Question: Is there a way to premature end parsing

[brupxxxlgroup]

After I have received the first file I would like to stop busboy and not process any other field or file. Is there a manual way how to do it? I don't want to set any limits btw.

Just stop writing to the busboy stream.

And how you do that when the HTTP request ist the incoming source?

I'm not sure what you mean. The source of your data doesn't matter, all you need to do is stop calling .write() on your busboy object either explicitly or implicitly.
