Clojurians Log v2

I'm using the new bundle option with the cli -w src and getting:

Change detected, recompiling ...
java.lang.AssertionError: Assert failed: :nodejs target with :none optimizations requires a :main entry

fwiw, I do have a :main option.

Ah, easy one. add-implicit-options changes the target to be :nodejs, and that is what is validated against, instead of what I actually used. Should the watch option be usable with :bundle?

seems like the quickstart guide's sample node application is broken on 742 right now. https://clojure.atlassian.net/browse/CLJS-3237

@dominicm need more information, what is your full command?

@dnolen clj -m cljs.main -co build.edn -w src -c -r with:

{:main io.dominic.hxadapound.core
 :output-to "out/index.js"
 :output-dir "out"
 :target :bundle
 :bundle-cmd {:none ["npx" "webpack" "--mode=development"]
              :default ["npx" "webpack"]}}

@dominicm looks fine, can you file a JIRA w/ just that config? thanks - fine to mark major

Yep

@dnolen 1.10.742 appears to be missing from versions on jira

CLJS-3238 🙂

thanks!

@dnolen I'm also getting a similar error - missing main file for nodejs - when trying to use :modules. I also tried adding :nodejs-rt false to no avail. Is combining :bundle with :modules an intended use-case?

@john :bundle + :modules is not expected to work (because not tested, not intentionally) and no specific timeline for when it will

if somebody wants to work on that be my guest - it should not be very difficult

Yeah I might take a look

I guess a JS person in NPM land is already juggling a few other loaders

I'm looking at the main issue today so at that won't obfuscate the problem if there is one

k cool

@john :re codesplitting it should just be kept simple if there any issues

but the idea is that code splitting the node_modules beneath the top-level stuff is impractical

we just don't care about that

the current module graph algorithm can tell us where the top level should go

so it should be roughly ok - then you run the bundler on each of your outputs

K

anyways code splitting is definitely meant to work with bundle - but I'm happy to see somebody else work on it

I mean I'll try, but the JS stuff is still a little alien to me. If nothing else I'll try to get the ball pushed down the road a bit.

@john let's see if you get further when I fix this other problem

Okay. You want a ticket for this module/bundle issue? Or just wait?

Just wait since it’s not clear

@dominicm master is fixed

@john fixed a few things - not sure if it will matter for the :modules stuff happy to take a report now

@dnolen I'll give it a spin :)

@dominicm I also included :stderr which should help w/ failures

you probably want --no-color in your webpack command to make that slightly easier to look at

@dnolen okay

@dnolen that works great, thanks

> This also means you can start a node REPL now with clj -m cljs.main -t node -r big fan of not needed --re if you set the target. i mixed that up a few times and its always confusing for a second

@dpsutton yeah

Where did you get the quote?

commit message for the fix for https://clojure.atlassian.net/browse/CLJS-3237 https://github.com/clojure/clojurescript/commit/6c3276e3248c7e1b9fa3a6d00cffe77ad2860853

I reviewed the AOT cache stuff, I forgot how little code is involved

https://clojure.atlassian.net/projects/CLJS/issues/CLJS-3240

would be quite significant boost for dev builds

esp since it means you can blow away :output-dir and still get a quick build

also for switching between dev/advanced

I'd advise caution for anything AOT cache related and sharing between dev/advanced

there are plenty of macros that will emit different stuff based on compiler settings the compiler does not account for when checking caches

AOT cache doesn't share

but also this will behind a flag

> also for switching between dev/advanced

and it won't be on by default - just for people who know it will work

I guess I misinterpreted that then

:aot-cache is only enabled for cljs.main

re: macros that are problem - that the point of the flag
