Duct is a asset pipeline package for the Laravel framework. It shares the same philosophy as Laravel, development should be an enjoyable and fulfilling experience. When it comes to managing your assets it can become quite complex and a pain in the arse. These days developers are able to use a range of pre-processors such as Sass, Less, and CoffeeScript. Duct is able to handle the processing of these assets instead of relying on a number of individual tools.
