get json from a post request to a nodejs server

Where in the request object is the json?

For example I know I can use body-parser to do this

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());


app.post('/', function(req, res){
    console.log(req.body)
    res.json({ message: 'goodbye'})
})

And start my server and hit it with

curl -H "Cont/json" -X POST -d '{"username":"xyz"}' http://localhost:3000/

but is there a way to do it without the body parser includes? Can I just see the json in the request?

You could do it through node stream as below

app.post('/', function(req, res){
    var body = "";
    req.on("data", function (data) {
        body += data;
    });
    req.on("end", function() {
        console.log(JSON.parse(body));
        res.json({ message: 'goodbye'})
    });
})

Yep, you can

//pipe to any writable stream req.pipe(process.stdout); Sure if u want - u may save it to string using something like this

  var tmpstr = "";
  req.on("data", function (data) {
    tmpstr += data;
  });
  req.on("end", function() {
   //do stuff
   console.log("\ndata length is: %d", tmpstr.length);
  });
