# Architektur-Übersicht – Mitai Jinkendo
|
||
|
||
## System-Überblick
|
||
|
||
**Mitai Jinkendo** ist eine selbst-gehostete Progressive Web App (PWA) für Körper-Tracking mit KI-gestützter Auswertung. Die Architektur folgt einem klassischen **3-Tier-Modell** mit klarer Trennung von Präsentation, Business-Logik und Datenhaltung.

## Datenfluss
|
||
|
||
### 1. User Request → Auth → API → Database
|
||
|
||
```
|
||
User Action (Frontend)
|
||
↓
|
||
api.js (Token injiziert via hdrs())
|
||
↓
|
||
FastAPI Endpoint
|
||
↓
|
||
require_auth() Dependency (auth.py)
|
||
↓ (validiert X-Auth-Token → session)
|
||
↓
|
||
get_session() → SELECT FROM sessions JOIN profiles
|
||
↓ (returns session dict mit profile_id, role, ai_enabled, ...)
|
||
↓
|
||
Router-Funktion
|
||
↓
|
||
db.py → get_db() Context Manager
|
||
↓
|
||
psycopg2 → PostgreSQL Query (RealDictCursor)
|
||
↓
|
||
Response (JSON)
|
||
```
|
||
|
||
### 2. Feature Access Control (v9c)
|
||
|
||
```
|
||
Endpoint (z.B. POST /api/insights/run)
|
||
↓
|
||
check_feature_access(profile_id, 'ai_calls')
|
||
↓
|
||
Prüf-Hierarchie:
|
||
1. user_feature_restrictions (user-spezifisch)
|
||
2. tier_limits (Tier-basiert)
|
||
3. features.default_limit (Fallback)
|
||
↓
|
||
get_effective_tier(profile_id)
|
||
→ access_grants (Coupon/Trial) ODER profiles.tier
|
||
↓
|
||
user_feature_usage (aktueller Zähler)
|
||
↓
|
||
Ergebnis: {allowed: bool, limit: int, used: int, remaining: int, reason: str}
|
||
↓
|
||
Falls allowed == false → HTTP 403
|
||
Falls allowed == true → increment_feature_usage() + execute
|
||
```
|
||
|
||
### 3. KI-Pipeline (3-stufig)
|
||
|
||
```
|
||
User: "Analyse starten"
|
||
↓
|
||
POST /api/insights/pipeline
|
||
↓
|
||
check_feature_access('ai_pipeline')
|
||
↓
|
||
Stufe 1: Gewicht-Trend → claude-sonnet-4 (OpenRouter)
|
||
Stufe 2: Ernährung → claude-sonnet-4
|
||
Stufe 3: Gesamtanalyse → claude-sonnet-4 (mit Ergebnissen aus 1+2)
|
||
↓
|
||
Jeder Call: increment_feature_usage('ai_calls')
|
||
↓
|
||
INSERT INTO ai_insights (scope='pipeline', content=...)
|
||
↓
|
||
Return: {content: "...", usage: {...}}
|
||
```
|
||
|
||

