hey everyone! I’m starting out with cljs (done a fair amount of clojure though), and hitting a wall when trying to load a foreign lib

No such namespace: hdom, could not locate hdom.cljs, hdom.cljc, or JavaScript source providing "hdom" in file src/hello_hdom/core.cljs

  1  (ns ^:figwheel-hooks hello-hdom.core
                                ^---
  2    (:require
  3     [goog.dom :as gdom]
  4     [hdom :as hdom]))
  5
  6  (println hdom)

https://github.com/dazld/hello-hdom/blob/master/project.clj

the config … looks right?

@dazld did you include hdom in your :npm-deps ? Usually it is in dev.cljs.edn. Note also that this is not the recommended way of importing js anymore as cljs core suggests to use webpack

that was the first thing I tried, but think it was just in the wrong place

however - all is ok, as got some great pointers from people on hash clojurescript

could you point me to where webpack is the current suggestion?

@dazld https://clojurescript.org/guides/webpack

I would also recommend checking http://shadow-cljs.org/ as a layer on top of the compiler (like figwheel-main, but more npm friendly)

thanks, that's interesting

picking apart what each bit is doing especially

wonder if webpack is strictly necessary there, for example...

Well interesting but used to be better to have one tool only IMHO. Now non-JS users need to learn webpack - my 2c

@dazld check this demo repository for rationale and howto aspects of using webpack with cljs: https://github.com/pesterhazy/cljs-spa-example

(hi Dan btw!)

hey! :)

and cool, will do

@pesterhazy just got that project working with the latest CIDER: very nice 👌, thanks!

@eval2020 cool! did you have to change the configuration in any way?

while fiddling around, I upgraded fw-main in deps.edn, but not necessary I assume

one tricky thing: after selecting the ClojureScript REPL type it asks Select figwheel-main build (e.g. :dev):. You should not accept the default (`:dev`), but answer dev

did you have to add anything to deps.edn?

nope

M-x cider-jack-in-cljs and go

cool, maybe I should add that to the README

just did a fresh clone to reproduce: - run ./script/dev - kill this process after bundle got build - M-x cider-jack-in-cljs - select figwheel-main - Select figwheel-main build, type dev - visit http://localhost:9333 - cljs prompt appears

if script/dev could start an nrepl-server, just a cider-connect would suffice - not sure if that’s possible

possible as an option to figwheel-main

cool

yeah I think cider preforms some magic to add in the necessary nrepl middleware

that's pretty clean, but not sure if other repl clients can do the same

Is it possible to set a custom initial namespace with figwheel-main? I.e. rather than cljs.user

re CIDER interop. After some experiments I ended up with simple set-up to start fig manually and then cider-connect: deps.edn:

{:paths ["src/cljs" "target"]

 :deps {org.clojure/clojure       {:mvn/version "1.9.0"}
        org.clojure/clojurescript {:mvn/version "1.10.339"}}

 :aliases {:fig {:extra-deps {cider/cider-nrepl {:mvn/version "0.18.0"}
                              cider/piggieback  {:mvn/version "0.3.9"}

                              com.bhauman/figwheel-main       {:mvn/version "0.1.9"}
                              com.bhauman/rebel-readline-cljs {:mvn/version "0.1.4"}}}

           :bs {:extra-paths ["."]
                :main-opts   ["-m bootstrap"]}}}

(ns bootstrap
  (:require [figwheel.main.api]
            [cider-nrepl.main :as cider]))

(defn -main [& args]

  (cider/init ["cider.nrepl/cider-middleware"])
  (println "*********************")

  (figwheel.main.api/start "dev"))

(figwheel.main.api/cljs-repl "dev")

if you prefer to customize cider this is one example I found which might help https://github.com/arichiardi/figwheel-main-cider/blob/master/.dir-locals.el

I should actually fix the keyword issue, it should work with both. I might have introduced a regression in cider

@richiardiandrea currently on mobile but it might just work. What I assumed is that by just pressing enter, :dev would be used as default. But it’s given as an example.

Figwheel rocks!

Is it possible to remotely connect to the Figwheel REPL (either nrepl or socket repl)

?

I’d like to connect Cursive to the Figwheel REPL
