Clojurians Log v2

Hey all. I've gone through the really painful journey of migrating from lein -> deps.edn. This included moving from figwheel-sidecar to figwheel-main. I have everything working with the exception of the repl integration with cider (the ui loads as I would expect). It appears that my websocket connection fails in my console with the followin gmessage:

socket.cljs?rel=1562357436120:71 WebSocket connection to '<ws://localhost:3449/figwheel-ws/example>' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

;; dev.cljs.edn
{:main myapp.meow}

;; myapp.meow
(ns ^:figwheel-no-load myapp.meow
  (:require [myapp.core :as core]
            [devtools.core :as devtools]
            [cljs.spec.test.alpha :as stest]))
(prn "doing it meow")
(enable-console-print!)

(devtools/install!)
(core/init!)
(stest/instrument)

interesting. figwheel-ws isn't anywhere in the figwheel-main repo but i see it in lein-figwheel

Interesting... I wonder where it is getting that from

lein-figwheel isn't in my deps.edn, however it is in the project.clj :S

I am booting using deps.edn though

grep for figwheel in the frontend? possible your dev front end reaches out on its own?

don't know where example would come from though

I see nothing:

kvlt@trve [19:07:12] [~/workspace/myapp/src/cljs] [feature/depsedn *]
-> % ag "figwheel"
myapp/meow.cljs
1:(ns ^:figwheel-no-load myapp.meow

Doesn't ws refer to websocket? Does figwheel-main not use websockets?

it does but not at an endpoint with figwheel-ws in it

(as far as i can tell)

This is also super weird:

that's a clj repl that will become a cljs repl when you connect to the frontend

I thoguht as much 😕

and you go to localhost:9500 and see that error?

That seems to load with the text "debux test". Only console error is: GET http://localhost:9500/js/main.js net::ERR_ABORTED 404 (Not Found)

I'm not sure if that is significant

that's super significant. that's you not having a cljs application

so your page is saying load the js from js/main.js and that's not where your compiler is putting it

location of your js: public/cljs-out/dev-main.js but you're asking for it at js/main.js

Ok. That does sound rather important. Would that be a figwheel-main.edn config?

those are compiler settings. i think you want to put those in your dev.cljs.edn file

https://github.com/bhauman/figwheel-main#quick-way-to-understand-the-command-line-options check the output-to and output-dir settings

this should mimic the cljsbuild compiler options from project.clj

OK huge improvement. The repl is connecting, but it's connecting to localhost:9500 rather than my app

Figwheel main is compiling and serving your app. It is your app

If you need to serve your app from your backend look into the docs for how to do that
