@mike.j.cusack also to see fn bodies at the REPL, try

(set! *print-fn-bodies* true)

=> (set! print-fn-bodies true) => + #object[cljs$core$PLUS “function cljs$core$PLUS(var_args){ var G__10823 = arguments.length; switch (G__10823) { case 0: return cljs.core.PLUS.cljs$core$IFn$_invoke$arity$0(); break; case 1: return cljs.core.PLUS.cljs$core$IFn$_invoke$arity$1((arguments[(0)])); break; case 2: return cljs.core.PLUS.cljs$core$IFn$_invoke$arity$2((arguments[(0)]),(arguments[(1)])); break; default: var args_arr__9263__auto__ = []; var len__9238__auto___10825 = arguments.length; var i__9239__auto___10826 = (0); while(true){ if((i__9239__auto___10826 < len__9238__auto___10825)){ args_arr__9263__auto__.push((arguments[i__9239__auto___10826])); var G__10827 = (i__9239__auto___10826 + (1)); i__9239__auto___10826 = G__10827; continue; } else { } break; } var argseq__9264__auto__ = (new cljs.core.IndexedSeq(args_arr__9263__auto__.slice((2)),(0),null)); return cljs.core.PLUS.cljs$core$IFn$invoke$arity$variadic((arguments[(0)]),(arguments[(1)]),argseq_9264__auto__); } }“]

Hello There, [Clojure Newbe] I need help with this function, I have function in cljs for react frontend, it renders list of item from keys. I want to use if statement to check if key exists but when I use this following code to log the if statement , it by passes the if statement. Please Help! 🙂

(defn parse-list [data]
        (map (fn [[k v]]
              (if (k = "Yesterday") (println "found")) 
                ($ List (name k))
             data))

Replace (k = "...") with (= k "...").

Also, when is usually better in such cases.

also, looks like you are missing the end parentheses and looks like data should be moved out of the current parentheses

Nah, the parens are alright. It's the indentation that's misleading.

thanks guys it worked

Can someone with a better understanding of the "why"s of Clojurescript answer this for me? As a fairly new CLJS user, I'd expect to have the browser and JS APIs fully available to me, but after some research today I discovered that the document.cookie API seems to be read-only in CLJS. In vanilla JS you can both read and set a cookie with the same API:

document.cookie // gets cookies
document.cookie = "key=value" // sets a new cookie

js/document.cookie ;; gets cookies

(ns some-namespace)
(:require [goog.net.cookies])

(.set goog.net.cookies "key" "value")

It's not the biggest problem in the world or anything, but it's got me wondering if there are other areas of JS <-> CLJS interop where I'm going to encounter similar situations.

https://cljs.info/cheatsheet/ check out the js-interop section for getting and setting

that being said, those goog libs are a really nice set of libs that if they offer stuff it can really help you

Cool, I appreciate it @dpsutton! I'll experiment with set! and see if I can get something working just so I can deepen my knowledge on the subject.

Yep, it was exactly what I needed:

(set! (.-cookies js/document) "key=value")

Which styling solutions are you guys using these days for CLJS?

Apparently, you can also do it like this:

(set! js/document -cookies "key=value")

Hi, I use https://github.com/noprompt/garden

And how do you handle being mobile-friendly?

I use cordova for mobile.

And for the mobile-oriented styling I use some custom routines that help me to maintain CSS for portrait/landscape/fullscreen orienations. It's on top of garden.

Finally got around to aligning w/ the latest Closure Compiler and a more recent snapshot of Google Closure Library

if you're comfortable using ClojureScript directly via git deps - please give it a spin

what's on master will probably be the next release

Ah, ok. I'm trying to avoid custom for that

I've been enjoying my emotion wrapper: https://github.com/dvingo/cljs-emotion

I'm looking for a data-driven approach rather than macros.

Tailwind, works great.

I'm curious why there isn't a cljsjs package for that.

The styles in that emotion lib are plain data - you can compose them however you like
