**FastAPI** は **ASGI** 標準に基づいているため、ASGI に対応した任意の **GraphQL** ライブラリを簡単に統合できます。

同じアプリケーション内で通常の FastAPI の *path operation* と GraphQL を組み合わせて使えます。

/// tip | 豆知識

**GraphQL** は非常に特定のユースケースを解決します。

一般的な **Web API** と比べると、**長所** と **短所** があります。

ご自身のユースケースで得られる **利点** が **欠点** を補うかどうかを評価してください。 🤓

## GraphQL ライブラリ { #graphql-libraries }

**ASGI** をサポートする **GraphQL** ライブラリの一部を以下に示します。**FastAPI** と組み合わせて使用できます:

        super.setUp(testInfo);
        themeHelper = new ThemeHelper();
        tempDir = Files.createTempDirectory("theme-test");
        Files.createDirectories(Paths.get("target", "fess", "WEB-INF", "view"));
        Files.createDirectories(Paths.get("target", "fess", "WEB-INF", "plugin"));
        Files.createDirectories(Paths.get("target", "fess", "images"));
        Files.createDirectories(Paths.get("target", "fess", "css"));

    private static String webConfigId;

    @BeforeAll
    protected static void initAll() {
        RestAssured.baseURI = getFessUrl();
        settingTestToken();

        // create and execute a web crawler
        createWebConfig();
        logger.info("WebConfig is created");
        refresh();
        webConfigId = getWebConfigIds(NAME_PREFIX).get(0);

        createJob();

    }

    @Test
    public void test_getArtifactFromFileName_complexName() {
        Artifact artifact = pluginHelper.getArtifactFromFileName(ArtifactType.DATA_STORE, "fess-ds-web-crawler-1.2.3-beta.jar");
        assertEquals("fess-ds-web-crawler", artifact.getName());
        assertEquals("1.2.3-beta", artifact.getVersion());
    }

    @Test
    public void test_getArtifactFromFileName_singleVersion() {

    inflater.close()

    assertFailsWith<Exception> {
      inflater.inflate("f240e30300".decodeHex())
    }
  }

  /**
   * Test for an [EOFException] caused by mishandling of fragmented buffers in web socket
   * compression. https://github.com/square/okhttp/issues/5965
   */
  @Test fun `inflate golden value in buffer that has been fragmented`() {
    val inflater = MessageInflater(false)

This is similar to [Stream JSON Lines](stream-json-lines.md), but uses the `text/event-stream` format, which is supported natively by browsers with the [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource).

## What are Server-Sent Events? { #what-are-server-sent-events }

SSE is a standard for streaming data from the server to the client over HTTP.

Job status can also be viewed in a browser by navigating to the YARN ResourceManager Web UI and clicking on job history server information.
