else if (key === 'x-ego-3') {
        return Boolean(source)
      }

      return source
    }, 'x-ego-1', 'x-ego-2', 'x-ego-3') importedHeaders: IHeaders,

    @Response() response: IHttpResponse
  ) {
    response.write(`x-ego-1: ${importedHeaders['x-ego-1']} (${typeof importedHeaders['x-ego-1']})\n`)
    response.write(`x-ego-2: ${importedHeaders['x-ego-2']} (${typeof importedHeaders['x-ego-2']})\n`)
    response.write(`x-ego-3: ${importedHeaders['x-ego-3']} (${typeof importedHeaders['x-ego-3']})\n`)
  }
