Prototype of an openfaas function in Node.js that communicate with a neo4j DB

• Start a neo4j instance and use the default movie database

• Create some review relationships:

MATCH (p:Person)
WITH p
MATCH (m:Movie)
WITH p, m
WHERE NOT (p)-[:WROTE|:DIRECTED|:ACTED_IN|:PRODUCED]->(m)
CREATE (p)-[:REVIEWED]->(m)

• Create some follow relationships:

MATCH (p:Person)
WITH p
MATCH (p2:Person)
WHERE NOT p.name = p2.name AND NOT (p)-[]-(p2)
LIMIT 100
CREATE (p)-[:FOLLOWS]->(p2)

• Edit the neo4j-prototype.yml according to your environment

• Edit the neo4j driver variable in neo4j-prototype/handler.js according to your neo4j instance

• Deploy the function: faas-cli up -f neo4j-prototype.yml

• Test the function: cat test.json | faas-cli invoke -f neo4j-prototype.yml neo4j-prototype
