Compojure is an open source web framework for the Clojure programming language. It emphasizes a thin I/O layer and a functional approach to web development.

Compojure is still in active development. The current stable branch has been released as version 0.3.1.

Sample Code

Here's a small web application written in Compojure:

(use 'compojure)

(defroutes my-app
  (GET "/"
    (html [:h1 "Hello World"]))
  (ANY "*"
    (page-not-found)))

(run-server {:port 8080}
  "/*" (servlet my-app))

Dependencies

To run Compojure, you'll need:

• The Clojure programming language
• The Clojure-Contrib library
• A Java servlet container like Jetty
• Apache Commons FileUpload, IO and Codec.

These dependencies can be downloaded automatically using:

ant deps

Documentation

For information on how to get started and use Compojure, please see our Wiki.

There is also a rough draft of a Compojure Tutorial available to read.

Community
