During October 2025, Liuyangxing focused on stabilizing the Workflow Editor within the nndeploy/nndeploy repository by addressing a critical bug in its drag-and-drop functionality. He implemented a canDropToNode validation, using React and TypeScript, to prevent parent nodes from being dropped into their own children, thereby preserving the hierarchical integrity of nested subgraphs. This solution eliminated invalid drop states and reduced the risk of workflow corruption during design-time operations. Liuyangxing’s work demonstrated careful attention to front-end logic and workflow management, resulting in a more reliable user experience and reducing potential support issues related to complex graph editing scenarios.
