Pero en algunos casos necesitas devolver un código de estado diferente al predeterminado.

## Caso de uso

Por ejemplo, imagina que quieres devolver un código de estado HTTP de "OK" `200` por defecto.

Pero si los datos no existieran, quieres crearlos y devolver un código de estado HTTP de "CREATED" `201`.

Pero todavía quieres poder filtrar y convertir los datos que devuelves con un `response_model`.

     * @param userToolchainsFile The path to the toolchains file, may be <code>null</code> to disable parsing.
     * @return The toolchains model or <code>null</code> if no toolchain file was configured or the configured file does
     *         not exist.
     * @throws MisconfiguredToolchainException If the toolchain file exists but cannot be parsed.

Pero para este ejemplo, usaremos un documento HTML muy simple con algo de JavaScript, todo dentro de un string largo.

Esto, por supuesto, no es lo ideal y no lo usarías para producción.

En producción tendrías una de las opciones anteriores.

Pero es la forma más sencilla de enfocarse en el lado del servidor de WebSockets y tener un ejemplo funcional:

# GraphQL

Como o **FastAPI** é baseado no padrão **ASGI**, é muito fácil integrar qualquer biblioteca **GraphQL** também compatível com ASGI.

Você pode combinar *operações de rota* normais do FastAPI com GraphQL na mesma aplicação.

/// tip | Dica

**GraphQL** resolve alguns casos de uso muito específicos.

Ele tem **vantagens** e **desvantagens** quando comparado a **web APIs** comuns.
