I wrote a module for this purpose.

socket.io-stream

Answer 4

In May of 2014 with release version 1.0 of socket.IO, binary support has been added to the library.

Socket.IO now supports emitting Buffer (from Node.JS), Blob, ArrayBuffer and even File, as part of any datastructure

It's all due to low level api which is provided by engine.io.

Here is a npm module I wrote that will implement Socket.IO file uploading in your application:

Socket.IO File Upload

All you need to give the module is your middleware, your socket, and the file input or drop zone used for uploading files. It will also save the files if you give it a directory. The module takes care of the rest.
