Answer 1

install npm install body-parser

and use this snippet,

var express = require('express')
var bodyParser = require('body-parser')
 
var app = express()
 
// create application/json parser
var jsonParser = bodyParser.json()
 
to get json response
app.use(jsonParser, function (req, res) {
  console.log(req.body); // or console.log(res.body);
})
