Compojure routes with different middleware

(defroutes user-routes*
  (GET "-endpoint1" [] ("USER ENDPOINT 1"))
  (GET "-endpoint2" [] ("USER ENDPOINT 1")))

(def user-routes
     (-> #'user-routes*
         (wrap-basic-authentication user-auth?)))

(defroutes admin-routes*
  (GET "-endpoint" [] ("ADMIN ENDPOINT")))


(def admin-routes
     (-> #'admin-routes*
         (wrap-basic-authentication admin-auth?)))

(defroutes main-routes
  (ANY "*" [] admin-routes)
  (ANY "*" [] user-routes)

This will run the incoming request first through admin-routes and then through user routes, applying the correct authentication in both cases. The main idea here is that your authentication function should return nil if the route is not accessible to the caller instead of throwing an error. This way admin-routes will return nil if a) the route actually does not match defined admin-routes or b) the user does not have the required authentication. If admin-routes returns nil, user-routes will be tried by compojure.

Hope this helps.
