During January 2025, Tianya worked on the HuLaSpark/HuLa repository, focusing on enhancing group chat functionality for large-scale collaboration. They implemented group chat messaging by updating API integrations and data models to correctly handle group chat IDs and types, enabling robust group interactions. Using TypeScript and Vue.js, Tianya introduced group list pagination to support scalable group management and improved the messaging UI by addressing issues across view, hook, and component layers. They also enhanced the user experience by implementing cursor position save and restore during message composition, and maintained codebase stability through careful branch synchronization and targeted rollbacks where necessary.
