Bununla birlikte, code type’lar açısından doğru olduğu için editörler ve mypy araç desteği verir; ayrıca FastAPI’den veri filtrelemeyi de alırız.

Bu nasıl çalışıyor? Bir bakalım. 🤓

### Type Annotations ve Araç Desteği { #type-annotations-and-tooling }

* [`pydantic-settings`](https://docs.pydantic.dev/latest/usage/pydantic_settings/) - ayar yönetimi için.
* [`pydantic-extra-types`](https://docs.pydantic.dev/latest/usage/types/extra_types/extra_types/) - Pydantic ile kullanılacak ek type'lar için.

Ek opsiyonel FastAPI bağımlılıkları:

* [`orjson`](https://github.com/ijl/orjson) - `ORJSONResponse` kullanmak istiyorsanız gereklidir.
