* Headers.
    * Query parameters.
    * Cookies, etc.

Plus all the security features from Starlette (including **session cookies**).

All built as reusable tools and components that are easy to integrate with your systems, data stores, relational and NoSQL databases, etc.

### Dependency Injection

* Bazy danych, front end, itp. **bez kompromisów**, ale wciąż łatwe do integracji.

### Nieograniczone "wtyczki"

Lub ujmując to inaczej - brak potrzeby wtyczek. Importuj i używaj kod, który potrzebujesz.

Każda integracja została zaprojektowana tak, aby była tak prosta w użyciu (z zależnościami), że możesz utworzyć "wtyczkę" dla swojej aplikacji w 2 liniach kodu, używając tej samej struktury i składni, które są używane w *operacjach na ścieżce*.

/// check | "Inspired **FastAPI** to"

Adopt and use an open standard for API specifications, instead of a custom schema.

And integrate standards-based user interface tools:

* <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>

And you can use directly many well maintained and widely used packages like `passlib` and `PyJWT`, because **FastAPI** doesn't require any complex mechanisms to integrate external packages.

But it provides you the tools to simplify the process as much as possible without compromising flexibility, robustness, or security.

3. Essa declaração `yield from` informa a função para iterar sobre essa coisa nomeada de `file_like`. E então, para cada parte iterada, fornece essa parte como se viesse dessa função geradora (`iterfile`).

    Então, é uma função geradora que transfere o trabalho de "geração" para alguma outra coisa interna.

### Testes no seu editor

Se você quer usar os testes integrados em seu editor adicione `./docs_src` na sua variável `PYTHONPATH`.

Por exemplo, no VS Code você pode criar um arquivo `.env` com:

```env
PYTHONPATH=./docs_src

/// tip | "Dica"

Estamos usando um cabeçalho inventado para simplificar este exemplo.

Mas em casos reais, você obterá melhores resultados usando os [Utilitários de Segurança](security/index.md){.internal-link target=_blank} integrados.

## Outro módulo com `APIRouter`

Digamos que você também tenha os endpoints dedicados a manipular "itens" do seu aplicativo no módulo em `app/routers/items.py`.

Você tem *operações de rota* para:

            }
          }
          return multiplyFraction(result, numerator, denominator);
        }
    }
  }

  /** Returns (x * numerator / denominator), which is assumed to come out to an integral value. */
  static long multiplyFraction(long x, long numerator, long denominator) {
    if (x == 1) {
      return numerator / denominator;
    }
    long commonDivisor = gcd(x, denominator);

            }
          }
          return multiplyFraction(result, numerator, denominator);
        }
    }
  }

  /** Returns (x * numerator / denominator), which is assumed to come out to an integral value. */
  static long multiplyFraction(long x, long numerator, long denominator) {
    if (x == 1) {
      return numerator / denominator;
    }
    long commonDivisor = gcd(x, denominator);

Extensions API group): Kubernetes can schedule a service (such as a logging
agent) that runs one, and only one, pod per node.
     * TLS and L7 support (Ingress API (Beta) in the Extensions API group): Kubernetes
is now easier to integrate into custom networking environments by supporting
TLS for secure communication and L7 http-based traffic routing.
     * Graceful Node Shutdown (aka drain) - The new “kubectl drain” command gracefully
