!!! tip
    Keep in mind that if you return a response directly instead of using the `Response` parameter, FastAPI will return it directly.

    So, you will have to make sure your data is of the correct type. E.g. it is compatible with JSON, if you are returning a `JSONResponse`.

    And also that you are not sending any data that should have been filtered by a `response_model`.

## Características de Starlette

**FastAPI** está basado y es completamente compatible con <a href="https://www.starlette.io/" class="external-link" target="_blank"><strong>Starlette</strong></a>. Tanto así, que cualquier código de Starlette que tengas también funcionará.

    Exactly the same technical details as in [SQL (Relational) Databases](../tutorial/sql-databases.md#note){.internal-link target=_blank} apply.

### Make Peewee async-compatible `PeeweeConnectionState`

`swagger_ui_parameters` receives a dictionary with the configurations passed to Swagger UI directly.

FastAPI converts the configurations to **JSON** to make them compatible with JavaScript, as that's what Swagger UI needs.

## Disable Syntax Highlighting

For example, you could disable syntax highlighting in Swagger UI.

        * `Path`
        * `Query`
        * ...as these are compatible with the WebSockets protocol (e.g. `Body` is not).
    * [Updated documentation for WebSockets](https://fastapi.tiangolo.com/advanced/websockets/).
    * PR [#178](https://github.com/tiangolo/fastapi/pull/178) by [@jekirl](https://github.com/jekirl).

* Upgrade the compatible version of Pydantic to `0.26.0`.

## À propos de Pydantic

Pydantic inclut des tests pour **FastAPI** avec ses propres tests, ainsi les nouvelles versions de Pydantic (au-dessus
de `1.0.0`) sont toujours compatibles avec **FastAPI**.

Vous pouvez épingler Pydantic à toute version supérieure à `1.0.0` qui fonctionne pour vous et inférieure à `2.0.0`.

Par exemple :

```txt
pydantic>=1.2.0,<2.0.0

But don't worry, you can show it as you wish to your final users in the frontend.

And your database models can use any other names you want.

But for the login *path operation*, we need to use these names to be compatible with the spec (and be able to, for example, use the integrated API documentation system).

The spec also states that the `username` and `password` must be sent as form data (so, no JSON here).

### `scope`

il existe de nombreux outils compatibles.

Grâce à cela, **FastAPI** lui-même fournit une documentation alternative (utilisant ReDoc), qui peut être lue
sur <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a> :
