Is it possible to write to memory rather then fs?

[eugenekgn]

I want to write/pipe to some sort of buffer rather than file system, and then send it of to the server in binary format, how would one do that?

Just pipe it to your writable stream?

Here is a good article explain about creating writable memory stream: http://codewinds.com/blog/2013-08-19-nodejs-writable-streams.html

thanks everyone for chiming in here. closing but most any writable stream should work just fine. the beauty of steams is that the medium doesnt matter as much.
