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>"))
