  @BeforeMiddleware(
    uploader.buildUploadEndpoint({ authorizedExtensions: ['jpeg', 'png']})
  )
  @Post('/')
  async uploadRoute() {
    console.log('uploaded files')
    return {}
  }

  /**
   * download route
   * Params: {
   *  key: 'filename.jpeg'
   * }
   */
  @Get(':key', { bodyFormat: BodyFormat.AUTO, rawHandler: true })
  downloadRoute() {
    return uploader.buildDownloadEndpoint({
      retrieveKeyCallback: async (req: any) => {
        return req.params.key;
      },
    });
  }

  /**
   * download route
   * Params: {

  @Delete(':key', { rawHandler: true })
  deleteRoute() {
    return uploader.buildDeleteEndpoint({
