Wow this is cool. I actually spent a lot of time developing a solution for this for the last company I worked for. I copied the Angular repos way of doing it. https://github.com/angular/angular/blob/master/aio/aio-build...
It's really well documented and made the whole process a lot less work. It works great for angular apps.
There doesn't seem to be a ton of services in this space and for larger teams working on the same product I see this solving an actual problem.
Congrats on launching, excited to see where this goes.
