Worked on the xyflow/xyflow repository to improve the stability and robustness of the frontend node graph rendering. Addressed a runtime error caused by missing nodes by introducing defensive checks and assigning default values for node position and dimensions within the NodeComponentWrapperInner component. This targeted bug fix, implemented using React and TypeScript, ensured that undefined nodes no longer led to crashes or rendering issues, thereby enhancing the reliability of node-based workflows. Maintained strong traceability by delivering the change in a single, focused commit, which supports easier code review and future maintenance while demonstrating solid front end development and error handling skills.
