Singapore Clojure Meetup tomorrow night, welcome to join. https://www.meetup.com/Singapore-Clojure-Meetup/events/240601551/

For testing cljs during CI is this a good way to go https://github.com/bensu/doo ?

Is it possible to globally intercept http requests/responses in https://github.com/r0man/cljs-http/ ? Is there any other cljs lib provides that

Hello, is there some trick to getting debugf from timbre working in node.js now? infof works, and debugf was working a few weeks ago for me.

@theasp guessing here...

(set! js/console.debug js/console.log)

What’s a good way to mock out external javascript libraries during unit tests?

@pesterhazy Awesome, that did it, thanks!

My question is pretty ambiguous. I’ll give a more concrete example. I’m trying to test a function that calls a js library like so (.view obj {}). In Clojure, I would use

(defprotocol Viewable
  (view [v]))
(defrecord SpyViewable [called]
  Viewable
  (view [_] "viewed"))

(.view (SpyViewable. {}))

In this example, in ClojureScript, I cannot call the view fn with the dot notation .view.

Is there a way to do this in ClojureScript?

are you trying to call the method of a javascript object?

@tankthinks

(let [o (reify Object (view [x] :hmm))]
  (.view o))

thanks @rauh

You can also say (deftype X Object (view [x] ...)).

there really needs to be a meta-guide on javascript objects and clojurescript objects/protocols and the mechanics of their relationships

Re testing clojurescript apps - are there any recommendations along the lines of karma or something ?

That would definitely help me @bhauman, though I must admit that I know the JVM better than JavaScript, so I may just be ignorant of the details.

@len, I currently use https://github.com/bensu/doo

thanks @tankthinks

It abstracts out the JS environment; that way you can run on phantom, slimer, chrome, etc

aaah right

thats useful, will dig in

it’s a good place to start

Hi, I've been scratching my head for a while already with this one, it's an extern / umd related problem - how to use a webpack compiled library (umd) in cljs? I posted the question with code samples on SO: https://stackoverflow.com/questions/44893233/using-webpack-compiled-library-as-external-in-cljs

Hi there, I am wondering if someone knows a way to jsonify a data structure that contains namespaced keyword into json that keeps the namespaced in the strings. clj->js only keeps the name of the keywords.

Hello is there a channel for newbies to get some help? 🙂

@len we use Karma directly for CLJS testing in CI

https://github.com/Day8/re-frame-http-fx/blob/master/test/day8/re_frame/test_runner.cljs is a good example

@dohxis I use here... we are all newbies in a way or in another

I am just playing around with clojurescript and I am trying to do something strange and I dont even know if its possible. Here is a little example what I am trying todo

that is cool!

you should use partial function

https://clojuredocs.org/clojure.core/partial

it should end up in something like

(def functions {:increment (partial inc) :defrement (partial dec)})

((get functions :increment) 1)
=> 2

wauw thanks that really worked! 😃

my turn to ask a newbie question, why does some variable are surrounded by asterisks. for instance *anti-forgery-token* in some ring modules.

I guess this answers your question https://stackoverflow.com/questions/1986961/how-is-the-var-name-naming-convention-used-in-clojure

@dohxis is does, thanks!
