<!-- OPENSPEC:START -->
# OpenSpec Instructions
These instructions are for AI assistants working in this project.
Always open `@/openspec/AGENTS.md` when the request:
- Mentions planning or proposals (words like proposal, spec, change, plan)
- Introduces new capabilities, breaking changes, architecture shifts, or big performance/security work
- Sounds ambiguous and you need the authoritative spec before coding
Use `@/openspec/AGENTS.md` to learn:
- How to create and apply change proposals
- Spec format and conventions
- Project structure and guidelines
Keep this managed block so 'openspec update' can refresh the instructions.
<!-- OPENSPEC:END -->
# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project Overview
La Suite Calendars is a modern calendar application for managing events and schedules. It's a full-stack application with:
- **Backend**: Django 5 REST API with PostgreSQL
- **Frontend**: Next.js 15 with React 19
- **CalDAV Server**: SabreDAV (PHP-based) for calendar protocol support : https://sabre.io/dav/
- **Authentication**: Keycloak OIDC provider
In this project, you can create events, invite people to events, create calendars, and invite others to share and manage those calendars, allowing them to add and manage events as well. Every invitation sends an email with an ICS file attached; this also happens for event updates and cancellations.
## Common Commands
### Development Setup
```bash
make bootstrap # Initial setup: builds containers, runs migrations, starts services
make run # Start all services (backend + frontend containers)
make run-backend # Start backend services only (for local frontend development)
make stop # Stop all containers
make down # Stop and remove containers, networks, volumes
```
### Backend Development
```bash
make test-back -- path/to/test.py::TestClass::test_method # Run specific test
make test-back-parallel # Run all tests in parallel
make lint # Run ruff + pylint
make migrate # Run Django migrations
make makemigrations # Create new migrations
make shell # Django shell
make dbshell # PostgreSQL shell
```
### Frontend Development
```bash
make frontend-development-install # Install frontend dependencies locally
make run-frontend-development # Run frontend locally (after run-backend)
make frontend-lint # Run ESLint on frontend
cd src/frontend/apps/calendars && yarn test # Run frontend tests
cd src/frontend/apps/calendars && yarn test:watch # Watch mode
```
### E2E Tests
```bash
make run-tests-e2e # Run all e2e tests
make run-tests-e2e -- --project chromium --headed # Run with specific browser
```
### Internationalization
```bash
make i18n-generate # Generate translation files
make i18n-compile # Compile translations
make crowdin-upload # Upload sources to Crowdin
make crowdin-download # Download translations from Crowdin
```
## Architecture
### Backend Structure (`src/backend/`)
- `calendars/` - Django project configuration, settings, Celery app
- `core/` - Main application code:
- `api/` - DRF viewsets and serializers
- `models.py` - Database models
- `services/` - Business logic
- `authentication/` - OIDC authentication
- `tests/` - pytest test files
### Frontend Structure (`src/frontend/`)
Yarn workspaces monorepo:
- `apps/calendars/` - Main Next.js application
- `src/features/` - Feature modules (calendar, auth, api, i18n, etc.)
- `src/pages/` - Next.js pages
- `src/hooks/` - Custom React hooks
- `apps/e2e/` - Playwright end-to-end tests
### CalDAV Server (`docker/sabredav/`)
PHP SabreDAV server providing CalDAV protocol support, running against the shared PostgreSQL database.
### Service Ports (Development)
- Frontend: http://localhost:8920
- Backend API: http://localhost:8921
- CalDAV: http://localhost:8922
- Keycloak: http://localhost:8925
- PostgreSQL: 8912
- Mailcatcher: http://localhost:1081
## Key Technologies
### Backend
- Django 5 with Django REST Framework
- Celery with Redis for background tasks
- pytest for testing (use `bin/pytest` wrapper)
- Ruff for linting/formatting (100 char line length for pylint compatibility)
### Frontend
- Next.js 15 with React 19
- @tanstack/react-query for data fetching
- tsdav/ical.js/tsics for CalDAV client integration : https://tsdav.vercel.app/docs/intro / https://github.com/Neuvernetzung/ts-ics
- @gouvfr-lasuite/cunningham-react for UI components : https://github.com/suitenumerique/cunningham
- Jest for unit tests
- Playwright for e2e tests
## Code Style
### Python
- Follow PEP 8 with 100 character line limit
- Use Django REST Framework viewsets for APIs
- Business logic in models and services, keep views thin
- Use `select_related`/`prefetch_related` for query optimization
### TypeScript/React
- Feature-based folder structure under `src/features/`
- Use React Query for server state management as possible, if it is not possible, don't worry.
- Use the vercel-react-best-practices skill when you write a react code
- Please, make many tiny files and separate components in differentes files
- Check for Lint and TypeScript errors before telling me that you have finished
### Git
- Maximum line length: 80 characters.
- Each commit must have a title and a description.
- The commit title should start with a Gitmoji, then the area in parentheses
(e.g. back, front, docs), then your chosen title.
