Worked on the tailscale/github-action repository to deliver an XDG Base Directory compliant storage update, focusing on improving file system organization and compatibility for Linux environments. The update relocated the storage of tailscale.tgz and tailscaled.pid from the working directory to XDG cache and runtime directories, aligning with established Linux filesystem conventions. This approach reduced workspace clutter and enhanced the reliability of continuous integration workflows by standardizing artifact locations. The work involved cross-platform development and file system management using JavaScript and Node.js, ensuring that the solution integrated smoothly with existing developer workflows and improved environment compatibility without introducing breaking changes.
