Questions tagged [sprockets]

Sprockets is a Ruby library that preprocesses and concatenates JavaScript and CSS source files.

Sprockets takes any number of source files and preprocesses them line-by-line in order to build a single concatenation.

Specially formatted lines act as directives to the Sprockets preprocessor, telling it to require the contents of another file or library first or to provide a set of asset files (such as images or stylesheets) to the document root.

Sprockets attempts to fulfill required dependencies by searching a set of directories called the load path.
