Worked on modernizing 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 update streamlined prop and emit handling, aligning the codebase with current Vue.js best practices while maintaining consistent playback timing behavior for users. The approach focused on simplifying the component API, making the codebase more maintainable and easier to enhance in the future. Leveraged frontend development skills with JavaScript and Vue to ensure the refactor preserved all core functionality, supporting smoother onboarding and future development within the project’s evolving architecture.
