+#### Precompiled Component File
+
+The default configuration assumes the asset pipeline is available in all environments.  If you precompile assets for production and want to fetch `components.js` from the precompiled assets, add this additional configuration:
 
+```ruby
+config.react.component_js = lambda do
+  config.react.component_filenames.map do |filename|
+    File.read(Rails.root.join('public', 'assets', filename))
+  end.join(';')

 ## CoffeeScript
 
 It is possible to use JSX with CoffeeScript. The caveat is that you will still need to include the docblock. Since CoffeeScript doesn't allow `/* */` style comments, we need to do something a little different. We also need to embed JSX inside backticks so CoffeeScript ignores the syntax it doesn't understand. Here's an example:
