Clojurians Log v2

Hey, I'm going through the Etudes for Clojurescript book, and would like to know the general consensus now on which parts of the described ecosystem are up to date

for example, the book mentions the libraries (`dommy`, domina, enfocus) but the last commit for these one are ~6 years ago

I don't know the book but that sounds rather outdated. clojurescript hasn't changed much though so those generic parts will still be accurate. Just some libs have changed.

mostly react based these days. so reagent/re-frame/fulcro/etc

I've used dommy and domina a few years ago. Eventually rewrote everything to use clojure.browser.dom where needed.

And there's also goog.dom which clojure.browser.dom itself uses.

thanks! Could you also suggest a library for interactively displaying graphs (by which I mean, DAGs, not charts)? Is binding to d3 the current choice?

I find Vega really pleasant to work with. Theres a project called Oz by metasoarous that wraps it and works on both clojure and clojurescript.

When i switch from clojurescript 1.10.741 to 1.10.773 I started getting this error:

Uncaught Error: find-ns-obj not supported for target bundle

The debug trace isn't particularly helpful:

I don't think you can dynamically created namespaces in a non-boostrapped CLJS.

I thought I was in bootstrapped CLJS?

target bundle says otherwise.

Like, I'm evaluating this with cljs.js/compile.str

I see.

So may I ask why it used to work?

Or was that just some bug that happened to make it work just fine?

Dunno. Seems like the code of find-ns-obj hasn't changed in years. Maybe someone with more knowledge will chime in.

I see.

If you have the time, I would create a minimal reproducible example.

Sure, I can do that.

Okay, I've made a fairly minimal example of this problem: https://github.com/LeifAndersen/cljs-find-ns-example

When you move the comment from line 3 to line 4 (switching from 1.10.773 to 1.10.741) the program works.

(Run lein figwheel and 3 will appear in the browser console.

)

But when you don't, you'll get that error.

Oh, tagging @p-himik again

hmmm. I was able to reproduce the issue (works with one version, but not with the other). there is a #bootstrapped-cljs channel that you can try for issues relating to bootstrapping

fwiw, I was able to get it to "work" with the :target set to nodejs

bash-3.2$ node js/development/app.js                                                                                                           
{:ns cljs.user, :value 3}
