Need to document how to handle errors

It throws some error but you don’t know how to handle them…

such as this:

• Missing Content-Type
• Unsupported content type
• Multipart: Boundary not found

I have this code but it never fire this event

busboy.on('error', function (err) {
    console.error('Error while parsing the form: ', err);
    // some code
})

I’d like docs on error handling recommendations for as well. For example. When parsing a field ab exception might be thrown, but calling res.send() there won’t stop the control flow, as handlers will continue to fire for other fields that get parsed, resulting in accidentally sending headers multiple times.

For others struggling to understand how Busboy errors should be handled, take a look at Multers-s code or use Multer instead - https://github.com/expressjs/multer/blob/master/lib/make-middleware.js#L45
