pjax for rails and rack applications

Rack-pjax travis

Rack-pjax is middleware that lets you serve 'chrome-less' pages in respond to pjax-requests.

It does this by stripping the generated body; only the title and inner-html of the pjax-container are sent to the client.

While this won't save you any time rendering the page, it gives you more flexibility where and how to define the pjax-container. Ryan Bates featured rack-pjax on Railscasts and explains how this gem compares to pjax_rails.



Check out the Railscasts' notes how to integrate rack-pjax in your Rails 3.1 application.

You can find the source from the screencast over here.

Another sample-app: the original pjax-demo but with rack-pjax onboard can be found in the sample-app branch.

The more generic installation comes down to:

I. Add the gem to your Gemfile

# Gemfile
gem "rack-pjax"

II. Include rack-pjax as middleware to your application(-stack)

require ::File.expand_path('../config/environment',  __FILE__)
use Rack::Pjax
run RackApp::Application

III. Install jquery-pjax. Make sure to add the 'data-pjax-container'-attribute to the container.

  <script src="/javascripts/jquery.js"></script>
  <script src="/javascripts/jquery.pjax.js"></script>
  <script type="text/javascript">
      $(document).pjax('a', '[data-pjax-container]')
  <div data-pjax-container>

(For more see the docs of jquery-pjax.)

IV. Fire up your pushState-enabled browser and enjoy!
