AWS Cloud Development Kit (CDK) will stop supporting Node.js 18.x on December 1, 2025, following its end of life on April 30, 2025. Users should upgrade to Node.js Active Long Term Support version 22.x to receive security patches and access new features. Dropping support for Node.js 18.x aligns with security best practices and ensures compatibility with modern APIs. Projects on Node.js 18.x will face a growing compatibility gap, limiting access to AWS CDK innovations. After December 1, 2025, issues related to Node.js 18.x will not be supported.
AWS Cloud Development Kit will end support for Node.js 18.x on December 1, 2025, following its end of life on April 30, 2025. Users are encouraged to upgrade to Node.js LTS versions to ensure access to security updates and new features.
By discontinuing support for Node.js 18.x, AWS CDK ensures users receive the latest security patches, performance improvements, and modern capabilities. This aligns with AWS's commitment to security best practices.
CDK projects on Node.js 18.x will miss out on new features developed with modern Node.js APIs. This compatibility gap will increasingly impede access to AWS CDK innovations.
Any issues with Node.js 18.x will not receive support after December 1, 2025. Support requests require reproduction on supported Node.js versions.
