great, thanx!

I've resolved the issue, but I've use hapi:

var serverOptions = {
payload: { multipart: 'file' },
cors: {
credentials: true,
additionalHeaders: ['X-Requested-With']
}
};

and the route (post):

payload: 'parse'

and then nodejs-imager which helps to upload into s3 in few lines:

imager.upload(req.payload.file.path, function (err, cdnUri, files) {
if (err) return req.reply({code: 200, message: err.message})
if (files.length) {
var avatar = { cdnUri : cdnUri, files : files }
}
req.reply({code: 200, image: avatar})
}, 'movie')
