E pronto.

**2 linhas**.

E com a mesma forma e estrutura de todas as suas *funções de operação de rota*.

Você pode pensar nela como uma *função de operação de rota* sem o "decorador" (sem a linha `@app.get("/some-path")`).

E com qualquer retorno que você desejar.

Neste caso, a dependência espera por:

* Um parâmetro de consulta opcional `q` do tipo `str`.

* **Editör desteği**.
* **Tip kontrolleri**.

...ve **FastAPI** aynı bildirimleri şunlar için de kullanır:

* **Gereksinimleri tanımlamak**: request path parameters, query parameters, headers, bodies, bağımlılıklar (dependencies), vb.
* **Veriyi dönüştürmek**: request'ten gerekli tipe.
* **Veriyi doğrulamak**: her request'ten gelen veriyi:

With **FastAPI** you declare parameters with type hints and you get:

* **Editor support**.
* **Type checks**.

...and **FastAPI** uses the same declarations to:

* **Define requirements**: from request path parameters, query parameters, headers, bodies, dependencies, etc.
* **Convert data**: from the request to the required type.
* **Validate data**: coming from each request:

We'll discuss the `@lru_cache` in a bit.

For now you can assume `get_settings()` is a normal function.

///

And then we can require it from the *path operation function* as a dependency and use it anywhere we need it.
