This is genuinely incredible! Reactivity like React for humans, and simple, clean html for agents and low-bandwidth users.
Marco Roth@marcoroth.dev · 2w agoToday 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.
The recording of my #RailsWorld 2026 talk, where I introduced the reactivity in ReActionView v0.6, is now live on the Rails YouTube channel: www.youtube.com/watch?v=REtf...

yrby is getting to a really strong place. I’m running it in production, and I’ve expanded quite a bit beyond my meager early ambitions I want it to be the first-class answer for realtime collaboration in Ruby/rails, without having to reach for node or any other tool

At this point, I feel like I have enough material for @drbragg.dev to make a special edition of his game show: “Who Wants to be an ERB Engineer?”
Been prototyping a new "Extract to Partial" Code Action for the Herb Language Server 🌿 Since it knows which variables your selected text uses, it can create the partial, define strict locals, rewrite all references, and replace the selected code with the proper render call ✨

I don't mind reading code written by agents, but I hate reading their PR descriptions. If I can't make myself read a PR description from Claude, I won't expect others to. Now when delivering PRs, I may not have written the code by hand, but I'll certainly write the description.
We love ruby events and we want to support their growth. These guides are a fantastic resource for new organizers and those looking for new ideas. Thank you to all the organizers who contributed, and @hansschnedlitz.com for putting these guides together. Welcome to the team, Hans!
Hans Schnedlitz@hansschnedlitz.com · 3mo agoRubyEvents Guides is now live. Over the last few months, I talked to Rubyists who want to help the community keep going. Some want to restart a local meetup. Some are organizing their first small conference. Some already run events and want to make the next one better.
