During November 2025, Hanxi developed and delivered the SoundSpace Theme for the hanxi/xiaomusic repository, focusing on consistent theming across desktop and mobile platforms. Hanxi refactored build processes and animation logic to ensure seamless mobile compatibility, leveraging CSS, HTML, and JavaScript to enhance cross-device branding and user experience. The work included implementing Vite-based path aliases and base URL configuration, which streamlined development and improved build performance. Additionally, Hanxi resolved a bug affecting the SoundSpace random play mode, restoring reliable playback and stability. This work demonstrated a thoughtful approach to maintainability, mobile UX, and efficient front end development practices.
