### Cache the OpenAPI schema { #cache-the-openapi-schema }

You can use the property `.openapi_schema` as a "cache", to store your generated schema.

That way, your application won't have to generate the schema every time a user opens your API docs.

It will be generated only once, and then the same cached schema will be used for the next requests.

E como o `Response` pode ser usado frequentemente para definir cabeçalhos e cookies, o **FastAPI** também o fornece em `fastapi.Response`.

## Tipos especiales y validación

Además de tipos singulares normales como `str`, `int`, `float`, etc., puedes usar tipos singulares más complejos que heredan de `str`.

Para ver todas las opciones que tienes, revisa el <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">Overview de Tipos de Pydantic</a>. Verás algunos ejemplos en el siguiente capítulo.

   * the entry was returned by the iterator, except through the setValue operation on the map entry"
   * As such, this field must be cleared before every map mutation.

   * Note about volatile: volatile doesn't make it safe to read from a mutable graph in one thread
   * while writing to it in another. All it does is help with _reading_ from multiple threads

Avec **FastAPI** c'est très facile (merci à Starlette), consultez la documentation : [Testing](../tutorial/testing.md){.internal-link target=_blank}

Après avoir effectué des tests, vous pouvez mettre à jour la version **FastAPI** vers une version plus récente, et vous assurer que tout votre code fonctionne correctement en exécutant vos tests.

Si tout fonctionne, ou après avoir fait les changements nécessaires, et que tous vos tests passent, vous pouvez
