Has anyone succeeded in getting https://github.com/fulcro-community/fulcro-exercises/ working for the 0 step with emacs?
When I executed M-x cider-connect-cljs it connects to the shawdow-cljs server and the REPL's namesapce was set to cljs.user. But I when I evaluated
cljs.user> (shadow/repl :main)
------ WARNING - :undeclared-ns ------------------------------------------------
Resource: <eval>:1:2

--------------------------------------------------------------------------------holyjak.fulcro-exercises I got no feedback of success, nor feedback of error.
then when I modified the step 0 as follows:
(do ;; comment ; 0 "Try it out!"
(do
(defsc Root0 [_ _]
(h1 "Hello, I am a Fulcro app from the exercise 0!"))
;; Send this whole `do` to the REPL. Do you see the UI change in the browser?
(render! Root0)
(comment ; try running the hint fn 3 times!
(hint 0)
(hint 0)
(hint 0))
nil))shadow-cljs - [reload failed] Failed to load holyjak/fulcro_exercises.cljs: nil passed to get-query
I found no other error nor feedback.But I am able to get repl working with Cursive. And with Cursive, I can manually execute functions and get the expected behavior at the web page and the repl output buffer. So the problem is just related to emacs of connecting to cljs/shadow-cljs buffer.
Are you sure that cider-connect-cljs does what you expect? I thing what you should actually do is to starta clj REPL connecting to the running shadow repl and then run (shadow/repl :main) from that shadow clojure repl to connect to the cljs REPL. But #shadow-cljs might be a better place to get advice.
Yes, cider-connect-cljs is the command to connect to externally started REPL.
I found a solution. It requires additional dependency to cider.nrepl. Here is the details:

@yubrshen could you be so kind and check whether the updated instructions and deps work for you out of the box? See https://github.com/fulcro-community/fulcro-exercises/pull/3/files (if you have cloned the repo before, then you can fetch and check out the fix/cider-support branch. Thank you!!!
Sure. I'll.
Yes, following your instruction, after starting REPL by
clojure -M:cider:serve
then from emacs with M-x cider-connect-cljs
then, I can evaluate ClojureScript code in the project's source code buffer.
Thanks for a very clearn accomodation!
(In my experiement, cider/piggieback {:mvn/version "0.5.1"} is not necessary.)
On another note, in shadow-cljs.edn, should
:deps {:aliases [:dev]} be
:deps {:aliases [:serve]}
as the required dependencies for shadow-cljs.edn from deps.edn is defined by :serve
I tried to start REPL within emacs M-x cider-jack-in-cljs
It seemed the above fix is needed.
Thanks a lot! Deps: I will just remove the alias, it can perhaps cause problems if it is not defined on your machine (I have it in my global deps.edn). The :serve deps are not required by shadow in my experience.