|
||
|
||
## Sicherheitsarchitektur
|
||
|
||
### 1. Passwort-Sicherheit
|
||
|
||
**Hash-Verfahren:**
|
||
- **Aktuell:** bcrypt (Salting + Work Factor)
|
||
- **Legacy:** SHA256 (wird beim Login automatisch zu bcrypt migriert)
|
||
|
||
**Passwort-Hashing (`auth.py`):**
|
||
```python
|
||
def hash_pin(pin: str) -> str:
|
||
return bcrypt.hashpw(pin.encode(), bcrypt.gensalt()).decode()
|
||
|
||
def verify_pin(pin: str, stored_hash: str) -> bool:
|
||
if stored_hash.startswith('$2'): # bcrypt
|
||
return bcrypt.checkpw(pin.encode(), stored_hash.encode())
|
||
# Legacy SHA256 → auto-upgrade beim nächsten Login
|
||
return stored_hash == hashlib.sha256(pin.encode()).hexdigest()
|
||
```
|
||
|
||
### 2. Session-Management
|
||
|
||
**Token-Format:**
|
||
- `secrets.token_urlsafe(32)` → 43 Zeichen Base64-URL-safe
|
||
- Gespeichert in `sessions` Tabelle mit `expires_at`
|
||
- Standard-Lebensdauer: 30 Tage (konfigurierbar pro Profil)
|
||
|
||
**Auth-Flow:**
|
||
```python
|
||
# Backend
|
||
@router.post("/api/auth/login")
|
||
def login(email, password):
|
||
profile = SELECT ... WHERE email=...
|
||
verify_pin(password, profile.pin_hash) # ✓
|
||
token = make_token()
|
||
INSERT INTO sessions (token, profile_id, expires_at)
|
||
return {"token": token, "profile": {...}}
|
||
|
||
# Frontend (AuthContext.jsx)
|
||
localStorage.setItem('mitai-jinkendo_token', token)
|
||
```
|
||
|
||
**Auth-Middleware (`auth.py`):**
|
||
```python
|
||
def require_auth(x_auth_token: Optional[str] = Header(default=None)):
|
||
session = get_session(x_auth_token)
|
||
if not session:
|
||
raise HTTPException(401, "Nicht eingeloggt")
|
||
return session # dict mit profile_id, role, ai_enabled, ...
|
||
```
|
||
|
||
### 3. CORS-Konfiguration
|
||
|
||
**Produktion (`docker-compose.yml`):**
|
||
```yaml
|
||
ALLOWED_ORIGINS: https://mitai.jinkendo.de
|
||
```
|
||
|
||
**Development:**
|
||
```yaml
|
||
ALLOWED_ORIGINS: https://dev.mitai.jinkendo.de,http://localhost:3099
|
||
```
|
||
|
||
**FastAPI Setup (`main.py`):**
|
||
```python
|
||
app.add_middleware(
|
||
CORSMiddleware,
|
||
allow_origins=os.getenv("ALLOWED_ORIGINS", "*").split(","),
|
||
allow_credentials=True,
|
||
allow_methods=["GET","POST","PUT","DELETE","OPTIONS"],
|
||
allow_headers=["*"],
|
||
)
|
||
```
|
||
|
||
### 4. Rate Limiting
|
||
|
||
**Library:** slowapi (Redis-freie In-Memory Rate Limiting)
|
||
|
||
**Anwendung:**
|
||
```python
|
||
from slowapi import Limiter
|
||
from slowapi.util import get_remote_address
|
||
|
||
limiter = Limiter(key_func=get_remote_address)
|
||
app.state.limiter = limiter
|
||
|
||
@router.post("/auth/login")
|
||
@limiter.limit("5/minute") # Max 5 Login-Versuche pro Minute
|
||
def login(request: Request, ...):
|
||
...
|
||
```
|
||
|
||
**Geschützte Endpoints:**
|
||
- `/api/auth/login` → 5/minute
|
||
- `/api/auth/register` → 3/minute
|
||
- KI-Endpoints → via Feature-Limits (nicht Rate Limiting)
|
||
|
||
### 5. SQL Injection Protection
|
||
|
||
**Parameter-Binding:**
|
||
```python
|
||
# ✅ Sicher (psycopg2 escaped automatisch):
|
||
cur.execute("SELECT * FROM profiles WHERE id = %s", (profile_id,))
|
||
|
||
# ❌ NIEMALS:
|
||
cur.execute(f"SELECT * FROM profiles WHERE id = '{profile_id}'")
|
||
```
|
||
|
||
**RealDictCursor:**
|
||
- Automatisches Escaping
|
||
- Keine String-Konkatenation
|
||
|
||

|
||
|
||
---
|
||
|
||
## Design-Entscheidungen
|
||
|
||
### Warum PostgreSQL statt SQLite?
|
||
|
||
**Vorteile:**
|
||
- Concurrent Writes (SQLite locked bei Writes)
|
||
- Native UUID Support
|
||
- JSONB für flexible Datenstrukturen (z.B. sleep_segments)
|
||
- Trigger + Stored Procedures
|
||
- Production-ready für Self-Hosting
|
||
|
||
**Migration:**
|
||
- Automatisches Migrations-System (`db_init.py`)
|
||
- Rollback-fähig via SQL-Dateien
|
||
- Tracking in `schema_migrations` Tabelle
|
||
|
||
### Warum FastAPI statt Flask/Django?
|
||
|
||
**Vorteile:**
|
||
- Async Support (für zukünftige WebSocket-Features)
|
||
- Automatic OpenAPI Docs
|
||
- Type Hints → automatische Validierung
|
||
- Dependency Injection (z.B. `require_auth`)
|
||
- Performance (ASGI statt WSGI)
|
||
|
||
### Warum React statt Vue/Svelte?
|
||
|
||
**Entscheidung:**
|
||
- Bekanntes Ecosystem
|
||
- Context API ausreichend (kein Redux nötig)
|
||
- Gute PWA-Integration
|
||
- React Router maturity
|
||
|
||
### Warum kein TypeScript?
|
||
|
||
**Entscheidung (bewusst):**
|
||
- Schnellere Prototyping-Geschwindigkeit
|
||
- Weniger Build-Komplexität
|
||
- Dokumentation via JSDoc-Kommentare
|
||
- Type Safety durch Backend (Pydantic)
|
||
|
||
### Warum Connection Pooling?
|
||
|
||
**Problem ohne Pooling:**
|
||
- Jeder API-Call → neue DB-Verbindung → Overhead
|
||
- PostgreSQL max_connections erreicht bei vielen gleichzeitigen Requests
|
||
|
||
**Lösung:**
|
||
```python
|
||
_pool = psycopg2.pool.SimpleConnectionPool(minconn=1, maxconn=10)
|
||
|
||
@contextmanager
|
||
def get_db():
|
||
conn = _pool.getconn()
|
||
try:
|
||
yield conn
|
||
conn.commit()
|
||
except:
|
||
conn.rollback()
|
||
raise
|
||
finally:
|
||
_pool.putconn(conn)
|
||
```
|
||
|
||
**Vorteil:**
|
||
- Max 10 gleichzeitige Verbindungen
|
||
- Automatisches Recycling
|
||
- Auto-Commit/Rollback
|
||
|

