well to do this, you have to introduce a protocol how to format the data
sent over tcp. this is what http does. You could use a
JSONStream https://github.com/dominictarr/JSONStream
where you just pipe the it to/from the socket and your json object could be
like: {filename:'a string of file', file:myFileBuffer.toString('ensoding
you like')}
