咨询基于Nx的多语言机票预订系统单体仓库结构合理性

我正在构建一个机票预订网站，涵盖用户注册、认证、预订、选座等功能。技术栈包含两个异构API（.NET API负责航班搜索、预订及支付；JS API负责实时选座更新与重复航班搜索缓存层管理），前端采用NextJS+Tailwind组件。

我尝试用Nx搭建单体仓库，但对组织方式存疑。初始结构如下：

/monorepo-root
├── /apps                   # Contains minimal, app-specific setup
│   ├── /frontend           # Entry point for the frontend (Next.js)
│   ├── /api-js             # Node.js API with REST operations
│   ├── /api-dotnet         # .NET API REST
├── /libs                   # Reusable code
│   ├── /ui                 # Shared UI components
│   │   ├── /components     # Reusable UI elements like buttons, modals
│   │   └── /layouts        # Shared page layouts
│   ├── /utils              # Shared utilities and helper functions
        ├── /date           # Date manipulation helpers

每个API内部包含各自的类模型、控制器等。之后看到一段关于Nx结构的说明：

Nx has a concept of Apps and Libs. Apps can be seen as deployable artifacts and libs include most of the actual code and the business logic. It’s nevertheless not unusual, when first starting to work with Nx, to put a lot of code into your Apps and to use libs only for shared code. But when you are switching to a Nx Monorepo, you should try to structure your repository “the Nx way”. That means that you should put almost no code at all into your apps and have almost all the code located in your libs. Even code that won’t be shared between apps should be put into libs. That might seem a bit counter intuitive at first, but if you apply that structure it will help you keep your monorepo organized. Plus, that way you are well prepared if it becomes necessary for a lib to be shared or reused somewhere else in the future. If you use a consistent folder structure and naming strategy for your libs you will end up with a monorepo that’ll be a pleasure to work in.

请问以下调整后的结构是否符合Nx规范？

/monorepo-root
├── /apps
|     ├── api-dotnet
│     |   ├── Program.cs                 # Bootstrapping the app
│     |   ├── Startup.cs (optional)      # Additional app configuration if needed
│     |   ├── appsettings.json           # App-specific configuration
│     |   ├── All Visual Studio Created files and folders (.csproj, bin, obj, etc)
│     |
|     ├── api-js
|     |   ├── index.js
|
├── /libs                   
│   ├── /ui                 # Shared UI components
│   │   ├── /components     # Reusable UI elements like buttons, modals
│   │   └── /layouts        # Shared page layouts
│   ├── /utils              # Shared utilities and helper functions
|   |   ├── /date           # Date manipulation helpers
│   ├── /features           # App-specific features, organized by domain
│   │   ├── /auth           # Authentication logic (e.g., login, register)
│   │   ├── /flight-search  # Flight search feature logic
│   │   └── /profile        # User profile management
│   └── /data-access        # Data-related code like database models, services
│       ├── /frontend-api   # Frontend API services
│       ├── /api-js-models  # Models and services for the Node.js API
│       └── /api-dotnet     # Data-related logic for .NET

结论：调整后的结构完全符合Nx核心规范，是推荐的最佳实践 #

符合规范的核心原因

1. Apps层严格定位为可部署工件
   api-dotnet和api-js仅保留启动配置、项目文件等运行/部署必需的代码，没有任何业务逻辑，完美契合Nx中"Apps是部署单元，仅负责引导"的设计理念。

2. 核心逻辑全部下沉到Libs层

   • 按领域划分的features目录将业务逻辑从Apps中剥离，即使当前部分功能仅服务于单个应用，也放在Libs中，为未来跨应用复用提前做好了准备。
   • data-access按不同端拆分，清晰隔离各API/前端的数据层逻辑，同时保持在Libs中，完全遵循Nx"将几乎所有代码放在Libs"的建议。

3. 分层清晰，职责明确
   ui、utils、features、data-access四大类Libs分工明确，遵循了Nx倡导的一致命名和文件夹结构，能让团队快速定位代码，维护成本更低。

可优化的细节

• 给Libs添加命名空间前缀（如@flight-booking/ui、@flight-booking/features-auth），利用Nx的命名空间特性避免跨语言/跨端的命名冲突。
• 将features下的子功能拆分为独立Lib（如features-auth、features-flight-search），而非放在同一目录下，这样Nx的代码生成、依赖分析和构建缓存能更精准地工作。
• 前端Next.js应用也遵循相同原则：将页面组件、业务逻辑移到Libs（如features或专属pages Lib），让frontend App仅保留Next.js基础配置和路由入口。
