Hey, just to let you know that this on my radar, but I was thinking, instead of having a cli command (which may be really helpful with CI/CD and scripts, but may require extra work to run headless) What about having a very simple API that returns the JSON, (and maybe some endpoint to force a sync)
The caveat is that in it will require that the user have the app open. Also, this would mean that this API could be potentially hit from any computer (with network access) Also, this would mean that, it could be possible in theory, and some imagination… to hook up the game engine to use the API directly for some live preview goodness.
Is not a headless/“offline” solution but its definitely simpler to implement!
