Ключові особливості:

* **Швидкий**: Дуже висока продуктивність, на рівні з **NodeJS** та **Go** (завдяки Starlette та Pydantic). [Один із найшвидших фреймворків](#performance).

* **Швидке написання коду**: Пришвидшує розробку функціоналу приблизно на 200%-300%. *

If you go to the `/docs` API UI, you will see that it is now updated, and it won't expect to receive the `id` from the client when creating a hero, etc.

For any non-trivial change, we need to be able to answer these questions:

* Why is this change done? What's the use case?
* For user facing features, what will the API look like?
* What test cases should it have? What could go wrong?
* How will it roughly be implemented? We'll happily provide code pointers to save you time.

We may ask you to answer these questions directly in the GitHub issue or (for large changes) in a shared Google Doc.

In most setups this is sufficient to heal the content after drive replacements. Setting `max_sleep` to a *lower* value and setting `max_io` to a *higher* value would make heal go faster.

* Zeer indrukwekkende prestaties. Het is <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">een van de snelste Python frameworks, vergelijkbaar met **NodeJS** en **Go**</a>.
* **WebSocket** ondersteuning.
* Taken in de achtergrond tijdens het proces.
* Opstart- en afsluit events.
* Test client gebouwd op HTTPX.
* **CORS**, GZip, Statische bestanden, Streaming reacties.

* Desempenho realmente impressionante. É <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">um dos _frameworks_ Python disponíveis mais rápidos, a par com o **NodeJS** e **Go**</a>.
* Suporte a **WebSocket**.
* Suporte a **GraphQL**.
* Tarefas em processo _background_.
* Eventos na inicialização e encerramento.
* Cliente de testes construído sobre HTTPX.
