Bir [virtual environment](../virtual-environments.md) oluşturduğunuzdan, onu etkinleştirdiğinizden ve ardından paketi kurduğunuzdan emin olun. Örneğin:

```console
$ pip install python-multipart
```

Bu özellik FastAPI `0.113.0` sürümünden itibaren desteklenmektedir. 🤓

/// note | 참고

일부 응답 코드(다음 섹션 참고)는 응답에 본문이 없다는 것을 나타냅니다.

FastAPI는 이를 알고 있으며, 응답 본문이 없다고 명시하는 OpenAPI 문서를 생성합니다.

만약 HTTP 상태 코드가 무엇인지 이미 알고 있다면, 다음 섹션으로 넘어가세요.

HTTP에서는 응답의 일부로 3자리 숫자 상태 코드를 보냅니다.

## Tests { #tests }

Vous devez vous assurer d'avoir des [tests](../tutorial/testing.md) pour votre application et de les exécuter en intégration continue (CI).

De cette façon, vous pouvez effectuer la mise à niveau et vous assurer que tout fonctionne toujours comme prévu.

Dans ce guide, vous apprendrez à générer un **SDK TypeScript** pour votre backend FastAPI.

## Générateurs de SDK open source { #open-source-sdk-generators }

Une option polyvalente est le [OpenAPI Generator](https://openapi-generator.tech/), qui prend en charge **de nombreux langages de programmation** et peut générer des SDK à partir de votre spécification OpenAPI.

    Client->>Client: Process Item 1
    App->>Client: Send Item 2
    App->>App: Produce Item 3
    Client->>Client: Process Item 2
    App->>Client: Send Item 3
    Client->>Client: Process Item 3
    Note over App: Keeps producing...
    Note over Client: Keeps consuming...
```

Incluso podría ser un stream infinito, donde sigues enviando datos.

## JSON Lines { #json-lines }

    Client->>Client: Process Item 1
    App->>Client: Send Item 2
    App->>App: Produce Item 3
    Client->>Client: Process Item 2
    App->>Client: Send Item 3
    Client->>Client: Process Item 3
    Note over App: Keeps producing...
    Note over Client: Keeps consuming...
```

It could even be an infinite stream, where you keep sending data.
