Implementation Timeline + +### Week 1: Migration + Schema +- [ ] Implement new RxDB schemas (events v0, calendars v0) +- [ ] Write migration script (v1 → v0) +- [ ] Create migration UI dialog +- [ ] Test migration with sample data +- [ ] Add rollback mechanism + +### Week 2: Event Fetching + State +- [ ] Reimplement event fetching with indexes +- [ ] Create `useCalendarEvents` hook with date range queries +- [ ] Create query hooks for different views +- [ ] Set up Zustand store for UI state +- [ ] Add error boundaries +- [ ] Write unit tests for hooks + +### Week 3: Calendar Utilities +- [ ] Implement RRULE-based recurrence with `rrule` library +- [ ] Implement timezone support with `date-fns-tz` +- [ ] Write calendar utility functions +- [ ] Write comprehensive unit tests (100% coverage) +- [ ] Test edge cases (DST, leap years, etc.) + +### Week 4: UI Components +- [ ] Rebuild WeekView with new event fetching +- [ ] Rebuild MonthView with new event fetching +- [ ] Build AgendaView +- [ ] Build DayView +- [ ] Rebuild EventDialog with better recurrence UI +- [ ] Add loading states and error states + +### Week 5: Testing +- [ ] Set up Vitest for unit tests +- [ ] Write unit tests for all utilities (target 90%+) +- [ ] Set up Playwright for E2E tests +- [ ] Write E2E test scenarios (10+ tests) +- [ ] Write visual regression tests +- [ ] Write performance tests +- [ ] Set up CI to run all tests + +### Week 6-7: Features +- [ ] Implement multiple calendars +- [ ] Implement event search +- [ ] Implement drag-and-drop with `@dnd-kit` +- [ ] Implement reminders with notifications +- [ ] Implement timezone selector in event form +- [ ] Update iCalendar export with new fields +- [ ] Implement iCalendar import +- [ ] Implement calendar subscriptions +- [ ] Implement keyboard navigation + +### Week 8: Polish +- [ ] UI/UX improvements +- [ ] Mobile optimizations +- [ ] Accessibility improvements (ARIA, keyboard nav) +- [ ] Performance optimizations +- [ ] Empty states +- [ ] Loading states +- [ ] Documentation + +--- + +## Success Metrics + +### Performance +- [ ] Initial load < 2s +- [ ] Event rendering < 100ms for 100 events in view +- [ ] Query time < 50ms with 1000 total events +- [ ] Smooth scrolling (60 FPS) +- [ ] Bundle size < 500KB (gzipped) + +### Reliability +- [ ] Zero data loss during migration +- [ ] Migration success rate > 99% +- [ ] < 1% error rate in production +- [ ] Offline mode works 100% of time + +### Testing +- [ ] 90%+ unit test coverage +- [ ] 100% critical path E2E coverage +- [ ] All UI components have visual regression tests + +### Feature Parity +- [ ] Match Google Calendar core features +- [ ] iCalendar import/export works with all major vendors +- [ ] Calendar subscriptions work with public calendars + +--- + +## Dependencies + +### New Dependencies +- `rrule` - Recurrence rule parsing/generation (standard library, 2.7M weekly downloads) +- `date-fns-tz` - Timezone support +- `@dnd-kit/core` - Drag and drop +- `react-virtuoso` - Virtualization for performance +- `ical.js` - iCalendar parsing +- `zustand` - State management +- `vitest` - Unit testing +- `@testing-library/react` - Component testing +- `@playwright/test` - E2E testing + +### Existing Dependencies (Keep) +- `rxdb` - Database +- `date-fns` - Date manipulation +- `react-hook-form` + `zod` - Form handling +- `shadcn/ui` - UI components + +--- + +## What We're NOT Changing + +1. **Timetable code** - Zero changes to timetable components or logic +2. **Timetable→Calendar sync** - Existing sync mechanism stays as-is +3. **`timetablesync` collection** - Schema unchanged +4. **Backend timetable APIs** - No changes +5. **Course data** - No changes + +**The only integration point:** Calendar will continue to accept events from timetable sync, but that's handled by existing code. + +--- + +## Risk Assessment + +### High Risk + +**Risk:** Data loss during migration +- **Mitigation:** Automatic backup before migration, validation after, rollback option +- **Testing:** Test migration with 100+ different event patterns + +**Risk:** Performance degradation with many events +- **Mitigation:** Proper indexes, date range queries, virtualization, performance tests +- **Testing:** Load test with 1000+ events + +### Medium Risk + +**Risk:** Timezone bugs +- **Mitigation:** Use well-tested `date-fns-tz`, comprehensive timezone tests, DST edge cases +- **Testing:** Test with multiple timezones, DST transitions + +**Risk:** RRULE compatibility +- **Mitigation:** Use standard `rrule` library, test with real iCalendar files from Google/Apple/Outlook +- **Testing:** Import/export round-trip tests + +### Low Risk + +**Risk:** Migration UI confusing +- **Mitigation:** Clear messaging, progress bar, migration report +- **Testing:** User testing before release + +--- + +## Conclusion + +This plan provides a focused path to reimplement the calendar with: + +1. ✅ **Clean Architecture** - Proper schemas, indexes, and efficient queries +2. ✅ **Data Migration** - Safe migration from old calendar to new with backup/rollback +3. ✅ **Better Event Fetching** - Indexed queries, date range filtering, proper recurrence handling +4. ✅ **Comprehensive Testing** - Unit, integration, and E2E tests with 90%+ coverage +5. ✅ **Feature Parity** - Match major calendar vendors +6. ✅ **No Timetable Changes** - Calendar is independent, timetable untouched + +**Timeline:** 8 weeks for full implementation + +**Next Steps:** +1. Review and approve this plan +2. Confirm migration strategy +3. Begin Week 1 implementation +4.
