+# CI/CD and Deployment Documentation
+
+This directory contains the CI/CD configuration for the project.
+
+## Testing
+
+The project includes end-to-end (e2e) tests to ensure the API endpoints work correctly. The tests are located in the `backend/test` directory.
+
+### Running E2E Tests
+
+```bash
+# Navigate to the backend directory
+cd backend
+
+# Run e2e tests
+npm run test:e2e
+```
+
+### Test Structure
+
+- `app.e2e-spec.ts`: Tests the basic API endpoint (/api)
+- `auth.e2e-spec.ts`: Tests authentication endpoints including:
+  - User profile retrieval
+  - Token refresh
+  - GitHub OAuth redirection
+- `test-utils.ts`: Utility functions for testing including:
+  - Creating test applications
+  - Creating test users
+  - Generating authentication tokens
+  - Cleaning up test data
+
+## CI/CD Workflow
+
+The CI/CD pipeline is configured using GitHub Actions and is defined in the `.github/workflows/ci-cd.yml` file. The workflow consists of the following steps:
+
+### Build and Test
+
+This job runs on every push to the main branch and on pull requests:
+
+1. Sets up Node.js and pnpm
+2. Installs dependencies
+3. Builds and tests the backend
+4. Builds and lints the frontend
+
+### Build and Push Docker Images
+
+This job runs only on pushes to the main branch:
+
+1. Sets up Docker Buildx
+2. Logs in to GitHub Container Registry
+3. Builds and pushes the backend Docker image
+4. Builds and pushes the frontend Docker image
+
+## Deployment
+
+The application is containerized using Docker. Dockerfiles are provided for both the backend and frontend:
+
+- `backend/Dockerfile`: Multi-stage build for the NestJS backend
+- `frontend/Dockerfile`: Multi-stage build for the Next.js frontend
+
+A `docker-compose.yml` file is also provided at the root of the project for local development and as a reference for deployment.
+
+### Running Locally with Docker Compose
+
+```bash
+# Build and start all services
+docker-compose up -d
+
+# View logs
+docker-compose logs -f
+
+# Stop all services
+docker-compose down
+```
+
+### Environment Variables
+
+The following environment variables are used in the deployment:
+
+#### Backend
+- `NODE_ENV`: Environment (development, production)
+- `PORT`: Port on which the backend runs
+- `POSTGRES_HOST`: PostgreSQL host
+- `POSTGRES_PORT`: PostgreSQL port
+- `POSTGRES_DB`: PostgreSQL database name
+- `POSTGRES_USER`: PostgreSQL username
+- `POSTGRES_PASSWORD`: PostgreSQL password
+
+#### Frontend
+- `NODE_ENV`: Environment (development, production)
+- `PORT`: Port on which the frontend runs
+- `NEXT_PUBLIC_API_URL`: URL of the backend API
+
+## Production Deployment Considerations
+
+For production deployment, consider the following:
+
+1. Use a proper secrets management solution for sensitive information
+2. Set up proper networking and security groups
+3. Configure a reverse proxy (like Nginx) for SSL termination
+4. Set up monitoring and logging
+5. Configure database backups

-# Plan d'Implémentation de l'Authentification
-
-Ce document détaille le plan d'implémentation du système d'authentification pour l'application de création de groupes, basé sur les spécifications du cahier des charges.
