I cannot stress enough how amazing Ash’s timing was with AI coding agents. Its design is absolutely perfect for building apps with tools like Claude that don’t ever get tired and just code things the right way. The DSL for attributes, relationships, actions, policies, aggregates, etc make the agent’s job almost feel effortless. Policy enforcement specifically has been bonkers easy and so utterly powerful. Drink the kool aid!

Docs: hexdocs.pm/ash_json_api...

AshJsonApi 1.6-rc.1 is out that allows transforming fields, with convenient builtins for camelizing/dasherizing fields. This applies automatically to reading, writing, filtering, sorting, field selection: everything 😎 #AshFramework #ElixirLang

Docs: hexdocs.pm/ash_admin/1....

AshAdmin 1.0rc is out, with a complete UI overhaul, a rework of our markdown/json editor to code mirror, and features for more convenient relationship management and multitenancy drop-down/typeahead 🎉 #AshFramework #ElixirLang

Constructing skills with your usage_rules

usage_rules now supports copying skills from your packages in addition constructing skills from the usage rules files 😎 Package authors can now provide entire skills for your project, and when you update your dep you can get the new version of the skill! #ElixirLang

See the docs for more: hexdocs.pm/ash_typescri...

📢The latest AshTypescript release brings you t typed controllers🎉 Using Typescript with Phoenix has never been easier, with or without #AshFramework. Thanks to Torkild for his awesome package! I might be working on a PR for something pretty cool there myself 😎 #ElixirLang

Thanks for the feedback!. I'd suggest much of the topics you'd like to see just don't fit in what the first book on the topic. Has to be widely accessible. Maybe an advanced book later. For comparing to alternatives, I think also there are better venues. At least its not one star 😂

For more information, check out the docs: hexdocs.pm/ash_oban/0.8...

AshOban v0.8.0-rc.0 is out, with support for Oban Pro's chunk workers! This allows you to leverage #AshFramework's ability to run any action as a bulk action(with progressive enhancement) to process many records at a time without having to modify your trigger logic at all 😎

Honestly I get why some people aren't into LLMs & GenAI. It's a real life version of Rita Skeeter's Quick-Quotes Quill.

If I want to get started with a home lab, self-hosting some apps, setting up network controls, running smart home systems etc, where should I start?

I am stunned by how big the effect of usage_rules is. Forgot to add it recently to a new project, and only noticed because the agent performed way below what I was used to. Thank you for this initiative!

arxiv.org/abs/2602.12670 This is why hexdocs.pm/usage_rules exists. Package authors need to be providing the context that will guide your agent to successfully use their package. As their library changes, they can update their agent guidance. #ElixirLang

Software Conjuring Software engineering is becoming a mystic art

Wrote a little thing: open.substack.com/pub/zachdani...

🤔 I'm not sure about that. I mean you can, but one overwrites the other. We conditionally define that module different ways depending on if `Plug` is available.

Yes, I'd definitely accept that. Perhaps `mix usage_rules.info` listing all available and `mix usage_rules.info package` listing those for that package?

This person made a production management tool for his spouse's bakery in #ElixirLang + Ash + LiveView. It's super valuable to have an codebase like this be open source for people trying to get into that tech stack. 💜

Tidewave The coding agent for full-stack web app development

Sharing just cuz I used Claude Opus to make something similar last week for a client. I knew the data model, and I am well versed in Elixir and Ash. Within 8 hours I had a shippable full featured and tested product. Claude was amazing for Ash Policies. Tidewave.ai also made the speed possible.

You can now set attributes to the results of expressions in create actions. This can be useful for a whole slew of reasons, one of which is being able to use aggregates, fragments, etc. Especially powerful when paired with upserts.

If you haven't, I'd take a peek at Spark, might make your DSL life easier and have less hair pulling out 😂 hexdocs.pm/spark

Very nifty little #AshFramework extension just released 🤯 #ElixirLang

Ah gotcha. It looks very similar to the type of DSL you can write with Spark, thought it might be an implementation from that. Anonymous functions in DSLs isn't easy, well done 😅

Are you using something to build that DSL or did you hand-write it?

Reactor hitting 1.0 and AshAuthentication hitting 5.0 (rc) within just a few days of each other is epic. TOTP now comes out of the box with AshAuthentication 👀 #AshFramework #ElixirLang
