Use Node.js? Want to learn MongoDB? This is the blog series for you! In this Quick Start series, I’ll walk you through the basics of how to get started using MongoDB with Node.js. In today’s post, we’ll work through connecting to a MongoDB database from a Node.js script, retrieving a list of databases, and printing the results to your console. Prefer to learn by video? I've got ya covered. Check out the video below that covers how to get connected as well as how to perform the CRUD operations.
Set upBefore we begin, we need to ensure you’ve completed a few prerequisite steps. Install Node.jsFirst, make sure you have a supported version of Node.js installed. The current version of MongoDB Node.js Driver requires Node 4.x or greater. For these examples, I've used Node.js 14.15.4. See the MongoDB Compatability docs for more information on which version of Node.js is required for each version of the Node.js driver. Install the MongoDB Node.js DriverThe MongoDB Node.js Driver allows you to easily interact with MongoDB databases from within Node.js applications. You'll need the driver in order to connect to your database and execute the queries described in this Quick Start series. If you don't have the MongoDB Node.js Driver installed, you can install it with the following command.
At the time of writing, this installed version 3.6.4 of the driver. Running Create a free MongoDB Atlas cluster and load the sample dataNext, you'll need a MongoDB database. The easiest way to get started with MongoDB is to use Atlas, MongoDB's fully-managed database-as-a-service. Head over to Atlas and create a new cluster in the free tier. At a high level, a cluster is a set of nodes where copies of your database will be stored. Once your tier is created, load the sample data. If you're not familiar with how to create a new cluster and load the sample data, check out this video tutorial from MongoDB Developer Advocate Maxime Beugnet. Get started with an M0 cluster on Atlas today. It's free forever, and it's the easiest way to try out the steps in this blog series. Get your cluster’s connection infoThe final step is to prep your cluster for connection. In Atlas, navigate to your cluster and click CONNECT. The Cluster Connection Wizard will appear. The Wizard will prompt you to add your current IP address to the IP Access List and create a MongoDB user if you haven't already done so. Be sure to note the username and password you use for the new MongoDB user as you'll need them in a later step. Next, the Wizard will prompt you to choose a connection method. Select Connect Your Application. When the Wizard prompts you to select your driver version, select Node.js and 3.6 or later. Copy the provided connection string. For more details on how to access the Connection Wizard and complete the steps described above, see the official documentation. Connect to your database from a Node.js applicationNow that everything is set up, it’s time to code! Let’s write a Node.js script that connects to your database and lists the databases in your cluster. Import MongoClientThe MongoDB module exports
Create our main functionLet’s create an asynchronous function named
The first thing we need to do inside of Note: the username and password you provide in the connection string are NOT the same as your Atlas credentials.
Now that we have our URI, we can create an instance of MongoClient.
Note: When you run this code, you may see DeprecationWarnings around the URL string Now we're ready to use MongoClient to connect to our cluster.
Now we are ready to interact with our database. Let's build a function that prints the names of the
databases in this cluster. It's often useful to contain this logic in well named functions in order to improve the readability of your codebase. Throughout this series, we'll create new functions similar to the function we're creating here as we learn how to write different types of queries. For now, let's call a function named
Let’s wrap our calls to functions that interact with the database in a
We
want to be sure we close the connection to our cluster, so we’ll end our
Once we have our
Putting it all together, our
List the databases in our clusterIn the previous section, we referenced the This function will retrieve a list of databases in our cluster and print the results in the console.
Save Your FileYou’ve been implementing a lot of code. Save your changes, and name your file something like Execute Your Node.js ScriptNow you’re ready to test your code! Execute
your script by running a command like the following in your terminal: You will see output like the following:
What’s next?Today, you were able to connect to a MongoDB database from a Node.js script, retrieve a list of databases in your cluster, and view the results in your console. Nice! Now that you're connected to your database, continue on to the next post in this series where you'll learn to execute each of the CRUD (create, read, update, and delete) operations.
