Dependencies are handled mainly with the special function `Depends()` that takes a callable.

Here is the reference for it and its parameters.

You can import it directly from `fastapi`:

```python
from fastapi import Depends
```

::: fastapi.Depends

## `Security()`

For many scenarios, you can handle security (authorization, authentication, etc.) with dependencies, using `Depends()`.

템플릿은 일반적으로 특정 설정과 함께 제공되지만, 유연하고 커스터마이징이 가능하게 디자인 되었습니다. 이 특성들은 여러분이 프로젝트의 요구사항에 맞춰 수정, 적용을 할 수 있게 해주고, 템플릿이 완벽한 시작점이 되게 해줍니다. 🏁

많은 초기 설정, 보안, 데이터베이스 및 일부 API 엔드포인트가 이미 준비되어 있으므로, 여러분은 이 템플릿을 (프로젝트를) 시작하는 데 사용할 수 있습니다.

## Full Stack FastAPI 템플릿 - 기술 스택과 기능들

Sie wird direkt in FastAPI importiert/inkludiert, sodass Sie sie von `fastapi` importieren können und vermeiden, versehentlich das alternative `BackgroundTask` (ohne das `s` am Ende) von `starlette.background` zu importieren.

## Plantilla Full Stack FastAPI - Tecnología y Funcionalidades

- ⚡ [**FastAPI**](https://fastapi.tiangolo.com) para la API del backend en Python.
    - 🧰 [SQLModel](https://sqlmodel.tiangolo.com) para las interacciones con bases de datos SQL en Python (ORM).

    * Eğer Starlette'i karşılaştırıyorsanız, Sanic, Flask, Django, vb. frameworkler (veya mikroframeworkler) ile karşılaştırın.
* **FastAPI**:
    * Starlette'in Uvicorn'u kullandığı ve ondan daha hızlı olamayacağı gibi, **FastAPI**'da Starlette'i kullanır, dolayısıyla ondan daha hızlı olamaz.

new_app = UnicornMiddleware(app, some_config="rainbow")
```

Pero FastAPI (en realidad Starlette) proporciona una forma más simple de hacerlo que asegura que los middlewares internos manejen errores del servidor y los controladores de excepciones personalizadas funcionen correctamente.

Para eso, usas `app.add_middleware()` (como en el ejemplo para CORS).

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()

## Múltiples Workers

Puedes iniciar múltiples workers con la opción de línea de comando `--workers`:

//// tab | `fastapi`

Si usas el comando `fastapi`:

<div class="termy">

```console
$ <pre> <font color="#4E9A06">fastapi</font> run --workers 4 <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

    * If you are comparing Starlette, compare it against Sanic, Flask, Django, etc. Web frameworks (or microframeworks).
* **FastAPI**:
    * The same way that Starlette uses Uvicorn and cannot be faster than it, **FastAPI** uses Starlette, so it cannot be faster than it.

/// info

The <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a> package is automatically installed with **FastAPI** when you run the `pip install "fastapi[standard]"` command.

However, if you use the `pip install fastapi` command, the `python-multipart` package is not included by default.
