Demo from my Clojure/conj 2014 talk.
Deployed to heroku: pumpkin.
It demonstrates how to connect Om and Sente to push new data to our client and how to create data vis components and make them interact with each other. Data visualised comes from GitHub stats of an open source project - no authorisation neccessary but there is an API limit of 60 resource requests per hour.
It's built on top of an awesome leiningen template chestnut - a real life saver!
Start a REPL (in a terminal:
lein repl, or from Emacs: open a
clj/cljs file in the project, then do
M-x cider-jack-in. Make sure
CIDER is up to date).
In the REPL do
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.
When you see the line
Successfully compiled "resources/public/pumpkin.js" in 15.509 seconds., you're ready to go. Browse to
http://localhost:10555 and enjoy.
Deploying to Heroku
git init git add -A git commit heroku create git push heroku master:master heroku open
Running with Foreman
Heroku 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 start
Now your app is running at http://localhost:5000 in production mode.
