# Adds a route for JavaScript files.
#
# == Usage
#
# require 'sinatra/support/jssupport'
#
# class Main < Sinatra::Base
# register Sinatra::JsSupport
# serve_js '/js', from: './app/js'
# end
#
# You'll be able to access files via +/js+:
#
# # This will serve /app/js/jquery.js. (or .coffee)
# $ curl "http://localhost:4567/js/jquery.js"
#
# == CoffeeScript support
#
# This plugin supports CoffeeScript. To use it, simply
# add a CoffeeScript file in the JS file path.
#
# # Will first try app/js/application.coffee,
# # then move onto app/js/application.js if it's not found.
#
# $ curl "http://localhost:4567/js/application.js"
#
# To use CoffeeScript, install the +coffee_script+ gem.
# If you're using Bundler, that is:
#
# # Gemfile
# gem "coffee-script", require: "coffee_script"
#
module Sinatra::JsSupport