# Workflow
- Be sure to typecheck when you're done making a series of code changes
- Prefer running single tests, and not the whole test suite, for performance

└── RECURRENCE_EXAMPLES.md # Usage examples
```
## 🔧 Integration Steps
### Step 1: Use the Component
The component is already created! Just import and use it:
```tsx
import { RecurrenceEditor } from '@/features/calendar/components/RecurrenceEditor';
import type { IcsRecurrenceRule } from 'ts-ics';
const [recurrence, setRecurrence] = useState<IcsRecurrenceRule | undefined>();
<RecurrenceEditor value={recurrence} onChange={setRecurrence} />
```
### Step 2: Include in IcsEvent
```tsx
const event: IcsEvent = {
uid: crypto.randomUUID(),
summary: "Team Meeting",
start: { date: new Date() },
end: { date: new Date() },
recurrenceRule: recurrence, // ← Add this
};
```
### Step 3: That's It!
CalDAV handles everything else:
- ✅ Stores RRULE in .ics file
- ✅ Expands recurring instances
- ✅ Syncs with other calendar apps
## 🎨 UI Preview
### Simple Mode
```
┌────────────────────────────┐
│ Repeat: [Daily ▼] │
└────────────────────────────┘
```
### Custom Mode - Weekly
```
┌─────────────────────────────────────────┐
│ Repeat every [2] [weeks ▼] │
│ │
│ Repeat on: │
│ [M] [T] [W] [T] [F] [S] [S] │
│ ✓ ✓ │
│ │
│ Ends: │
│ ○ Never │
│ ○ On [2025-12-31] │
│ ⦿ After [10] occurrences │
└─────────────────────────────────────────┘
```
### Custom Mode - Monthly with Warning
```
┌─────────────────────────────────────────┐
│ Repeat every [1] [months ▼] │
│ │
│ Repeat on day: │
│ Day [30] │
│ │
│ ⚠️ This month has at most 30 days │
└─────────────────────────────────────────┘
```
## 🌍 Internationalization
Fully translated in:
- 🇬🇧 English
- 🇫🇷 French
- 🇳🇱 Dutch
All UI strings, month names, and warning messages.
## 🧪 Testing
Run the test suite:
```bash
npm test RecurrenceEditor
```
Test coverage:
- ✅ Component rendering
- ✅ User interactions
- ✅ All frequency types
- ✅ Date validation
- ✅ End conditions
- ✅ Edge cases
## 📖 Common Use Cases
### 1. Daily Standup (Every Weekday)
```typescript
{
frequency: 'WEEKLY',
byDay: [
{ day: 'MO' },
{ day: 'TU' },
{ day: 'WE' },
{ day: 'TH' },
{ day: 'FR' }
]
}
```
**RRULE:** `FREQ=WEEKLY;BYDAY=MO,TU,WE,TH,FR`
### 2. Bi-Weekly Sprint Planning
```typescript
{
frequency: 'WEEKLY',
interval: 2,
byDay: [{ day: 'MO' }],
count: 10
}
```
**RRULE:** `FREQ=WEEKLY;INTERVAL=2;BYDAY=MO;COUNT=10`
### 3. Monthly Team Meeting (15th)
```typescript
{
frequency: 'MONTHLY',
byMonthDay: [15]
}
```
**RRULE:** `FREQ=MONTHLY;BYMONTHDAY=15`
### 4. Annual Birthday
```typescript
{
frequency: 'YEARLY',
byMonth: [3],
byMonthDay: [15]
}
```
**RRULE:** `FREQ=YEARLY;BYMONTH=3;BYMONTHDAY=15`
See [RECURRENCE_EXAMPLES.md](./RECURRENCE_EXAMPLES.md) for 10+ detailed examples!
## 🔍 Architecture
```
┌──────────────────────────────────────────────────┐
│ RecurrenceEditor Component (React) │

└──────────────────────────────────────────────────┘
```
**No backend changes needed!** Everything is handled by CalDAV standard.
## 🎯 Next Steps
### To Use in Your App
1. Read [SCHEDULER_RECURRENCE_INTEGRATION.md](./SCHEDULER_RECURRENCE_INTEGRATION.md)
2. Follow the 5-step integration guide
3. Test with your event modal
### To Learn More
1. Browse [RECURRENCE_EXAMPLES.md](./RECURRENCE_EXAMPLES.md) for real-world scenarios
2. Check [RECURRENCE_IMPLEMENTATION.md](./RECURRENCE_IMPLEMENTATION.md) for deep dive
3. Review [RECURRENCE_SUMMARY.md](./RECURRENCE_SUMMARY.md) for quick reference
## ❓ FAQ
### Q: Does this work with existing CalDAV events?
**A:** Yes! The component uses standard RRULE format compatible with all CalDAV clients (Apple Calendar, Google Calendar, Outlook, etc.).
### Q: Can users edit existing recurring events?
**A:** Yes! The component loads existing recurrence rules from events and allows editing the entire series.
### Q: What about editing single instances?
**A:** Not yet implemented in UI. CalDAV supports it via RECURRENCE-ID, but the UI for "Edit this occurrence" vs "Edit series" is a future enhancement.
### Q: Do recurring events sync with other calendar apps?
**A:** Yes! All patterns are standard RFC 5545 RRULE format.
### Q: Can I create "First Monday of month" patterns?
**A:** Not yet. That requires BYSETPOS which is a future enhancement.
### Q: What happens with February 30th?
**A:** The UI shows a warning, and CalDAV will skip occurrences on invalid dates.
## 🐛 Troubleshooting
### Events not appearing as recurring
1. Check browser console for errors
2. Verify `recurrenceRule` is in IcsEvent object
3. Check CalDAV server supports RRULE
4. Inspect .ics file in network tab
### Translations not showing
1. Verify translations.json includes new keys
2. Check i18n is initialized
3. Reload page after adding translations
### Styles not applying
1. Ensure RecurrenceEditor.scss is imported in globals.scss
2. Check for CSS conflicts
3. Verify BEM class names
See [RECURRENCE_IMPLEMENTATION.md](./RECURRENCE_IMPLEMENTATION.md#troubleshooting) for more help.

