* String (`str`) fields, defining min and max lengths.
    * Numbers (`int`, `float`) with min and max values, etc.

* Validation for more exotic types, like:
    * URL.
    * Email.
    * UUID.
    * ...and others.

All the validation is handled by the well-established and robust **Pydantic**.

# Settings and Environment Variables { #settings-and-environment-variables }

In many cases your application could need some external settings or configurations, for example secret keys, database credentials, credentials for email services, etc.

Most of these settings are variable (can change), like database URLs. And many could be sensitive, like secrets.

For this reason it's common to provide them in environment variables that are read by the application.

/// tip

Во многих случаях вашему приложению могут понадобиться внешние настройки или конфигурации, например секретные ключи, учетные данные для базы данных, учетные данные для email‑сервисов и т.д.

Большинство таких настроек являются изменяемыми (могут меняться), например URL базы данных. И многие из них могут быть «чувствительными», например секреты.
