🎯 Domain-Driven Design Implementation

Domain Entities

• User Entity: Complete user management with roles, permissions, and status
• Product Entity: Product catalog with inventory, pricing, and ratings
• Value Objects: Immutable objects for IDs, emails, prices, etc.
• Domain Services: Business logic encapsulation

Repository Pattern

• Interface-based contracts for data access
• Mock implementations for development
• Search and filtering capabilities
• Bulk operations support

Service Layer

• Business logic separation
• Transaction management patterns
• Error handling and validation
• Audit trail support

🔧 Adding New Features (DDD Way)

1. Create Domain Entity

// src/domain/entities/Order.ts
export interface Order {
  id: OrderId
  customer: Customer
  items: OrderItem[]
  status: OrderStatus
  total: Money
  createdAt: Date
}

2. Define Repository Interface

// src/domain/repositories/IOrderRepository.ts
export interface IOrderRepository {
  findById(id: OrderId): Promise<Order | null>
  save(order: Order): Promise<Order>
  findByCustomer(customerId: string): Promise<Order[]>
}

3. Create Service Interface

// src/domain/services/IOrderService.ts
export interface IOrderService {
  createOrder(request: CreateOrderRequest): Promise<Order>
  processOrder(orderId: string): Promise<Order>
  cancelOrder(orderId: string, reason: string): Promise<Order>
}

4. Implement Repository

// src/infrastructure/repositories/MockOrderRepository.ts
export class MockOrderRepository implements IOrderRepository {
  async findById(id: OrderId): Promise<Order | null> {
    // Implementation
  }
}

5. Implement Service

// src/application/services/OrderService.ts
export class OrderService implements IOrderService {
  constructor(private orderRepository: IOrderRepository) {}
  
  async createOrder(request: CreateOrderRequest): Promise<Order> {
    // Business logic implementation
  }
}

6. Add Route and Page

// src/router/index.ts
{
  path: '/orders',
  name: 'Orders',
  component: () => import('@/pages/OrdersPage.vue')
}
