Taking a workshop at Rocky Mountain Ruby on "Component Based Rails Applications" with Stephan Hagemann (the author of that book) was my introduction to all of this stuff! I found Hanami (then called Lotus) shortly after and I never looked back.
I tried out Rails Engines on a couple projects, with such high hopes and ran into issue after issue. Sure it's theoretically possible to build whatever you want with Rails, but in practice it's infeasible. Some people have experimented with arbitrarily nesting Hanami slices too and had success. It's not something we're focusing efforts on because it's rather niche and get inherently complicated but it's possible.
Modularity is such an important part of large software projects and Rails doesn't give you any tools for it (and Ruby doesn't help either). Packwerk was an attempt to constraint Rails, with limited success: https://shopify.engineering/a-packwerk-retrospective.
Small world! We were one of the clients at labs he tested that concept with while developing the book. Chatted with him about his newer book using packwerk a couple years back. Looks like we’re all on the front range!
Agree on the engines, you’re just fighting the framework the whole way.
Coincidentally working on modularity approaches for a different type of monolith https://viaduct.airbnb.tech/ (time is a flat circle etc. etc.)
