I've previously gotten Emacs + Cider + regular Clojure (not cljs) all up and running for my 1st ever Clojure project. I went with Emacs since I had some experience with it 25 years ago. Anyhow, I got the jist of REPL development.

Now I'm trying Clojurescript, to implement the client-side of my little learning project. FWIW I'm trying the "Learn Reagent Free" course at https://www.jacekschae.com (free plug). WELL...

I'm having trouble getting the REPL going in this setup. The online course supplies the basic config files, so most of what I have was provided. Here's my shadow-cljs.edn:

your best bet here is #cider - it's a package with a lot of features and complexity, and the things that go wrong with it don't generalize to other stuff

Using the npm run dev command, it spins up shadow-cljs and starts up nREPL on port 3333.

I run cider-connect and give localhost / 3333, and emacs/Cider connects to the REPL. GREAT. The problem (or my confusion) starts here:

doing any sort of "eval" of any forms, buffers, or anything in Emacs seems to just... do... nothing.

I can enter expresions in the REPL buffer (+ 3 4) yields 7, so the REPL is there. But it doesn't seem "connected" to any of my .cljs files or anything.

So i'm just kinda lost.

Another point: when I was just doing Clojure, I used cider-jack-in to start the REPL. With this shadow-cljs it seemed I had to use cider-connect; perhaps this line of thinking is wrong & is the problem?

When I try to do cider-jack-in, Emacs gives the error The npx shadow-cljs executable isn't on your 'exec-path'

Thanks @U051SS2EU I'll try that channel.
