Question

I have a flatiron app that now needs to be expanded to handle multipart/form-data upload of images.

How does one handle file uploads in a flatiron app? union/director seem to ignore multipart/form-data, and all my attempts to integrate formidable have failed – I assume this is because of the actions union performs before formidable gets a hold of the request object.

I have tried normal and streaming: true routes, as well as raw handling in the before array.

I can’t be the only person who needs this, so it’s probably been addressed and I apologize. I just can’t find any reference materials.

You can use union with connect.multipart (or bodyParser) which already uses node-formidable.

var connect = require('connect'),
    union = require('union');


var server = union.createServer({
  buffer: false,
  before: [
    connect.bodyParser(),
    function(req, res) {
                if (req.method==='POST'){
                        console.log(req.files);
                        res.end('Done');
                }else{
                        res.writeHead(200, { 'Content-Type': 'text/html' });
                        res.end('<form method="post" enctype="multipart/form-data">' +
                                '<input type="file" name="file" />' +
                                '<input type="submit" value="Upload" />' +
                                '</form>');
                }
    },
  ]
}).listen(8000);
