NodeJS : Connect MongoDB and get Data from Collection

In any Web application , its important to connect to Database for data .

In MEAN , as we use MongoDB , so I will write code how a Node app can talk with MongoDB Database.

I have a Database named newDB and I have a collection named myColl in my local MongoDB server.

Like below , we can connect and get data from Mongo Server.

var MongoClient = require('mongodb').MongoClient;
MongoClient.connect('mongodb://localhost:27017/newDB'function(err , db) {
	if(err) {
		throw err;
	db.collection('myColl').findOne({} , function(err , doc){
		if(err) {
			throw err;
	console.dir("Called FindOne");

Hope this Helps.
