Worked on the Mastodon repository to address a build failure related to Vite when running on Node.js v20. The solution involved correcting how entrypoint file paths for JavaScript and SCSS were resolved by replacing the use of file.parentPath with explicit directory paths. This adjustment improved the reliability of the continuous integration process and ensured stable cross-environment builds. The work focused on build tools and configuration, leveraging skills in Node.js, Vite, JavaScript, and TypeScript. By enhancing build-system debugging and entrypoint management, the changes reduced the risk of future path-resolution issues and contributed to more maintainable release workflows.
