Parse Clojure Script to JSON in Javascript

Question

I have a clojure data in the form of clojure format.

[{:dt [2017 6 30], :cashflow 431782} {:dt [2018 6 30], :cashflow 452271} {:dt [2019 6 30], :cashflow 473785} {:dt [2020 6 30], :cashflow 496374}]

I want the above clojure data in the form json. from clojure side i can always use Cheshire. But I would like tto do it on the lient side in javascript

so on client/js you'd have your data/input as string ? i.e. "[{:dt [2017 6 30], :cashflow 431782} {:dt [2018... and want to parse that ? — birdspider

As illustrated in this question (cljs.reader/read-string) and this (clj->js) the following should do the trick:

cljs.user=> (def data-as-str 
  "[{:dt [2017 6 30], :cashflow 431782}
    {:dt [2018 6 30], :cashflow 452271}
    {:dt [2019 6 30], :cashflow 473785}
    {:dt [2020 6 30], :cashflow 496374}]")
#'cljs.user/data-as-str

cljs.user=> (cljs.reader/read-string data-as-str)
[{:dt [2017 6 30], :cashflow 431782}
 {:dt [2018 6 30], :cashflow 452271}
 {:dt [2019 6 30], :cashflow 473785}
 {:dt [2020 6 30], :cashflow 496374}]

; i have little experience in cljs but this should deliver
; a plain old js object
cljs.user=> (clj->js (cljs.reader/read-string data-as-str))
#js [#js {:dt #js [2017 6 30], :cashflow 431782}
     #js {:dt #js [2018 6 30], :cashflow 452271}
     #js {:dt #js [2019 6 30], :cashflow 473785}
     #js {:dt #js [2020 6 30], :cashflow 496374}]

from here on you could do whatever JSON.___ or other js-json lib provides

for example:

cljs.user=> (.stringify js/JSON 
              (clj->js (cljs.reader/read-string data-as-str)))
"[{\"dt\":[2017,6,30],\"cashflow\":431782},{\"dt\":[2018,6,30],\"cashflow\":452271},{\"dt\":[2019,6,30],\"cashflow\":473785},{\"dt\":[2020,6,30],\"cashflow\":496374}]"

Hey i really appreciate your immediate response. but this you are doing from clojure side. I want to do it on client side like in javascript.

Jared Smith Over a year ago

@SufiyanAnsari that is client side. cljs is clojurescript.

birdspider Over a year ago

nope this is all clojurescript. as you question has a clojurescript tag - I assumed you have clojurescript on the client side

Jared Smith Over a year ago

@SufiyanAnsari writing a reliable parser for even trivial grammars is beyond a "link"... or even the scope of an SO question. I mean you will have to start from scratch. Just use clojurescript on the client. Or serialize to JSON on the server.

@SufiyanAnsari I just spent 4 seconds on google, and found an js/edn parser - good luck :)

You can use EDN parser implemented in JavaScript: github.com/shaunxcode/jsedn.
