Winay contributed to the mermaid-js/mermaid repository by developing per-edge curve styling for Flowcharts, enabling users to specify custom curve types for individual links. He refactored the flowDB.ts module to support a new curve parameter, updating the interpolation logic to integrate with d3-shape curves and the latest configuration syntax. His work included comprehensive unit and visual tests to ensure stability, as well as documentation updates that clarified usage and removed deprecated directive syntax. Using JavaScript and TypeScript, Winay focused on enhancing diagram expressiveness and maintainability, delivering two features that improved both user flexibility and the developer experience.
