packwerk

Shopify would benefit a ton from "some" namespaces. In a way, packwerk[0] was an attempt at bringing some namespaces benefits. But I don't personally think Shopify would benefit from this specific implementation of namespaces (a couple colleagues do). I'm personally not even sure Namespace is a proper term to describe that feature. It's more some sort of lightweight sandboxing to me. Also: > They have so many expert Ruby devs If anything, the average Ruby expertise at Shopify is likely noticeably lower than in most Ruby/Rails shop. [0] https://github.com/Shopify/packwerk

I use it at Justworks and love it! Packwerk [1] is another personal favorite [1] https://github.com/Shopify/packwerk

Yep, that article is about very similar concepts but grounded in Spring as the framework. I like what they do around package imports and it looks a lot like what we do at incident.io, with some rules about which packages can import what. For people in the Ruby world who want a similar solution, Shopify provide an open-source framework called packwerk that is designed just for this: https://github.com/Shopify/packwerk
