To add Bootstrap js

Precompile the bootstrap.min.js that comes with the gem, by adding to config/initializers/assets.rb:

• Rails.application.config.assets.precompile += %w( bootstrap.min.js popper.js )

Pin the compiled asset in config/importmap.rb:

• pin "popper", to: 'popper.js', preload: true
• pin "bootstrap", to: 'bootstrap.min.js', preload: true

Include bootstrap in your app/javascript/application.js:

• import "popper"
• import "bootstrap"
• Optionally you might need to run bin/rails assets:precompile to generate the js

Test that Bootstrap js is working
