AWS Lambda adds support for Node.js 24

AWS Lambda Node.js 24 Support

AWS Lambda now supports Node.js 24 for creating serverless applications. This includes both a managed runtime and a container base image, with automatic updates as they become available. Node.js 24 is the latest long-term support release, expected to be supported until April 2028.

Lambda has simplified the developer experience by focusing on the modern async/await programming pattern and no longer supports callback-based function handlers. Node.js 24 is also available with Lambda@Edge in supported Regions, allowing for low-latency content customization through Amazon CloudFront.

Powertools for AWS Lambda (TypeScript) now supports Node.js 24, enabling developers to implement serverless best practices and increase velocity. You can deploy and manage serverless applications using Node.js 24 with the Lambda console, AWS CLI, AWS SAM, AWS CDK, and AWS CloudFormation.

The Node.js 24 runtime is available in all Regions, including AWS GovCloud (US) and China Regions.

What to do

• Upgrade existing Lambda functions to Node.js 24.
• Use async/await programming pattern.
• Leverage Powertools for AWS Lambda (TypeScript) for best practices.
