How to send POST request to another node.js server

I make 2 servers

var express = require('express');
var querystring = require('querystring');
var http = require('http');

var app = express();
app.get('/', function (req, res) {
  var data = querystring.stringify({
    username: 'myname',
    password: 'pass'
  });

  var options = {
    host: 'localhost',
    port: 8081,
    path: '/demo',
    method: 'POST',
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded',
      'Content-Length': Buffer.byteLength(data)
    }
  };

  var httpreq = http.request(options, function (response) {
    response.setEncoding('utf8');
    response.on('data', function (chunk) {
      console.log("body: " + chunk);
    });
    response.on('end', function() {
      res.send('ok');
    })
  });
  httpreq.write(data);
  httpreq.end();
});

app.listen(8090, function(){
    console.log('Server start on 8090');
});

The second one is 

var express = require('express');
var app = express();

app.post('/demo', function(req, res){
    console.log('Body : ', req.body);
});

app.listen(8081, function(){
    console.log('Server Start on 8081');
});

I want to send the data from localhost:8090 to the localhost:8081.

But at the 2nd server side when I try to print req.body It shows me 

Server Start on 8081
Body :  undefined

Help me to find solution. And If you have better code then this then it will good for me.

Thank you for help in advance.

The reason why your body is undefined in your express server is because you're not using the body-parser middleware. Express cannot parse request body's for the Content-Type x-www-form-urlencoded like you have specified in your request. Also in your request you're not sending in data through the body of your request, you're sending it in the query string, so your Express Route needs to check the query string and not the body.

You'll need to make your Express look like this:

const express = require('express');
const bodyParser = require('body-parser');

const app = express();
const port = process.env.PORT || 1337;

app.use(bodyParser.urlencoded({ extended: true }); // Parse x-www-form-urlencoded

app.post('/demo', (req, res) => {
  console.log(`Query String: ${req.query}`);
  console.log(`Body: ${req.body}`);
});

app.listen(port, () => { 
  console.log(`Listening on ${port}`); 
});

You can do request like this

require('request').post(
    "localhost:8081/demo", 
    {form: 
        {
            username: "name",
            password: "any"
        }
    },
    function(error, response, body){
        console.log(body);
    }
);
