+# Frontend - Audio Classifier
+
+Frontend Next.js pour Audio Classifier avec configuration runtime.
+
+## Configuration Runtime
+
+Le frontend utilise un système de **configuration runtime** qui permet de changer l'URL de l'API sans rebuilder l'image Docker.
+
+### Comment ça fonctionne
+
+1. Au démarrage du container, le script `generate-config.sh` génère un fichier `/app/public/config.js`
+2. Ce fichier contient l'URL de l'API basée sur la variable `NEXT_PUBLIC_API_URL`
+3. Le fichier est chargé dans le navigateur via `<Script src="/config.js">`
+4. Le code API lit la configuration depuis `window.__RUNTIME_CONFIG__.API_URL`
+
+### Développement Local
+
+```bash
+# Installer les dépendances
+npm install
+
+# Créer un fichier .env.local
+echo "NEXT_PUBLIC_API_URL=http://localhost:8001" > .env.local
+
+# Lancer en mode dev
+npm run dev
+```
+
+### Production avec Docker
+
+```bash
+# Build l'image
+docker build -t audio-classifier-frontend -f frontend/Dockerfile .
+
+# Lancer avec une URL personnalisée
+docker run -p 3000:3000 \
+  -e NEXT_PUBLIC_API_URL=https://mon-serveur.com:8001 \
+  audio-classifier-frontend
+```
+
+### Docker Compose
+
+```yaml
+frontend:
+  image: audio-classifier-frontend
+  environment:
+    NEXT_PUBLIC_API_URL: ${NEXT_PUBLIC_API_URL:-http://localhost:8001}
+  ports:
+    - "3000:3000"
+```
+

+```

+```
+
+## Variables d'Environnement
+
+- `NEXT_PUBLIC_API_URL` : URL de l'API backend (ex: `https://api.example.com:8001`)
+
+## Troubleshooting
+
+### L'API n'est pas accessible
+
+Vérifiez que :
+1. La variable `NEXT_PUBLIC_API_URL` est correctement définie
+2. Le fichier `/app/public/config.js` existe dans le container
+3. Le navigateur peut accéder à l'URL de l'API (pas de CORS, firewall, etc.)
+
+### Voir la configuration active
+
+Ouvrez la console du navigateur et tapez :
+```javascript
+console.log(window.__RUNTIME_CONFIG__)
+```
+
+### Vérifier la config dans le container
+
+```bash
+docker exec audio_classifier_ui cat /app/public/config.js
+```
