neo4jr-social

Neo4jr-Social is a self contained HTTP REST + JSON interface to the graph database Neo4j. Neo4jr-Social supports simple dynamic node creation, building relationships between nodes and also includes a few common social networking queries out of the box (i.e. linkedin degrees of seperation and facebook friend suggestion) with more to come. Think of Neo4jr-Social is to Neo4j like Solr is to Lucene.

Neo4jr-Social was built in JRuby but is language agnostic and is designed to run as a self-contained service or can be deployed under Jetty or Tomcat.

Getting Started

Prerequisites

  • Java

  • JRuby: jruby.org

  • sudo aptitude install jruby1.2 rake rubygems

Building

Once done, use rvm to install latest jruby and required gems

  • rvm install jruby

  • rvm use –default jruby

  • gem install jruby-openssl

  • gem install rake

  • gem install rspec

  • gem install test-client

  • gem install rack-test

  • gem install json-jruby -v 1.4.1

  • gem install jeweler

  • gem install warbler

  • gem install rcov

Building the code and documentation

  • rake -T # optional, lists possible tasks

  • rake gemspec

  • rake rcov –debug

  • rake rdoc

  • rake warify

  • rake build

Or short version (without documentation)

  • rake gemspec warify build

Installing

Install Ruby Gem: neo4jr-social

  • gem install neo4jr-social

Running Neo4jr-Social

After installing the above gems, an executable 'start-neo4jr-social' should be in your $PATH. This will start the service and the database and listen for HTTP requests on localhost at port 8988 by default:

start-neo4jr-social -p8988

You can also start the service and specify the directory of where the neo4j database is stored or where to create a new database. If you omit this setting a database will be created in your tmp directory and destroyed when you shutdown the server.

start-neo4jr-social -p8988 -dsome_relative_or_absolute_directory

Run start-neo4jr-social –help to see all options