## 📅 Example 3: Monthly All-Hands Meeting
**Requirement:** First Monday of each month at 2:00 PM
⚠️ **Note:** "First Monday" pattern requires BYSETPOS (not yet implemented).
**Workaround:** Use specific date if consistent, or create manually each month.
**Alternative - Specific Day of Month:**
### Configuration
```typescript
const recurrence: IcsRecurrenceRule = {
frequency: 'MONTHLY',
interval: 1,
byMonthDay: [5] // 5th of every month
};
```
### UI Steps
1. Select "Custom..."
2. Choose "months" frequency
3. Enter "5" for day of month
4. Select "Never"
### Generated RRULE
```
RRULE:FREQ=MONTHLY;BYMONTHDAY=5
```
---
## 📅 Example 4: Quarterly Business Review
**Requirement:** Last day of March, June, September, December at 3:00 PM
⚠️ **Current Implementation:** Set up as 4 separate yearly events.
**Future Implementation:** Would use BYMONTH with multiple months.
### Configuration (Workaround)
Create 4 separate yearly events:
**Q1 (March 31):**
```typescript
{
frequency: 'YEARLY',
interval: 1,
byMonth: [3],
byMonthDay: [31]
}
```
**Q2 (June 30):**
```typescript
{
frequency: 'YEARLY',
interval: 1,
byMonth: [6],
byMonthDay: [30]
}
```
**Q3 (September 30):**
```typescript
{
frequency: 'YEARLY',
interval: 1,
byMonth: [9],
byMonthDay: [30]
}
```
**Q4 (December 31):**
```typescript
{
frequency: 'YEARLY',
interval: 1,
byMonth: [12],
byMonthDay: [31]
}
```

4. Enter "15" for day
5. Select "Never"
### Generated RRULE
```
RRULE:FREQ=YEARLY;BYMONTH=3;BYMONTHDAY=15
```
---
## 📅 Example 6: Payroll Processing
**Requirement:** 1st and 15th of every month
⚠️ **Current Implementation:** Create as 2 separate events:
**First event (1st):**
```typescript
{
frequency: 'MONTHLY',
interval: 1,
byMonthDay: [1]
}
```
**Second event (15th):**
```typescript
{
frequency: 'MONTHLY',
interval: 1,
byMonthDay: [15]
}
```
### UI Steps (for each)
1. Select "Custom..."
2. Choose "months"
3. Enter day (1 or 15)
4. Select "Never"
---
## 📅 Example 7: Project Deadline (Fixed End Date)
**Requirement:** Daily check-ins until project ends on December 31, 2025
### Configuration
```typescript
const recurrence: IcsRecurrenceRule = {
frequency: 'DAILY',

## 📅 Example 8: Gym Schedule (Mon/Wed/Fri)
**Requirement:** Gym sessions 3 times per week
### Configuration
```typescript
const recurrence: IcsRecurrenceRule = {
frequency: 'WEEKLY',
interval: 1,
byDay: [
{ day: 'MO' },
{ day: 'WE' },
{ day: 'FR' }
]
};
```
### UI Steps
1. Select "Custom..."
2. Choose "weeks"
3. Click M, W, F buttons
4. Select "Never"
### Generated RRULE
```
RRULE:FREQ=WEEKLY;BYDAY=MO,WE,FR
```
---
## 📅 Example 9: Leap Year Celebration
**Requirement:** February 29th celebration (only on leap years)
### Configuration
```typescript
const recurrence: IcsRecurrenceRule = {
frequency: 'YEARLY',
interval: 1,
byMonth: [2],
byMonthDay: [29]
};
```
### UI Steps
1. Select "Custom..."
2. Choose "years"
3. Select "February"
4. Enter "29"
5. ⚠️ Warning appears: "This date (Feb 29) only exists in leap years"
6. Select "Never"
### Generated RRULE
```
RRULE:FREQ=YEARLY;BYMONTH=2;BYMONTHDAY=29
```
### Occurrences
- Feb 29, 2024 ✅
- Feb 29, 2028 ✅
- Feb 29, 2032 ✅
- (Skips 2025, 2026, 2027, 2029, 2030, 2031)
---
## 📅 Example 10: Seasonal Team Offsite
**Requirement:** First day of each season (March, June, September, December)
Create 4 separate yearly events or use the pattern:
### Configuration (One event, workaround)
**For March 1:**
```typescript
{
frequency: 'YEARLY',
byMonth: [3],
byMonthDay: [1]
}
```
Repeat for months 6, 9, 12 as separate events.
