This specification defines a profile of the XMPP stream initiation extension for transferring files between two entities. The protocol provides a modular framework that enables the exchange of information about the file to be transferred as well as the negotiation of parameters such as the transport to be used.
Include strophe.si-filetransfer.js in the head of your page. The will allow you to send and receive stream initiations. In order to actually transfer files, you'll need to also include a transport mechanism, like In-Band Bytestreams or Out-of-Band Data.

var connection = new Strophe.Connection();
var fileHandler = function (from, sid, filename, size, mime) {
// received a stream initiation
// be prepared
};
connection.si_filetransfer.addFileHandler(fileHandler);
// send a stream initiation
connection.si_filetransfer.send(to, sid, filename, size, mime, function (err) {
if (err) {
return console.log(err);
}
// start sending file
});
