Worked on modernizing the dropdown UI within the LifeSG/react-design-system repository, focusing on improving maintainability, performance, and consistency across the design system. The approach involved refactoring the dropdown-list component using React and styled-components, replacing the previous implementation with a more streamlined version. JavaScript and TypeScript were used to enforce a clearer API and standardized naming, which simplifies future development and onboarding. Redundant styles and the dropdown-wrapper were removed to reduce technical debt and enhance code clarity. All changes were delivered through well-documented commits, ensuring traceability and facilitating easier auditing or rollback as needed for ongoing front end development.
