### 無制限の「プラグイン」 { #unlimited-plug-ins }

別の言い方をすれば、プラグインは不要で、必要なコードをインポートして使うだけです。

あらゆる統合は（依存関係を用いて）非常に簡単に使えるよう設計されており、*path operation* で使うのと同じ構造と構文で、2 行のコードでアプリケーション用の「プラグイン」を作れます。

### テスト済み { #tested }

* 100% の <dfn title="自動的にテストされるコードの量">テストカバレッジ</dfn>。
* 100% <dfn title="Python の型アノテーション。これにより、エディタや外部ツールからより良い支援が受けられます">型アノテーション付き</dfn>のコードベース。
* 本番アプリケーションで使用されています。

Esta é uma função Python.

Ela será chamada pelo **FastAPI** sempre que receber uma requisição para a URL "`/`" usando uma operação `GET`.

Neste caso, é uma função `async`.

Você também pode defini-la como uma função normal em vez de `async def`:
