Supported Node.js versions for the AWS CDK

The AWS Cloud Development Kit (AWS CDK) runs on Node.js. This includes the AWS CDK CLI (aws-cdk-cli), AWS Construct Library (aws-cdk-lib), as well as broader ecosystem tools such as JSII, Projen, and CDK8s.

Version support policy

The AWS CDK supports Node.js Long Term Support (LTS) versions. When a Node.js version reaches its community End-of-Life (EOL), the AWS CDK continues to support it for an additional 6 months before ending support.

After support ends, the AWS CDK team will no longer provide security patches, bug fixes, or compatibility updates for that Node.js version. Using the AWS CDK with an unsupported Node.js version may result in unexpected behavior, errors, or security vulnerabilities.

For upcoming Node.js release and EOL dates, see the Node.js release schedule.
