clojurescript - Using defprotocol to create javascript object -

given i've defined protocol

(defprotocol subscriptionlistener   (onconnection [cid] "")   (onupdate [cid data] "")) 

and interacting library in javascript object interface passed in follows

(js/somelib.connect url listener) 

is there easy way create javascript object using defined protocol?

i have tried reify protocol:

(js/somelib.connection "localhost" (reify subscriptionlistener                                       (onconnection [cid] (println cid))                                       (onupdate [cid data] (println data)))) 

however not give object compatible external libraries.

thanks

there conceptual mismatch here. js library expects defined behavior want define cljs. should listener js object 2 methods, onconnection , onupdate? need translator between subscriptionlistener in cljs , regular object in js:

(defprotocol subscriptionlistener   (on-connection [o cid])   (on-update     [o cid data]))  (defn translator   "translates cljs object follows subscriptionlistener     js object has right mehods"   [o]   #js {:onconnection (fn [cid]      (on-connection o cid))        :onupdate     (fn [cid data] (on-update o cid data))})  (js/somelib.connection "localhost"                         (translator (reify subscriptionlistener                                       (on-connection [_ cid] (println cid))                                       (on-update     [_ cid data] (println data)))) 

notice functions in subscriptionlistener take object complies protocol first argument. if cid id given server , tried call (on-connection cid) method on-connection not defined integers.