**Better approach when BYMONTH allows multiple values:**
```typescript
// Future implementation
{
frequency: 'YEARLY',
byMonth: [3, 6, 9, 12], // Not yet supported in UI
byMonthDay: [1]
}
```
---
## 🎯 Complex Patterns Comparison
| Pattern | Status | Implementation |
|---------|--------|----------------|
| "Every day" | ✅ Supported | `FREQ=DAILY` |
| "Every weekday" | ✅ Supported | `FREQ=WEEKLY;BYDAY=MO,TU,WE,TH,FR` |
| "Every Monday" | ✅ Supported | `FREQ=WEEKLY;BYDAY=MO` |
| "1st of every month" | ✅ Supported | `FREQ=MONTHLY;BYMONTHDAY=1` |
| "Last day of month" | ✅ Supported (with caveat) | `FREQ=MONTHLY;BYMONTHDAY=31` |
| "1st Monday of month" | ❌ Future | Needs BYDAY + BYSETPOS |
| "Last Friday of month" | ❌ Future | Needs BYDAY + BYSETPOS=-1 |
| "Every 2 hours" | ❌ Not applicable | Events, not intraday recurrence |
---
## 🧪 Testing Patterns
### Test Case 1: Edge Case - February 30th
```typescript
// User selects:
{
frequency: 'YEARLY',
byMonth: [2],
byMonthDay: [30]
}
```
**Expected:** ⚠️ Warning: "February has at most 29 days"
**Behavior:** Event will never occur (no year has Feb 30)
### Test Case 2: Month Overflow - April 31st
```typescript
// User selects:
{
frequency: 'MONTHLY',
byMonthDay: [31]
}
```
**Occurrences:**
- January 31 ✅
- February 31 ❌ (skipped)
- March 31 ✅
- April 31 ❌ (skipped - only 30 days)
- May 31 ✅
- June 31 ❌ (skipped - only 30 days)
- July 31 ✅
**Warning shown for months with 30 days when setting up yearly recurrence**
---
## 📋 Quick Reference
### Frequency Types
```typescript
frequency: 'DAILY' // Every day
frequency: 'WEEKLY' // Every week (specify days)
frequency: 'MONTHLY' // Every month (specify day 1-31)
frequency: 'YEARLY' // Every year (specify month + day)
```
### Intervals
```typescript
interval: 1 // Every [frequency]
interval: 2 // Every 2 [frequency]
interval: 3 // Every 3 [frequency]
// etc.
```
### Days of Week (WEEKLY)
```typescript
byDay: [
{ day: 'MO' }, // Monday
{ day: 'TU' }, // Tuesday
{ day: 'WE' }, // Wednesday
{ day: 'TH' }, // Thursday
{ day: 'FR' }, // Friday
{ day: 'SA' }, // Saturday
{ day: 'SU' } // Sunday
]
```
### Day of Month (MONTHLY, YEARLY)
```typescript
byMonthDay: [15] // 15th of month
byMonthDay: [1] // 1st of month
byMonthDay: [31] // 31st of month (with caveats)
```
### Month (YEARLY)
```typescript
byMonth: [1] // January
byMonth: [2] // February
// ...
byMonth: [12] // December
```
### End Conditions
```typescript
// Never ends
(no count or until)
// Ends on date
until: {
type: 'DATE',
date: new Date('2025-12-31')
}
// Ends after N occurrences
count: 10
```

## 💡 Tips & Best Practices
### 1. Use Simple Mode for Common Patterns
Simple mode is sufficient for:
- Daily recurrence (every day)
- Weekly recurrence (every week, same days)
- Monthly recurrence (same date each month)
- Yearly recurrence (same date each year)
### 2. Use Custom Mode for Advanced Patterns
Custom mode is needed for:
- Intervals > 1 (every 2 weeks, every 3 months)
- Multiple days per week
- End dates or occurrence counts
- Specific validation
### 3. Date Validation
Always check for warnings when selecting:
- February dates (29, 30, 31)
- Month-end dates for monthly recurrence
- Day 31 for months with 30 days
### 4. CalDAV Compatibility
All patterns generated by RecurrenceEditor are standard RRULE format compatible with:
- Apple Calendar
- Google Calendar
- Microsoft Outlook
- Mozilla Thunderbird
- Any RFC 5545 compliant calendar

## Component Structure
### RecurrenceEditor Component
Location: `src/features/calendar/components/RecurrenceEditor.tsx`
**Props:**
```typescript
interface RecurrenceEditorProps {
value?: IcsRecurrenceRule;
onChange: (rule: IcsRecurrenceRule | undefined) => void;
}
```
**Features:**
- ✅ Simple mode: Quick selection (None, Daily, Weekly, Monthly, Yearly)
- ✅ Custom mode: Full control over all recurrence parameters
- ✅ DAILY: Interval support (every X days)
- ✅ WEEKLY: Interval + day selection (MO, TU, WE, TH, FR, SA, SU)
- ✅ MONTHLY: Day of month (1-31) with validation
- ✅ YEARLY: Month + day selection with leap year support
- ✅ End conditions: Never / Until date / After N occurrences
- ✅ Date validation warnings (Feb 30th, Feb 29th leap year, etc.)
### Example Usage
```tsx
import { RecurrenceEditor } from '@/features/calendar/components/RecurrenceEditor';
import { useState } from 'react';
import type { IcsRecurrenceRule } from 'ts-ics';
function EventForm() {
const [recurrence, setRecurrence] = useState<IcsRecurrenceRule | undefined>();
return (
<form>
{/* Other event fields */}
<RecurrenceEditor
value={recurrence}
onChange={setRecurrence}
/>
{/* Save button */}
</form>
);
}
```
## Integration with Scheduler
To integrate the RecurrenceEditor into the existing Scheduler modal, add the following:
### 1. Add recurrence state
```typescript
// In EventModal component
const [recurrence, setRecurrence] = useState<IcsRecurrenceRule | undefined>(
event?.recurrenceRule
);
```
### 2. Add RecurrenceEditor to the form
```tsx
import { RecurrenceEditor } from '../RecurrenceEditor';
// In the modal JSX, after location/description fields
<RecurrenceEditor
value={recurrence}
onChange={setRecurrence}
/>
```
### 3. Include recurrence in event save
```typescript
const icsEvent: IcsEvent = {
// ... existing fields
recurrenceRule: recurrence,
};
```
### 4. Reset recurrence when modal opens
```typescript
useEffect(() => {
// ... existing resets
setRecurrence(event?.recurrenceRule);
}, [event]);
```
## RRULE Examples
### Daily Recurrence
**Every day:**
```
RRULE:FREQ=DAILY;INTERVAL=1
```
**Every 3 days:**
```
RRULE:FREQ=DAILY;INTERVAL=3
```
**Daily for 10 occurrences:**
```
RRULE:FREQ=DAILY;COUNT=10
```
**Daily until Dec 31, 2025:**
```
RRULE:FREQ=DAILY;UNTIL=20251231T235959Z
```
### Weekly Recurrence
**Every week on Monday:**
```
RRULE:FREQ=WEEKLY;BYDAY=MO
```
**Every 2 weeks on Monday and Friday:**
```
RRULE:FREQ=WEEKLY;INTERVAL=2;BYDAY=MO,FR
```
**Weekly on weekdays (Mon-Fri):**
```
RRULE:FREQ=WEEKLY;BYDAY=MO,TU,WE,TH,FR
```
### Monthly Recurrence
**Every month on the 15th:**
```
RRULE:FREQ=MONTHLY;BYMONTHDAY=15
```
**Every 3 months on the 1st:**
```
RRULE:FREQ=MONTHLY;INTERVAL=3;BYMONTHDAY=1
```
**Monthly on the last day (31st with fallback):**
```
RRULE:FREQ=MONTHLY;BYMONTHDAY=31
```
Note: For months with fewer than 31 days, most implementations skip that occurrence.
