Clojurians Log v2

Is there a good way to develop shadow-cljs locally and use in other projects? Like lein install, except if you want to use it the recommended way (npm)?

I just lein install

the recommended way still just uses the installed version in .m2 so that has nothing to do with it

what do you intend to do? another way is just putting the shadow-cljs src/main into the source paths of your project

I'm playing with monorepo multiproject multibuild settings and I'm getting a fresh error. I'm not sure where I went wrong with deps.edn alias:

:dev-cljs
  {:extra-deps {thheller/shadow-cljs          {:mvn/version "2.11.22"}
   ...
   :main-opts  ["-m" "shadow.cljs.devtools.cli" "watch" "ui"]}

{:ui {:target :browser
       :output-dir "projects/ui/public/js"
       :asset-path "projects/ui/js"
       :module-hash-names false
       :modules {:ui {:init-fn ui.main/init!
                      :preloads [devtools.preload
                                 day8.re-frame-10x.preload]}}
       :dev {:compiler-options {:infer-externs :auto
                                :closure-defines
                                {re-frame.trace.trace-enabled? true
                                 day8.re-frame.tracing.trace-enabled? true}}}
       :devtools {:repl-pprint true
                  :preloads [shadow.remote.runtime.cljs.browser]
                  :http-root "projects/ui/public"
                  :http-port 8280}}}

@jasonhlogic first of all your :asset-path looks incorrect. likely that should just be /js?

the error you get is when the files you are loading were not produced by the running shadow-cljs instance

so likely if you changed some paths or so you have some older files still somewhere that are not used instead of the new output

or you jsut haven't started the watch? don't know which command you run

I changed the :assset-pathto "/js", but I still get the same error. My command is:

clojure -M:defaults:ui:dev-cljs

{:extra-deps {ui/ui {:local/root "projects/ui"}}}

not a clue how that works but it doesn't matter for shadow-cljs

you are opening http://localhost:8280 I presume?

that serves the files from <project>/projects/ui/public

Confirmed.

Also correct.

and you are including <script src="/js/ui.js"> in the HTML

do you maybe have two instances of shadow-cljs running?

Yes, this app ran before I changed the paths

simple test. shutdown shadow-cljs and open the http://localhost:8280

if you still get a reply then find out from where

Only one instance running, and these resuts are confirmed by another developer

could be a service worker if you have one

I shut down the instance and the browser says it can't connect

ok

then I'm out of ideas. there really isn't much that goes into this. shadow-cljs places the files in the :output-dir and the :http-root serves them

but especially if you move some files or change directory names or so

it is easy to miss one place and is still using an old file from some other directory

yes, let me go clean those out.

you can also remove :preloads [shadow.remote.runtime.cljs.browser]. that has been the default for a while now.

but that doesn't affect anything regarding this

happy to clean out old opts 🙂

i found it. i changed the build name to 'ui' but did not update the name of the js file the index page loads. Thank you very much for your responses. I'm sorry to have taken your time with my config error.

the build name doesn't affect this. the :modules key does.

duly noted and thanks again
