Question

pros and cons of using bodyparser nodejs file uploads

So what are the pros and cons of using bodyParser for file uploads?

I mean with bodyParser I get the file into a /var/ directory and then I move it to my directory once its uploaded, it gives me easy access to the name file and other information, but without bodyParser I can do stuff to the files once the 'done' event is triggered..

Is there a way to know when to use bodyParser, and when no to when it comes to files?

node.js
restify

If you are working with express, you are able to bind a middleware before the bodyParser.

Something like this:

app.use( function( req, res, next ) {
    ... code here runs before bodyparser
    next();
    ... code here runs on the way back (only when there is no error)
});
app.use( express.bodyParser() );
app.use( function( req, res, next ) {
    ... code here runs after bodyparser, before route
    next();
    ... code here runs on the way back (only when there is no error)
});

In this case, you would be able to use both.
