Integrating Ash Framework into Existing Codebases

In this article, the author discusses how to incorporate the Ash Framework into an existing Elixir project, particularly one that does not utilize a database or Ecto. The project involves managing superheroes within a distributed system, where Ash is integrated without requiring significant rewrites of existing code. Koski elaborates on converting existing structs into Ash resources, implementing CRUD operations with Ash, and structuring the code to utilize Ash effectively. The author highlights the ease of integration when the foundational logic is sound and the potential benefits, such as validation and composable side effects, that Ash provides even to established systems. The conclusion asserts that Ash Framework can enhance organization and introduce helpful features to legacy codebases without fixing all technical debt, emphasizing the value of modeling one's domain.
