* 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.

### 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

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.

/// 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.
