Sometimes I start up shadow-cljs via M-x cider-jack-in-cljs, but it fails with below output

[:app] Configuring build.
[:app] Compiling ...
shutting down ...

@quest see https://github.com/thheller/shadow-cljs/issues/546

it isn't normal that it is shutting down immediately. so it is likely getting killing by your OS.

could be just because it is running out of memory

or could be for other reasons (eg. anti-virus)

there likely is no exception to log. might also have something to do with cider-jack-in-cljs. not the slightest clue what that does.

@jo.chasinga see https://shadow-cljs.github.io/docs/UsersGuide.html#target-npm-module

a rather old example showing how to integrate in a create-react-app app https://github.com/thheller/reagent-react-integration/blob/shadow-cljs/src/index.js

[thheller/shadow-cljs "2.8.48"] stopped working with Cider. It throws

@malch it only stops working when you use custom stuff 😉

in this case you need to adjust your middleware

https://shadow-cljs.github.io/docs/UsersGuide.html#_embedded_nrepl_server

I changed it and there is only one now

trying now

oh crap .. does cider still have hardcoded references to piggieback?

🤷

I'm so tired of working around that mess 😛

besides, 2.8.48 for some reason changes my :init-ns

to shadow.user

I can stick with 2.8.47 for now, no problem here

please describe the setup you use

the default shadow-cljs.edn only setup shouldn't have changed

as far as custom setups go I make no guarantees

little messy, was testing

oh, yeah just find a bad thing in the nrepl init code

the :init-ns thing was called mistakenly

that looks all ok but where is your cider stuff?

oh, profiles.clj

hmm I must be missing something. where is the cider nrepl middleware being configured?

:profiles {:dev {:source-paths ["dev/clj"]
                   :repl-options {:nrepl-middleware [
                                                     ;; shadow.cljs.devtools.server.nrepl04/cljs-load-file
                                                     ;; shadow.cljs.devtools.server.nrepl04/cljs-eval
                                                     ;; shadow.cljs.devtools.server.nrepl04/cljs-select

                                                     shadow.cljs.devtools.server.nrepl04/middleware
                                                     ]}}
             :uberjar {:aot :all
                       :main rpquest.main }}

:repl-options inside?

thats the shadow-cljs middleware

but where is cider?

:repl {:plugins [[cider/cider-nrepl "0.22.0-beta10"]
                  [refactor-nrepl "2.5.0-SNAPSHOT"]]}

that's all the config I needed

hmm ok. I guess the plugins then add it dynamically

yeah

@malch try 2.8.49. I added back the missing piggieback descriptor I deleted accidentally

sure, trying now

I really need better test cases for this crap

sorry 😉

try 2.8.50

seems to be working, thank you!