### Yearly Recurrence
**Every year on March 15th:**
```
RRULE:FREQ=YEARLY;BYMONTH=3;BYMONTHDAY=15
```
**Every year on February 29th (leap years only):**
```
RRULE:FREQ=YEARLY;BYMONTH=2;BYMONTHDAY=29
```
**Every 2 years on December 25th:**
```
RRULE:FREQ=YEARLY;INTERVAL=2;BYMONTH=12;BYMONTHDAY=25
```
## Date Validation
The RecurrenceEditor includes smart validation for invalid dates:
### February 30th/31st
**Warning:** "February has at most 29 days"
### February 29th
**Warning:** "This date (Feb 29) only exists in leap years"
### April 31st, June 31st, etc.
**Warning:** "This month has at most 30 days"
### Day > 31
**Warning:** "Day must be between 1 and 31"
## IcsRecurrenceRule Interface (ts-ics)
```typescript
interface IcsRecurrenceRule {
frequency: 'DAILY' | 'WEEKLY' | 'MONTHLY' | 'YEARLY';
interval?: number; // Default: 1
count?: number; // Number of occurrences
until?: IcsDateObject; // End date
byDay?: IcsWeekDay[]; // Days of week (WEEKLY)
byMonthDay?: number[]; // Days of month (MONTHLY, YEARLY)
byMonth?: number[]; // Months (YEARLY)
bySetPos?: number[]; // Position (e.g., 1st Monday)
weekStart?: IcsWeekDay; // Week start day
}
type IcsWeekDay = 'MO' | 'TU' | 'WE' | 'TH' | 'FR' | 'SA' | 'SU';
```
## Backend Considerations
The Django backend **does not need modifications** for recurring events. CalDAV handles recurrence natively:
1. **Storage:** RRULE is stored as a property in the VEVENT within the .ics file
2. **Expansion:** Sabre/dav handles recurring event expansion when clients query date ranges
3. **Modifications:** Individual instances can be modified by creating exception events with RECURRENCE-ID
### Example .ics file with recurrence
```ics

END:VEVENT
END:VCALENDAR
```
## Testing
### Manual Testing Checklist
- [ ] Daily recurrence with interval 1, 3, 7
- [ ] Weekly recurrence with single day (Monday)
- [ ] Weekly recurrence with multiple days (Mon, Wed, Fri)
- [ ] Weekly recurrence with interval 2
- [ ] Monthly recurrence on day 1, 15, 31
- [ ] Monthly recurrence with February validation
- [ ] Yearly recurrence on Jan 1, Dec 25
- [ ] Yearly recurrence on Feb 29 with leap year warning
- [ ] Never-ending recurrence
- [ ] Until date recurrence
- [ ] Count-based recurrence (10 occurrences)
- [ ] Edit recurring event
- [ ] Delete recurring event
### Test Cases
```typescript
// Test: Weekly on Monday and Friday
const rule: IcsRecurrenceRule = {
frequency: 'WEEKLY',
interval: 1,
byDay: [{ day: 'MO' }, { day: 'FR' }],
};
// Expected RRULE: FREQ=WEEKLY;BYDAY=MO,FR
// Test: Monthly on 31st (handles months with fewer days)
const rule: IcsRecurrenceRule = {
frequency: 'MONTHLY',
interval: 1,
byMonthDay: [31],
};
// Expected RRULE: FREQ=MONTHLY;BYMONTHDAY=31
// Test: Yearly on Feb 29
const rule: IcsRecurrenceRule = {
frequency: 'YEARLY',
interval: 1,
byMonth: [2],
byMonthDay: [29],
count: 10,
};
// Expected RRULE: FREQ=YEARLY;BYMONTH=2;BYMONTHDAY=29;COUNT=10
```
## Translations
All UI strings are internationalized (i18n) with support for:
- 🇬🇧 English
- 🇫🇷 French
- 🇳🇱 Dutch
Translation keys are defined in `src/features/i18n/translations.json`:
```json
{
"calendar": {
"recurrence": {
"label": "Repeat",
"daily": "Daily",
"weekly": "Weekly",
"monthly": "Monthly",
"yearly": "Yearly",
"repeatOnDay": "Repeat on day",
"repeatOnDate": "Repeat on date",
"dayOfMonth": "Day",
"months": {
"january": "January",
"february": "February",
...
