Today is a big day for Herb! It's built into Rails 8.2 by default for all HTML+ERB views.
My talk at #RailsWorld in Austin today answered three questions: What is Herb? What ships in Rails 8.2? And what does this enable?
Herb v0.11 and ReActionView v0.6 released alongside it.

Communities and friendships are more fragile than you think. They are worth more than you think.

The answer to "what does this enable?" is ReActionView v0.6, which introduces LiveView-like, fine-grained reactivity for Rails.
You declare state in your view like strict locals, read it in plain Ruby, and write it from HTML attributes. Updates happen at the slot level, so only the changed values are updated. No JavaScript framework and no new file format needed.

I'm really happy with the direction Herb and ReActionView are taking, but I can't do it all by myself. Please try the tools, report issues, and give feedback!

The recording of last month's SF Ruby meetup at @GustoHQ is live! 🚨
Highlights of the night:
- @inazarova declared August 25 as the official Herb day, because earlier that morning @marcoroth_'s tool was merged into @rails
- Edward Kim (@edawerd) from Gusto walked us through the learnings of building "Gusto CoFounder"
- Madison Sites from @OrderCo_ gave an amazing presentation titled: "Legacy Rails and the AI that couldn't"
- We had Harsh Parekh (@parekhharsh_) explain his test infrastructure for async workflows using Rails/Sidekiq
As usual, we ended the session with 30-60-second on-stage intros. Similar to what we'll do in our conversation groups at @sfrubyconf.
Want to speak at the next meetup? Fill out the form linked in the video description.

If you care about programmer delight and Ruby, join the @sfrubyconf - the movement to bring Ruby into the future, into new companies and products and support new growth stories!
When we say we want to build the future of Ruby, we mean it.
And that's what we're planning to inspire you to do at the conference.
Our thinking is that if you talk to each other and discuss struggles, you'll find repeated problems, come up with ideas to solve them, and build the future that we want/need for Ruby.
This is how we learned about Inertia Rails.
@inazarova interviewed multiple Rails founders for her keynote at @railsconf 2024. They all complained about wanting to use React but not having an easy way to do it on Rails apps.
This insight led us to find the work that @brandonshar and @BrianKnoles were doing with Inertia and get @skryukov_dev to lead this work at Evil Martians.
Who knows who'll inspire you to build your next big project. Come meet them at the conference: luma.com/sfrubyconf2026?utm_…

Spotted: A handful of gems dropped by Sutro Tower.
Go catch them before @travis_code and @marcoroth_ take them all!
