/// warning | Attention

Lorsque vous renvoyez une `Response` directement, comme dans l'exemple ci-dessus, elle sera renvoyée directement.

Elle ne sera pas sérialisée avec un modèle.

Assurez-vous qu'il contient les données souhaitées et que les valeurs soient dans un format JSON valides (si vous utilisez une `JSONResponse`).

Mas, seguindo os passos acima, ele será capaz de fazer algumas otimizações de performance.

Versões modernas de Python têm suporte para **"código assíncrono"** usando algo chamado **"corrotinas"**, com sintaxe **`async` e `await`**.

Vamos ver aquela frase por partes nas seções abaixo:

* **Código assíncrono**

PYTHON_VERSIONS=("python3.9" "python3.10" "python3.11" "python3.12")
for v in "${PYTHON_VERSIONS[@]}"; do
  ln -s "/usr/local/include/${v}" "/${TARGET}/usr/include/x86_64-linux-gnu/${v}"
done

# Patch glibc to be compatable with modern clang
case "${VERSION}" in
devtoolset-9)
  cd /
  patch -p0 < /glibc2.17-inline.patch
;;

Auf die gleiche Weise wie bei Pydantic-Modellen deklarieren Sie Klassenattribute mit Typannotationen und möglicherweise Defaultwerten.

Sie können dieselben Validierungs-Funktionen und -Tools verwenden, die Sie für Pydantic-Modelle verwenden, z. B. verschiedene Datentypen und zusätzliche Validierungen mit `Field()`.

## WebSockets client { #websockets-client }

### In production { #in-production }

In your production system, you probably have a frontend created with a modern framework like React, Vue.js or Angular.

And to communicate using WebSockets with your backend you would probably use your frontend's utilities.
