Railcar

Client Auto-Reload for Ruby on Rails.

This gem will cause your visitor's browsers to automatically reload when a new release of your Rails app is deployed. This helps ensure that the DOM and JS running in a browser are not outdated.

Railcar achieves this by running as client-side javascript, monitoring the server-side availability of the currently loaded assets. If they are no longer available, Railcar assumes that a new, fingerprinted version has been generated and forces a reload.

Installation

Add this line to your application's Gemfile:

gem 'railcar'

And then execute:

$ bundle

Or install it yourself as:

$ gem install railcar

Finally, require the Railcar logic in your script pipeline (this generally goes in app/assets/javascripts/application.js, after the jquery-related requires):

//= require railcar

That's it!

Usage

If you followed the installation steps, you're done.

Note: Because Rails, by default, only fingerprints assets when running in production mode, Railcar will not run while in development.
