It's finally here: the Code and Stuff walkthrough of Ash TypeScript!

Learn how to build an Ash project from scratch, use LiveView to begin, and eject to React without much fuss!

It also fits into @tanstack.com really nicely.

It's a quick one, showing a pattern I use all the time.

I made an Ash extension!

Elixir is capable of hitting services hard; great for throughput but harsh when those services are trying to recover from an outage.

The circuit breaker pattern addresses this issue and is now available in Ash!

My next video is live! This time, I explore the ash_state_machine extension.

Along the way, you'll learn about policies, pubsub, and Oban integration in the demo app!

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!

LLMs don't do a great job of cleaning up after themselves.

The result: developers include way too much of this AI slop in their commits.

Did nobody teach them about git add --patch?

Coming soon: learn how to model payment states with ash_state_machine!

The demo also includes background job processing to simulate payments, auth policies, and real time updates. All made easy with Ash!

Which part are you interested in learning?

Calling multiple services doesn't have to be a nightmare.

My latest video explores Reactor for workflow orchestration. Concurrent execution, automatic rollbacks on failure, and of course: it works with Ash AI.

As promised, a new Phoenix App from Scratch video:

Embedded schemas and an intro to Ecto Multi, all in the context of the demo budget tracker app!

There's even some animations to describe Multi, if you're into that sort of thing.

Oban is probably the greatest library I have ever used, especially with Oban.Pro on top. The value you get for free - or for a very reasonable amount - is mind-blowing.

Embedded Ecto schemas in forms and a brief intro to Multi?

Coming soon in the Budgie series on Code and Stuff!

Did you know @ash-hq.org can import existing database tables as resources automatically?

It can even generate relationships and constraints!
