Understanding the Ash Framework and Its Domain-Centric Approach

The article explores the Ash Framework, which challenges the conventional approach of modeling applications by starting with database persistence. Instead, Ash emphasizes modeling the domain itself. The framework operates on three main principles: prioritizing data over code, favoring logic derivation over manual coding, and describing what should happen rather than detailing how. The author discusses the extensive use of code generation within Ash, noting types of generators like scaffolds, repeatable generators, ongoing regeneration, and compile-time macros, which all contribute to a seamless development experience. By contrasting Ash with frameworks like Rails, the author illustrates how Ash's domain-centric approach offers a more intuitive way to manage application logic, creating a dynamic link between the domain model and the generated code.
