neo4j-marshaller 0.0.1

Simplified Neo4J Cypher Query execution

neo4j_marshaller

neo4j_marshaller is a Python library that takes a Cypher Query, executes it, and returns the resultset as a JSON object. The idea is to

• avoid the boiler-plate code that has to "interpret" the returned BoltResultSet in-order to use the results
• easily supply named parameters in the Cypher Query
• get_one(): pick one row from returned BoltResultSet and return it as an object
• get_all(): treat the BoltResultSet and return it as an array

Here is the GitHub repo:

• https://github.com/arunsundaram50/neo4j-marshaller

Here is the pip command to install it:

pip install neo4j-marshaller

Here’s a simple example of how you might use neo4j_marshaller:

from neo4j_marshaller import Neo4JMarshallerResource
import json, sys, os

if __name__ == "__main__":

  email_address = os.environ['EMAIL_ADDRESS']
  cypher_query = """
      MATCH (user:ExplUser {name: $username})
      RETURN user
    """

  with Neo4JMarshallerResource() as nmr:
    userJson = nmr.get_one(cypher_query, username=email_address)
    json.dump(userJson, indent=2, fp=sys.stdout)