|
||
|
||
## Bekannte Limitationen & Workarounds
|
||
|
||
### 1. Docker Build auf Raspberry Pi
|
||
|
||
**Problem:** `apt-get install postgresql-client` hängt 30+ Minuten
|
||
|
||
**Lösung:** Reine Python-Lösung mit `psycopg2-binary` (keine System-Dependencies)
|
||
|
||
### 2. Apple Health CSV-Import
|
||
|
||
**Problem:** Dezimalwerte werden als String exportiert (`"65.0"` statt `65`)
|
||
|
||
**Lösung:**
|
||
```python
|
||
def safe_float(val):
|
||
try:
|
||
return float(val) if val else None
|
||
except:
|
||
return None
|
||
```

### 3. Bun Crash nach langen Claude Code Sessions
|
||
|
||
**Problem:** Bun (JS Runtime für Claude Code CLI) crashed bei >30 Min Sessions
|
||
|
||
**Workaround:** Bei komplexen Tasks früher committen + neue Session starten
|
||
|
||
### 4. dayjs.week() ohne Plugin
|
||
|
||
**Problem:** `dayjs().week()` existiert nicht ohne `isoWeek`-Plugin
|
||
|
||
**Lösung:** Native ISO-Wochenberechnung:
|
||
```javascript
|
||
const isoWeek = (d => Math.ceil(((new Date(d.setDate(d.getDate()+4-(d.getDay()||7)))-
|
||
new Date(d.getFullYear(),0,1))/86400000+1)/7))(new Date(date))
|
||
```

## Performance-Optimierungen
|
||
|
||
### 1. Frontend
|
||
|
||
- **Code Splitting:** React.lazy() für Admin-Seiten (nicht initial geladen)
|
||
- **Image Loading:** `loading="lazy"` für Photos
|
||
- **CSS:** Inline Critical CSS, kein CSS-in-JS Overhead
|
||
- **PWA Cache:** Service Worker cached statische Assets
|
||
|
||
### 2. Backend
|
||
|
||
- **Connection Pooling:** Max 10 Connections statt unlimited
|
||
- **Query Optimization:** Indizes auf häufig abgefragte Spalten
|
||
- **Lazy Loading:** KI-Analysen nur auf Abruf, nicht im Dashboard
|
||
|
||
### 3. Database
|
||
|
||
**Indizes:**
|
||
```sql
|
||
CREATE INDEX idx_weight_log_profile_date ON weight_log(profile_id, date DESC);
|
||
CREATE INDEX idx_sessions_expires_at ON sessions(expires_at);
|
||
CREATE INDEX idx_ai_insights_profile_scope ON ai_insights(profile_id, scope, created DESC);
|
||
```
|
||
|
||
**Unique Constraints:**
|
||
```sql
|
||
CREATE UNIQUE INDEX idx_weight_log_profile_date_unique ON weight_log(profile_id, date);
|
||
```
|
||

|
||
|
||
## Monitoring & Logging
|
||
|
||
### 1. Feature Usage Logging (v9c Phase 2)
|
||
|
||
**Format:** JSON Lines (JSONL)
|
||
|
||
**Speicherort:** `/app/logs/feature-usage.log`
|
||
|
||
**Beispiel:**
|
||
```json
|
||
{"timestamp":"2026-03-23T10:15:30Z","profile_id":"uuid-here","feature":"ai_calls","allowed":true,"limit":10,"used":3,"remaining":7}
|
||
{"timestamp":"2026-03-23T10:16:00Z","profile_id":"uuid-here","feature":"data_export","allowed":false,"limit":0,"used":0,"remaining":0,"reason":"limit_exceeded"}
|
||
```
|
||
|
||
**Auswertung:**
|
||
```bash
|
||
cat feature-usage.log | jq -s 'group_by(.feature) | map({feature: .[0].feature, total: length})'
|
||
```
|
||
|
||
### 2. Health Checks
|
||
|
||
**Database:**
|
||
```yaml
|
||
healthcheck:
|
||
test: ["CMD-SHELL", "pg_isready -U mitai_prod"]
|
||
interval: 10s
|
||
```
|
||
|
||
**API:**
|
||
```python
|
||
@app.get("/")
|
||
def root():
|
||
return {"status": "ok", "service": "mitai-jinkendo", "version": "v9c-dev"}
|
||
```
|
||
|
||
### 3. Error Handling
|
||
|
||
**Einheitliches Format:**
|
||
```python
|
||
raise HTTPException(status_code=404, detail="Eintrag nicht gefunden")
|
||
# → {"detail": "Eintrag nicht gefunden"}
|
||
```
|
||
|
||
**Frontend (`api.js`):**
|
||
```javascript
|
||
if (!res.ok) {
|
||
const err = await res.text()
|
||
try {
|
||
const parsed = JSON.parse(err)
|
||
throw new Error(parsed.detail || err)
|
||
} catch {
|
||
throw new Error(err)
|
||
}
|
||
}
|
||
```
|
