Ash Chronicle!
Welcome to Ash Chronicle — your quick, informal digest of what’s new and notable in the world of Ash Framework. Got something cool? Drop it in the #showcase channel on Discord!
Shameless Plugs
Check out Ash Premium Support from Alembic.
Sponsor me if you like what I do. To all of my current sponsors: thank you ❤️
Official Ash T-Shirts
Thanks to OSwag, from our dear friend Lars Wikman, and an initial investment from Alembic, you can now acquire an Ash T-Shirt! They are very high quality, and you can also get Nerves and Elixir shirts there 🥳
Complex Workflows in Elixir with Reactor (+ AI Agents)
Christian Alexander, via his youtube channel Code and Stuff, has been exploring various aspects of the Ash ecosystem and his latest video on Reactor is frankly stunning. So well crafted and delivered, can’t wait to see what he does next 😉.
The Next Dimension of Developer Experience
My talk from AlchemyConf about is up! Watch me slightly fumble a very long live demo 🤣
Jax.Ex presentation on building a Discord bot with Ash AI
Barnabas (core team member and AI extraordinaire) gave a presentation at Jax.Ex showing his really awesome in-progress discord bot using Ash AI. Super cool stuff, and you get to see a lot of the nitty gritty code behind the scenes 😎
Migrating my Existing Elixir App to Ash Framework
Check out Matt Savvy’s blog post describing how he migrated his existing app to Ash, what went well and what could have gone better. Really great to see practical steps taken and advice like this.
Background AI Translator in Ash
Check out Ken’s article on building a background AI Translator in Ash! With tons of code examples and instruction for how to achieve similar results, its a great entry to the Ash media archive, and its his first article even!
Ash.TypedStruct
You’ve always been able to define typed structs using `Ash.Type.NewType`, but we’ve introduced a nice compact syntax inspired by other typed_struct packages. This one, however, is built into Ash and uses Ash’s type system, meaning it plays nicely with all the other parts of the Ash ecosystem 🎉
Validations now supported on read actions
Read actions now support validations, as well as using validations in a `where` option on preparations. Prior to this, you would have to write validations as custom preparation functions, which was verbose and prevented reusing existing elements in your system. Now you can have your cake and eat it too!
Usage Rules & documentation tasks
hexdocs.pm/usage_rules now includes powerful docs-search tasks, and instructs agents to use them for research. Please, if you are working with LLMs and Elixir, try it out. It helps even when packages haven't written usage-rules files, thanks to the new docs tools!