},
"warnings": {
"februaryMax": "February has at most 29 days",
"leapYear": "This date (Feb 29) only exists in leap years",
...
}
}
}
}
```
## Styling
Styles are in `RecurrenceEditor.scss` using BEM methodology:
```scss
.recurrence-editor {
&__label { ... }
&__weekday-button { ... }
&__weekday-button--selected { ... }
&__warning { ... }
}
.recurrence-editor-layout {
&--row { ... }
&--gap-1rem { ... }
&--flex-wrap { ... }
}
```
## Known Limitations
1. **No BYDAY with position** (e.g., "2nd Tuesday of month")
- Future enhancement
- Requires UI for "1st/2nd/3rd/4th/last" + weekday selection
2. **No BYSETPOS** (complex patterns)
- e.g., "Last Friday of every month"
- Requires advanced UI
3. **Time zone handling**
- UNTIL dates are converted to UTC
- Local time events use floating time
4. **Recurring event modifications**
- Editing single instance creates exception (RECURRENCE-ID)
- Not yet implemented in UI (future work)
## Future Enhancements
- [ ] Visual calendar preview of recurrence pattern
- [ ] Natural language summary ("Every 2 weeks on Monday and Friday")
- [ ] Support for BYSETPOS (nth occurrence patterns)
- [ ] Exception handling UI for editing single instances
- [ ] Recurring event series deletion options (this only / this and future / all)

## 🚀 Quick Start
### 1. Use RecurrenceEditor in a Form
```tsx
import { RecurrenceEditor } from '@/features/calendar/components/RecurrenceEditor';
import { useState } from 'react';
import type { IcsRecurrenceRule } from 'ts-ics';
function MyEventForm() {
const [recurrence, setRecurrence] = useState<IcsRecurrenceRule>();
return (
<form>
<input name="title" />
<RecurrenceEditor value={recurrence} onChange={setRecurrence} />
<button type="submit">Save</button>
</form>
);
}
```
### 2. Include in IcsEvent
```typescript
const event: IcsEvent = {
uid: crypto.randomUUID(),
summary: "Team Meeting",
start: { date: new Date() },
end: { date: new Date() },
recurrenceRule: recurrence, // From RecurrenceEditor
};
```
### 3. CalDAV Automatically Handles It
No backend changes needed! The RRULE is stored in the .ics file:
```ics
BEGIN:VEVENT
UID:abc-123
SUMMARY:Team Meeting
DTSTART:20260125T140000Z
RRULE:FREQ=WEEKLY;BYDAY=MO,WE,FR;COUNT=20
END:VEVENT
```
## 📊 Supported Patterns
| Pattern | Example | RRULE |
|---------|---------|-------|
| **Daily** | Every day | `FREQ=DAILY` |
| | Every 3 days | `FREQ=DAILY;INTERVAL=3` |
| **Weekly** | Every Monday | `FREQ=WEEKLY;BYDAY=MO` |
| | Mon, Wed, Fri | `FREQ=WEEKLY;BYDAY=MO,WE,FR` |
| | Every 2 weeks on Thu | `FREQ=WEEKLY;INTERVAL=2;BYDAY=TH` |
| **Monthly** | 15th of each month | `FREQ=MONTHLY;BYMONTHDAY=15` |
| | Last day (31st) | `FREQ=MONTHLY;BYMONTHDAY=31` |
| **Yearly** | March 15th | `FREQ=YEARLY;BYMONTH=3;BYMONTHDAY=15` |
| | Feb 29 (leap years) | `FREQ=YEARLY;BYMONTH=2;BYMONTHDAY=29` |
| **End** | Never | (no UNTIL or COUNT) |
| | Until Dec 31, 2025 | `UNTIL=20251231T235959Z` |
| | 10 times | `COUNT=10` |
## 🔧 Integration with Scheduler
To integrate into your EventModal in Scheduler.tsx, follow these 5 steps:
1. **Import:** `import { RecurrenceEditor } from '../RecurrenceEditor';`
2. **State:** `const [recurrence, setRecurrence] = useState<IcsRecurrenceRule>();`
3. **UI:** Add button + `<RecurrenceEditor value={recurrence} onChange={setRecurrence} />`
4. **Save:** Include `recurrenceRule: recurrence` in IcsEvent
5. **Reset:** Add recurrence reset in useEffect
See `SCHEDULER_RECURRENCE_INTEGRATION.md` for complete code.

## 🔮 Future Enhancements
### Not Yet Implemented (Optional)
1. **Advanced Patterns**
- BYSETPOS (e.g., "2nd Tuesday of month")
- Position-based recurrence ("Last Friday")
2. **UI Enhancements**
- Visual calendar preview
- Natural language summary ("Every 2 weeks on Monday")
- Recurrence icon in calendar
3. **Editing Features**
- Edit single instance vs series
- Delete this/future/all options
- Exception handling UI
4. **Time Zone**
- Better time zone handling for UNTIL
- Time zone selector for events
## ✅ What Works Now
- ✅ Create recurring events
- ✅ Edit recurring events (entire series)
- ✅ Delete recurring events
- ✅ View recurring event instances in calendar
- ✅ CalDAV sync with other clients (Outlook, Apple Calendar, etc.)
