Preparation

New Rails Application

Create your new application skipping all javascript assets and sprockets (where "my_app" refers to your app name).

rails new my_app --skip-javascript --skip-turbolinks --skip-sprockets

Existing Rails Applications

Remove sprockets from your application loaded modules inside the config/application.rb file.

If you used the default Rails generator, then replace the line require 'rails/all' with:

require 'rails'
# Pick the frameworks you want: 
require 'active_model/railtie'
require 'active_job/railtie'
require 'active_record/railtie'
require 'action_controller/railtie'
require 'action_mailer/railtie'
require 'action_view/railtie'
# require 'sprockets/railtie' 
require 'rails/test_unit/railtie'

If you used a custom Rails app generation, just remove the line:

require 'sprockets/railtie'

Installation

Add this line to your application's Gemfile:

gem 'hauler'

And then execute:

bundle
bin/rails generate hauler:install

Set your application config.action_controller.asset_host using an environment variable.

export ASSET_HOST="//localhost:8080"

# config/application.rb 
config.action_controller.asset_host = ENV.fetch('ASSET_HOST')

Update

bin/rails generate hauler:install

Usage

Run your rails server normally:

bin/rails server

In a different terminal window run Webpack dev server:

npm start

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
