I could not find a way to upload files via your socket-connection. http://sailsjs.org/documentation/reference/request-req tells me this is not supported for websockets.
I added an upload function to your DataService.js:
where Upload is from ng-file-upload (https://github.com/danialfarid/ng-file-upload).
I don't have time to make a proper pull-request and I am not sure whether or not this is the way to do it. It solved my problem though.
