+# Deploiement Frontend Next.js
+
+Guide de deploiement du frontend Next.js sur un serveur Ubuntu.
+
+## Prerequis
+
+- Ubuntu 20.04+ / Debian 11+
+- Acces root ou sudo
+- Node.js 20+
+- Backend Directus deploye (ex: `api.exemple.com`)
+- Nom de domaine configure (ex: `exemple.com`)
+
+## 1. Installation des dependances
+
+```bash
+sudo apt update && sudo apt upgrade -y
+
+# Node.js 22 LTS
+curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
+sudo apt install -y nodejs
+
+# Yarn et PM2
+sudo npm install -g yarn pm2
+
+# Nginx et Certbot
+sudo apt install -y nginx certbot python3-certbot-nginx
+```
+
+## 2. Configuration du projet
+
+```bash
+# Cloner le projet
+git clone <URL_DU_REPO> frontend
+cd frontend
+
+# Configurer l'environnement
+cp .env.sample .env
+nano .env
+```
+
+Variables a modifier dans `.env`:
+
+```env
+DIRECTUS_API_URL=https://api.exemple.com
+DIRECTUS_API_WS_URL=wss://api.exemple.com/websocket
+
+NEXTAUTH_URL=https://exemple.com
+NEXTAUTH_SECRET=<openssl rand -base64 32>
+
+NEXT_PUBLIC_URL=https://exemple.com
+NEXT_PUBLIC_DIRECTUS_API_URL=https://api.exemple.com
+NEXT_PUBLIC_DIRECTUS_API_WS_URL=wss://api.exemple.com/websocket
+```
+
+## 3. Build de production
+
+```bash
+yarn install --frozen-lockfile
+yarn build
+```
+
+## 4. Demarrage avec PM2
+
+```bash
+pm2 start yarn --name "frontend" -- start
+pm2 status
+
+# Demarrage automatique au boot
+pm2 startup
+pm2 save
+```
+
+## 5. Configuration Nginx
+
+```bash
+sudo nano /etc/nginx/sites-available/exemple.com
+```
+
+```nginx
+server {
+    listen 80;
+    listen [::]:80;
+    server_name exemple.com;
+
+    client_max_body_size 10M;
+
+    access_log /var/log/nginx/exemple.com.access.log;
+    error_log /var/log/nginx/exemple.com.error.log;
+
+    location / {
+        proxy_pass http://127.0.0.1:3000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header X-Forwarded-Host $host;
+        proxy_cache_bypass $http_upgrade;
+
+        # Buffer sizes pour les gros headers/cookies (JWT)
+        proxy_buffer_size 128k;
+        proxy_buffers 4 256k;
+        proxy_busy_buffers_size 256k;
+
+        # Timeouts
+        proxy_connect_timeout 60;
+        proxy_send_timeout 60;
+        proxy_read_timeout 60;
+    }
+
+    location /_next/static {
+        proxy_pass http://127.0.0.1:3000;
+        proxy_cache_valid 60m;
+        add_header Cache-Control "public, immutable, max-age=31536000";
+    }
+}
+```
+
+Activer le site:
+
+```bash
+sudo ln -s /etc/nginx/sites-available/exemple.com /etc/nginx/sites-enabled/
+sudo nginx -t && sudo systemctl reload nginx
+```
+
+## 6. Certificat SSL
+
+Verifier le DNS:
+
+```bash
+dig +short exemple.com
+curl -4 ifconfig.me
+```
+
+Obtenir le certificat:
+
+```bash
+sudo certbot --nginx -d exemple.com
+```
+
+## 7. Verification
+
+Ouvrir `https://exemple.com` dans un navigateur.
