I have a project which runs perfectly when I use watch app but when I release with release app it gives some failed to loaderrors. How can I solve such problem.

thheller07:05:34

which shadow-cljs version is this with? I fixed a couple issues regarding $jscomp not too long ago

thheller07:05:21

otherwise the easiest way to fix this increasing the :compiler-options {:output-feature-set :es6} or even higher :es7, :es8

thheller07:05:30

depending on how many really old browsers you need to support

thheller07:05:53

in the older versions it was sometimes enough to delete the .shadow-cljs/builds cache

metehan23:05:35

I had "shadow-cljs": "^2.8.51" looks like I am far behind the current version. I don't need to support any old browser so I will just start to use latest version thank you

using latest version and deleting builds solved my problem

Sorry if this is an inappropriate channel but I am wondering how I can debug an import error. I am using luminus with the +shadow-cljs setting. I've added d3-dag to my :npm-deps in project.clj. I've also tried installing d3-dag manually from the command line. However, when I try to require it like this: 

(require '["d3-dag" :as d3])
I get the error: 
[:app] Compiling ...
[:app] Build failure:

Any hints on how to start debugging this would be appreciated. The error is specific to the d3-dag package, since requiring ["react" :as r] works.

@endrebak85 that is cased by a dependency conflict on the closure-compiler version. see https://shadow-cljs.github.io/docs/UsersGuide.html#failed-to-load

Endre Bakken Stovner16:05:16

Thank you. I was experiencing some other weirdness too (dunno if they are due to shadow-cljs though). Will fix it and see if they disappear. Do you think these error messages might have the same cause? https://clojurians.slack.com/archives/C053AK3F9/p1620220881170500

thheller16:05:56

@endrebak85 that happens when you use a too old shadow-cljs version with jdk15+, need to upgrade shadow-cljs

thheller16:05:27

cant' remember which version added jdk15 compatibility, but at least 2.11.x is likely required. current is 2.12.6
