Neo4j.rb, a Ruby on Rails and Rack framework replacement for Neo4j, has been released after a year of contributions. The new version, version 3.0, offers improved deployment options, support for Neo4j REST Server using Ruby MRI, and a rewritten Cypher query DSL called QueryProxy that provides ActiveRecord-like syntax and increased power. This allows developers to easily create complex queries without needing advanced knowledge of the Cypher language. Additionally, Neo4j.rb introduces ActiveRel, relationship wrapper models, and Neo4j-flavored Enumerable methods, making it more friendly for Rails developers and committed to maintaining its features with a growing community.
