TIL: Html + ERB = HERB ❤️

Today I was looking to improve the tooling around ERB templates in our project, get a linter at least. I started with erb_lint gem, but soon discovered the HERB project. The docs are a bit cryptic, but it's basically a gem that gives you a powerful linter a-la rubocop. gem "herb" gives you a powerful, multi-function CLI tool: bundle exec herb analyze parses templates for HTML wellformedness bundle exec herb lint works much like rubocop, check out the many rules available (and you can even write custom ones in JS!) https://herb-tools.dev/linter/rules/
