You could use the multiparty module as follows

var multiparty = require('multiparty');

exports.parseForm = function (req, res) {

   var form = new multiparty.Form();
   form.parse(req, function(err, fields, files) {

     //here you can read the appropriate fields/files

   });
};

Also be sure you are setting the enctype correctly in your html

<form role='form' method='post' enctype="multipart/form-data">

When I used this it was to submit multiple text fields, and a single image file, via the HTML form. Then in my parseForm function I would bundle these into a single object to be saved to mongo as follows

form.parse(req, function(err, fields, files) {
      var temp = fields;
      temp.image = {};
      temp.image.data = fs.readFileSync(files.image[0].path);
      temp.image.contentType = 'image';
      var product = new Product(temp);
      product.save();
      res.redirect('/');
});
