Setting up MongoDB Atlas Nodejs Integration Simplified: 3 Easy Steps

The database industry has undergone a number of changes in recent years, resulting in a greater shift toward a Database as a Service (DBaaS) model versus On-Premise Infrastructure. Most business apps rely on Databases, and Cloud-based DBaaS services provide users with a Flexible, Scalable, and On-demand Platform that eliminates the need to set up costly physical hardware. MongoDB Atlas is a fully Cloud-based Database Service that hosts your data on MongoDB Instances. On the other hand, the Node.js driver provides an interface for connecting to and communicating with MongoDB Instances. 

Upon a complete walkthrough of this article, you will gain a holistic understanding of MongoDB Atlas and Node JS. This article will also provide you with a step-by-step guide on how to connect to MongoDB Atlas from a Node JS application and set up MongoDB Atlas Nodejs Integration.

Prerequisites

• An active MongoDB Atlas account.

How to Build the MongoDB Atlas Nodejs Integration?

Building the MongoDB Atlas Nodejs Integration is a fairly easy process. Follow the given three steps to set up MongoDB Atlas Nodejs Integration:

Step 1: Create a MongoDB Atlas Cluster

The first step involved in building the MongoDB Atlas Nodejs Integration requires you to create a new cluster. Follow the steps given below to do so:

• Log in to your MongoDB Atlas account using the appropriate credentials. If you have never created a Cluster, you will encounter a screen like this:

• Click on the green-colored Build a Cluster button to create a new cluster. Upon clicking, you need to select the Cloud Provider and Region. You can proceed by leaving other settings to their default state.

• Once you have selected the Cloud Provider and Region, MongoDB Atlas will take around 5-10 minutes to configure and create a new cluster.

Step 2: Add User and Whitelist IP address

Once you have successfully created a cluster, it’s time to add a Database User and IP address of your current machine. Follow the steps given below to do so:

• Navigate to the Database Access option and click on Add New Database User.
• Fill in the Username and Password fields.
• The next step is to Whitelist your IP address so that your machine can be recognized for regular access. To Whitelist an IP address, navigate to the Network Access option and click on Add IP Address.
• Now, click on Allow Access from Anywhere which sets the IP address to global access.

Step 3: Connect to your Database

• Head back to the home page of MongoDB Atlas and select the Clusters option.
• Now, click on the Connect Your Application option to set up a connection between your application and cluster using MongoDB’s native drivers.
• Select Node.js as the native driver and save the Connection String provided by MongoDB Atlas for further reference.

• It’s now time to use Mongoose to create your database connection. Install Mongoose in your project by using the npm install mongoose command. Copy and paste the code below into db.js.

//db.js

const mongoose = require('mongoose')

const url = `Connection String`;

const connectionParams={
    useNewUrlParser: true,
    useCreateIndex: true,
    useUnifiedTopology: true 
}
mongoose.connect(url,connectionParams)
    .then( () => {
        console.log('Connected to the database ')
    })
    .catch( (err) => {
        console.error(`Error connecting to the database. n${err}`);
    })

• Replace password with your own password and dbname with the name that you would like to give to your database. Once you have successfully executed the above code, you will see a Connected to the Database message on your console.

Once you have followed all the above steps in the correct sequence, you will be able to set up MongoDB Atlas Nodejs Integration in no time.
