@spangler is it possible that your HTML resource isn't included in the uberjar?

blak3mill3r00:03:43

jar -tvf file_name.jar

blak3mill3r00:03:36

I don't know luminous but that message seems familiar... when trying to mount the root component with reagent to some container DOM node... a <div id="myapp"></div> for example

blak3mill3r00:03:43

and that DOM node isn't there

blak3mill3r00:03:09

it seems like there is no DOM element with the id organism

blak3mill3r00:03:53

maybe try in your javascript console document.getElementByID("organism") ?

spangler05:03:53

Yeah! It's definitely in the jar

spangler06:03:44

Just checked, document.getElementByID("organism") returns the DOM node

spangler06:03:46

Right, so when (rdom/render [#'game-page] (.getElementById js/document "organism")) gets called, that DOM node does not exist

spangler06:03:52

which means it's being loaded at the wrong time?

spangler06:03:40

But that script tag is at the bottom of the body.... I left it there from the original luminus template

spangler06:03:19

as far as I can tell that's where it's supposed to go, and should ensure the DOM is loaded before the script is run

spangler06:03:23

Kind of baffling

spangler06:03:33

Also: only in the uberjar, not in dev

spangler07:03:41

Okay, I fixed it, though I'm not totally sure how

spangler07:03:09

extreme number of layers going on here

william10:03:16

is there a tool you would recommend to explore a cljs codebase in general? I would find helpful a tool that showed me the call graph of a function I'm invoking

anonimitoraf10:03:02

Call hierarchy is supported with clojure-lsp

william10:03:10

thanks @UR37CBF8D! I found the command lsp-treemacs-call-hierarchy, that shows me the hierarchy of who's calling my function successfully (what they call the incoming call hierarchy). The documentation also says that I could get the outgoing call hierarchy (who my function calls) by using the universal argument. But in that case I get the error:

can you use the outgoing call hierarchy successfully in your cljs projects?

anonimitoraf11:03:12

> The documentation also says that I could get the `outgoing` call hierarchy (who my function calls) by using the universal argument How do I do this?

william11:03:33

@UR37CBF8D it depends on your emacs setup: if you are using spacemacs or doom-emacs, you want SPC u M-x lsp-treemacs-call-hierarchy, if you are using regular emacs C-u is used to activate the universal argument, and then trigger the command as you do usually

anonimitoraf12:03:32

Cool Yea, I get an error too

Hi! Hope everyone is well. I'd like to shrink my uberjar that goes into our production deployment, and I just noticed that a decent chunk of the .jar is .class files related to the Google Closure javascript compiler. The fully compiled/optimized .js is already fully built in the jar. Would it make snese/is it possible to not include Google Closure stuff in the final jar?

You shouldn't mix CLJS build and backend classpaths.

p-himik22:03:06

Not only in production, but in dev as well.

That's an interesting thought.

Harold22:03:32

I use lein. Maybe I need to have some profiles (or something) so that the clojurescript dep doesn't end up in the uberjar (!)

p-himik22:03:41

Yep, at least one profile - for CLJS building. Use it without profiles for running the backend and with that profile to build/watch CLJS.

p-himik22:03:05

Of course, it would mean that the CLJS build/watch step will be run on a different JVM.

I believe that is already the case, this project uses fighweel.main with lein trampoline for the local dev env.

Thank you for these very helpful thoughts. 🙇

wow, cut my jar in half @U2FRKM4TW 👏 - I'd like to subscribe to your newsletter.

p-himik22:03:36

:D Just forward the word of separate profiles.

Harold22:03:47

For sure I will! I just cleaned up a bunch of :exclusions / dependency conflicts too. The profiles will be fruitful and multiply.

65% size reduction now.
