A Heroku web app using Compojure.
This generated project has a few basics set up beyond the bare Compojure defaults:
- Cookie-backed session store
- Stack traces when in development
- Environment-based config via enviorn
- HTTP-based REPL debugging via drawbridge
To start a local web server for development you can either eval the
commented out forms at the bottom of web.clj from your editor or
launch from the command line:
$ lein run -m danlentz.web
Initialize a git repository for your project.
$ git init
$ git add .
$ git commit -m "Initial commit."
You'll need the heroku toolbelt installed to manage the heroku side of your app. Once it's installed, get the app created:
$ heroku apps:create danlentz
Creating danlentz... done, stack is cedar

Git remote heroku added
You can deploy the skeleton project immediately:
$ git push heroku master

* [new branch] master -> master
It's live! Hit it with curl:
$ curl http://danlentz.herokuap.com
["Hello" :from Heroku]
The cookie-backed session store needs a session secret configured for encryption:
$ heroku config:add SESSION_SECRET=$RANDOM_16_CHARS
The devcenter article
has a detailed explanation, but using the repl task from Leiningen
2.x lets you connect a REPL to a remote process over HTTP. The first
step is setting up credentials:
$ heroku config:add REPL_USER=[...] REPL_PASSWORD=[...]
Then you can launch the REPL:
$ lein repl :connect http://$REPL_USER:[email protected]/repl
Everything you enter will be evaluated remotely in the running dyno, which can be very useful for debugging or inspecting live data.
