Deploying a Node.js App from a Monorepo on AWS Elastic Beanstalk

AWS Elastic Beanstalk (EB) is a powerful platform that simplifies deploying and managing web applications. However, when working with a monorepo that has multiple projects, it can become challenging to serve a specific application from a subdirectory. In this guide, we’ll guide you through the process of configuring your AWS Elastic Beanstalk environment to serve a Node.js application located in a subdirectory, in this case, the webapp folder.

The Challenge: Serving from a Subdirectory

When dealing with a monorepo structure, it's common to have various shared assets or different applications under one repository. For instance, in our scenario, we have a webapp folder that contains the Node.js application, but AWS Elastic Beanstalk will typically look for the package.json file at the project's root level. This can be inconvenient when you want to deploy a specific service or application from within a subdirectory.

Here’s what happens:

Elastic Beanstalk searches for a package.json file in the root directory of your repository.

If it doesn't find it there, deployment fails.

So, how do we make Elastic Beanstalk serve our application from the webapp subdirectory? Let’s break down the solution.

The Solution: Using a Procfile

After exploring various forums and documentation, the solution is simple and effective: you need to create a Procfile. Here’s how to do it:

Step 1: Create a Procfile

Location: Place the Procfile in the root directory of your monorepo alongside other important files.

Content: Open your favorite text editor and create a new file named Procfile. Add the following line to it:

This command tells Elastic Beanstalk to navigate to the webapp directory and run the npm start command when the application is deployed.

Step 2: Basic Script Explanation

Procfile Directive: The web: preceding the command specifies that this is a web application process.

Directory Change (cd): The command changes the directory from the root to the webapp folder.

Run the Application: npm start initiates your Node.js application using the script defined in the package.json file located in the webapp folder.

Step 3: Deployment in Elastic Beanstalk

Prepare Your Application: Complete any necessary configurations such as environment variables, dependencies, etc., in your webapp folder’s package.json.

Deploy: Push your changes to your AWS Elastic Beanstalk environment either through the AWS Management Console or using the EB CLI.

Monitoring and Testing: Once the deployment is complete, you can monitor your application through the Elastic Beanstalk dashboard to ensure it is running smoothly.

Conclusion

By creating a Procfile in the root directory and directing Elastic Beanstalk to the specific subdirectory containing your Node.js application, you can effectively serve your application from a monorepo. This approach simplifies the deployment process ensuring a seamless environment setup.

Don’t forget to check the Elastic Beanstalk documentation and AWS forums for additional tips and resources to enhance your deployment strategy! Happy coding!
