* **PGAdmin** pour les bases de données PostgreSQL, facilement modifiable pour utiliser PHPMYAdmin ou MySQL.
* **Flower** pour la surveillance de tâches Celery.
* Équilibrage de charge entre le frontend et le backend avec **Traefik**, afin de pouvoir avoir les deux sur le même domaine, séparés par chemins, mais servis par différents conteneurs.

#### Define a *path operation decorator*

```Python hl_lines="6"
{!../../../docs_src/first_steps/tutorial001.py!}
```

The `@app.get("/")` tells **FastAPI** that the function right below is in charge of handling requests that go to:

* the path `/`
* using a <abbr title="an HTTP GET method"><code>get</code> operation</abbr>

!!! info "`@decorator` Info"

app.include_router(
    router_b_override, prefix="/b", default_response_class=PlainTextResponse
)


client = TestClient(app)

json_type = "application/json"
text_type = "text/plain; charset=utf-8"
html_type = "text/html; charset=utf-8"
override_type = "application/x-override"


def test_app():
    with client:
        response = client.get("/")
    assert response.json() == {"msg": "Hello World"}

We also saw that HTTPS is normally provided by a component **external** to your application server, a **TLS Termination Proxy**.

And there has to be something in charge of **renewing the HTTPS certificates**, it could be the same component or it could be something different.

### Example Tools for HTTPS

Some of the tools you could use as a TLS Termination Proxy are:

* Traefik

    assert response.headers["content-type"] == "text/html; charset=utf-8"
    assert "window.opener.swaggerUIRedirectOauth2" in response.text


def test_redoc():
    response = client.get("/redoc")
    assert response.status_code == 200, response.text
    assert response.headers["content-type"] == "text/html; charset=utf-8"
    assert "redoc@next" in response.text

Avec **FastAPI** vous pouvez bénéficier de la concurrence qui est très courante en développement web (c'est l'attrait principal de NodeJS).

Mais vous pouvez aussi profiter du parallélisme et multiprocessing afin de gérer des charges **CPU bound** qui sont récurrentes dans les systèmes de *Machine Learning*.

FastAPI (eigentlich Starlette) fügt automatisch einen Content-Length-Header ein. Außerdem wird es einen Content-Type-Header einfügen, der auf dem media_type basiert, und für Texttypen einen Zeichensatz (charset) anfügen.

```Python hl_lines="1  18"
{!../../../docs_src/response_directly/tutorial002.py!}
```

### `HTMLResponse`

* `status_code` - `int` のHTTPステータスコード。
* `headers` - 文字列の `dict` 。
* `media_type` - メディアタイプを示す `str` 。例えば `"text/html"` 。

FastAPI (実際にはStarlette) は自動的にContent-Lengthヘッダーを含みます。また、media_typeに基づいたContent-Typeヘッダーを含み、テキストタイプのためにcharsetを追加します。

```Python hl_lines="1  18"
{!../../../docs_src/response_directly/tutorial002.py!}
```

### `HTMLResponse`

上で読んだように、テキストやバイトを受け取り、HTMLレスポンスを返します。

### `PlainTextResponse`
