Rake::Sprockets

Very easy defaults for using sprockets through rake.

Installation

Add this line to your application's Gemfile:

gem 'rake-asset-pipeline'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rake-asset-pipeline

The default expected folder structure is:

assets/
  js/app.js
  css/app.css
public/

Build the assets with:

$ rake build

This will produce the following new files:

public/assets/js/app.js
public/assets/css/app.css

These are the settings that can be overriden in your Rakefile:

The default is Dir.pwd.

Rake::Sprockets.root = Pathname.new __dir__

The default is $stdout.

Rake::Sprockets.logger = Logger.new("log/output.log")

#env is set to RAKE_ENV or defaults to development.

#env is fancy and can answer queries:

Rake::Sprockets.env.production?

Override from the shell:

$ RAKE_ENV=production rake build

The default is to only compile app.js and app.css. You can add more files:

Rake::Sprockets.precompile += ["other.css", "cray.js"]

The default asset directories are assets/js and assets/css. You can change or add more:

Rake::Sprockets.asset_paths = ["stylesheets", "javascripts"] # "assets/" is prepended

In production compression is used if it's setup. You need to supply the js and css compressors (there are no defaults):

Rake::Sprockets.css_compressor = :sass
Rake::Sprockets.js_compressor  = :uglify
