There is an API at localhost:31000 and there is a hidden one-shot mode to rerun a flow if you happen to work the command line just right, so it is technically feasible to integrate with CI/CD, though all that needs proper docs before we would expect anyone to reasonably do that. It is on our roadmap though, and the lift is not high.

Regarding exporting to Javascript, seems you found the button for it. Though we like to call it a "draft of a script", as it is generated by an eager-to-please LLM, so having a real engineer give it a look over is useful. It should be enough to get you off the ground though.
