font-awesome-rails provides the Font-Awesome web fonts and stylesheets as a Rails engine for use with the asset pipeline.
Add this to your Gemfile:
application.css, include the css file:
/* *= require font-awesome */
Then restart your webserver if it was previously running.
Congrats! You now have scalable vector icon support. Pick an icon and check out the FontAwesome Examples.

When building a Rails engine that includes font-awesome-rails as a dependency,
be sure to
require "font-awesome-rails" somewhere during the intialization of
your engine. Otherwise, Rails will not automatically pick up the load path of
the font-awesome-rails assets and helpers (source 1, source 2, source 3).
Deploying to sub-folders
It is sometimes the case that deploying a Rails application to a production
environment requires the application to be hosted at a sub-folder on the server.
This may be the case, for example, if Apache HTTPD or Nginx is being used as a
front-end proxy server, with Rails handling only requests that come in to a sub-folder
http://example.com/myrailsapp. In this case, the
FontAwesome gem (and other asset-serving engines) needs to know the sub-folder,
otherwise you can experience a problem roughly described as "my app works
fine in development, but fails when I deploy
To fix this, set the relative URL root for the application. In the
environment file for the deployed version of the app, for example
set the config option
MyApp::Application.configure do ... # set the relative root, because we're deploying to /myrailsapp config.action_controller.relative_url_root = "/myrailsapp" ... end
The default value of this variable is taken from
so configuring the environment to define
RAILS_RELATIVE_URL_ROOT is an alternative strategy.
Note: In Rails 3.2, make sure font-awesome-rails is outside the bundler asset group so that these helpers are automatically loaded in production environments.
Versioning follows the core releases of Font-Awesome which follows Semantic Versioning 2.0 as defined at http://semver.org. We will do our best not to make any breaking changes until Font-Awesome core makes a major version bump.
