It will include all the routes from that router as part of it.

/// note | Technical Details

It will actually internally create a *path operation* for each *path operation* that was declared in the `APIRouter`.

So, behind the scenes, it will actually work as if everything was the same single app.

You don't have to worry about performance when including routers.

### Funções de operação de rota { #path-operation-functions }

Quando você declara uma *função de operação de rota* com `def` normal ao invés de `async def`, ela é rodada em uma threadpool externa que é então aguardada, ao invés de ser chamada diretamente (já que ela bloquearia o servidor).

* Sécurité et authentification, y compris la prise en charge de **OAuth2** avec des **JWT tokens** et l'authentification **HTTP Basic**.
* Des techniques plus avancées (mais tout aussi faciles) pour déclarer des **modèles JSON profondément imbriqués** (grâce à Pydantic).
* Intégration **GraphQL** avec [Strawberry](https://strawberry.rocks) et d'autres bibliothèques.

Pour que `await` fonctionne, il doit être placé dans une fonction qui supporte l'asynchronicité. Pour que ça soit le cas, il faut déclarer cette dernière avec `async def` :

```Python hl_lines="1"
async def get_burgers(number: int):
    # Opérations asynchrones pour créer les burgers
    return burgers
```

... et non `def` :

                            // and catch here rather than have it return null
                            if (rGroup == null) {
                                // relocated dependency artifact is declared excluded, no need to add and recurse
                                // further
                                continue;
                            }

 *  New: Publish a [bill of materials (BOM)][bom] for OkHttp. Depend on this from Gradle or Maven to
    keep all of your OkHttp artifacts on the same version, even if they're declared via transitive
    dependencies. You can even omit versions when declaring other OkHttp dependencies.

    ```kotlin
    dependencies {
       api(platform("com.squareup.okhttp3:okhttp-bom:4.4.0"))

     * converter.apply(), anyway. If clients use only converter.convert(), then their nullness
     * checkers are unlikely to ever look at the annotations on this declaration.
     *
     * Historical note: At one point, we'd declared this method as accepting and returning nullable
     * values. For details on that, see earlier revisions of this file.

    return convert(a);
