Example created Database in mongoDB with nodejs

Node.js can be used in database applications.

One of the most popular NoSQL database is MongoDB.


To be able experiment with the code examples, you will need access to a MongoDB database.

You can download a free MongoDB database at https://www.mongodb.com.

Install MongoDB Driver

Let us try to access a MongDB database with Node.js.

To download and install the official MongoDB driver, open the Command Terminal and execute the following:

Download and install mongodb package:


C:\ Nodejs>npm install mongodb


Now you have downloaded and installed a mongodb database driver.

Node.js can use this module to manipulate MongoDB databases:


var mongo = require('mongodb');


Creating a Database

To create a database in MongoDB, start by creating a MongoClient object, then specify a connection URL with the correct ip address and the name of the database you want to create.

MongoDB will create the database if it does not exist, and make a connection to it.



var MongoClient = require('mongodb').MongoClient;

var url = "mongodb://";

MongoClient.connect(url, function(err, db) {

  if (err) throw err;

  console.log("Database created!");






C:\ Nodejs>node mongodbCreatedDB.js

Database created!
