Code Master Blog: Exercises for the wroclove.rb 2026 Ruby conference workshop "Building Rails SPAs in Frontend Ruby with Glimmer DSL for Web"

Andy Maleh published a GitHub repo with 11 workshop exercises for the wroclove.rb 2026 conference, focused on building Rails SPAs using Glimmer DSL for Web — a Ruby-in-the-browser frontend framework that uses Opal (Ruby-to-JavaScript transpiler). The exercises use a pre-configured e-commerce Rails app so learners can skip setup and dive straight into frontend Ruby development. The post also notes that Glimmer DSL for Web now has official Rails 8 setup instructions, and provides a pragmatic decision framework for when to use Turbo, Hotwire, Stimulus, or Glimmer DSL for Web based on the complexity of frontend interactions needed.