-
-## 1. Vue d'Ensemble
-
-L'application utilisera OAuth 2.0 avec GitHub comme fournisseur d'identité, combiné avec une gestion de session basée sur JWT (JSON Web Tokens). Cette approche offre plusieurs avantages :
-
-- Délégation de l'authentification à un service tiers sécurisé (GitHub)
-- Pas besoin de gérer les mots de passe des utilisateurs
-- Récupération des informations de profil (nom, avatar) depuis l'API GitHub
-- Authentification stateless avec JWT pour une meilleure scalabilité
-
-## 2. Flux d'Authentification

-## 5. Sécurité et Bonnes Pratiques
-
-### 5.1 Gestion des Tokens
-
-- **Access Token** : Durée de vie courte (15 minutes) pour limiter les risques en cas de vol
-- **Refresh Token** : Durée de vie plus longue (7 jours) pour permettre le rafraîchissement de l'access token
-- Stockage sécurisé des tokens côté client (localStorage pour l'access token, httpOnly cookie pour le refresh token dans une implémentation plus sécurisée)
-- Révocation des tokens en cas de déconnexion ou de suspicion de compromission
-
-### 5.2 Protection contre les Attaques Courantes
-
-- **CSRF** : Utilisation de tokens anti-CSRF pour les opérations sensibles
-- **XSS** : Échappement des données utilisateur, utilisation de Content Security Policy
-- **Injection** : Validation des entrées avec class-validator, utilisation de paramètres préparés avec DrizzleORM
-- **Rate Limiting** : Limitation du nombre de requêtes d'authentification pour prévenir les attaques par force brute
-
-### 5.3 Conformité RGPD
-
-- Enregistrement du timestamp d'acceptation RGPD lors de la création du compte
-- Possibilité d'exporter les données personnelles
-- Possibilité de supprimer le compte et toutes les données associées
-- Renouvellement du consentement tous les 13 mois
-
-## 6. Intégration avec le Frontend

-# Plan d'Implémentation du Schéma de Base de Données
-
-Ce document détaille le plan d'implémentation du schéma de base de données pour l'application de création de groupes, basé sur le modèle de données spécifié dans le cahier des charges.
-
-## 1. Schéma DrizzleORM
-
-Le schéma sera implémenté en utilisant DrizzleORM avec PostgreSQL. Voici la définition des tables et leurs relations.
-
-### 1.1 Table `users`
-
-```typescript
-import { pgTable, uuid, varchar, text, timestamp, jsonb } from 'drizzle-orm/pg-core';
-
-export const users = pgTable('users', {
-  id: uuid('id').primaryKey().defaultRandom(), // UUIDv7 pour l'ordre chronologique
-  name: varchar('name', { length: 100 }).notNull(),
-  avatar: text('avatar'), // URL depuis l'API Github
-  githubId: varchar('githubId', { length: 50 }).notNull().unique(),
-  gdprTimestamp: timestamp('gdprTimestamp', { withTimezone: true }),
-  createdAt: timestamp('createdAt', { withTimezone: true }).defaultNow().notNull(),
-  updatedAt: timestamp('updatedAt', { withTimezone: true }).defaultNow().notNull(),
-  metadata: jsonb('metadata').default({})
-}, (table) => {
-  return {

-## 3. Migrations
-
-### 3.1 Configuration de Drizzle Kit
-
-Créer un fichier `drizzle.config.ts` à la racine du projet backend :
-
-```typescript
-import type { Config } from 'drizzle-kit';
-import * as dotenv from 'dotenv';
-
-dotenv.config();
-
-export default {
-  schema: './src/database/schema/*.ts',
-  out: './src/database/migrations',
-  driver: 'pg',
-  dbCredentials: {
-    connectionString: process.env.DATABASE_URL || 'postgres://postgres:postgres@localhost:5432/groupmaker',
-  },
-  verbose: true,
-  strict: true,
-} satisfies Config;
-```
-
-### 3.2 Scripts pour les Migrations
-
-Ajouter les scripts suivants au `package.json` du backend :
-
-```json
-{
-  "scripts": {
-    "db:generate": "drizzle-kit generate:pg",
-    "db:migrate": "ts-node src/database/migrate.ts",
-    "db:studio": "drizzle-kit studio"
-  }

-Créer un fichier `src/database/migrate.ts` :
-
-```typescript
-import { drizzle } from 'drizzle-orm/node-postgres';
-import { migrate } from 'drizzle-orm/node-postgres/migrator';
-import { Pool } from 'pg';
-import * as dotenv from 'dotenv';
-
-dotenv.config();
-
-const main = async () => {
-  const pool = new Pool({
-    connectionString: process.env.DATABASE_URL,
-  });
-
-  const db = drizzle(pool);
-
-  console.log('Running migrations...');
-  
-  await migrate(db, { migrationsFolder: './src/database/migrations' });
-  
-  console.log('Migrations completed successfully');
-  
-  await pool.end();
-};
-
-main().catch((err) => {
-  console.error('Migration failed');
-  console.error(err);
-  process.exit(1);
-});
-```
-
-## 4. Module de Base de Données
-
-### 4.1 Module Database
-
-Créer un fichier `src/database/database.module.ts` :
-
-```typescript
-import { Module, Global } from '@nestjs/common';
-import { ConfigModule, ConfigService } from '@nestjs/config';
