## **FastAPI** utilities

FastAPI provides several tools for each of these security schemes in the `fastapi.security` module that simplify using these security mechanisms.

In the next chapters you will see how to add security to your API using those tools provided by **FastAPI**.

    * Docker ile multi-stage yapı, böylece kodu derlemeniz, kaydetmeniz veya işlemeniz gerekmez.
    * Derleme zamanında Frontend testi (devre dışı bırakılabilir).
    * Mümkün olduğu kadar modüler yapılmıştır, bu nedenle kutudan çıktığı gibi çalışır, ancak Vue CLI ile yeniden oluşturabilir veya ihtiyaç duyduğunuz şekilde oluşturabilir ve istediğinizi yeniden kullanabilirsiniz.

// Alpine and some distros struggles with this - ipset CLI utilities support this, but
// the kernel can be out of sync with the CLI utility, leading to errors like:
//
// ipset v7.10: Argument `comment' is supported in the kernel module of the set type hash:ip
// starting from the revision 3 and you have installed revision 1 only.
// Your kernel is behind your ipset utility.
//
// This happens with kernels as recent as Fedora38, e.g: 6.4.11-200.fc38.aarch64

/// tip | Dica

A própria `JSONResponse` é uma subclasse de `Response`.

///

E quando você retorna uma `Response`, o **FastAPI** vai repassá-la diretamente.

Ele não vai fazer conversões de dados com modelos do Pydantic, não irá converter a tipagem de nenhum conteúdo, etc.

Isso te dá bastante flexibilidade. Você pode retornar qualquer tipo de dado, sobrescrever qualquer declaração e validação nos dados, etc.

The `app_name` would be `"ChimichangApp"`.

And the `items_per_user` would keep its default value of `50`.

## Settings in another module

You could put those settings in another module file as you saw in [Bigger Applications - Multiple Files](../tutorial/bigger-applications.md){.internal-link target=_blank}.

For example, you could have a file `config.py` with:

```Python

Remember that when you import `Query`, `Path`, and others from `fastapi`, those are actually functions that return special classes.

/// tip

Notice how each model's attribute with a type, default value and `Field` has the same structure as a *path operation function's* parameter, with `Field` instead of `Path`, `Query` and `Body`.
