Developed and delivered a Local Folder Access and File Management UI for the doocs/md repository, enabling users to interact directly with their local file systems without relying on uploads or server storage. The solution involved building Vue.js components and TypeScript modules to support end-to-end local file reading, writing, and folder selection, all integrated into the existing editor workflow. State management was implemented to ensure stable, resizable layouts and robust folder access. By introducing a dynamic file tree and seamless UI enhancements, the work reduced latency and data transfer, empowering users with faster, offline-capable editing and greater autonomy in file operations.
