webpack_assets

adds a webpack build step into your rails assets:precompile rake task

Add this line to your application's Gemfile:

gem 'webpack_assets'

And then execute:

$ bundle

Or install it yourself as:

$ gem install webpack_assets

webpack_assets assumes you have a webpack build with a webpack.config.js in your rails project root. By default it also assumes your webpack build is building a javascript bundle into app/assets/javascripts/bundle.js. If your webpack config builds a file into a different location, or with a different name, update your config/application.rb file:

# config/application.rb
config.webpack_build_path = 'app/assets/javascripts/your-js-file.js'

For multiple files an array may be used:

# config/application.rb
config.webpack_build_path = [
  'app/assets/javascripts/your-js-file1.js',
  'app/assets/javascripts/your-js-file2.js',
  'app/assets/javascripts/your-js-file3.js'
]

Including the gem will automatically inject the webpack build into the precompilation of assets. To run your webpack build manually execute:

bin/rake assets:webpack

To watch for changes from your webpack build files and compile per change, execute:

bin/rake assets:webpack:watch

webpack_assets assumes you have a webpack build. If you don't, never fear:

cd <your-rails-root>
bin/rails g webpack_assets:init #will build webpack.config.js, and package.json
npm install

Edit the entry point of the newly created webpack.config.js and you should be on your way.