-import { Pool } from 'pg';
-import { drizzle } from 'drizzle-orm/node-postgres';
-import * as schema from './schema';
-
-export const DATABASE_POOL = 'DATABASE_POOL';
-export const DRIZZLE = 'DRIZZLE';
-
-@Global()
-@Module({
-  imports: [ConfigModule],
-  providers: [
-    {
-      provide: DATABASE_POOL,
-      inject: [ConfigService],
-      useFactory: async (configService: ConfigService) => {
-        const pool = new Pool({
-          connectionString: configService.get<string>('DATABASE_URL'),
-        });
-        
-        // Test the connection
-        const client = await pool.connect();
-        try {
-          await client.query('SELECT NOW()');
-          console.log('Database connection established successfully');
-        } finally {
-          client.release();
-        }
-        
-        return pool;
-      },
-    },
-    {
-      provide: DRIZZLE,
-      inject: [DATABASE_POOL],
-      useFactory: (pool: Pool) => {
-        return drizzle(pool, { schema });
-      },
-    },
-  ],
-  exports: [DATABASE_POOL, DRIZZLE],
-})
-export class DatabaseModule {}
-```
-
-### 4.2 Index des Schémas
-
-Créer un fichier `src/database/schema/index.ts` pour exporter tous les schémas :
-
-```typescript
-export * from './users';
-export * from './projects';
-export * from './persons';
-export * from './groups';
-export * from './tags';
-export * from './personToGroup';
-export * from './personToTag';
-export * from './projectToTag';
-export * from './enums';
-export * from './relations';
-```
-
-## 5. Stratégie d'Indexation
-
-Les index suivants seront créés pour optimiser les performances des requêtes :
-
-1. **Index Primaires** : Sur toutes les clés primaires (UUIDv7)
-2. **Index Secondaires** : Sur les clés étrangères pour accélérer les jointures
-3. **Index Composites** : Sur les champs fréquemment utilisés ensemble dans les requêtes
-4. **Index Partiels** : Pour les requêtes filtrées fréquentes
-5. **Index de Texte** : Pour les recherches sur les champs textuels (noms, descriptions)
-
-## 6. Optimisation des Formats de Données
-
-Les types de données PostgreSQL seront optimisés pour chaque cas d'usage :
-
-1. **UUID** : Pour les identifiants (UUIDv7 pour l'ordre chronologique)
-2. **JSONB** : Pour les données flexibles et semi-structurées (metadata, settings, attributes)
-3. **ENUM** : Types PostgreSQL natifs pour les valeurs fixes (gender, oralEaseLevel, tagType)
-4. **VARCHAR** : Avec contraintes pour les chaînes de caractères variables
-5. **TIMESTAMP WITH TIME ZONE** : Pour les dates avec gestion des fuseaux horaires
-6. **SMALLINT** : Pour les valeurs numériques entières de petite taille (technicalLevel, age)
-7. **BOOLEAN** : Pour les valeurs booléennes (hasTechnicalTraining)
-
-Ces optimisations permettront d'améliorer les performances des requêtes, de réduire l'empreinte mémoire et d'assurer l'intégrité des données.

-## 1. Vue d'Ensemble
-
-L'application est une plateforme de création et de gestion de groupes qui permet aux utilisateurs de créer des groupes en prenant en compte divers paramètres et de conserver un historique des groupes précédemment créés.
-
-### 1.1 Architecture Globale
-
-L'application suit une architecture monorepo avec séparation claire entre le frontend et le backend :
-
-- **Frontend** : Application Next.js avec App Router et Server Components
-- **Backend** : API NestJS avec PostgreSQL et DrizzleORM
-- **Communication** : API REST pour les opérations CRUD et WebSockets pour les mises à jour en temps réel
-- **Authentification** : OAuth 2.0 avec GitHub et JWT pour la gestion des sessions

-
-Ce projet utilise PNPM pour la gestion du workspace et des packages. PNPM offre plusieurs avantages :
-
-- **Efficacité de stockage** : Utilise un stockage partagé pour éviter la duplication des packages
-- **Gestion de monorepo** : Facilite la gestion des dépendances entre les packages du monorepo
-- **Performance** : Installation et mise à jour des dépendances plus rapides
-- **Déterminisme** : Garantit que les mêmes dépendances sont installées de manière cohérente
-
-Pour travailler avec les différents packages du monorepo :
+Vous pouvez également utiliser Docker pour démarrer l'application complète :
 
 ```bash
-# Exécuter une commande dans un package spécifique
-pnpm --filter <package-name> <command>
+# À la racine du projet
+docker-compose up -d
+```
 
-# Exemple : démarrer le frontend uniquement
-pnpm --filter web dev
+### Gestion des Projets Backend et Frontend
 
-# Installer une dépendance dans un package spécifique

-# Plan d'Implémentation des WebSockets
-
-Ce document détaille le plan d'implémentation du système de communication en temps réel via WebSockets pour l'application de création de groupes, basé sur les spécifications du cahier des charges.
