RailsAssetslessContainer

If you're delivering assets via a CDN, you don't need to include assets in your container.

This gem provides a way to do that.

Add this line to your application's Gemfile:

gem 'rails_assetsless_container'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install rails_assetsless_container

It is disabled by default, so specify it explicitly with config/environments/production.rb.

Rails.application.configure do
  # some settings
end

RailsAssetslessContainer.configure do |config|
  config.enabled = true
end

Save the manifest file as manifest-<suffix>.json after assets:precompile.

Download manifest-<suffix>.json via CDN and save it as manifest.json before starting the server.

see: lib/rails_assetsless_container/strategy/asset_server.rb

A strategy for checking each method call for debugging.

RailsAssetslessContainer.configure do |config|
  config.enabled = true
  logger = Logger.new(STDOUT)
  config.strategy = RailsAssetslessContainer::Strategy::Log.new(logger)
end

see: lib/rails_assetsless_container/strategy/log.rb

You can also use custom strategy.

class CustomStrategy < RailsAssetslessContainer::Strategy::Base
  def after_sprockets(path)
    # To save the manifest from `path`.
  end

  def after_webpacker(path)
    # To save the manifest from `path`.
  end

  def write_sprockets_manifest(path)
    # To write the manifest to `path`.
  end

  def write_webpacker_manifest(path)
    # To write the manifest to `path`.
  end
end

RailsAssetslessContainer.configure do |config|
  config.enabled = true
  config.strategy = CustomStrategy.new
end

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