Hi,
i set up a little tool so sync up fields from JSON for developers, while it will keep reading it from JSON in production environment.
You basically just need to update the field version constant whenever you update a field group, and next time someone pull code from your repo, fields from JSON are imported back in DB for further editing.
check it here : https://gist.github.com/FreshFlesh/54fc4296fda3de4f4f52
any improvement to this workflow would be appreciated 🙂