-
-## 1. Vue d'Ensemble
-
-L'application utilisera Socket.IO pour établir une communication bidirectionnelle en temps réel entre le client et le serveur. Cette fonctionnalité permettra :
-
-- La mise à jour instantanée des groupes
-- Les notifications en temps réel
-- La collaboration simultanée entre utilisateurs

+### End-to-End (E2E) Tests
+
+The project includes comprehensive end-to-end tests to ensure API endpoints work correctly. These tests are located in the `test` directory:
+
+- `app.e2e-spec.ts`: Tests the basic API endpoint (/api)
+- `auth.e2e-spec.ts`: Tests authentication endpoints including:
+  - User profile retrieval
+  - Token refresh
+  - GitHub OAuth redirection
+- `test-utils.ts`: Utility functions for testing including:
+  - Creating test applications
+  - Creating test users
+  - Generating authentication tokens
+  - Cleaning up test data
+
+The e2e tests use a real database connection and create/delete test data automatically, ensuring a clean test environment for each test run.
+

+# Database Migrations
+
+This directory contains the migration system for the database. The migrations are generated using DrizzleORM and are stored in the `sql` subdirectory.
+
+## Directory Structure
+
+- `sql/` - Contains the generated SQL migration files
+- `generate-migrations.ts` - Script to generate migration files
+- `migrate.ts` - Script to run migrations
+- `README.md` - This file
+
+## How to Use
+
+### Generating Migrations
+
+To generate migrations based on changes to the schema, run:
+
+```bash
+npm run db:generate:ts
+```
+
+This will generate SQL migration files in the `sql` directory.
+
+### Running Migrations
+
+To run all pending migrations, run:
+
+```bash
+npm run db:migrate
+```
+
+### Generating and Running Migrations in One Step
+
+To generate and run migrations in one step, run:
+
+```bash
+npm run db:update
+```
+
+## Integration with NestJS
+
+The migrations are automatically run when the application starts. This is configured in the `DatabaseService` class in `src/database/database.service.ts`.
+
+## Migration Files
+
+Migration files are SQL files that contain the SQL statements to create, alter, or drop database objects. They are named with a timestamp and a description, e.g. `0000_lively_tiger_shark.sql`.
+
+## Configuration
+
+The migration system is configured in `drizzle.config.ts` at the root of the project. This file specifies:
+
+- The schema file to use for generating migrations
+- The output directory for migration files
+- The database dialect and credentials

-
-#### 2.2.2 Gestion du Workspace avec PNPM
-Le projet utilise PNPM pour la gestion du workspace et des packages. PNPM offre plusieurs avantages par rapport à d'autres gestionnaires de packages:
-
-- **Efficacité de stockage**: Utilise un stockage partagé pour éviter la duplication des packages
-- **Gestion de monorepo**: Facilite la gestion des dépendances entre les packages du monorepo
-- **Performance**: Installation et mise à jour des dépendances plus rapides
-- **Déterminisme**: Garantit que les mêmes dépendances sont installées de manière cohérente
-
-Exemples d'utilisation de PNPM dans le monorepo:
-
-```bash
-# Exécuter une commande dans un package spécifique
-pnpm --filter <package-name> <command>
-
-# Exemple : démarrer le frontend uniquement
-pnpm --filter web dev
-
-# Installer une dépendance dans un package spécifique
-pnpm --filter <package-name> add <dependency>
-
-# Installer une dépendance de développement dans un package spécifique
-pnpm --filter <package-name> add -D <dependency>
-```
-
-#### 2.2.3 Communication entre les Services
-- API REST pour les opérations CRUD standard
-- WebSockets via SocketIO pour les communications en temps réel
-- Authentification via JWT pour sécuriser les échanges
-
-#### 2.2.4 Architecture et Flux d'Interactions
