With this release, we add a generator script inside of our module. The goal was pretty simple - sometimes you want to update your JSON structure, for example add an ID, or something else. So your current file cannot fit your functionality.
Before we just read that file, made loop, add missing fields and return a new version of the array. But we do it again and again.
It's a stupid way! generator can help us to create a new json files/structures for projects that we working on.
