Worked on the ant-design/x repository to enhance performance and reliability of SSE streaming within the ChatMessagesStore component. Focused on front end development using React and TypeScript, the developer implemented a 50ms throttle to reduce excessive React re-renders during server-sent events, addressing issues like 'Maximum update depth exceeded.' They introduced a destroy method for explicit resource cleanup and ensured that throttle timers are automatically cleared when all listeners unsubscribe, preventing memory leaks and setState warnings. The solution maintained compatibility for multiple components sharing the store via conversationKey, and included thorough documentation to support maintainers and future performance reviews.
