How to use with form upload and express 4?

I’m trying to use this to upload a file via a form post. It worked fine using express 3 but with express 4 the request.files object is empty. There have been suggestions online to use multer or busboy but I cant figure out how to implement them with s3-uploader. Here is a copy of upload function

exports.upload = function (req, response) {
    var filepath = req.files.image.path;
    var s3config = require('../config/aws.json');
    var client = new Upload('bucket-name', {aws: s3config})
    client.upload(filepath, {}, function (err, versions, meta) {
    });
}

req.files object is always empty. Any suggestions on how I get that object to contain the file info?

It can work with express v4 but you will need a middleware for handling multipart/form-data. (like multer). It will populate req.files/req.file. Can you add this and try again?
