IPython notebook viewer is an heroku application that given the url of a IPython notebook file (ending in ipynb) shows you a static html version.

If you have an heroku account, or have access to one, have a look at heroku-bootstrap.sh that does a quick setup of an heroku account and set some variables:

$ ./heroku-bootstrap.sh <an-app-name>

Push the repo on your new app

$ git push <an-app-name> master:master
...
...

The application will be available under yourappname.herokuapp.com

The app is based on Twitter Bootstrap so you will need some dependencies like node,uglify-js.

• everything in /static/ is served statically
• html files in /static/ are built from /template/ by doing $ make in the root dirrectory
• /template/layout.mustache contain headers and footers
• every *.mustache file in template/pages will create a corresponding html file in /static/
• any required python package should be availlable via pip, and should be added to requirement.txt. see pip freeze to know what to write in the file.
• local debug mode is activated by creating a .debug file in the root directory, .debug is excluded in .gitignoreand .slugignore

Sqlalchemy needs to connect to a database, you should export the environment variable DATABASE_URL. If you don't have any installed DB or just want to try out, you can use in memory sqlite :

$ export DATABASE_URL='sqlite:///:memory:'

heroku create [appname]
heroku git:remote -a [appname] -r [appname]
heroku addons:add memcachier:dev --app [appname]
heroku addons:add newrelic:standard --app [appname]

to deploy the new version :

git push nbviewer2 <local-branch>:master

You can eventually set the following github key to make authenticated requests to github. This will increase the maximum number of requests you can do to github /hour.

GITHUB_OAUTH_KEY:             xxxxxxxxxxxxxxxxxxxx
GITHUB_OAUTH_SECRET:          xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

you can use heroku config:set KEY1=VALUE1 to do so.
