С **FastAPI** вы получаете все возможности **Starlette** (так как FastAPI — это всего лишь Starlette на стероидах):

* Серьёзно впечатляющая производительность. Это <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">один из самых быстрых фреймворков на Python, наравне с **NodeJS** и **Go**</a>.
* Поддержка **WebSocket**.
* Фоновые задачи в том же процессе.

    * Document better how to handle exceptions and use error handlers.
    * Include `RequestValidationError` and `WebSocketRequestValidationError` (this last one will be useful once [encode/starlette#527](https://github.com/encode/starlette/pull/527) or equivalent is merged).
    * New documentation about exceptions handlers:

            // Then: Should not throw exception
            assertDoesNotThrow(() -> handle.doSendFragment(new byte[10], 0, 10));
        }

        @Test
        @DisplayName("Should handle encode message operation")
        void testEncodeMessage() throws NdrException, DcerpcException {
            // Given: Mock message
            DcerpcMessage mockMessage = mock(DcerpcMessage.class);

                .replace(TRY_STATEMENT, "<% try{ %>")
                .replace(CACHE_AND_SESSION_INVALIDATE_STATEMENT, "<% }catch(Exception e){session.invalidate();} %>");
    }

    /**
     * Encode the JSP content.
     * @param value The value.
     * @return The encoded value.
     */
    public static String encodeJsp(final String value) {
        return value.replace("<% try{ %>", TRY_STATEMENT)

            dos.close();

            throw new CIFSException("Failed to encode mechList", e);

Mit **FastAPI** bekommen Sie alles von **Starlette** (da FastAPI nur Starlette auf Steroiden ist):

* Schwer beeindruckende Performanz. Es ist <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">eines der schnellsten Python-Frameworks, auf Augenhöhe mit **NodeJS** und **Go**</a>.
* **WebSocket**-Unterstützung.
* Hintergrundtasks im selben Prozess.

With **FastAPI** you get all of **Starlette**'s features (as FastAPI is just Starlette on steroids):

* Seriously impressive performance. It is <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">one of the fastest Python frameworks available, on par with **NodeJS** and **Go**</a>.
* **WebSocket** support.
* In-process background tasks.
