Anyone know how I'd access react-dom/test-utils if i have access to react-dom?

I realize I may be asking the wrong question here; I have reagent in dependencies, which has cljsjs.react-dom in its dependencies, and I can access ReactDOM from the REPL

Yes, interesting. I’m using rum and have the same issue.

The extern files suggest js/ReactTestUtils should work.

I'm kind of getting the feeling that I should be using browserify...

but on the other hand it seems a little ridiculous; TestUtils is right there in react-dom.inc.min.js

I have to go @zentrope, but lmk if you find anything

I wonder if the cljsjs packaging is the issue.

When using rebel-readline is there a way to eval the whole form even when the cursor is in the middle of the form?

@dchristianbell I’m stumped. I looked at deps.cljs in the react-dom jar and tried requiring those namespaces at the figwheel repl, but no js/ReactTestUtils.

@dchristianbell However, in my main.cljs file, I could: (ns my.main (:require [cljsjs.react.dom.test-utils])) and then access the object in a function.

@dchristianbell And once I did a lein figwheel with that declaration, I could reference js/ReactTestUtils in the repl.

So, when using cljsjs libs, look at the deps.cljs in the jar and see if that clues you in. I hope I remember that myself. ;)

Does anybody else here have trouble using the externs generator here? https://jmmk.github.io/javascript-externs-generator/

Hi, is anyone using maps a lot with re-frame? Is there a good alternative for CLJS to leafletJS?

hi, can someone help me what is the best way to deal with promises in cljs

(let [axios (js/require "axios")]
  (doto (.get axios "")
    (.then (fn [resp]
             (js/console.log "resp: " resp)))
    (.catch (fn [err]
              (js/console.log "err: " err)))))

but allways getting: (node:26933) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 8): Error: Network Error

the error is logged correctly on the console tho

but that warning also

@brunex This should help: https://stackoverflow.com/questions/40500490/what-is-an-unhandled-promise-rejection

hmmm

not really, I guess what I need is some example of cljs code how to catch a promise error without that warning

how can I convert strings to ints? parseInt is weird.

what's weird about parseInt? you can use read-string but beware that it will also read anything that's valid cljs

@brunex don't use doto use ->, reject should be a second fn param to .then

thanks!!!

worked

parseInt is definitely weird if you forget to specify the radix. then it behaves like it is possessed.

@joelsanchez parseInt("99aa") = 99, and it returns NaN

What's the 'supported' way of compiling CLJS these days? lein cljs-build ?

supported by who? lein cljsbuild is a tool that uses lein, most things use clojurescript.jar in some way or another, there's a couple things out there that do self-hosted cljs

Well, perhaps "preferred" is a better term

I got the impression that the world had moved on from lein-cljsbuild

that is, lein cljsbuild is a thing that uses lein to run cljs.jar to compile your cljs - figwheel gives an awesome interactive development experience (can run via lein or boot)

that also uses cljs.jar

@acron: my team uses lein figwheel during dev, and lein cljsbuild to make js to deploy, I think that's very common

Ok, fair enough, thanks

We use that also

if you didn't know, the latest figwheel has an amazing repl with colorization and docs and multi line editing

Hello guys! I wanted to decide whether I make a single project for both server/api + client/ui or whether we make two separate. What are you thoughts about this?

Couldn’t find anything on Google in that regard yet

thanks!

You can do so in a single project

any thoughts on why? Any rationale?

in my experience working with a team, with a less disciplined group having separate repos for the frontend and backend leads to chaos and friction

i misread your question; I thought you were just asking if you could. Depending on how tightly the two are coupled, it's probably just less overhead to keep them together

to me it comes down to dev workflow - which would be worse, not knowing if your front and backend versions match (eg. can your team keep things flexible and compatible?) or having frequent merges in one codebase for totally unrelated work

the more disciplined / careful the coding style, the more an advantage to separation

Thanks @noisesmith

Thanks @dchristianbell

Other question, not related: is :npm-deps for clojurescript on the server (node) or it can be used for requiring frontend js library like react-modal, etc. with regular clojure/java backend?

@leontalbot I think it can be used for both, the caveat is that it is very very experimental

oh ok I see

Thanks! @richiardiandrea

is there a codepen like thing for clojurescript where you can share working demos? preferably with the ability to import libraries like reagent
