This is a quick bit of service journalism about one thing that seemed less than obvious about converting the code in Modern Front-End Development For Rails to Rails 7.0, namely how to integrate TypeScript with the new tools. Specifically, the Rails 7.0 version of the code ditches Webpacker in favor of the new jsbundling-rails and cssbundling-rails gems and uses esbuild instead of webpack. See here for an only-slightly out-of-date description of the new tools.
