AWS Lambda adds support for Node.js 24

AWS Lambda now supports creating serverless applications using Node.js 24. Developers can use Node.js 24 as both a managed runtime and a container base image, and AWS will automatically apply updates to the managed runtime and base image as they become available.

Node.js 24 is the latest long-term support release of Node.js and is expected to be supported for security and bug fixes until April 2028. With this release, Lambda has simplified the developer experience, focusing on the modern async/await programming pattern and no longer supports callback-based function handlers. You can use Node.js 24 with Lambda@Edge (in supported Regions), allowing you to customize low-latency content delivered through Amazon CloudFront. Powertools for AWS Lambda (TypeScript), a developer toolkit to implement serverless best practices and increase developer velocity, also supports Node.js 24. You can use the full range of AWS deployment tools, including the Lambda console, AWS CLI, AWS Serverless Application Model (AWS SAM), AWS CDK, and AWS CloudFormation to deploy and manage serverless applications written in Node.js 24.

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