#### Définir un *décorateur d'opération de chemin*

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

* le chemin `/`
* en utilisant une <abbr title="une méthode GET HTTP">opération <code>get</code></abbr>

/// info | `@décorateur` Info

Cette syntaxe `@something` en Python est appelée un "décorateur".

Specifically, to see Uvicorn, Starlette and FastAPI compared together (among many other tools).

The simpler the problem solved by the tool, the better performance it will get. And most of the benchmarks don't test the additional features provided by the tool.

The hierarchy is like:

* **Uvicorn**: an ASGI server
    * **Starlette**: (uses Uvicorn) a web microframework
