Useful Libraries

Luminus aims to provide solid defaults for creating your web application. As such it comes packaged with several libraries by default. These libraries include Buddy for security, Bouncer for validation, Selmer for HTML templating, Tower for internationalization and a few others. Of course, there are many other Clojure libraires for web development. Here we are going to provide a list of Clojure and ClojureScript libraries which can be useful in addition to those already included with Luminus.
