During March 2025, this developer focused on improving the reliability of the CmdbInstanceSelectPanel component in the easyops-cn/next-basics repository. They addressed a stability issue by implementing defensive rendering logic in React and TypeScript, ensuring the panel only renders when both objectId and objectMap are present. This targeted fix reduced the risk of runtime errors and improved the robustness of the user interface for those working with CMDB data. The change was low-risk, with a clear rollback path, and demonstrated careful attention to error prevention and code maintainability using front-end development best practices in JavaScript and TypeScript.
