    },
}
res.send( data );

Answer 1

You can use res.sendFile and use the header to send some data along.

// res.sendFile(path [, options] [, fn])

let options = {
  headers: {
      'TheDataYouWantToSend': Date.now() // for example a timestamp
  }
}

req.sendFile(absolutePathToFile, options)

I hope this helps
