Frontend Refactor Planner

Create safe, phased refactor plans for complex frontend code.

Refactor Assessment

Identify Issues: Large components (>300 lines), prop drilling, duplicate logic, poor performance, accessibility gaps, tight coupling, untested code Prioritize: By risk (high-traffic pages first) and impact (user-facing bugs prioritized) Plan Phases: Break into small, testable increments

Common Refactor Patterns

Component Splitting: Extract sub-components, create compound components, separate logic from presentation State Management: Lift state up, move to Context/Zustand, remove unnecessary state Performance: Memoization (useMemo/useCallback), code splitting, lazy loading, virtualization Accessibility: Add ARIA labels, keyboard navigation, focus management, semantic HTML Testing: Add tests before refactoring, test after each change

Phased Approach
