GeoIPJSON - GeoIP information as JSON via a rack app

A very simple rack app to provide Geo-location Information as JSON.

By default it returns the country code of the current client.

Alternatively, an ?ip=1.2.3.4 parameter can be supplied.

We are using this as a datasource for an AJAX call.

Install

Rails

In Gemfile

gem 'geo-ip-json'

In routes.rb

<AppName>::Application.routes.draw do
  match "/geoip.json", :to => GeoIPJson::App.new
end

Download the GeoIP database file from MaxMind (http://www.maxmind.com/)

• http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz

Put it in the root of your Rails app (configurable location is coming)

Testing

Run rake test to run the tests. A Guardfile is present to use with Guard.

Thanks!
