Developed and delivered a global dark mode feature for the redhat-cop/babylon repository, introducing an admin-gated toggle with persistent settings and robust theme tokening. The implementation included a centralized DarkModeProvider architecture in React, over 150 lines of CSS overrides for consistent readability across 17 UI components, and comprehensive automated testing with 55 passing tests. Upgraded the catalog UI to version 0.36.0, enabling new Operations page functionality and multi-asset hierarchy with bulk actions. Enhanced accessibility with improved aria-labels and beta tooltips, while updating documentation with dark mode screenshots. Work utilized JavaScript, TypeScript, and CSS for maintainable, user-focused theming.
March 2026: Delivered a robust global dark mode across Babylon with admin-only beta gating, persistence, and theme tokening. Implemented DarkModeProvider/useDarkMode architecture and 150+ lines of CSS overrides to maintain readability across 17 components (catalog, admin, ops, editor, incidents banner, etc.). Upgraded catalog-ui to v0.36.0, enabling the Operations page, multi-asset hierarchy with bulk actions, and overall dark mode polish; added beta tooltip and accessibility improvements. Documentation updated with dark mode screenshots across catalog, services, admin, and ops pages; test suite validated with 55 passing tests (44 Ops + 5 Header + 6 useDarkMode). Admin gating ensures only admins can toggle; non-admins auto-disable if access is revoked, preventing user lock-in. This release improves user experience, reduces support burden, and strengthens theming maintainability.
