This package allows you to connect and query Neo4j from Meteor.
# install neo4j
brew install neo4j
# add ccorcos:neo4j to your project
meteor add ccorcos:neo4j
# start neo4j
neo4j start
# start meteor
meteor
# stop neo4j
neo4j stop
You can access the Neo4j admin browser interface here.
m4j can start and stop Neo4j localized to your .meteor project.
curl -O https://raw.githubusercontent.com/ccorcos/meteor-neo4j/master/m4j
chmod +x m4j
# start within a meteor project
m4j start
# stop neo4j
m4j stop
m4j will edit the configuration files for Neo4j to do this so you need to
provide a NEO4J_PATH environment variable. Put this in your ~/.bashrc:
export NEO4J_PATH=/usr/local/Cellar/neo4j/2.1.7
Also, meteor reset will clear Neo4j as well, but you may want to make sure
to stop Neo4j before doing that.
You can create a Neo4j connection (url defaults to localhost:7474)
Neo4j = new Neo4jDb(optionalUrl)Neo4j will be autoconnected if given Meteor.settings.neo4j_url or process.env.NEO4J_URL.
You can query Neo4j using Cypher.
result = Neo4j.query "MATCH (a) RETURN a"When stringifying variables into Cypher queries, use Neo4j.stringify and Neo4j.regexify.
str = Neo4jDB.stringify
Neo4j.query "CREATE (p:PERSON #{str(user)}) RETURN p"
regex = Neo4jDB.regexify
Neo4j.query "CREATE (p:PERSON) WHERE p.name =~ #{regex(query)} RETURN p"
