At Rails World 2025, I introduced ReActionView, an initiative to explore what's possible in the Rails view layer for 2025 and beyond. As part of this, I announced Herb::Engine, an ActionView-compatible ERB engine built on top of the HTML-aware Herb Parser. #RailsWorld2025

It brings better error messages, modern tooling, and new view features to Rails while staying backwards-compatible. I'm going to publish and summarize the talk in written form on my blog in the next few days, stay tuned!

In the meantime, please give Herb and ReActionView a star on GitHub and report any issue you might encounter! Thank you! github.com/marcoroth/herb

I'm super excited about the future of the Rails view layer, and would love to see how far we can take it!
