Node.jsMongoDB

Node.js can be used in database applications.

One of the most popular NoSQL database is MongoDB.

MongoDB

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

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

Or get started right away with a MongoDB cloud service athttps://www.mongodb.com/cloud/atlas.

Install MongoDB Driver

Let us try to access a MongoDB 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:\Users\Your Name>npm install mongodb

Now you have downloaded and installed a mongodb database driver.

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

let mongo = require('mongodb');
