Bower でインストールしたコンポーネントを Padrino で参照できるようにしてみた（要 gem 'sprockets'）

config.ru

#!/usr/bin/env rackup
# encoding: utf-8

# This file can be used to start Padrino,
# just execute it from the command line.

require File.expand_path("../config/boot.rb", __FILE__)

# Bower components を /assets/* で参照できるようにする
if File.exists?('.bowerrc')
  bowerrc = JSON.load(File.open('.bowerrc'))
  assets_root = bowerrc['directory']

  assets = Dir[File.join(assets_root, '*')].collect { |path|
    dist = File.join(path, 'dist')
    path = dist if Dir.exists?(dist)
    path
  }

  map '/assets' do
    environment = Sprockets::Environment.new
    assets.each { |path| environment.append_path path }
    run environment
  end
end

run Padrino.application
