Parsing Json data in NodeJS

Our Goals –

"name": "myschool",
"version": "1.0.0",
"description": "My First Project in NodeJS",
"main": "app.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
"author": "Tanmay Sarkar",
"license": "ISC",
"dependencies": {
"body-parser": "^1.17.0",
"express": "^4.15.0"

4. Open “app.js” file and paste the following code.

5. Now run this app using “node app” command at command prompt.

Source Code :

var express = require('express');
var parser = require('body-parser');
var app = express();
var person ={
	fname : 'Tanmay',
	lname : 'Sarkar',
	address : {
		add1 : 'my home address',
		add2 : 'my office address'
	console.log('user accessing json parsing page');
	console.log('server running on port 5000');
