this is a bit confusing: https://search.maven.org/search?q=figwheel (returns empty results)

hey again, I'm having a hard time wrapping my head around connecting to both a plain clojure nrepl and a figwheel clojurescript repl. I'm using a ring handler as described here: https://figwheel.org/docs/ring-handler.html to write some clojure backend / API. I'm using Cider. I'd like to open a cider repl to the java process, in the same environment that is running the ring middleware, and another to the figwheel clojurescript repl. I finally "succeeded" through this clumsy procedure: 1. Clone https://github.com/dimovich/deps-cider-cljs-reagent 2. Open core.cljs 3. cider-jack-in-cljs, opens a cljs repl, it just works, yay! 4. Ok, now I need the clojure repl. So I found I could do this: :cljs/quit on the cljs repl, now the cljs repl is dead! 5. cider-jack-in-clj, finds the clojure repl started before. Connects! 6. Now I go back to the previous repl and I run: (figwheel.main.api/cljs-repl "dev")The cljs repl is alive again! To be honest I've spent the last whole week trying to open clj+cljs repls from cider... I consider this my break through haha. But I'm sure there must be an easier way! Would appreciate some directions! (I've read the docs a few times but couldn't find specifics of using cider-jack-in-clj&cljs, nor in figwheel-main nor http://cider.mx sites)

Another attempt: I figured I could start an nREPL server with known port for the java REPL and then call figwheel's API to start the "dev" build in the background. I thought it would create an additional nREPL server for the CLJS side, so I could print the repl-env and get a different port to cider-jack-in-cljs with. I WAS WRONG 😛

Hi, I am having trouble getting a ClojureScript REPL up and running with Figwheel Main.

Here is a log of my interaction with the system.

Prompt will show when Figwheel connects to your application

It just sits there at that point

My further actions: > <Browse to http://0.0.0.0:3449/> > <Notice error: ClojureScript could not load :main, did you forget to specify :asset-path?>

:asset-path is there in the configs, but maybe in the wrong place?

At the top of that output it says to run (figwheel/cljs-repl \"app\") in the repl, where app I assume is admin in your case. Did you try that?

It leads to the same result

Sitting there waiting for Figwheel to connect

I've started it a different way now, inside of CIDER -- so that I can get all the dependencies

I don't see the same error in the browser

In fact, I see this: > [http://goog.net.WebSocket] WebSocket opened on <ws://exchange-cljs.test:9500/figwheel-connect?fwprocess=73e2bb&fwbuild=admin&fwsid=c9b0b578-b41a-4b36-bf6d-8e47d1fbd6d2&fwsname=Shelia>

So that suggests to me that the application is indeed connecting to Figwheel

But still on the REPL I have the same "Prompt will show when Figwheel connects to your application" message

Maybe the issue is that Figwheel has already started elsewhere, so my REPL version is superfluous

Is there a way to connect from user> to an existing Figwheel, rather than run (start-figwheel!)?

Aha, I have at least extracted information about it:

I'm not sure what changed
