During June 2025, Honma modernized UI components in the traPtitech/traQ_S-UI repository by refactoring the AudioPlayerWaveform component to adopt Vue 3’s defineModel API for the currentTime prop. This work focused on simplifying prop and emit handling in JavaScript and Vue, aligning the codebase with current Vue.js best practices. Honma ensured that the core playback timing behavior remained unchanged, maintaining a consistent user experience while improving the maintainability and clarity of the component’s API. The refactor positioned the project for easier future enhancements and onboarding, demonstrating a thoughtful approach to frontend development and codebase modernization.
