AWS Lambda now supports Node.js 18 as a managed runtime in the AWS GovCloud (US) Regions. Developers creating serverless applications in Lambda with Node.js 18 in the AWS GovCloud regions can take advantage of new features such as an upgrade of the bundled AWS SDK for JavaScript to v3 and improved support for deploying ES Modules using Lambda layers. This release also provides access to Node.js 18 language enhancements, including the experimental ‘fetch’ API.
