Worked on modernizing the dhis2/maps-app repository by upgrading its development stack to Vite and React 18, replacing legacy Webpack configurations and migrating source files to JSX. This transition streamlined the build process, resulting in faster development cycles and a more maintainable codebase. The update included introducing a new development script for ee_worker and aligning testing configurations with the latest tooling standards. By leveraging JavaScript, React, and CI/CD practices, the work established a robust foundation for future feature development, enabling smoother integration of user-facing enhancements and ensuring the project remains compatible with contemporary web development workflows and best practices.
