Worked on the HuLaSpark/HuLa repository to enhance group chat functionality by implementing group messaging with accurate handling of group chat IDs and types within openMsgSession. Leveraged TypeScript and Vue.js to update API integrations and data models, enabling robust group interactions and introducing group list pagination for scalable management. Addressed UI stability by refining view and component layers, improving typing indicators, and rolling back problematic input handling. Added cursor position save and restore to improve the message composition experience. Maintained codebase alignment by merging main branch changes, demonstrating a focus on frontend development, state management, and collaborative feature delivery.
