Connecting to MongoDB in Node.js
Learn about the Node.js driver for MongoDB and how to use it to connect to your Node.js applications.
Connecting to MongoDB in Node.js
Unit Overview
In this unit, you will learn about the Node.js driver for MongoDB and how to use it to connect to your Node.js applications. First, we'll use the Yarn package manager to install the Node.js MongoDB driver. Next, we will explore best practices when creating a MongoClient. Finally, we'll troubleshoot a few of the most common connection and authentication issues.

Hi there, and welcome! In this unit, you’ll learn how to connect a MongoDB Atlas cluster to a Node.js application by using the official Node.js driver from MongoDB.
I’m John
It’s easy to connect a Node application to a MongoDB database. All we need is a connection string, the Node.js MongoDB driver, and an application.
By using the driver, you can seamlessly integrate your Atlas cluster into a variety of applications.
For example, we can use Atlas to host data that’s delivered to users by using a REST API built with Node.js.
MongoDB is powerful on its own. But, pairing it with a runtime environment such as Node.js, which runs JavaScript outside the browser, opens up even more possibilities. We’ll explore these possibilities throughout the course.
The lessons in this unit consist of video lectures followed by quiz questions or labs so that you can practice what you learned.
First, you will learn about MongoDB drivers and how they are used to connect applications to MongoDB.
Then, we’ll install the MongoDB Node.js driver by using the npm package manager. We’ll create a MongoClient instance in our Node.js code and use it to connect to our Atlas cluster.
Finally, we’ll troubleshoot a few of the most common connection and authentication issues.
Before you begin this unit, you should have a basic understanding of: Node.js, MongoDB databases and the document model, and Atlas, the MongoDB developer data platform.
You will also need to set up an Atlas account with a free tier cluster.
By the end of this unit, you will be able to install the MongoDB Node.js driver, use your connection string to connect your application to the database, and troubleshoot common connection and authentication errors.
Let’s get started!
