I started a fresh rails 7 application using jsbundling-rails (with esbuild) and cssbundling-rails (with bootstrap).
The pipeline works well to build assets. After testing that, I removed sprockets gem and configs from application (basically, I removed all calls with .assets on config files)
So, after remove sprocket, my assets can't be reach from frontend
<%= javascript_include_tag 'application' %>
I'm debugging but it isn't clear what's wrong...
After I've seen some tutorials, I discovered which sprockets can't be removed.
While I'm upgrading I removed a lot of gems, and someone that import sprockets as a dependency.
I fixed adding sprockets directly:
gem "sprockets-rails", :require => "sprockets/railtie"
I also simplified my assets.rb file:
# Be sure to restart your server when you modify this file.
# Version of your assets, change this if you want to expire all your assets.
Rails.application.config.assets.version = "1.0"
# Add additional assets to the asset load path.
# Rails.application.config.assets.paths << Emoji.images_path
Rails.application.config.assets.paths << Rails.root.join("node_modules/bootstrap-icons/font")
Rails.application.config.assets.paths << Rails.root.join("node_modules/@fortawesome/fontawesome-free/webfonts")
Rails.application.config.assets.paths << Rails.root.join("node_modules/summernote/dist/font")
Rails.application.config.assets.paths << Rails.root.join("app/assets/fonts")
# Rails.application.config.assets.precompile << /\.(?:svg|eot|woff|ttf)\z/
# Precompile additional assets.
# application.js, application.css, and all non-JS/CSS in the app/assets
# folder are already added.
# Rails.application.config.assets.precompile += %w( admin.js admin.css )
It's important search for other files which use .assets from code.
My manifest.js file (sprockets looks to that file):
//= link_tree ../images
//= link_tree ../builds
