  • Extract EventRow.tsx
  • Extract CategorySection.tsx
  • Extract CalendarView.tsx
  • Create hooks/useEventsData.ts
  • Create hooks/useEventsActions.ts
  • Refactor main EventsPage.tsx

3.2 Implement Container/Presenter Pattern

  • Identify container components
  • Extract presenter components
  • Create custom hooks for business logic
  • Update existing pages to use pattern

Phase 4: Configuration & Theming

  • Regular check-ins on progress

Timeline Risks

  • Prioritize high-impact changes first
  • Break work into small, manageable chunks
  • Regular progress reviews
  • Adjust timeline based on velocity

Progress Tracking

Daily

  • Update checklist items
  • Track lines of code changed
  • Monitor test coverage

Weekly

  • Review progress against timeline
  • Adjust priorities as needed
  • Share updates with team

Monthly

Notes & Decisions

Key Decisions Needed:

  1. State management library choice (Zustand vs Context + useReducer)
  2. Testing framework configuration
  3. Performance monitoring tools
  4. Documentation platform

Assumptions:

  • Team size: 2-3 developers
  • Development velocity: Medium
  • Priority: Maintainability over new features
  • Budget: Available for tooling if needed

Constraints:

  • Must maintain existing functionality
  • Limited disruption to users
  • Gradual rollout preferred
  • Backward compatibility important
