;core.clj
(ns qlambda.server.core
  (:require [ring.adapter.jetty :as jetty]))

(defn handler [req]
  {:status 200
   :body "Hello World"})

(defn -main [& args]
  (jetty/run-jetty handler {:port 8080}))

;boot.clj
(set-env!
  :source-paths #{"src"}
  :dependencies '[[org.clojure/clojure "1.8.0"]
                  [ring "1.5.0"]])

(require '[qlambda.server.core :as server])

(deftask run []
  (with-pre-wrap fileset (server/-main) fileset))
