Worked on the rolldown/rolldown repository to improve the accuracy and reliability of project setup documentation. Addressed a discrepancy between the documented and actual minimum Node.js version required for setup by implementing a data-driven solution using JavaScript and TypeScript. Introduced a mechanism that dynamically reads the minimum Node.js version from the .node-version file, ensuring that documentation always reflects the true runtime requirements. This approach streamlined onboarding for new users and reduced support overhead by minimizing confusion around environment prerequisites. The work focused on build tools and documentation, emphasizing traceability and maintainability through clear commit history and automated version alignment.
