* **GraphQL** integration with [Strawberry](https://strawberry.rocks) and other libraries.
* Many extra features (thanks to Starlette) as:
    * **WebSockets**
    * extremely easy tests based on HTTPX and `pytest`
    * **CORS**
    * **Cookie Sessions**
    * ...and more.

### Deploy your app (optional)

* 宣告**深度巢狀 JSON 模型**的進階（但同樣簡單）技巧（感謝 Pydantic）。
* 與 [Strawberry](https://strawberry.rocks) 及其他函式庫的 **GraphQL** 整合。
* 許多額外功能（感謝 Starlette），例如：
    * **WebSockets**
    * 基於 HTTPX 與 `pytest` 的極其簡單的測試
    * **CORS**
    * **Cookie Sessions**
    * ...以及更多。

* **深くネストされた JSON モデル**を宣言するための、より高度な（しかし同様に簡単な）手法（Pydantic のおかげです）。
* [Strawberry](https://strawberry.rocks) および他のライブラリによる **GraphQL** 統合。
* 以下のようなたくさんのおまけ機能（Starlette のおかげです）:
    * **WebSockets**
    * HTTPX と `pytest` に基づく極めて簡単なテスト
    * **CORS**
    * **Cookie Sessions**
    * ...などなど。
