The Neo4j-core Ruby driver

This example demonstrates how to use neo4j-core to execute cypher queries.

Basically, this is a simple Sinatra application, providing a number of endpoints /graph, /search and /movie. These execute hard-coded Cypher queries against the Neo4j Server backend, and parse the results to provide JSON responses to the frontend JavaScript code.

How to Install

bundle install

How to run

In your Neo4j web console UI you should type :play movies to load the data into your database.

Then to start up the web server:

# with rackup
NEO4J_URL=http://neo4j:neo5j@localhost:7474 bundle exec rackup config.ru

If your neo4j server is not running on http://localhost:7474 then you can specify an alternate location with an environment variable named NEO4J_URL. You can use either http or bolt like so:

NEO4J_URL=http://neo4j:password@localhost:7474
NEO4J_URL=bolt://neo4j:password@localhost:7687

If your neo4j server is not running on localhost:7474 then you can specify an alternate location with an environment variable named NEO4J_URL.
