Emin değilseniz, normal `def` kullanın.

---

Not: *path operasyon fonksiyonlarınızda* `def` ve `async def`'i ihtiyacınız kadar karıştırabilirsiniz, her birini sizin için en iyi seçenekle tanımlayın. FastAPI onlar için doğru olanı yapacaktır.

Yukarıdaki durumların herhangi birinde FastAPI yine de asenkron olarak çalışır ve son derece hızlıdır.

İkisi de eşdeğer ve temelde aynıdır; ancak "**optional**" kelimesi değerin isteğe bağlı olduğunu ima eder. Oysa aslında " `None` olabilir" demektir; değer isteğe bağlı olmasa ve hâlâ zorunlu olsa bile.

Bence `Union[SomeType, None]` ne demek istediğini daha açık anlatır.

Burada mesele sadece kelimeler ve isimler. Ancak bu kelimeler sizin ve ekip arkadaşlarınızın koda bakışını etkileyebilir.

Ce n'est bien sûr pas le frontend pour les utilisateurs finaux, mais c'est un excellent outil automatique pour documenter de manière interactive toute votre API.

Il peut être utilisé par l'équipe frontend (qui peut aussi être vous-même).

## FastAPI Cloud { #fastapi-cloud }

**[FastAPI Cloud](https://fastapicloud.com)** wurde vom selben Autor und Team hinter **FastAPI** entwickelt.

Es vereinfacht den Prozess des **Erstellens**, **Deployens** und **Zugreifens** auf eine API mit minimalem Aufwand.

Es bringt die gleiche **Developer-Experience** beim Erstellen von Apps mit FastAPI auch zum **Deployment** in der Cloud. 🎉

    @Inject
    public MojoExecutionScopeCoreModule() {
        super(new MojoExecutionScope());
    }

    @Override
    protected void configure() {
        super.configure();
        bind(MojoExecutionListener.class).toInstance(scope);

 * Instances of this interface retrieve and store data for the --resume / -r feature. This data is used to ensure newer

    yield ServerSentEvent(data={"progress": 50}, event="progress", id="2")
```

Use `raw_data` instead of `data` to send pre-formatted strings without JSON encoding:

```python
yield ServerSentEvent(raw_data="plain text line", event="log")
```

## Stream bytes

To stream bytes, declare a `response_class=` of `StreamingResponse` or a sub-class, and use `yield` to return the data.

```python
from fastapi import FastAPI
