Worked on enhancing the live demo experience in the ant-design/x repository by introducing a LiveError feedback mechanism within the CodePreviewer component. This feature provided immediate error visibility during code execution, improving the responsiveness and usability of the documentation’s live demos. Addressed module resolution issues in the documentation tooling, which stabilized the demo pipeline and reduced inconsistencies for both end users and contributors. Coordinated updates to ensure compatibility with Dumi-based documentation, aligning the user interface for a smoother workflow. Utilized React for front end development and implemented changes in both JavaScript and TypeScript, focusing on reliability and user-centric design improvements.
