rack-coffee

Simple rack middleware for serving up CoffeeScript files as compiled javascript.

Usage

The options behave similarly to Rack::Static:

require 'rack/coffee'
use Rack::Coffee, {
    :root => '/path/to/directory/above/url',
    :urls => '/javascipts'
}

For rails, presuming you've required 'rack/coffee' somehow, stick this in the Rails initializer config block:

config.middleware.use Rack::Coffee, :root => "#{RAILS_ROOT}/public"

Note however that by default this will not play nicely with javascript_include_tag's :cache option, you would need to compile your .coffee files before deploying. Alternately, check out the BistroCar rails plugin that plays nicely with rails asset handling.

Options

• :root: the directory above urls. Defaults to Dir.pwd.
• :urls: the directories in which to look for coffeescripts. May specify a string or an array of strings. Defaults to /javascripts.
• :static: Whether to serve any static assets found in your urls (via Rack::File). Defaults to true; Specify false to pass through to your app.
• :cache: Sets a Cache-Control header if truthy, public if set to :public
• :ttl: The default max-age value for the Cache-Control header. Defaults to 86400.
• :nowrap: When true, disables the top-level function wrapper that CoffeeScript uses by default.

Bugs?

• Let me know here: Issue Tracking

Requirements

• CoffeeScript and node.js which coffee-script now depends on.
• Rack

Thanks

• Jeremy Ashkenas, for creating CoffeeScript
• Brian Mitchell, for picking up the slack on handling the 0.5 update

History

• March 21, 2010: release 0.3.2

  • added :nowrap option to config, allowing the disabling of the top-level function wrapper.

• March 6, 2010: release 0.3.1

  • options now take :cache and :ttl options for setting cache headers, should you decide to actually serve up hot coffeescripts outside of your development environment. Via Brian Mitchell.

• March 6, 2010: release 0.3 REQUIRES COFFEE-SCRIPT 0.5 OR HIGHER

  • CoffeeScript is now written in coffeescript. The included compiler is now based on node.js instead of being hosted in a ruby gem, so we're shelling out to the command-line interpreter. Thanks to Brian Mitchell for doing most of the dirty work, at least as far as ruby 1.9 is concerned.

• January 27, 2010: release 0.2 BACKWARDS INCOMPATIBLE

  • replace :url parameter in favor of :urls, now it behaves similarly to Rack::Static (Brian Mitchell)
  • add :static parameter, which when false will disable automatic asset serving of url misses via Rack::File, instead passing through to the app.
  • improve documentation for Rails
  • remove dependency on Pathname, oh if only it were stdlib instead of extlib

• January 26, 2010: First public release 0.1.
