Node Busboy abort upload

Question

I\'m using busboy, writing my uploaded file to a buffer and performing some validation on it (width, height and filesize). I can\'t for the life of me figure out how to abo

Answer 1

The answer is simple one.

// do the required validation like size check etc.
if( size > 500000) 
{
    self.req.unpipe();
    return;
}

The context is this. I see in busboy code that busboy is implemented as WritableStream and underneath uses Dicer module for parsing which is also implemented as WritableStream. Flow is like this:

req stream ==> busboy ==> dicer ==> dicer raises events ==> busboy raises events on file ==> these events are consumed in your code.

To stop this whole flow of code - the above unpipe should do.
