Open a terminal and type lein repl to start a Clojure REPL
(interactive prompt).
In the REPL, type
(run)
(browser-repl)The call to (run) does two things, it starts the webserver at port
10555, and also the Figwheel server which takes care of live reloading
ClojureScript code and CSS. Give them some time to start.
Running (browser-repl) starts the Weasel REPL server, and drops you
into a ClojureScript REPL. Evaluating expressions here will only work
once you've loaded the page, so the browser can connect to Weasel.
When you see the line Successfully compiled "resources/public/app.js" in 21.36 seconds., you're ready to go. Browse to
http://localhost:8888 and enjoy.
Attention: It is not longer needed to run lein figwheel
separately. This is now taken care of behind the scenes
If all is well you now have a browser window saying 'Hello Chestnut',
and a REPL prompt that looks like cljs.user=>.
Open resources/public/css/style.css and change some styling of the
H1 element. Notice how it's updated instantly in the browser.
Open src/cljs/cerberus/core.cljs, and change dom/h1 to
dom/h2. As soon as you save the file, your browser is updated.
In the REPL, type
(ns cerberus.core)
(swap! app-state assoc :text "Interactivity FTW")
Notice again how the browser updates.
This assumes you have a
Heroku account, have installed the
Heroku toolbelt, and have done a
heroku login before.
git init
git add -A
git commit
heroku create
git push heroku master:master
heroku openHeroku uses Foreman to run your
app, which uses the Procfile in your repository to figure out which
server command to run. Heroku also compiles and runs your code with a
Leiningen "production" profile, instead of "dev". To locally simulate
what Heroku does you can do:
lein with-profile -dev,+production uberjar && foreman startNow your app is running at http://localhost:5000 in production mode.
