Ash Framework for Phoenix Developers

The hands-on, no-fluff guide that finally shows Phoenix developers how to stop writing the same boilerplate over and over and start shipping robust, secure, production-grade Elixir applications in a fraction of the time.

Written by a battle-tested Phoenix engineer who has built and shipped real-world systems in healthcare, manufacturing, and HR, this book takes you from “I’ve heard Ash is powerful” to “I just built a complete multi-tenant help-center in weeks instead of months.”

You’ll go far beyond the official docs. Through a single, real production application (a fully-featured multi-tenant knowledge base with categories, articles, nested comments, tagging, feedback, search, and admin tools) and by writing, testing, configuring, and publishing your own Ash extension to Hex.pm as a reusable Elixir package, you will master every layer of Ash:

• Declare your domain once with Resources and Domains—Ash generates migrations, relationships, constraints, and keeps everything in sync forever
• Master actions, changesets, calculations, aggregates, policies, and code interfaces the way Ash was designed to be used
• Build bulletproof, database-driven authorization that scales from simple roles to dynamic permissions
• Wire Ash into LiveView, PubSub, Oban, and Phoenix channels with zero friction
• Dive deep into Spark and write real Ash extensions: transformers, configurasble sections, custom changes, atomic hooks, and full test suites—the exact techniques behind ash_authentication, ash_archival, and ash_json_api
• Publish your own hex package (you’ll ship AshParental, a production-ready single-table parent/child extension, to hex.pm by the end of the book)

This isn’t theory. Every line of code has run in production. Every pattern has survived real users, real bugs, and real deadlines.

If you already love Phoenix and are ready to 4x your throughput while writing cleaner, safer, more maintainable systems, this is the Ash book you need.
