 If you wish to run this as part of your existing assets precompilation step, you can add the following into your app's `Rakefile`:
 
 ```ruby
-Rake::Task['assets:precompile'].enhance do
-  Rake::Task["lookbook:previews:preparse"].invoke
+if Rails.env.production?
+  Rake::Task['assets:precompile'].enhance do
+    Rake::Task["lookbook:previews:preparse"].invoke
+  end
 end
 ```
 
 The pre-parsing of preview files will then take place every time `rake assets:precompile` is called and so will not need to be run separately.
