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

Question

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 r

Answer 1

Express uses Connect, which has a limit middleware available. You can use this in your Express app by doing something like this:

app.use(express.limit('2mb'));

That, for example, would limit all HTTP requests to 2 MB. Since uploaded files are part of the HTTP request, any file upload larger than 2 MB would be aborted as well.
