13Service objects are an important tool in your toolbox, and Dry.rb's Transaction library is one of the most powerful, and one of the most magic. It's a "business transaction" DSL, and has error handling as a primary concern. We'll start by exploring Monads in Ruby (they're not scary!). Then we'll see how that simple concept unlocks another level of service objects that are far more robust and testable, and how to wire them all together with Dry::Transaction. Finally we'll touch on extending transactions with custom steps, and how to integrate them into an existing application.
