ring.middleware.jsonp

Installation

Add the following to your project.clj :dependencies:

Usage

Wrap your Ring application with wrap-json-with-padding and JSON resources will automatically support JSONP.

Example:

(use 'ring.middleware.jsonp 'ring.util.response)

(def app
  (-> (response "{\"result\": 42}")
      (content-type "application/json")
      (constantly)
      (wrap-json-with-padding))) ; <--

(:body (app {}))
; => "{\"result\": 42}"

(:body (app {:params {:callback "f"}}))
; => "f({\"result\": 42});"

Compojure

If you're using Compojure, make sure wrap-json-with-padding is placed above your site handler (if you have one).

Example:

(def app
  (-> app-routes
      (wrap-json-with-padding) ; <--
      (handler/site)
      ...))
