Introduction

Amazon Web Services (AWS) Amplify Console provides a continuous deployment and hosting service for mobile and web applications. When working with Node.js applications, a crucial aspect is ensuring the correct Node.js version is utilized during the build and deployment processes. The Provision Step in AWS Amplify Console is where you can specify the Node.js version your application requires. This article provides a detailed walkthrough on how to change the Node.js version during the Provision Step in Amplify Console.

Understanding the Build Process

AWS Amplify builds your project through a sequence of steps—Provision, Build, Deploy, and Verify. The Provision Step is critical as it sets up the necessary environment to ensure your app builds correctly. This setup includes specifying the Node.js version, which is essential for compatibility with application dependencies and runtime.

Steps to Change Node Version in the Provision Step

Step 1: Access Amplify Console

1. Navigate to the AWS Amplify Console.
2. Select the app you want to modify.

Step 2: Modify the Build Settings

1. Within the app's dashboard, proceed to App Settings and then navigate to Build settings.
2. Here, you'll see the amplify.yml configuration file. This file dictates the build process, including the Node.js version.

Step 3: Edit the amplify.yml File

Your build specification (amplify.yml) will contain multiple sections corresponding to various steps in the build process. To change the Node.js version, modify the runtime-versions within the provision section.

Example amplify.yml:

• npm install
• npm run build
• '**/*'
• node_modules/**/*
• Compatibility: Ensure the Node.js version is compatible with all dependencies in your package.json file.
• Environment: Consider environment-specific configurations as different environments may require different Node.js versions.
• Testing: Thoroughly test your application after changing the Node.js version to ensure no breaking changes.
• Node.js Documentation: For detailed information on Node.js versions and features, visit the official Node.js documentation.
