**FastAPI** ile **Starlette**’in tüm özelliklerini elde edersiniz (FastAPI, steroid basılmış Starlette gibidir):

* Cidden etkileyici performans. [Mevcut en hızlı Python frameworklerinden biridir; **NodeJS** ve **Go** ile aynı seviyededir](https://github.com/encode/starlette#performance).
* **WebSocket** desteği.
* Süreç içi arka plan görevleri.
* Başlatma ve kapatma olayları.
* HTTPX üzerine kurulu test istemcisi.

    void testVariousStatusCodes(int status) {
        response.setStatusForTest(status);
        assertEquals(status, response.getErrorCode());
    }

    void resolveSids_allowsCertainRetvals_noThrow(int ret) throws Exception {
        SIDCacheImpl cache = new SIDCacheImpl(mock(CIFSContext.class));
        DcerpcHandle handle = mock(DcerpcHandle.class);

Con **FastAPI** obtienes todas las funcionalidades de **Starlette** (ya que FastAPI es simplemente Starlette potenciado):

* Rendimiento seriamente impresionante. Es [uno de los frameworks de Python más rápidos disponibles, a la par de **NodeJS** y **Go**](https://github.com/encode/starlette#performance).
* Soporte para **WebSocket**.
* Tareas en segundo plano en el mismo proceso.
* Eventos de inicio y apagado.
* Cliente de prueba basado en HTTPX.

    @Test
    @DisplayName("Should test isErrorResponseStatus with various status codes")
    void testIsErrorResponseStatus() throws Exception {
        // Test with NT_STATUS_NOTIFY_ENUM_DIR - should not be error
        setStatus(response, NtStatus.NT_STATUS_NOTIFY_ENUM_DIR);

通过 **FastAPI** 你可以获得所有 **Starlette** 的特性（FastAPI 就像加强版的 Starlette）：

* 令人惊叹的性能。它是[Python 可用的最快的框架之一，和 **NodeJS** 及 **Go** 相当](https://github.com/encode/starlette#performance)。
* **支持 WebSocket**。
* 进程内后台任务。
* Startup 和 shutdown 事件。
* 测试客户端基于 HTTPX。
* **CORS**、GZip、静态文件、流响应。
* 支持 **Session 和 Cookie**。
* 100% 测试覆盖率。
