This tells Traefik to listen on port 9999 and to use another file `routes.toml`.

/// tip

We are using port 9999 instead of the standard HTTP port 80 so that you don't have to run it with admin (`sudo`) privileges.

///

Now create that other file `routes.toml`:

```TOML hl_lines="5  12  20"
[http]
  [http.middlewares]

It is a project from the Linux Foundation. It provides **HTTPS certificates for free**, in an automated way. These certificates use all the standard cryptographic security, and are short-lived (about 3 months), so the **security is actually better** because of their reduced lifespan.

The domains are securely verified and the certificates are generated automatically. This also allows automating the renewal of these certificates.

FastAPI'da opsiyonel olmasına rağmen, daha çok header'lar, çerezler ve alternatif durum kodları belirlemede kullanılıyor.

### <a href="https://moltenframework.com/" class="external-link" target="_blank">Molten</a>

**FastAPI**'ı geliştirmenin ilk aşamalarında Molten'ı keşfettim. Pek çok ortak fikrimiz vardı:

* Python'daki tip belirteçlerini baz alıyordu.
* Bunlara bağlı olarak veri doğrulaması ve dökümantasyon sağlıyordu.

    * FastAPIを使用することで、開発時間、バグ、コード行数を節約でき、使用しない場合 (あなたが全ての機能を実装し直した場合) と同じかそれ以上のパフォーマンスを得られます。

Input language:

The assembler uses mostly the same syntax for all architectures,
the main variation having to do with addressing modes. Input is
run through a simplified C preprocessor that implements #include,
#define, #ifdef/endif, but not #if or ##.

## Renvoyer une `Response` personnalisée

L'exemple ci-dessus montre toutes les parties dont vous avez besoin, mais il n'est pas encore très utile, car vous auriez pu retourner l'`item` directement, et **FastAPI** l'aurait mis dans une `JSONResponse` pour vous, en le convertissant en `dict`, etc. Tout cela par défaut.