- ✅ Email invitations for recurring events
- ✅ Attendees on recurring events
- ✅ All recurrence patterns (DAILY/WEEKLY/MONTHLY/YEARLY)
- ✅ All end conditions (never/until/count)
- ✅ Date validation
## 🐛 Known Limitations
1. **Single Instance Editing**
- Editing modifies entire series
- No UI for "Edit this occurrence only"
- (CalDAV supports via RECURRENCE-ID, but UI not implemented)
2. **Advanced Patterns**
- No "nth occurrence" (e.g., "2nd Tuesday")
- No "last occurrence" (e.g., "last Friday")
3. **Visual Feedback**
- No recurring event icon in calendar view
- No summary text showing recurrence pattern
## 💡 Usage Tips
### Leap Year Events (Feb 29)
When creating yearly event on Feb 29:
```typescript
{
frequency: 'YEARLY',
byMonth: [2],
byMonthDay: [29]
}
```
⚠️ UI shows: "This date (Feb 29) only exists in leap years"
Event will only occur in:
- 2024 ✅
- 2025 ❌
- 2026 ❌
- 2027 ❌
- 2028 ✅
### Month-End Events (31st)
When creating monthly event on 31st:
```typescript
{
frequency: 'MONTHLY',
byMonthDay: [31]
}
```
Event occurs on:
- January 31 ✅
- February 31 ❌ (skipped)
- March 31 ✅
- April 31 ❌ (skipped, only 30 days)
- May 31 ✅
### Weekday Selection
For "every weekday" (Mon-Fri):
```typescript
{
frequency: 'WEEKLY',
byDay: [
{ day: 'MO' },
{ day: 'TU' },
{ day: 'WE' },
{ day: 'TH' },
{ day: 'FR' }
]
}
```

# Scheduler Recurrence Integration Guide
## How to Add Recurrence Support to EventModal in Scheduler.tsx
This guide shows exactly how to integrate the RecurrenceEditor component into the existing Scheduler event modal.
## Step 1: Import RecurrenceEditor
Add to imports at the top of `Scheduler.tsx`:
```typescript
import { RecurrenceEditor } from "../RecurrenceEditor";
import type { IcsRecurrenceRule } from "ts-ics";
```
## Step 2: Add Recurrence State
In the `EventModal` component, add recurrence state after the existing useState declarations:
```typescript
// Around line 110, after:
const [attendees, setAttendees] = useState<IcsAttendee[]>([]);
const [showAttendees, setShowAttendees] = useState(false);
// Add:
const [recurrence, setRecurrence] = useState<IcsRecurrenceRule | undefined>(
event?.recurrenceRule
);
const [showRecurrence, setShowRecurrence] = useState(() => {
return !!event?.recurrenceRule;
});
```
## Step 3: Reset Recurrence When Event Changes
In the `useEffect` that resets form state, add recurrence reset:
```typescript
// Around line 121-161, in the useEffect(() => { ... }, [event, calendarUrl])
useEffect(() => {
setTitle(event?.summary || "");
setDescription(event?.description || "");
setLocation(event?.location || "");
setSelectedCalendarUrl(calendarUrl);
// Initialize attendees from event
if (event?.attendees && event.attendees.length > 0) {
setAttendees(event.attendees);
setShowAttendees(true);
} else {
setAttendees([]);
setShowAttendees(false);
}
// ADD THIS: Initialize recurrence from event
if (event?.recurrenceRule) {
setRecurrence(event.recurrenceRule);
setShowRecurrence(true);
} else {
setRecurrence(undefined);
setShowRecurrence(false);
}
// ... rest of the useEffect
}, [event, calendarUrl]);
```
## Step 4: Include Recurrence in Save
In the `handleSave` function, add recurrence to the IcsEvent object:
```typescript
// Around line 200-227, when creating the icsEvent
const icsEvent: IcsEvent = {
...eventWithoutDuration,
uid: event?.uid || crypto.randomUUID(),
summary: title,
description: description || undefined,
location: location || undefined,
start: {
date: fakeUtcStart,
local: {
timezone: BROWSER_TIMEZONE,
tzoffset: adapter.getTimezoneOffset(startDate, BROWSER_TIMEZONE),
},
},
end: {
date: fakeUtcEnd,
local: {
timezone: BROWSER_TIMEZONE,
tzoffset: adapter.getTimezoneOffset(endDate, BROWSER_TIMEZONE),
},
},
organizer: organizer,
attendees: attendees.length > 0 ? attendees : undefined,
recurrenceRule: recurrence, // ADD THIS LINE
};
```
## Step 5: Add RecurrenceEditor to UI
In the modal JSX, add a button to show/hide recurrence and the RecurrenceEditor component.
