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.

There are also some helpers (
fa_stacked_icon) that make your

When building a Rails engine that includes font-awesome-rails as a dependency,
be sure to
require "font-awesome-rails" somewhere during the initialization 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.
In addition you need to indicate the subfolder when you precompile the assets:
RAILS_ENV=production bundle exec rake assets:precompile RAILS_RELATIVE_URL_ROOT=/myrailsapp
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.
