Setup my System environment need some advice.

[idhowardgj94]

hello, I'm a newbie in clojure & clojureScript,

just try to learn and have fun with this amazing language.

currently, I faced a problem,

I try to use rum + tailwindcss + postcss + shadow-cljs + lein to setup my entire frontend application.

And I use lein run to run clojure code, which will start postcss and shadow-cljs dev server as an agent.

(ns dev.main
  (:require [clojure.java.shell :as shell]
            [shadow.cljs.devtools.api :as api]
            [shadow.cljs.devtools.server :as server]))

(defn watch-css
  ;; build and watch css.
  []
  (future (apply shell/sh ["node_modules/.bin/postcss" "--watch" "src/resume/assets/main.css"
                           "-o" "public/main.css"
                           "--config" "src/config/postcss.config.js"]))
    (println "[INFO] watch css......"))

(watch-css)
(defn start-server!
  []
  (server/start!))

(defn start-watch!
  []
  (api/watch :app))

(defn stop-watch!
  []
  (server/stop!))

(defn -main
  []
  (println "running postcss command...")
  (watch-css)

  (println "Start shadow-cljs develop server...")
  (start-server!)
  (start-watch!)
  (.addShutdownHook (Runtime/getRuntime) (Thread. #(do
                                                     (println "stop server...")
                                                     (stop-watch!)
                                                     (println "bye.")))))

The problem is that, postcss won't recompile if my cljs file changed.

if I use --watch in (watch-css)'s shell command,

this shell was just instantly stop, and noting return, and no css build.

currently, I use lein alias + pdo workaround to solve this problem.

  :plugins [[lein-shell "0.5.0"]
            [lein-pdo "0.1.1"]]
 :aliases {"shadow-cljs-run" ["run" "-m" "shadow.cljs.devtools.cli"]
            "dev" ["run" "-m" "shadow.cljs.devtools.cli" "watch" "app"]
            "css" ["shell"
                   "node_modules/.bin/postcss" "src/resume/assets/main.css"
                   "-o" "public/main.css"
                   "-w"
                   "--config" "src/config/postcss.config.js"]}

and use command to start clojure system:

lein pdo css, run

and it worked. but I wonder is this a problem that mount can solve?

if it is, how can I achieve my goal?

thanks for help.
