Node.js: how to limit the HTTP request size and upload file size?


I'm using Node.js and express.

I would like to limit the HTTP request size. Let's say, if someone sends me a HTTP request more than 2 MB then I stop the request right away. I looked at the code and I think if I change the core, I can do it. However, is there a way to set a max_request_size or soemthing like that?

It is kind of related to my second question. I'm using express to get an uploaded file from req.files. Is there a way to stop writing the file to the /tmp folder (which is the default upload behavior) as soon as the file size exceeds a certain file size?

Just an update (07-2014), as I'm not able to add comments:

As correctly noted above, newer Express versions have deprecated the use of the limit middleware and now provide it as a built-in option for the BodyParser middleware:

   var express    = require('express')
   var bodyParser = require('body-parser')

   var app = express()
   app.use(bodyParser.json({ limit: '5mb' }))
