Rails 6: How to disable Webpack and use Sprockets instead
I found this link helpful, I will crosspost here:
Use option --skip-webpack-install when generating a new app
Change Gemfile, remove webpacker, add:
gem 'sass-rails', '>= 5'gem 'sprockets', '~> 4'gem 'sprockets-rails', :require => 'sprockets/railtie'Then
bundle update sass-rails sprockets # if you are updating bundle install # or simply installIf you are using sprockets 4, change app/assets/config/manifest.js to:
//= link_tree ../images//= link application.js//= link application.cssIf you are using sprockets 3, add to config/initializers/assets.rb:
# Rails.application.config.assets.precompile += %w( application.js )Restore app/assets/javascripts/application.js:
//= require rails-ujs//= require turbolinks//= require_tree .Change javascript_pack_tag to javascript_include_tag in app/views/layout/application.html.erb
If you want to skip adding webpacker gem when generating new rails application, use --skip-javascript (since Webpacker the default JavaScript compiler for Rails 6).
