"_If you're looking to learn one **modern framework** for building REST APIs, check out **FastAPI** [...] It's fast, easy to use and easy to learn [...]_"

"_We've switched over to **FastAPI** for our **APIs** [...] I think you'll like it [...]_"

**Typer** es el hermano menor de FastAPI.  La intención es que sea el **FastAPI de las CLIs**. ⌨️ 🚀

## Requisitos

FastAPI está sobre los hombros de gigantes:

* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> para las partes web.
* <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> para las partes de datos.

## Instalación

=== "Python 3.8+ non-Annotated"

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python
    commons: CommonQueryParams = Depends(CommonQueryParams)
    ```

The last `CommonQueryParams`, in:

```Python
... Depends(CommonQueryParams)
```

...is what **FastAPI** will actually use to know what is the dependency.

Docker and similar tools also use an **internal cache** when building the image, if a file hasn't changed since the last time building the container image, then it will **re-use the same layer** created the last time, instead of copying the file again and creating a new layer from scratch.

    ```Python hl_lines="2  5-8  11"
    {!> ../../../docs_src/settings/tutorial001_pv1.py!}
    ```

!!! tip
    If you want something quick to copy and paste, don't use this example, use the last one below.

!!! tip
    Also notice that there are `response_models` that have standard Python types like `List[schemas.Item]`.

    But as the content/parameter of that `List` is a Pydantic *model* with `orm_mode`, the data will be retrieved and returned to the client as normally, without problems.

### About `def` vs `async def`

Da diese Komponente die **Last** an Requests aufnehmen und diese (hoffentlich) **ausgewogen** auf die Worker verteilen würde, wird sie üblicherweise auch **Load Balancer** – Lastverteiler – genannt.
