Gongyuan worked on cross-framework component development for Tencent’s tdesign-react and tdesign-vue repositories, focusing on enhancing the Switch component with a beforeChange API. This addition enabled both synchronous and asynchronous validation before state changes, improving user experience and reliability by deferring toggles until validation completed. Gongyuan implemented this using JavaScript, TypeScript, and Vue, ensuring parity between React and Vue versions and supporting complex validation patterns. In addition, Gongyuan stabilized the NotificationPlugin in tdesign-react by fixing a rendering bug, ensuring notifications attach to the correct DOM container. The work demonstrated depth in API design, asynchronous programming, and front-end engineering.
