**FastAPI** bietet ein praktisches Werkzeug zur Strukturierung Ihrer Anwendung bei gleichzeitiger Wahrung der Flexibilität.

Wenn Sie von Flask kommen, wäre dies das Äquivalent zu Flasks Blueprints.

## Eine Beispiel-Dateistruktur { #an-example-file-structure }

Nehmen wir an, Sie haben eine Dateistruktur wie diese:

```
.
├── app
│   ├── __init__.py

    private transient @Nullable Object[] keys;
    private transient @Nullable Object[] values;
    private final Comparator<? super K> comparator;

    /**
     * Creates a new builder. The returned builder is equivalent to the builder generated by {@link
     * ImmutableSortedMap#orderedBy}.
     */
    public Builder(Comparator<? super K> comparator) {
      this(comparator, ImmutableCollection.Builder.DEFAULT_INITIAL_CAPACITY);

La forma en que lo usas es muy sencilla. Por ejemplo, para hacer un `GET` request, escribirías:

```Python
response = requests.get("http://example.com/some/url")
```

La operación de path equivalente en FastAPI podría verse como:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

Mira las similitudes entre `requests.get(...)` y `@app.get(...)`.

### Mémoire du serveur { #server-memory }

Ainda assim, a experiência final não foi a melhor. 😞

Essa seria o equivalente paralelo à história dos hambúrgueres. 🍔

Para um exemplo "mais real", imagine um banco.

Até recentemente, a maioria dos bancos tinham muitos caixas 👨‍💼👨‍💼👨‍💼👨‍💼 e uma grande fila 🕙🕙🕙🕙🕙🕙🕙🕙.

### Memória do servidor { #server-memory }

Et pourtant l'expérience finale n'est pas meilleure 😞.

C'est donc l'histoire équivalente parallèle pour les burgers 🍔.

Pour un exemple plus courant dans la « vie réelle », imaginez une banque.
