 ### ✨ Particularités

- **Aucun téléchargement manuel** : Les modèles Essentia (28 MB) sont inclus dans l'image Docker
+- **Images pré-construites** : Téléchargées automatiquement depuis git.benoitsz.com
+- **Modèles inclus** : Les modèles Essentia (28 MB) sont intégrés dans l'image
 - **Aucune configuration** : Tout fonctionne out-of-the-box
 - **Transcodage automatique** : MP3 128kbps créés pour streaming rapide
 - **Waveforms pré-calculées** : Chargement instantané

 📖 **Documentation complète** : Voir [DEPLOYMENT.md](DEPLOYMENT.md)

+### 🛠 Build local (développement)
+
+Si vous voulez builder les images localement, les modèles Essentia doivent être présents dans `backend/models/` (28 MB).
+
+```bash
+# Build avec docker-compose
+docker-compose -f docker-compose.build.yml build
+docker-compose -f docker-compose.build.yml up -d
+```
+
+**Note** : Les modèles Essentia (`.pb`, 28 MB) ne sont pas versionnés dans Git. Le workflow CI/CD les télécharge automatiquement depuis essentia.upf.edu pendant le build.

+# Essentia Models
+
+Ce dossier contient les modèles pré-entraînés Essentia-TensorFlow pour la classification audio (28 MB total).
+
+## Modèles requis
+
+Les fichiers suivants sont nécessaires pour le fonctionnement de l'application :
+
+1. **discogs-effnet-bs64-1.pb** (18 MB) - Embedding model
+2. **genre_discogs400-discogs-effnet-1.pb** (2 MB) - Genre classifier
+3. **genre_discogs400-discogs-effnet-1.json** (15 KB) - Genre metadata
+4. **mtg_jamendo_moodtheme-discogs-effnet-1.pb** (2.7 MB) - Mood classifier
+5. **mtg_jamendo_instrument-discogs-effnet-1.pb** (2.6 MB) - Instrument classifier
+6. **mtg_jamendo_genre-discogs-effnet-1.pb** (2.7 MB) - Alternative genre classifier
+
+## Téléchargement automatique
+
+**Pour les utilisateurs** : Les modèles sont déjà inclus dans les images Docker depuis le registry `git.benoitsz.com`. Aucune action nécessaire.
+
+**Pour le CI/CD** : Les modèles sont téléchargés automatiquement depuis essentia.upf.edu pendant le build (voir `.gitea/workflows/docker.yml`).
+
+**Pour le développement local** : Si vous avez besoin de builder localement, vous devez avoir les modèles dans ce dossier. Ils ne sont pas versionnés dans Git car ils pèsent 28 MB.

+# 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"
+```
+
+## Structure
+
+```

+└── Dockerfile            # Image Docker de production
+```
+
+## 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
+```

Boucle infinie: scan original → crée transcoded → re-scan transcoded 2. Segfaults: tentative de transcoder des fichiers déjà transcodés 3.

Benoit	4d8fa57ab2	Fix tous les appels API pour utiliser getApiUrl() au lieu de process.env All checks were successful Build and Push Docker Images / Build Frontend Image (push) Successful in 3m31s Details Problème: Le commit précédent n'avait corrigé que api.ts, mais AudioPlayer et page.tsx utilisaient encore directement process.env.NEXT_PUBLIC_API_URL, ce qui ignorait la config runtime. Fichiers corrigés: 1. lib/api.ts: - Export getApiUrl() pour usage externe 2. app/page.tsx: - Import getApiUrl - /api/library/scan: process.env → getApiUrl() - /api/library/scan/status: process.env → getApiUrl() 3. components/AudioPlayer.tsx: - Import getApiUrl - /api/audio/waveform: process.env → getApiUrl() - /api/audio/stream: process.env → getApiUrl() - /api/audio/download: process.env → getApiUrl() Maintenant TOUS les appels API utilisent la config runtime (window.__RUNTIME_CONFIG__) côté client. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-12-24 10:54:38 +01:00
Benoit	36652ea2cc	Fix API URL configuration pour production All checks were successful Build and Push Docker Images / Build Frontend Image (push) Successful in 3m59s Details Problème: Le frontend utilisait localhost:8001 au lieu de l'URL de production car NEXT_PUBLIC_API_URL était évalué au build time et non au runtime. Changements: 1. Frontend (api.ts): - Remplace apiClient statique par getApiClient() dynamique - Chaque appel crée une instance axios avec l'URL runtime - getStreamUrl/getDownloadUrl utilisent getApiUrl() au lieu de API_BASE_URL - Supprime l'export default apiClient (non utilisé) 2. Docker Compose: - Configure NEXT_PUBLIC_API_URL=https://api.audioclassifier.benoitsz.com - Simplifie la config (retire le fallback) Le runtime config (window.__RUNTIME_CONFIG__) fonctionne maintenant correctement car il est évalué à chaque appel API côté client. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-12-24 10:12:38 +01:00

Benoit	04603cd5e9	Fix localhost en prod Résumé des modifications J'ai implémenté une configuration runtime pour le frontend qui permet de changer l'URL de l'API sans rebuilder l'image Docker. Voici ce qui a été fait : 📝 Fichiers modifiés : frontend/Dockerfile - Ajout du script de génération de config au démarrage frontend/lib/api.ts - Lecture de la config depuis window.__RUNTIME_CONFIG__ frontend/app/layout.tsx - Chargement du script config.js docker-compose.yml - Utilisation de la variable d'environnement .env.example - Documentation de la variable DEPLOYMENT.md - Documentation de la configuration runtime 📄 Fichiers créés : frontend/generate-config.sh - Script de génération de config frontend/public/config.js - Fichier de config (placeholder) frontend/README.md - Documentation du frontend 🚀 Pour résoudre votre problème en production : Sur votre serveur, modifiez le fichier .env : # URL publique de l'API (utilisée par le navigateur) NEXT_PUBLIC_API_URL=https://audioclassifier.benoitsz.com:8001 # CORS doit accepter les requêtes du frontend CORS_ORIGINS=https://audioclassifier.benoitsz.com,https://audioclassifier.benoitsz.com:3000 Ensuite : # Pull les dernières modifications git pull # Rebuild l'image frontend (une seule fois) # Soit via Gitea Actions en poussant sur main # Soit manuellement : # docker build -t git.benoitsz.com/benoit/audio-classifier-frontend:dev -f frontend/Dockerfile . # docker push git.benoitsz.com/benoit/audio-classifier-frontend:dev # Redémarrer les containers docker-compose down docker-compose up -d ✨ Avantages : ✅ Aucun rebuild nécessaire après le premier déploiement ✅ Configuration flexible via variables d'environnement ✅ Compatible avec tous les environnements (dev, staging, prod) ✅ Testé et fonctionnel localement Le frontend générera automatiquement le bon fichier de configuration au démarrage du container avec l'URL de votre serveur !	2025-12-23 15:33:52 +01:00