-Le diagramme ci-dessous illustre les interactions entre les différents composants du système:

-##### 2.3.3.3 Stratégie d'Indexation
-Pour optimiser les performances des requêtes, les stratégies d'indexation suivantes seront mises en place:
-- Index primaires sur toutes les clés primaires (UUIDv7)
-- Index secondaires sur les clés étrangères pour accélérer les jointures
-- Index composites sur les champs fréquemment utilisés ensemble dans les requêtes
-- Index partiels pour les requêtes filtrées fréquentes
-- Index de texte pour les recherches sur les champs textuels (noms, descriptions)
-
-DrizzleORM facilite la définition de ces index directement dans le schéma avec une syntaxe déclarative:
-```typescript
-// Exemple de définition d'index avec DrizzleORM
-import { pgTable, uuid, varchar, timestamp, index } from 'drizzle-orm/pg-core';
-
-export const users = pgTable('users', {
-  id: uuid('id').primaryKey().defaultRandom(),
-  name: varchar('name', { length: 255 }),
-  githubId: varchar('githubId', { length: 50 }),
-  gdprTimestamp: timestamp('gdprTimestamp', { withTimezone: true }),
-}, (table) => {
-  return {
-    githubIdIdx: index('githubId_idx').on(table.githubId),
-    nameIdx: index('name_idx').on(table.name),
-  };
-});
-```
-
-##### 2.3.3.4 Optimisation des Formats de Données
-Les types de données PostgreSQL seront optimisés pour chaque cas d'usage:
-- Utilisation de `UUID` pour les identifiants (UUIDv7 pour l'ordre chronologique)
-- Type `JSONB` pour les données flexibles et semi-structurées
-- Types `ENUM` PostgreSQL natifs pour les valeurs fixes (genres, niveaux d'aisance)
-- Type `TEXT` avec contraintes pour les chaînes de caractères variables
-- Types `TIMESTAMP WITH TIME ZONE` pour les dates avec gestion des fuseaux horaires
-- Utilisation de `NUMERIC` pour les valeurs nécessitant une précision exacte
-
-Ces optimisations permettront d'améliorer les performances des requêtes, de réduire l'empreinte mémoire et d'assurer l'intégrité des données.
-
-##### 2.3.3.5 Modèle Simplifié pour Utilisateurs Non-Techniques
-Le diagramme ci-dessous présente une version simplifiée du modèle de données, conçue pour être facilement compréhensible par des personnes non-techniques:

+# Configuration CORS
+
+Ce document explique comment le Cross-Origin Resource Sharing (CORS) est configuré dans l'application.
+
+## Vue d'ensemble
+
+Le CORS est un mécanisme de sécurité qui permet aux serveurs de spécifier quels domaines peuvent accéder à leurs ressources. Cette configuration est essentielle pour sécuriser l'API tout en permettant au frontend de communiquer avec le backend.
+
+Dans notre application, nous avons configuré le CORS différemment pour les environnements de développement et de production :
+
+- **Environnement de développement** : Configuration permissive pour faciliter le développement
+- **Environnement de production** : Configuration restrictive pour sécuriser l'application
+
+## Configuration dans le Backend
+
+### Configuration HTTP (NestJS)
+
+La configuration CORS pour les requêtes HTTP est définie dans le fichier `main.ts` :
+
+```typescript
+// Configuration CORS selon l'environnement
+const environment = configService.get<string>('NODE_ENV', 'development');
+const frontendUrl = configService.get<string>('FRONTEND_URL', 'http://localhost:3001');
+
+if (environment === 'development') {
+  // En développement, on autorise toutes les origines avec credentials
+  app.enableCors({
+    origin: true,
+    methods: 'GET,HEAD,PUT,PATCH,POST,DELETE,OPTIONS',
+    credentials: true,
+  });
+  console.log('CORS configured for development environment (all origins allowed)');
+} else {
+  // En production, on restreint les origines autorisées
+  const allowedOrigins = [frontendUrl];
+  // Ajouter d'autres origines si nécessaire (ex: sous-domaines, CDN, etc.)
