Install Dependencies

The Mongo procedures have dependencies on a client library that is not included in the APOC Library.

This dependency is included in apoc-mongodb-dependencies-4.1.0.11.jar, which can be downloaded from the releases page. Once that file is downloaded, it should be placed in the plugins directory and the Neo4j Server restarted.

Usage Examples

The examples in this section are based on a Mongo DB instance with a pre-populate twitter dataset. You can find instructions for setting this up at github.com/neo4j-examples/mongo-example.
