Worked on the ant-design/md-editor repository to enhance the stability and maintainability of the Markdown Editor, focusing on front-end development with TypeScript. Addressed a bug where configuration comments for chart nodes were generated incorrectly, ensuring comments are only created when a valid configuration exists. Improved the handling of node configurations by distinguishing between chart nodes and other node types, which now use config.config and configProps respectively, resulting in more accurate JSON serialization. Refactored serialization logic into a local variable to improve code readability. These targeted changes reduced code churn and established a more reliable foundation for future feature development.
