Jul 11, 2016 · To handle HTTP POST requests in Express.js version 4 and above, you need to install the middleware module called body-parser. body-parser extracts the entire body portion of an incoming request stream and exposes it on req.body. The middleware was a part of Express.js earlier but now you have to install it separately.
I tried doing response.write(request.body) but Node.js throws an exception saying "first argument must be a string or Buffer" then goes to an "infinite loop" with an exception that says "Can't set headers after they are sent."; this also true even if I did var reqBody = request.body; and then writing response.write(reqBody).
First, you'll need to add body-parser to the dependencies property of your package.json, and then perform a npm update. To handle multi-part form data, the bodyParser.urlencoded() body parser will not work. See the suggested modules here for parsing multipart bodies.
It's now built-in with new versions of Express, you can access request body just like this only using express: app.use(express.urlencoded({extended: true})); app.use(express.json()) // To parse the incoming requests with JSON payloads. Hence, you can now uninstall body-parser using npm uninstall body-parser.

May 8, 2015 · Do not use body-parser anymore. Since Express 4.16+ the body parsing functionality has become builtin with express.