+
+## Commandes utiles
+
+```bash
+# Logs PM2
+pm2 logs frontend
+
+# Statut
+pm2 status
+
+# Redemarrer
+pm2 restart frontend
+
+# Mise a jour
+git pull origin main
+yarn install --frozen-lockfile
+yarn build
+pm2 restart frontend
+```
+
+## Troubleshooting
+
+### L'application ne demarre pas
+
+```bash
+pm2 logs frontend --lines 50
+ls -la .next/
+yarn start
+```
+
+### Erreur 502
+
+```bash
+pm2 status
+curl http://localhost:3000
+sudo tail -20 /var/log/nginx/exemple.com.error.log
+```
+
+Si le curl local fonctionne mais pas via Nginx, verifier les buffer sizes dans la config Nginx (necessaires pour les gros cookies JWT):
+
+```nginx
+proxy_buffer_size 128k;
+proxy_buffers 4 256k;
+proxy_busy_buffers_size 256k;
+```
+
+### Erreur de connexion API
+
+```bash
+curl https://api.exemple.com/server/health
+cat .env | grep DIRECTUS
+```
+
+### Erreur SSL
+
+```bash
+dig +short exemple.com
+sudo certbot certificates
+sudo certbot renew --force-renewal
+```
+
+## Configuration CORS Backend
+
+Verifier que le backend autorise le frontend dans son `.env`:
+
+```env
+CORS_ENABLED=true
+CORS_ORIGIN=true
+```

+# Leçons — Konstitisyon Frontend
+
+## 2026-04-13 — Rate limiting / Premier chantier
+
+### Erreur commise
+Implémentation directe sans passer par le mode planification ni créer `tasks/todo.md` avant de coder.
+La tâche a été présentée comme terminée après validation XO, sans preuve de fonctionnement réel.
+
+### Règle à retenir
+1. **Toujours** créer/mettre à jour `tasks/todo.md` avant de toucher au code pour toute tâche 3+ étapes.
+2. **Toujours** prouver le fonctionnement après implémentation : test unitaire, `curl`, ou vérification Node directe — pas seulement le linter.
+3. Le linter qui passe ≠ la feature qui fonctionne.
+
+### Ce qui a bien fonctionné
+- Lecture complète des fichiers impactés avant d'écrire (middleware, register, options, package.json)
+- Zéro dépendance externe ajoutée — solution en-mémoire adaptée à PM2 single-process
+- Correction autonome des erreurs XO (curly, arrow-parens, func-names) sans intervention
+- Abstraction propre : `createRateLimiter` est réutilisable pour d'autres routes futures

+# Tâches — Konstitisyon Frontend
+
+## Améliorations critiques (P1)
+
+- [x] **Rate limiting** — `lib/rate-limit.js` + `middleware.js`
+  - Routes protégées : `/api/auth/register` (5/15min) et `/api/auth/callback/credentials` (10/5min)
+  - Logique vérifiée : comptage, blocage 429 + Retry-After, expiration fenêtre ✓
+- [x] **CORS whitelist** — restreindre `CORS_ORIGIN=true` dans l'env Directus
+- [x] **Sanitisation Markdown** — DOMPurify sur la sortie `marked` dans export-pdf et print-button
+
+## Améliorations hautes (P2)
+
+- [x] **Headers CSP** — `next.config.mjs` (renommé depuis .js) avec CSP + 4 headers sécurité
+- [x] **Tests unitaires** — Vitest sur `lib/format.js`, `lib/version-utils.js`, `lib/rate-limit.js`
+- [ ] **Tests extensions Directus** — mocks VersionsService
+- [ ] **Refresh token explicite** — callback `jwt` dans NextAuth options
+- [ ] **Pipeline CI** — GitHub Actions (lint + test + build)
+- [ ] **Sentry** — tracking erreurs frontend + API routes
+
+## Améliorations moyennes (P3)
+
+- [ ] ISR page d'accueil (`revalidate`)
+- [ ] Dockerisation frontend (`output: standalone`)
+- [ ] Audit accessibilité WCAG 2.1
+- [ ] Responsive mobile dashboard
+- [ ] Lazy loading jsPDF + md-editor
+- [ ] Migration NextAuth v5 stable
