@davidcerezoinigo I generally recommend staying away from environment variables for builds since they are typically abused for something that should be runtime configuration to instead be used for build configuration

but you can use the reader macro #shadow/env "THE_KEY" in the config

:closure-defines {some.thing/foo #shadow/env "FOO"}

run into several issues when I was introducing shadow-cljs to my friend today. not confirmed. 1. when :target :node-script is used with :modules {:main {:init-fn a.b/c}}, I saw no warnings on running shadow-cljs.edn. 2. ":after-load x.y/reload" is written in the configs while the real namespace is a.b/reload, 3. I added ["fs" :as fs] and save file, is how replaces and import fs. however it throws an error. restarting the process then it will be ok.

@jiyinyiyong I don't understand what you mean with 3.? what error does it throw?

didn't note down that error.

something looked like couldn't find that namespace

I'm gonna need a full error report and preferably reducible example. I'm not going to try and guess what you were seeing

1/2 are known. Configs need more validation.

okay. I would copy the error messages next time I see it.

hello! I'm trying to do the free reagent course but using emacs/cider instead of atom. can someone please take a look at the project's shadow-cljs.edn file and help me switch out proto-repl so that I can use cider. I keep getting errors when trying to connect the repl about my middleware. https://github.com/jacekschae/learn-reagent-course-files/blob/master/giggin/shadow-cljs.edn

@chase-lambert you just take out the proto-repl and add cider-nrepl with the version matching your cider config

i thought that was it but maybe i'm using the wrong version. let me find out how to check my cider config

does it not tell you on connect? I thought it used to

there are some instructions here but I don't know how current they are. cider seems to be changing a lot. https://shadow-cljs.github.io/docs/UsersGuide.html#cider

do i want to use shadow or shadow-select if I've already got the server running?

cider does change a lot! I also failed to set my config to only use cider stable. this tech game is hard for me this week!

not sure I understand what you mean by "shadow or shadow-select"

ahh. when you connect-cljs in cider it asks for host, port, and then Clojurescript repl type. it has two options for shadow-cljs. shadow and shadow-select. Then it also asks for build type so I select dev and it gives me this error:

WARNING: No Clojure project was detected. The
refactor-nrepl middleware was not enabled. (You can mute this

shadow.user> ExceptionInfo no build with id: :dev  clojure.core/ex-info (core.clj:4739) 

the build is called :app if you are using the default giggin config

https://github.com/jacekschae/learn-reagent-course-files/blob/master/giggin/shadow-cljs.edn#L10

hmmm, ok. still didn't work but it's a little different. Cider is telling me this: CIDER 0.20.0snapshot (package: 20190112.721), nREPL 0.4.5 but if I put that in the dependencies instead of [cider/cider-nrepl "0.19.0"] I get a dependency error when starting the server

put in what?

WARNING: No Clojure project was detected. The
refactor-nrepl middleware was not enabled. (You can mute this
warning by customizing `cljr-suppress-no-project-warning'.)
shadow.user> To quit, type: :cljs/quit
[:selected :app]
cljs.user> 

that looks correct now?

but it says shadow-cljs - connection closed still on the browser. what's a simple expression I can throw in the repl to see if it's working? something like (js/alert "It's working!")?

it probably still fails to connect due to your strange VM setup

the browser is trying to connect to the shadow-cljs process via websocket

oh. damn that is frustrating. I have it open in both my linux "container" and my regular os.

and that likely is the problem here

open the browser console and check what it says

wait it worked! It is in my linux browser but the bottom left corner is just blank instead of the green shadow-cljs connection open or whatever I thought it would be. Sweet!

thanks again for helping me out. I know i'm probably making things overly difficult. But boy howdy is it frustrating to not even be able to get set up. I'm learning though.

can't comment on cider anymore. I quit using it a long time ago, got too tired of it breaking 😉

what do you use now?

I’m getting a compile warning

this is during a release build

this is with infer externs / npm package react-transition-group and doing the cljsjs hack of (js/goog.exportSymbol "ReactTransitionGroup" react-transition-group) (we’re still migrating …)
