The Secret to Side-by-Side Gem Development in Rails

When developing Ruby gems alongside a Rails app, you don't need to push to GitHub to test changes. Using Bundler's `path:` option in the Gemfile points directly to a local gem folder, enabling instant feedback. For contributing to established gems without risking a broken Gemfile commit, `bundle config local.<gemname> /path` overrides the gem source locally without touching the Gemfile. Both techniques eliminate the slow push-test-update loop and make gem extraction from Rails monoliths practical.
