rake tasks for bower on rails

bower-rails

rake tasks for bower on rails. Dependency file is bower.json in Rails root dir.

Requirements

• node (on github)
• bower (>= 0.10.0) installed with npm

Install

in Gemfile

	gem "bower-rails", "~> 0.4.0"

Initialize

To add an empty bower.json file to the project root.

	rails g bower_rails:initialize

##JSON configuration

The bower.json file is two seperate bower component.js files. Defining a package in lib and vendor will install those packages to the corresponding directories.

example bower.json file

{
   "lib": {
    "name": "bower-rails generated lib assets",
    "dependencies": {
      "threex"      : "[e-mail]:rharriso/threex.git",
      "gsvpano.js"  : "https://github.com/rharriso/GSVPano.js/blob/master/src/GSVPano.js"
    }
  },
  "vendor": {
    "name": "bower-rails generated vendor assets",
    "dependencies": {
      "three.js"    : "https://raw.github.com/mrdoob/three.js/master/build/three.js"
    }
  }
}

Available commands

  rake bower:install #install js components
  rake bower:update  #update js components

##Ruby DSL configuration

The Ruby DSL configuration is a Jsfile with DSL syntax similar to Bundler.

Example Jsfile

By default assets are put to ./vendor/assets/bower_components directory:

# Puts to ./vendor/assets/bower_components
js "backbone"
js "moment"

But the default value can be overridden by assets_path method:

assets_path "assets/my_javascripts"

# Puts to ./vendor/assets/my_javascripts/bower_components
js "backbone"
js "moment"

And finally, the assets_path method can be overridden by an option in a group call:

assets_path "assets/javascript"

# Puts files under ./vendor/assets/js/bower_components
group :vendor, :assets_path => "assets/js"  do
  js "jquery"            # Assummes it's latests
  js "backbone", "1.2"
end

# Puts files under ./lib/assets/javascript/bower_components
group :lib do
  js "jquery"
  js "backbone", "1.2"
end

NOTE: All the assets should be stored in /assets subdirectory so putting it under ./vendor/js directory is unavailable

Available commands with a Jsfile

  rake bower:dsl:install #install js components
  rake bower:dsl:update  #update js components
