Module Configuration

{
  "source": ".",
  "output": "container.gen.ts",
  "exclude": ["**/*.test.ts", "**/*.spec.ts"],
  "verbose": true,
  "modules": {
    "UserModule": ["user/**"],
    "TodoModule": ["todo/**"]
  }
}

Cross-Module Dependencies

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

  async createTodo(title: string, userId: string): Promise<Todo> {
    const user = await this.userRepository.findById(userId);
    if (!user) {
      throw new Error('User not found');
    }

    return await this.todoRepository.create(title, userId);
  }
}

Usage

import { container } from './container.gen';

const userService = container.userModule.UserService;
const user = await userService.createUser('John Doe', 'john@example.com');

const todoService = container.todoModule.TodoService;
const todo = await todoService.createTodo('Learn modules', user.id);
