Is it possible to run a script as soon as the server is listening?

Hello, I'm trying to implement the [new Remix development server](https://github.com/remix-run/remix/releases/tag/remix%401.16.0), and I need to call the broadcastDevReady function as soon as the server is being executed. Is it possible to do this using serverless-offline plugin? Thank you in advance for your help!

Start by reviewing the serverless-offline server startup lifecycle and how it exposes hooks or callbacks after the server begins listening. Check whether broadcastDevReady can be invoked at that point; done would require a supported way to run the script immediately after startup, with the behavior documented or covered by an appropriate test.
