# Plan d'implémentation : Portail Transporteur avec Authentification

## 📋 Vue d'ensemble

Ce document détaille l'implémentation complète d'un portail transporteur B2B avec :
- ✅ Création automatique de compte au premier clic sur le lien email
- 📊 Dashboard avec statistiques et historique
- 📄 Gestion et téléchargement des documents par booking
- 🔐 Authentification sécurisée JWT
- 👤 Gestion du profil transporteur

---

## 🏗️ Architecture Technique

### Stack Technologique
- **Backend** : NestJS + TypeORM + PostgreSQL
- **Frontend** : Next.js 14 + TanStack Query + Zustand
- **Auth** : JWT (même système que les utilisateurs clients)
- **Storage** : MinIO/S3 pour les documents
- **Email** : Nodemailer pour les notifications

### Modèle de données

### Étape 4.3 : Modifier le Controller `CsvBookingsController`

Mettre à jour les méthodes `acceptBooking` et `rejectBooking` pour créer le compte transporteur.

**Fichier** : `apps/backend/src/application/controllers/csv-bookings.controller.ts`

```typescript
// Dans la méthode acceptBooking (ligne 258), REMPLACER par :

  // 1. Accepter le booking
  const booking = await this.csvBookingService.acceptBooking(token);

  // 2. Créer le compte transporteur si nécessaire
  const { carrierId, userId, isNewAccount, temporaryPassword } =
    await this.carrierAuthService.createCarrierAccountIfNotExists(
      booking.carrierEmail,
      booking.carrierName
    );

  // 3. Lier le booking au transporteur
  await this.csvBookingService.linkBookingToCarrier(booking.id, carrierId);

  // 4. Générer un token auto-login
  const autoLoginToken = await this.carrierAuthService.generateAutoLoginToken(userId, carrierId);

  // 5. Rediriger vers la page de confirmation avec auto-login
  const frontendUrl = process.env.APP_URL || 'http://localhost:3000';
  res.redirect(
    HttpStatus.FOUND,
    `${frontendUrl}/carrier/confirmed?token=${autoLoginToken}&action=accepted&bookingId=${booking.id}&new=${isNewAccount}`
  );
}

// Dans la méthode rejectBooking (ligne 297), REMPLACER par :

async rejectBooking(
  @Param('token') token: string,
  @Query('reason') reason: string,
  @Res() res: Response
): Promise<void> {
  // 1. Rejeter le booking
  const booking = await this.csvBookingService.rejectBooking(token, reason);

  // 2. Créer le compte transporteur si nécessaire
  const { carrierId, userId, isNewAccount, temporaryPassword } =
    await this.carrierAuthService.createCarrierAccountIfNotExists(
      booking.carrierEmail,
      booking.carrierName
    );

  // 3. Lier le booking au transporteur
  await this.csvBookingService.linkBookingToCarrier(booking.id, carrierId);

  // 4. Générer un token auto-login
  const autoLoginToken = await this.carrierAuthService.generateAutoLoginToken(userId, carrierId);

  // 5. Rediriger vers la page de confirmation avec auto-login