+  if (configService.get<string>('ADDITIONAL_CORS_ORIGINS')) {
+    allowedOrigins.push(...configService.get<string>('ADDITIONAL_CORS_ORIGINS').split(','));
+  }
+  
+  app.enableCors({
+    origin: (origin, callback) => {
+      // Permettre les requêtes sans origine (comme les appels d'API mobile)
+      if (!origin || allowedOrigins.includes(origin)) {
+        callback(null, true);
+      } else {
+        callback(new Error(`Origin ${origin} not allowed by CORS`));
+      }
+    },
+    methods: 'GET,HEAD,PUT,PATCH,POST,DELETE,OPTIONS',
+    credentials: true,
+    maxAge: 86400, // 24 heures de mise en cache des résultats preflight
+  });
+  console.log(`CORS configured for production environment with allowed origins: ${allowedOrigins.join(', ')}`);
+}
+```
+
+### Configuration WebSockets (Socket.IO)
+
+La configuration CORS pour les WebSockets est définie dans le décorateur `@WebSocketGateway` dans le fichier `websockets.gateway.ts` :
+
+```typescript
+@WebSocketGateway({
+  cors: {
+    origin: process.env.NODE_ENV === 'development' 
+      ? true 
+      : [
+          process.env.FRONTEND_URL || 'http://localhost:3001',
+          ...(process.env.ADDITIONAL_CORS_ORIGINS ? process.env.ADDITIONAL_CORS_ORIGINS.split(',') : [])
+        ],
+    credentials: true,
+  },
+})
+```
+
+## Variables d'environnement
+
+Les variables d'environnement suivantes sont utilisées pour configurer le CORS :
+
+- `NODE_ENV` : Détermine l'environnement (development ou production)
+- `FRONTEND_URL` : URL du frontend (par défaut : http://localhost:3001)
+- `ADDITIONAL_CORS_ORIGINS` : Liste d'origines supplémentaires autorisées en production (séparées par des virgules)
+
+Ces variables sont définies dans le fichier `.env` à la racine du projet backend.
+
+## Configuration dans le Frontend
+
+Le frontend est configuré pour envoyer des requêtes avec les credentials (cookies, en-têtes d'autorisation) :
+
+```typescript
+// Dans api.ts
+const fetchOptions: RequestInit = {
+  ...options,
+  headers,
+  credentials: 'include', // Include cookies for session management
+};
+
+// Dans socket-context.tsx
+const socketInstance = io(API_URL, {
+  withCredentials: true,
+  query: {
+    userId: user.id,
+  },
+});
+```
+
+## Modification de la configuration
+
+### Ajouter des origines autorisées en production
+
+Pour ajouter des origines autorisées en production, modifiez la variable `ADDITIONAL_CORS_ORIGINS` dans le fichier `.env` :
+
+```
+ADDITIONAL_CORS_ORIGINS=https://app2.example.com,https://app3.example.com
+```
+
+### Modifier la configuration CORS
+
+Pour modifier la configuration CORS, vous pouvez ajuster les paramètres dans les fichiers `main.ts` et `websockets.gateway.ts`.
+
+## Considérations de sécurité
+
+- En production, limitez les origines autorisées aux domaines de confiance
+- Utilisez HTTPS pour toutes les communications en production
+- Évitez d'utiliser `origin: '*'` en production, car cela ne permet pas l'envoi de credentials
+- Limitez les méthodes HTTP autorisées aux méthodes nécessaires
+- Utilisez le paramètre `maxAge` pour réduire le nombre de requêtes preflight

 ## Conclusion
 
-Le projet a bien avancé sur la structure de base et la définition du schéma de données, mais il reste encore un travail significatif à réaliser. Les prochaines étapes prioritaires devraient se concentrer sur l'authentification et les fonctionnalités de base pour avoir rapidement une version minimale fonctionnelle.
+Le projet est maintenant dans un état avancé avec une base solide et la plupart des fonctionnalités principales implémentées. Les points forts actuels du projet sont:
+
+1. **Architecture robuste**: Le backend NestJS et le frontend Next.js sont bien structurés, avec une séparation claire des responsabilités et une organisation modulaire.
+
+2. **Fonctionnalités principales complètes**: Toutes les fonctionnalités essentielles sont implémentées, incluant l'authentification, la gestion des projets, des personnes, des groupes et des tags.
+
+3. **Communication en temps réel**: L'intégration de Socket.IO est complète, permettant une collaboration en temps réel entre les utilisateurs, avec des notifications et des mises à jour instantanées.
