rake-uglifier

A simple rake task for minifying assets and include optional source maps.

Installation

$ gem install rake-uglifier

Setup

Here is how you set it up:

require 'rake/uglifier_task'

# :minify is the name of the task
Rake::UglifierTask.new(:minify) do |t|
  t.assets_path      = File.join(File.dirname(__FILE__), 'public', 'assets')
  t.logger           = Logger.new($stdout)
  t.uglifier_options = {
    mangle: {
      except: %w($ jQuery someOtherGlobalVariable)
    }
  }
end

These are the different options:

# A Hash containing the options to give to uglifier
:uglifier_options

# The name of the task, defaults to :minify
:name

# The logger to use
:logger

# A list of regexps that should match any assets to compile
# Defaults to all file ending in .js
:assets

# A list of regexps to ignore
# Default to all minified files
:assets

# A booleaning indicating whether or not to create source maps
:create_source_map

# The path to the root directory where the assets are located.
:assets_path
