## Investigation

User Guide** (what you are reading right now).

It's designed so that you can build a complete application with just the **Tutorial - User Guide**, and then extend it in different ways, depending on your needs, using some of the additional ideas from the **Advanced User Guide**....

# How To - Recipes

Here you will see different recipes or "how to" guides for **several topics**.

Most of these ideas would be more or less **independent**, and in most cases you should only need to study them if they apply directly to **your project**.

If something seems interesting and useful to your project, go ahead and check it, but otherwise, you might probably just skip them.

!!! tip

usando la mayoría de las características de **FastAPI** con el conocimiento del [Tutorial - Guía de Usuario](../tutorial/index.md){.internal-link target=_blank} principal.

En las siguientes secciones se asume que lo has leído y conoces esas ideas principales....

=== "Python 3.8 non-Annotated"

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

    ```Python hl_lines="15"
    {!> ../../../docs_src/dependencies/tutorial012.py!}
    ```

And all the ideas in the section about [adding `dependencies` to the *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} still apply, but in this case, to all of the *path operations* in the app.

    * Uvicorn (used by Starlette and **FastAPI**)

!!! check "Inspired **FastAPI** to"
    Exist.

    The idea of declaring multiple things (data validation, serialization and documentation) with the same Python types, that at the same time provided great editor support, was something I considered a brilliant idea.

And the next sections assume you already read it, and assume that you know those main ideas.

## External Courses

!!! tip
    You could adopt ideas from the section about SQLAlchemy ORM ([SQL (Relational) Databases](../tutorial/sql-databases.md){.internal-link target=_blank}), like using utility functions to perform operations in the database, independent of your **FastAPI** code.

(lo que estas leyendo ahora mismo).

La guía esa diseñada para que puedas crear una aplicación completa con solo el **Tutorial - Guía de Usuario**, y luego extenderlo de diferentes maneras, según tus necesidades, utilizando algunas de las ideas adicionales de la **Guía Avanzada de Usuario**....

In the next chapters, I'll give you more **concrete recipes** to deploy FastAPI applications.

But for now, let's check these important **conceptual ideas**. These concepts also apply to any other type of web API. 💡

## Security - HTTPS

In the [previous chapter about HTTPS](https.md){.internal-link target=_blank} we learned about how HTTPS provides encryption for your API.
