Use Browser Sync with Rails. This gem provides installers to get you going with live reloading and browser syncing — works beautifully with cssbundling-rails and jsbundling-rails.

Whenever Browser Sync detects changes to any assets or views, it will trigger a browser reload. You can configure Browser Sync via the generated bs-config.js — it's preconfigured to inject into head rather than body, due to turbo's body replacement.

You must already have node and yarn installed on your system, then:

1. Add browsersyncing-rails to your Gemfile with gem 'browsersyncing-rails'
2. Run ./bin/bundle install
3. Run ./bin/rails browsersyncing:install

Just run ./bin/dev and visit localhost:3001 to access your Rails instance via the Browser Sync proxy, and localhost:3002 to access the Browser Sync UI; Rails runs on localhost:3000 as usual.
