### その他のユーティリティ関数 { #other-utility-functions }

あなたが直接呼び出すユーティリティ関数は、通常の `def` でも `async def` でも構いません。FastAPI はその呼び出し方に影響を与えません。

これは、FastAPI があなたの代わりに呼び出す関数 (すなわち *path operation 関数* と依存関係) とは対照的です。

ユーティリティ関数が `def` の通常関数であれば、(あなたのコードに書いたとおりに) 直接呼び出され、スレッドプールでは実行されません。関数が `async def` で作られている場合は、その関数を呼ぶときに `await` すべきです。

# Streaming

## Stream JSON Lines

To stream JSON Lines, declare the return type and use `yield` to return the data.

```python
@app.get("/items/stream")
async def stream_items() -> AsyncIterable[Item]:
    for item in items:
        yield item
```

## Server-Sent Events (SSE)

To stream Server-Sent Events, use `response_class=EventSourceResponse` and `yield` items from the endpoint.
