A re-frame application designed to ... well, that part is up to you.
Put this in your Emacs config file:
(setq cider-cljs-lein-repl
"(do (require 'figwheel-sidecar.repl-api)
(figwheel-sidecar.repl-api/start-figwheel!)
(figwheel-sidecar.repl-api/cljs-repl))")
Navigate to a clojurescript file and start a figwheel REPL with cider-jack-in-clojurescript or (C-c M-J)
lein clean
lein figwheel dev
Figwheel will automatically push cljs changes to the browser.
Wait a bit, then browse to http://localhost:3449.
lein clean
lein with-profile prod uberjar
That should compile the clojurescript code first, and then create the standalone jar.
When you run the jar you can set the port the ring server will use by setting the environment variable PORT. If it's not set, it will run on port 3000 by default.
To deploy to heroku, first create your app:
heroku create
Then deploy the application:
git push heroku master
To compile clojurescript to javascript:
lein clean
lein cljsbuild once min
