* Strings (`str`) mit definierter minimaler und maximaler Länge.
    * Zahlen (`int`, `float`) mit Mindest- und Maximalwerten, usw.

* Validierung für mehr exotische Typen, wie:
    * URL.
    * E-Mail.
    * UUID.
    * ... und andere.

Die gesamte Validierung übernimmt das gut etablierte und robuste **Pydantic**.

### Sicherheit und Authentifizierung { #security-and-authentication }

Em muitos casos, sua aplicação pode precisar de configurações externas, por exemplo chaves secretas, credenciais de banco de dados, credenciais para serviços de e-mail, etc.

A maioria dessas configurações é variável (pode mudar), como URLs de banco de dados. E muitas podem ser sensíveis, como segredos.

Por esse motivo, é comum fornecê-las em variáveis de ambiente lidas pela aplicação.

    /** The key of the configuration. e.g. Administrator */
    String MAIL_FROM_NAME = "mail.from.name";

    /** The key of the configuration. e.g. root@localhost */
    String MAIL_FROM_ADDRESS = "mail.from.address";

    /** The key of the configuration. e.g.  */
    String MAIL_HOSTNAME = "mail.hostname";

    /** The key of the configuration. e.g.  */

Dort können Sie „Releases only“ auswählen.

Auf diese Weise erhalten Sie Benachrichtigungen (per E-Mail), wenn es ein neues Release (eine neue Version) von **FastAPI** mit Bugfixes und neuen Funktionen gibt.
