Worked on stabilizing the Preview feature’s file watching mechanism in the increments/qiita-cli repository, focusing on improving reliability and performance. Addressed EMFILE errors by refining the watched paths and excluding unnecessary directories, which reduced runtime issues and enhanced the end-user experience. Enhanced the public API by exposing the FileSystemRepo.getRootPath() method, enabling better integration with external tooling. Updated the preview command to align with the repository root path and implemented ignore patterns to prevent monitoring of irrelevant directories. Utilized Node.js, TypeScript, and full stack development skills to deliver a more robust and scalable file-watching foundation for future enhancements.
