Answer 1

The bodyParser middleware does not parse POSTed binary data. When i tried base64 encoded strings, it would show up as the object name in a JSON object, something like {"data":}, obviously expecting POST-data in the form name=value.

There might be a middleware that deals with binary data, or you can access the raw data by binding to the "data" event and stack the received chunks into a buffer using the method described in the ProtocolBuffers.js wiki.

This is using the vanilla http module without express, but should work anyway.
