# CardDAV API Routes Implementation - Fortschritt

**Stand:** 2026-05-04, alle 15 Tasks abgeschlossen ✅
**Plan:** `docs/superpowers/plans/2026-05-04-cardav-api-routes.md`
**Status:** Implementierung vollständig, bereit für Final Review

## Abgeschlossene Tasks

### ✅ Task 1: Multi-Value Array Validators
**Commit:** a715475 + 930800e (fixes)

- Implementiert: `validatePhones()`, `validateEmails()`, `validateAddresses()`
- Location: `server/routes/contacts.js`
- Tests: 33 neue Tests in test-carddav.js
- Validierungen: Arrays, Objekt-Struktur, Pflichtfelder, Max-Längen, Email-Format, isPrimary-Typ, Array-Länge (max 20)

**Review-Findings & Fixes:**
- Spec Compliance: Minor extras (logging) - akzeptabel
- Code Quality Issues behoben:
  - Whitespace-Validierung ergänzt
  - Null-Guards hinzugefügt
  - Email-Format-Check ergänzt
  - isPrimary Typ-Validierung
  - DoS-Schutz: Array-Länge begrenzt auf 20

### ✅ Task 2: CardDAV Router Setup
**Commits:** cf68bff, 930800e

- Erstellt: `server/routes/cardav.js` mit Express Router
- Implementiert: GET /accounts Endpoint
- Test-Infrastruktur:
  - `_setTestDatabase()` / `_resetTestDatabase()` in `server/db.js`
  - before()/after() Hooks in test-carddav.js
  - Migration 30 wird in Tests angewendet
- Tests: 2 Tests (empty array, populated with shape validation)

**Review-Findings & Fixes:**
- Unused imports entfernt (wurden für Task 3 wieder gebraucht)
- Error-Message leakage behoben (generic "Interner Fehler")
- Test-Cleanup mit after() Hook
- `after` aus node:test importiert

- Response: 201 mit `{ account, addressbooks }`
- Tests: 2 Tests (success case, validation failure)

**Test-Mocking:**
- `_mockTestConnection()` in cardav-sync.js hinzugefügt
- Mock gibt fake addressbooks zurück für Tests
- Mock wird in before() gesetzt, in after() zurückgesetzt

**Wichtige Änderung:**
- `addAccount()` Return-Wert geändert von `{ accountId, addressbooks }` zu `{ account: { id, name, cardavUrl, username, createdAt, lastSync }, addressbooks }`

- Verwendet gemockten testConnection für konsistente Test-Results

### ✅ Task 6: GET /accounts/:id/addressbooks - List Addressbooks
**Commit:** 12e8edf

- Query updated addressbooks nach Discovery
- Response: 200 mit Array von addressbooks
- Test: 1 Test (success case)

### ✅ Task 8: Add bool Validator
**Commit:** 362f711

- Implementiert: `bool(val, field)` Validator in server/middleware/validate.js

### ✅ Task 9: PUT /addressbooks/:id - Toggle Addressbook
**Commit:** 9ec7fda

- Implementiert: PUT /addressbooks/:id Route in server/routes/cardav.js
- Validierung: ID muss positive Ganzzahl sein, enabled muss boolean sein
- Delegiert an: `CardDAVSync.toggleAddressbook(id, enabled)`
- Response: 200 mit `{ updated: true, enabled: boolean }`
- Tests: 2 Tests (success case mit toggle, validation failure für invalid enabled)
- bool Validator verwendet

### ✅ Task 10: POST /accounts/:id/sync - Sync Account
**Commit:** 674fe79

- Implementiert: POST /accounts/:id/sync Route in server/routes/cardav.js
- Validierung: ID muss positive Ganzzahl sein

- Queries: Separate Abfragen für `contact_phones`, `contact_emails`, `contact_addresses`
- Mapping: is_primary (Integer DB) → isPrimary (Boolean Response), snake_case → camelCase
- Sortierung: ORDER BY is_primary DESC, id ASC (Primary-Einträge zuerst)
- Response-Format: `{ ...contact, phones: [], emails: [], addresses: [] }`
- Tests: 2 neue Tests
  - Contact mit allen Multi-Value Fields (phones, emails, addresses)

### ✅ Task 15: Mount CardDAV Router
**Commit:** 8891097

- Import hinzugefügt: `import cardavRouter from './routes/cardav.js'`
- Router gemountet: `app.use('/api/v1/contacts/cardav', cardavRouter)`
- Montage-Reihenfolge: CardDAV-Router VOR Contacts-Router (Express route matching order)
- Auth-Middleware: Bereits global angewendet via `requireAuth` in index.js
- CSRF-Middleware: Automatisch über stateChanging-Flag in OpenAPI + CSRF-Middleware
- Integration Tests: Alle 109 Tests bestehen (20 Suites)
- Server startet erfolgreich auf Port 3000

## Wichtige Erkenntnisse

### Test-Infrastruktur
1. **DB-Mocking:** `_setTestDatabase()` / `_resetTestDatabase()` in db.js
2. **CardDAV-Mocking:** `_mockTestConnection()` in cardav-sync.js
3. **before()/after() Pattern:** Setup in before(), Cleanup in after()
4. **Migration 30:** Muss in jedem Test-Setup angewendet werden für CardDAV-Tabellen

### Code-Patterns
1. **Error-Handling:** Immer generic "Interner Fehler", niemals err.message leaken
2. **Validation:** str(), collectErrors(), MAX_TITLE (100), MAX_URL (500)
3. **Response-Format:** `{ data: ... }` für Success, `{ error: ..., code: ... }` für Fehler
4. **Status Codes:** 200 (GET), 201 (POST create), 400 (validation), 500 (server error)

### Konventionen
- Tests nutzen Node built-in test runner (`node:test`)
- Test-DB ist in-memory SQLite (`:memory:`)
- Commits mit Co-Authored-By: Claude Sonnet 4.5
- TDD-Workflow: Test → Run (fail) → Implement → Run (pass) → Commit
