Worked on the traPtitech/traQ_S-UI repository to enhance the stability of stamp interactions within archived channels. Addressed a specific bug by implementing component-level archiving checks using Vue.js and TypeScript, ensuring that stamp add or remove actions are blocked in archived channels. Provided clear UI feedback through toast notifications and improved error messaging to inform users when actions are restricted. Focused on state management to prevent inconsistent UI states and flickering during user interactions. Additionally, performed minor formatting cleanups to improve code readability and maintainability. The work emphasized robust front-end development practices and careful attention to user experience details.
