Within Express 3, you can pass parameter to the bodyParser as {defer: true} - which in term defers multipart processing and exposes the Formidable form object as req.form. Meaning your code can be:

...
app.use(express.bodyParser({defer: true}));

...
// your upload handling request 
app.post('/upload', function(req, res)) {
    var incomingForm = req.form  // it is Formidable form object

    incomingForm.on('error', function(err){

          console.log(error);  //handle the error

    })

    incomingForm.on('fileBegin', function(name, file){

         // do your things here when upload starts
    })


    incomingForm.on('end', function(){

         // do stuff after file upload
    });

    // Main entry for parsing the files
    // needed to start Formidables activity
    incomingForm.parse(req, function(err, fields, files){


    })
}
