[Marco Roth](https://marcoroth.dev), independent consultant and the creator of [Herb](https://herb-tools.dev) and <a href="https://reactionview.dev"”>ReActionView</a>, joins Robby to talk about teaching Rails to understand its own templates.

Marco explains how Herb parses HTML and ERB together, why that lets it catch broken views long before they reach production, and how it is set to become part of Rails 8.2. They also get into how ReActionView makes Rails views reactive without rewriting them, the story behind [RubyEvents.org](https://rubyevents.org), and why tooling like Herb matters even more when AI agents are writing your templates.
