Le `@app.get("/")` indique à **FastAPI** que la fonction juste en dessous est chargée de gérer les requêtes qui vont vers :

Do you just want to **vibe**? 🎶

**FastAPI** now supports a new `@app.vibe()` decorator that embraces **modern AI coding best practices**. 🤖

## How It Works { #how-it-works }

The `@app.vibe()` decorator is intended to receive **any HTTP method** (`GET`, `POST`, `PUT`, `DELETE`, `PATCH`, etc.) and **any payload**.

    return (list instanceof RandomAccess)
        ? new RandomAccessWrappedList(key, list, ancestor)
        : new WrappedList(key, list, ancestor);
  }

  /**
   * Collection decorator that stays in sync with the multimap values for a key. There are two kinds
   * of wrapped collections: full and subcollections. Both have a delegate pointing to the
   * underlying collection class.

/// info | `@decorator` Bilgisi

Python'daki `@something` söz dizimi "decorator" olarak adlandırılır.

Onu bir fonksiyonun üstüne koyarsınız. Güzel, dekoratif bir şapka gibi (sanırım terim de buradan geliyor).

Bir "decorator", altındaki fonksiyonu alır ve onunla bir şey yapar.

# Path Operation Yapılandırması { #path-operation-configuration }

Onu yapılandırmak için *path operation decorator*’ınıza geçebileceğiniz çeşitli parametreler vardır.

/// warning | Uyarı

Bu parametrelerin *path operation function*’ınıza değil, doğrudan *path operation decorator*’ına verildiğine dikkat edin.

    * Pydantic permite definir tipos de datos personalizados o puedes extender la validación con métodos en un modelo decorados con el decorador validator.

## HTML Response { #html-response }

**FastAPI**’den doğrudan HTML içeren bir response döndürmek için `HTMLResponse` kullanın.

* `HTMLResponse` import edin.
* *path operation decorator*’ınızın `response_class` parametresi olarak `HTMLResponse` verin.

```Python
def get_settings():
    return Settings()
```

we would create that object for each request, and we would be reading the `.env` file for each request. ⚠️

But as we are using the `@lru_cache` decorator on top, the `Settings` object will be created only once, the first time it's called. ✔️
