It is the recommended server for Starlette and **FastAPI**.

!!! check "**FastAPI** recommends it as"
    The main web server to run **FastAPI** applications.

    You can combine it with Gunicorn, to have an asynchronous multi-process server.

    Check more details in the [Deployment](deployment/index.md){.internal-link target=_blank} section.

## Benchmarks and speed

But once you know the basic information of **HTTPS for developers** you can easily combine and configure different tools to help you manage everything in a simple way.

La documentation sera donc mise à jour automatiquement pour autoriser plusieurs valeurs :

### Combiner liste de paramètres et valeurs par défaut

Et l'on peut aussi définir une liste de valeurs par défaut si aucune n'est fournie :

```Python hl_lines="9"
{!../../../docs_src/query_params_str_validations/tutorial012.py!}

$ python ./scripts/docs.py build-all

Building docs for: en
Building docs for: es
Successfully built docs for: es
```

</div>

This builds all those independent MkDocs sites for each language, combines them, and generates the final output at `./site/`.

Then you can serve that with the command `serve`:

<div class="termy">

```console
// Use the command "serve" after running "build-all"

When the `with` block finishes, it makes sure to close the file, even if there were exceptions.

When you create a dependency with `yield`, **FastAPI** will internally create a context manager for it, and combine it with some other related tools.

### Using context managers in dependencies with `yield`

!!! warning
    This is, more or less, an "advanced" idea.

Ensuite, il construit tous ces sites MkDocs indépendants pour chaque langue, les combine, et génère le résultat final à `./site/`.

Ensuite, vous pouvez servir cela avec le commandement `serve`:

<div class="termy">

```console
// Use the command "serve" after running "build-all"

Então ele constrói todos aqueles _sites_ independentes MkDocs para cada linguagem, combina eles, e gera a saída final em `./site/`.

Então você poderá "servir" eles com o comando `serve`:

<div class="termy">

```console
// Use o comando "serve" após rodar "build-all"

### Import `FastAPI`

You import and create a `FastAPI` class as normally.

And we can even declare [global dependencies](dependencies/global-dependencies.md){.internal-link target=_blank} that will be combined with the dependencies for each `APIRouter`:

```Python hl_lines="1  3  7" title="app/main.py"
{!../../../docs_src/bigger_applications/app/main.py!}
```

### Import the `APIRouter`

## _Cluster_ de Docker Swarm Mode com Traefik e HTTPS

* <a href="https://hub.docker.com/_/redis" class="external-link" target="_blank">Redis</a>, etc.

By using a pre-made container image it's very easy to **combine** and use different tools. For example, to try out a new database. In most cases, you can use the **official images**, and just configure them with environment variables.
