Development

Open a terminal and type `lein repl` to start a Clojure REPL (interactive prompt).

In the REPL, type

(go)
(cljs-repl)

The call to (go) starts the Figwheel server at port 3449, which takes care of live reloading ClojureScript code and CSS, and the app server at port 10555 which forwards requests to the http-handler you define.

Running (cljs-repl) starts the Figwheel ClojureScript REPL. Evaluating expressions here will only work once you’ve loaded the page, so the browser can connect to Figwheel.

When you see the line Successfully compiled “resources/public/app.js” in 21.36 seconds., you’re ready to go. Browse to `http://localhost:10555` and enjoy.

Attention: It is not needed to run ‘lein figwheel’ separately. Instead ‘(go)’ launches Figwheel directly from the REPL**

Testing

To run the Clojure tests, use

lein test

To run the Clojurescript you use [doo](https://github.com/bensu/doo). This can run your tests against a variety of JavaScript implementations, but in the browser and “headless”. For example, to test with PhantomJS, use

lein doo phantom

Deploying to Heroku

This assumes you have a [Heroku account](https://signup.heroku.com/dc), have installed the [Heroku toolbelt](https://toolbelt.heroku.com/), and have done a `heroku login` before.

git init
git add -A
git commit
heroku create
git push heroku master:master
heroku open

Result

Running with Foreman

Heroku uses [Foreman](http://ddollar.github.io/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 start

Now your app is running at [http://localhost:5000](http://localhost:5000) in production mode.
