Previously I have discussed on how to run a ring app using boot. Here we will see how to run a ring app that uses compojure for routes using boot. We will be using jetty as the server. The difference is that in a pure ring based app, you will pass the ring handler function to the run-jetty method, but here you will pass (compojure.handler/site routes-method) to run-jetty method.

compojure-boot
├── build.boot
└── src
    └── net
        └── jsloop
            └── server
                └── core.clj

;core.clj
(ns net.jsloop.server.core
  (:use compojure.core)
  (:require [ring.adapter.jetty :as jetty]
            [compojure.handler :as handler]))
 
(defn greet []
  "Hello from compojure")
 
(defroutes api-routes
  (GET "/" [] (greet)))
 
(defn run-server []
  (jetty/run-jetty (handler/site api-routes) {:port 8080}))

;boot.clj
(set-env!
  :source-paths #{"src"}
  :dependencies '[[org.clojure/clojure "1.8.0"]
                  [ring "1.5.0"]
                  [compojure "1.5.1"]])
 
(require '[net.jsloop.server.core :as server])
 
(deftask run []
  (with-pre-wrap fileset (server/run-server) fileset))

From the project root, run the server using boot as

boot run

Open http://localhost:8080 to see the response.
