Go Pro with POROs
summary
Provides concrete, actionable patterns: Service objects that expose a single run/call method and return errors, API wrappers that hide HTTParty‑style requests (examples include a MyRun fetcher and a Twitter poster used end‑to‑end), and a Heroku Connect + Salesforce ActiveRecord wrapper. Shows virtual domain models that capture API results and solved a tricky finance projection dependency, form objects using ActiveModel, Draper/ViewComponent presenters, FastJsonAPI serializers, and a Decanter transformer for strong params and coercion.
