The Ruby Module Builder Pattern
summary
Shows how to turn Module into a configurable template: subclass Module and use an initializer that defines methods so each included instance carries its own configuration and closures for encapsulation. Replaces brittle bootstrap/anonymous-module patterns used in device/rails with fewer lines and predictable super chains. Applied to the Mobility translation gem to support multiple storage back ends from one interface, echoed by similar refactors in Alchemist and dry-equalizer, and the blog post drew ~30–40k views.
