Clojurians slack (join) has a channel #ring-swagger for talk about any libraries using Ring-swagger. You can also ask questions about Compojure-api and Ring-swagger on other channels at Clojurians Slack or at #clojure on Freenode IRC (mention compojure-api or ring-swagger to highlight us).

Examples

Hello World

(require '[compojure.api.sweet :refer :all])
(require '[ring.util.http-response :refer :all])

(defapi app
  (GET "/hello" []
    :query-params [name :- String]
    (ok {:message (str "Hello, " name)})))

Api with Schema & Swagger-docs

(require '[schema.core :as s])

(s/defschema Pizza
 {:name s/Str
  (s/optional-key :description) s/Str
  :size (s/enum :L :M :S)
  :origin {:country (s/enum :FI :PO)
           :city s/Str}})

(def app
 (api
   {:swagger
    {:ui "/api-docs"
     :spec "/swagger.json"
     :data {:info {:title "Sample API"
                   :description "Compojure Api example"}
            :tags [{:name "api", :description "some apis"}]}}}

   (context "/api" []
     :tags ["api"]

     (GET "/plus" []
       :return {:result Long}
       :query-params [x :- Long, y :- Long]
       :summary "adds two numbers together"
       (ok {:result (+ x y)}))
