* 支持复杂的用户身份认证系统，**数据库连接**等等。
* **不依赖**数据库，前端等。但是和它们集成很简单。

### 无限制的“插件” { #unlimited-plug-ins }

或者说，导入并使用你需要的代码，而不需要它们。

任何集成都被设计得被易于使用（用依赖关系），你可以用和*路径操作*相同的结构和语法，在两行代码中为你的应用创建一个“插件”。

### 测试 { #tested }

* 100% <dfn title="自动测试的代码量">测试覆盖</dfn>。
* 代码库100% <dfn title="Python 类型注解，有了这个你的编辑器和外部工具可以给你更好的支持">类型注释</dfn>。
* 用于生产应用。

## Starlette 特性 { #starlette-features }

* 不與資料庫、前端等進行強制綁定，但能輕鬆整合它們。

### 無限制「擴充功能」 { #unlimited-plug-ins }

或者說，無需其他額外配置，直接導入並使用你所需要的程式碼。

任何整合都被設計得非常簡單易用（通過依賴注入），你只需用與*路徑操作*相同的結構和語法，用兩行程式碼就能為你的應用程式建立一個「擴充功能」。

### 測試 { #tested }

* 100% <dfn title="自動化測試所涵蓋的程式碼量">測試覆蓋率</dfn>。
* 100% <dfn title="Python 型別註解；有了它你的編輯器和外部工具可以提供更好的支援">型別註解</dfn>的程式碼庫。
* 已能夠在生產環境應用程式中使用。
