🗓️ Talk at Euruko 2025 – Viana do Castelo, Portugal
📅 September 19, 2025
This talk marks the next chapter in a journey Marco Roth has been sharing throughout 2025.
At RubyKaigi, he introduced *Herb* — a new HTML-aware ERB parser and tooling ecosystem. At RailsConf, he released developer tools built on Herb, including a formatter, linter, and language server, all aimed at modernizing the Rails view layer.
Now at Euruko, Marco presents **ReActionView**: a new ERB engine built on Herb, fully compatible with `.html.erb` but offering:
✅ HTML validation
🛠️ Better error feedback
⚡ Reactive updates
🔧 Built-in tooling
