* Более продвинутые (но столь же простые) методы объявления **глубоко вложенных моделей JSON** (спасибо Pydantic).
* **GraphQL** интеграция с <a href="https://strawberry.rocks" class="external-link" target="_blank">Strawberry</a> и другими библиотеками.
* Множество дополнительных функций (благодаря Starlette), таких как:
    * **Веб-сокеты**
    * очень простые тесты на основе HTTPX и `pytest`

* Những kĩ thuật nâng cao hơn (nhưng tương đối dễ) để định nghĩa **JSON models lồng nhau** (cảm ơn Pydantic).
* Tích hợp **GraphQL** với <a href="https://strawberry.rocks" class="external-link" target="_blank">Strawberry</a> và các thư viện khác.
* Nhiều tính năng mở rộng (cảm ơn Starlette) như:
    * **WebSockets**
    * kiểm thử vô cùng dễ dàng dựa trên HTTPX và `pytest`
    * **CORS**

* Fortgeschrittenere (aber ebenso einfache) Techniken zur Deklaration **tief verschachtelter JSON-Modelle** (dank Pydantic).
* **GraphQL** Integration mit <a href="https://strawberry.rocks" class="external-link" target="_blank">Strawberry</a> und anderen Bibliotheken.
* Viele zusätzliche Funktionen (dank Starlette) wie:
    * **WebSockets**
    * extrem einfache Tests auf Basis von `httpx` und `pytest`

* **çox dərin JSON modellərini** müəyyən etmək üçün daha irəli səviyyə (lakin eyni dərəcədə asan) üsullar (Pydantic sayəsində).
* <a href="https://strawberry.rocks" class="external-link" target="_blank">Strawberry</a> və digər kitabxanalar ilə **GraphQL** inteqrasiyası.
* Digər əlavə xüsusiyyətlər (Starlette sayəsində):
    * **WebSockets**
    * HTTPX və `pytest` sayəsində çox asan testlər
