Connect

noop()

noop middleware.

Source

function noop(req, res, next) {
  next();
}

Multipart

Parse multipart/form-data request bodies,
providing the parsed object as req.body
and req.files.

Configuration

The options passed are merged with formidable's
IncomingForm object, allowing you to configure the upload directory,
size limits, etc. For example if you wish to change the upload dir do the following.

app.use(connect.multipart({ uploadDir: path }));

Options

limit byte limit defaulting to none
defer defers processing and exposes the Formidable form object as req.form. next() is called without waiting for the form's "end" event. This option is useful if you need to bind to the "progress" event, for example.

Object options
returns Function
