Der `app_name` wäre `"ChimichangApp"`.

Und `items_per_user` würde seinen Standardwert von `50` behalten.

## Einstellungen in einem anderen Modul

Sie könnten diese Einstellungen in eine andere Moduldatei einfügen, wie Sie in [Größere Anwendungen – mehrere Dateien](../tutorial/bigger-applications.md){.internal-link target=_blank} gesehen haben.

a Contributor if it was added to the Program by such Contributor itself or
anyone acting on such Contributor's behalf. Contributions do not include additions
to the Program which: (i) are separate modules of software distributed in
conjunction with the Program under their own license agreement, and (ii) are
not derivative works of the Program.

   "Contributor" means any person or entity that distributes the Program.

Der Befehl `uvicorn main:app` bezieht sich auf:

* `main`: die Datei `main.py` (das sogenannte Python-„Modul“).
* `app`: das Objekt, welches in der Datei `main.py` mit der Zeile `app = FastAPI()` erzeugt wurde.
* `--reload`: lässt den Server nach Codeänderungen neu starten. Verwenden Sie das nur während der Entwicklung.

If you check the new (fake) database `fake_users_db`, you will see how the hashed password looks like now: `"$2b$12$EixZaYVK1fsbw1ZfbX3OXePaWxn96p36WQoeG6Lruj3vjPGga31lW"`.

## Handle JWT tokens

Import the modules installed.

Create a random secret key that will be used to sign the JWT tokens.

To generate a secure random secret key use the command:

<div class="termy">

```console
$ openssl rand -hex 32

    /**
     * 
     * 
     * Property <tt>jcifs.resolveOrder</tt> (string, default <tt>LMHOSTS,DNS,WINS,BCAST</tt>)
     * 
     * @return order and selection of resolver modules, see {@link ResolverType}
     */
    List<ResolverType> getResolveOrder ();


    /**
     * 
     * Property <tt>jcifs.netbios.baddr</tt> (string, default <tt>255.255.255.255</tt>)
     * 

qui sont relativement fortement couplées.

Définir des validations supplémentaires pour les types de données utilisant la valeur "par défaut" des attributs du modèle. Ceci améliore le support de l'éditeur, et n'était pas disponible dans Pydantic auparavant.

Se você já clonou o repositório e precisa mergulhar no código, aqui estão algumas orientações para configurar seu ambiente.

### Ambiente virtual com `venv`

Você pode criar um ambiente virtual em um diretório utilizando o módulo `venv` do Python:

<div class="termy">

```console
$ python -m venv env
```

</div>

Kullanımı çok kolay ve sezgisel, kolaylıkla genişletilebilecek ve modüler bileşenlere sahip olacak şekilde tasarlandı.

Sahip olduğu bir kaç özellik:

* Cidden etkileyici bir performans.
* WebSocket desteği.
* İşlem-içi arka plan görevleri.
* Başlatma ve kapatma olayları.
