>>>     return ServerAppComponents(
>>>         strategy=strategy,
>>>         server_config=server_config,
>>>     )
>>>
>>> app = ServerApp(server_fn=server_fn)

Use the ServerApp with a custom main function:

>>> app = ServerApp()
>>>
>>> @app.main()
>>> def main(driver: Driver, context: Context) -> None:
>>>    print("ServerApp running")
