Add gem to Gemfile
gem 'gi-dom-rails', github: 'ibaciulis/gi-dom-rails'
After you install, you need to run the generator:
rails generate dom:install
Require gi-dom-rails and generated JS files:
//= require gi-dom-rails
//= require core/core
//= require core/widgets
//= require core/pages
//= require pages
Add controller and action values to body attribute:
<body data-controller="#{controller.controller_path}" data-action="#{controller.action_name}">
Or
= content_tag :body, data: { controller: controller.controller_path, action: controller.action_name }
For example, you want to generate page specific JS for Account::Orders#index:
rails generate dom:page account/orders/index
It will generate these JS files:
app/assets/javascripts/pages/account.coffee
app/assets/javascripts/pages/account/orders.coffee
app/assets/javascripts/pages/account/orders/index.coffee
Define custom namespace and path
rails generate dom:page search_logs/index --namespace Admin --path engines/admin/app/assets/javascripts/admin
Generated files:
engines/admin/app/assets/javascripts/admin/pages/search_logs.coffee
engines/admin/app/assets/javascripts/admin/pages/search_logs/index.coffee
