上面的应用程序是一个最小和简单的示例，用于演示如何处理和向多个 WebSocket 连接广播消息。

但请记住，由于所有内容都在内存中以单个列表的形式处理，因此它只能在进程运行时工作，并且只能使用单个进程。

如果您需要与 FastAPI 集成更简单但更强大的功能，支持 Redis、PostgreSQL 或其他功能，请查看 [encode/broadcaster](https://github.com/encode/broadcaster)。

Para aprender más sobre las opciones, revisa la documentación de Starlette para:

 * includes both natural exceptions such as unreachable servers, as well as synthetic exceptions
 * when responses are of an unexpected type or cannot be decoded.
 *
 * Other exception types cancel the current call:
 *
 *  * For synchronous calls made with [Call.execute], the exception is propagated to the caller.
