radio's Introduction

Radio

HTTP RPC server and client. Serializes argument and return values using pr-str and the clojurescript reader. Provides role-based authorization using the ring session map. More information in code doc-strings and comments.

Synopsis

Server functions:

(ns rpc.functions
  (:use me.panzoo.radio.server))

(defrpc :any hello [a b]
  (str "Hello " a ", and " b "."))

(defrpc :admin secret []
  {:secret ["data" 1]})

Server:

(ns rpc.server
  (:use
    me.panzoo.radio.server
    ring.adapter.jetty))

(defn handler [req]
  (if (= "/rpc" (:uri req))
    (rpc-handler (ns-publics 'rpc.functions))
    (handle other requests)))

(run-jetty handler :port 3000)

Client:

(ns rpc.client
  (:use
    [me.panzoo.radio.client :only (*rpc-url* *xhr-pool*)])
  (:require-macros
    [me.panzoo.radio.client.macro :as radio]))

(defn callback [err ret]
  (.log js/console
        (if err
          (pr-str "error " err)
          ret)))

(radio/call (hello "World" "Mum") callback)

(radio/call (hello "World") callback)

(radio/call (secret) callback)

(radio/call (non-existent 1 2) callback)

Console:

"\"Hello World, and Mum\"" ;; 200

"error :server-error"      ;; 500

"error :unauthorized"      ;; 401

"error :unresolved"        ;; 501
