This is a very simple sinatra app, built to be run on heroku.

It has only one endpoint: /locate , that returns a JSON with the location of the IP address of the requester (using MAXMIND’s free location database).

Running locally

git clone REPO
bundle install
bundle exec ruby geolocate.rb

Pushing to your own heroku instance

git clone REPO
cd REPO
heroku create
heroku addons:add newrelic:standard
heroku config:add RACK_ENV=production
git push heroku master
