rack-combobot Build Status

Asset combinator for rack

Installation

gem install rack-combobot

Path

Point your frontend to /combobot?script1.js&script2.js to get script1.js and script2.js combined.

Usage in Rack apps (config.ru)

require 'rack'
require 'rack-combobot'
require 'my-app'

use Rack::Combobot, :root => '/public'
run MyApp

Usage in Rails apps

In your config/application.rb

config.middleware.use 'Rack::Combobot', :root => "#{Rails.root}/public"

Expires header

Add expires header

config.middleware.use 'Rack::Combobot', :root => "#{Rails.root}/public", :expires => Time.gm(2020)

To bust the cache, simple add a unique string to your request like so /combobot/BUSTINGSRING?script1.js&script2.js.

Without query string

If you environment doesn't allow having the file names in the query string (Like on CloudFront). Combobot will accept the file names as part of the url, but they have to start with &.

Something went wrong with that request. Please try again.
