Compojure is a small routing library for Ring that allows web applications to be composed of small, independent parts.

Add the following dependency to your deps.edn file:

compojure/compojure {:mvn/version "1.7.2"}

Or to your Leiningen project file:

[compojure "1.7.2"]

This small Compojure application demonstrates creating a Ring handler from two routes:

(ns hello-world.core
  (:require [compojure.core :refer :all]
            [compojure.route :as route]))

(defroutes app
  (GET "/" [] "<h1>Hello World</h1>")
  (route/not-found "<h1>Page not found</h1>"))