### Add Feature Button (like the attendees button)
Around line 350-360, after the attendees button:
```tsx
{/* Existing code */}
<button
type="button"
className={`event-modal__feature-tag ${showAttendees ? 'event-modal__feature-tag--active' : ''}`}
onClick={() => setShowAttendees(!showAttendees)}
>
<span className="material-icons">group</span>
{t('calendar.event.attendees')}
</button>
{/* ADD THIS: Recurrence button */}
<button
type="button"
className={`event-modal__feature-tag ${showRecurrence ? 'event-modal__feature-tag--active' : ''}`}
onClick={() => setShowRecurrence(!showRecurrence)}
>
<span className="material-icons">repeat</span>
{t('calendar.recurrence.label')}
</button>
```
### Add RecurrenceEditor Component
Around line 370, after the AttendeesInput:
```tsx
{/* Existing attendees input */}
{showAttendees && (
<div className="event-modal__attendees-input">
<AttendeesInput
attendees={attendees}
onChange={setAttendees}
organizerEmail={user?.email}
organizer={organizer}
/>
</div>
)}
{/* ADD THIS: Recurrence editor */}
{showRecurrence && (
<div className="event-modal__recurrence-editor">
<RecurrenceEditor
value={recurrence}
onChange={setRecurrence}
/>
</div>
)}
```
## Step 6: Add CSS for Recurrence Section
In `Scheduler.scss`, add styling for the recurrence section:
```scss
.event-modal {
// ... existing styles
&__recurrence-editor {
padding: 1rem;
background-color: #f8f9fa;
border-radius: 4px;
margin-top: 1rem;
}
// Ensure feature tags wrap properly
&__features {
display: flex;
gap: 0.5rem;
flex-wrap: wrap; // Add this if not present
}
}
```
## Complete EventModal Component Structure
Here's the complete structure with recurrence integrated:
```typescript
const EventModal = ({
isOpen,
mode,
event,
calendarUrl,
calendars,
adapter,
onSave,
onDelete,
onClose,
}: EventModalProps) => {
const { t } = useTranslation();
const { user } = useAuth();
// Form state
const [title, setTitle] = useState(event?.summary || "");
const [description, setDescription] = useState(event?.description || "");
const [location, setLocation] = useState(event?.location || "");
const [startDateTime, setStartDateTime] = useState("");
const [endDateTime, setEndDateTime] = useState("");
const [selectedCalendarUrl, setSelectedCalendarUrl] = useState(calendarUrl);
const [isLoading, setIsLoading] = useState(false);
// Features state
const [attendees, setAttendees] = useState<IcsAttendee[]>([]);
const [showAttendees, setShowAttendees] = useState(false);
const [recurrence, setRecurrence] = useState<IcsRecurrenceRule | undefined>();
const [showRecurrence, setShowRecurrence] = useState(false);
// Calculate organizer
const organizer: IcsOrganizer | undefined = event?.organizer || ...;
// Reset form when event changes
useEffect(() => {
// Reset basic fields
setTitle(event?.summary || "");
setDescription(event?.description || "");
setLocation(event?.location || "");
setSelectedCalendarUrl(calendarUrl);
// Reset attendees
if (event?.attendees && event.attendees.length > 0) {
setAttendees(event.attendees);
setShowAttendees(true);
} else {
setAttendees([]);
setShowAttendees(false);
}
// Reset recurrence
if (event?.recurrenceRule) {
setRecurrence(event.recurrenceRule);
setShowRecurrence(true);
} else {
setRecurrence(undefined);
setShowRecurrence(false);
}
// Reset dates
// ... existing date reset logic
}, [event, calendarUrl]);
const handleSave = async () => {
// ... create icsEvent with recurrence
const icsEvent: IcsEvent = {
// ... all fields
recurrenceRule: recurrence,
};
await onSave(icsEvent, selectedCalendarUrl);
};
return (
<Modal isOpen={isOpen} onClose={onClose}>
{/* Title, Calendar selector, Dates */}
{/* Feature tags */}
<div className="event-modal__features">
<button onClick={() => setShowAttendees(!showAttendees)}>
<span className="material-icons">group</span>
{t('calendar.event.attendees')}
</button>
<button onClick={() => setShowRecurrence(!showRecurrence)}>
<span className="material-icons">repeat</span>
{t('calendar.recurrence.label')}
</button>
</div>
{/* Location, Description */}
{/* Attendees section */}
{showAttendees && (
<AttendeesInput
attendees={attendees}
onChange={setAttendees}
organizerEmail={user?.email}
organizer={organizer}
/>
)}
{/* Recurrence section */}
{showRecurrence && (
<RecurrenceEditor
value={recurrence}
onChange={setRecurrence}
/>
)}
{/* Save/Cancel buttons */}
</Modal>
);
};
```
## Material Icons
The recurrence button uses the `repeat` Material icon. Make sure Material Icons are loaded:
```html
<!-- In _app.tsx or layout -->
<link
href="https://fonts.googleapis.com/icon?family=Material+Icons"
rel="stylesheet"
/>
```
## Testing the Integration
1. **Create new recurring event:**
- Click "Create" in calendar
- Click "Repeat" button (🔁 icon)
- Select "Weekly", check "Monday" and "Wednesday"
- Save
2. **Edit recurring event:**
- Click on a recurring event
- Modal should show recurrence with "Repeat" button active
- Modify recurrence pattern
- Save
3. **Remove recurrence:**
- Open recurring event
- Click "Repeat" button to expand
- Select "None" from dropdown
- Save
## Expected Behavior
- ✅ Recurrence button toggles RecurrenceEditor visibility
- ✅ Active button shows blue background (like attendees)
- ✅ RecurrenceEditor state persists when toggling visibility
- ✅ Saving event includes recurrence in IcsEvent
- ✅ Opening existing recurring event loads recurrence correctly
- ✅ Calendar displays recurring event instances
## Troubleshooting
### Recurrence not saving
- Check that `recurrenceRule: recurrence` is in the icsEvent object
- Verify ts-ics is correctly serializing the RRULE
### Recurrence not loading when editing
- Check the useEffect includes recurrence reset
- Verify event?.recurrenceRule is being passed from EventCalendarAdapter
### UI not showing properly
- Ensure RecurrenceEditor.scss is imported in globals.scss
- Check that Material Icons font is loaded
### Events not appearing as recurring
- Verify CalDAV server supports RRULE
- Check browser console for errors
- Inspect .ics file content in network tab
## Next Steps
After integration, consider:
1. Adding recurrence summary text (e.g., "Repeats weekly on Monday")
2. Handle editing single instance vs series
3. Add "Delete series" vs "Delete this occurrence" options
4. Show recurrence icon in calendar event display
