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

Use raw-body. Most middleware (like limit) is no longer bundled with Express and must be installed separately. Here's an example.

var getRawBody = require('raw-body')
app.use(function (req, res, next) {
      getRawBody(
        stream = req,
        options = {
          length: req.headers['content-length'],
          limit: '100mb',
        },
        callback = function (err, reslt) {
          if (err) {
            return next(err)
          }
          next();
          console.log(req)
        })
    })

• Remember to add the router after the app.use

Express no longer allows you to explicitly set the limit using the traditional bundled middleware as show below.

app.use(express.limit('4M'));
