  create(title: string, description: string): Promise<Todo>;
  update(id: string, updates: Partial<Todo>): Promise<Todo | null>;
  delete(id: string): Promise<boolean>;
}

Service Layer

export class TodoService implements ITodoService {
  constructor(private todoRepository: ITodoRepository) {}

  async createTodo(data: { title: string; description: string }): Promise<Todo> {
    return await this.todoRepository.create(data.title, data.description);
  }
}
