Worked on the Sysvale/cuida repository to enhance UI reliability by addressing a bug affecting spinner visibility in the CdsButton component when secondary or ghost props were active. The solution involved refactoring the component to use the Vue Composition API, improving maintainability and setting a foundation for future enhancements. JavaScript and Vue were used to implement the fix, update related tests, and ensure documentation reflected the changes. Quality practices included passing ESLint checks and maintaining comprehensive test coverage. This work improved user experience by ensuring consistent loading state feedback and contributed to the overall stability of the front end codebase.