+
+4. **Tests unitaires**: Le backend dispose d'une couverture de tests unitaires complète pour tous les services et contrôleurs, assurant la fiabilité du code.
+
+5. **Intégration frontend-backend**: L'intégration entre le frontend et le backend est presque complète, avec des appels API réels et une gestion appropriée des erreurs et des états de chargement.
+
+Cependant, plusieurs aspects importants restent à finaliser:
+
+1. **Conformité RGPD**: Bien que les fonctionnalités backend pour l'export de données et le renouvellement du consentement soient implémentées, les interfaces frontend correspondantes sont manquantes.
+
+2. **Sécurité**: Les améliorations de sécurité comme la validation des entrées et la protection CSRF ont été implémentées. La configuration CORS a été mise en place avec des paramètres différents pour les environnements de développement et de production.
+
+3. **Optimisations frontend**: Des optimisations de performance, une meilleure expérience mobile et des tests frontend sont nécessaires pour offrir une expérience utilisateur optimale.
+
+Les prochaines étapes prioritaires devraient se concentrer sur:
+1. Implémenter les interfaces frontend pour la conformité RGPD
+2. Optimiser les performances du frontend
+
+En suivant ces recommandations, le projet pourra atteindre un niveau de qualité production dans les 3-4 semaines à venir, offrant une application complète, sécurisée et conforme aux normes actuelles.

+# Frontend Implementation
+
+This document provides an overview of the frontend implementation for the "Application de Création de Groupes" project.
+
+## Architecture
+
+The frontend is built with Next.js 15 using the App Router architecture. It follows a component-based approach with a clear separation of concerns:
+
+- **app/**: Contains all the pages and layouts organized by route
+- **components/**: Reusable UI components
+- **lib/**: Utility functions, hooks, and services
+
+## Authentication Flow
+
+The application uses GitHub OAuth for authentication:
+
+1. User clicks "Login with GitHub" on the login page
+2. User is redirected to GitHub for authorization
+3. GitHub redirects back to our callback page with an authorization code
+4. The callback page exchanges the code for an access token
+5. User information is stored in the AuthContext and localStorage
+6. User is redirected to the dashboard or the original page they were trying to access
+
+### Authentication Components
+
+- **AuthProvider**: Context provider that manages authentication state
+- **AuthLoading**: Component that displays a loading screen during authentication checks
+- **useAuth**: Hook to access authentication state and methods
+
+## API Communication
+
+All API communication is centralized in the `lib/api.ts` file, which provides:
+
+- A base `fetchAPI` function with error handling and authentication
+- Specific API modules for different resources (auth, projects, persons, tags, groups)
+- Type-safe methods for all API operations
+
+## Protected Routes
+
+All authenticated routes are protected by:
+
+1. **Middleware**: Redirects unauthenticated users to the login page
+2. **AuthLoading**: Shows a loading screen during authentication checks
+3. **AuthContext**: Provides user information and authentication methods
+
+## Layout Structure
+
+The application uses a nested layout structure:
+
+- **RootLayout**: Provides global styles and the AuthProvider
+- **DashboardLayout**: Provides the sidebar navigation and user interface for authenticated pages
+- **AdminLayout**: Provides the admin interface for admin-only pages
+
+## Components
+
+### UI Components
+
+The application uses ShadcnUI for UI components, which provides:
+
+- A consistent design system
+- Accessible components
+- Dark mode support
+
+### Custom Components
+
+- **dashboard-layout.tsx**: Main layout for authenticated pages
+- **auth-loading.tsx**: Loading component for authentication checks
+- **admin-layout.tsx**: Layout for admin pages
+
+## Future Development
+
+### Adding New Pages
+
+1. Create a new directory in the `app/` folder
+2. Create a `page.tsx` file with your page content
+3. Create a `layout.tsx` file that uses the appropriate layout and AuthLoading component
+
+### Adding New API Endpoints
+
+1. Add new methods to the appropriate API module in `lib/api.ts`
+2. Use the methods in your components with the `useEffect` hook or event handlers
+
+### Adding New Features
+
+1. Create new components in the `components/` folder
+2. Use the components in your pages
+3. Add new API methods if needed
+
+## Best Practices
+
+- Use the AuthContext for authentication-related operations
+- Use the API service for all API communication
+- Wrap authenticated pages with the AuthLoading component
+- Use TypeScript for type safety
+- Follow the component-based architecture
