Worked on the easyops-cn/next-basics repository to enhance the Dynamic Form Item module, focusing on both feature development and bug resolution. Delivered improvements to import data filtering and expanded export support for arrays, multi-value fields, and Cascader components, resulting in more robust and flexible form workflows. Addressed a type issue by refining the importFilter field from an array of strings to a single string, streamlining integration and usability. Leveraged React and TypeScript to implement these changes, while also updating and expanding automated test coverage to ensure reliability and reduce edge-case errors in dynamic form export and import processes.
