In this guide, you'll learn how to generate a **TypeScript SDK** for your FastAPI backend.

## Open Source SDK Generators { #open-source-sdk-generators }

        // Arrange
        SmbPipeOutputStream out = newStream();
        CIFSException boom = new CIFSException("open-fail");
        when(handle.ensureOpen()).thenThrow(boom);

        // Act + Assert
        CIFSException ex = assertThrows(CIFSException.class, out::ensureOpen);
        assertEquals("open-fail", ex.getMessage());
        verify(handle, times(1)).ensureOpen();
    }

Você pode configurar alguns <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration/" class="external-link" target="_blank">parâmetros extras da UI do Swagger</a>.

Para configurá-los, passe o argumento `swagger_ui_parameters` ao criar o objeto da aplicação `FastAPI()` ou para a função `get_swagger_ui_html()`.

		// provide any DriveOPTimeout() function, as that is not
		// useful over persistent connections.
		Dialer: grid.ConnectWS(

			newCachedAuthToken(),

여기서, `shutdown` 이벤트 핸들러 함수는 `"Application shutdown"`이라는 텍스트를 `log.txt` 파일에 기록합니다.

/// info | 정보

`open()` 함수에서 `mode="a"`는 "추가"를 의미하므로, 파일에 있는 기존 내용은 덮어쓰지 않고 새로운 줄이 추가됩니다.

///

/// tip | 팁

이 경우, 우리는 표준 파이썬 `open()` 함수를 사용하여 파일과 상호작용하고 있습니다.

따라서 I/O(입출력) 작업이 포함되어 있어 디스크에 기록되는 것을 "기다리는" 과정이 필요합니다.

하지만 `open()`은 `async`와 `await`를 사용하지 않습니다.

그래서 우리는 이벤트 핸들러 함수를 `async def` 대신 일반 `def`로 선언합니다.
