Using Neo4j from Erlang and Elixir

Goals
If you are an Erlang, or today an Elixir developer, this guide provides an overview of options for connecting to Neo4j. While this guide is not comprehensive it will introduce the different drivers and link to the relevant resources.
Prerequisites
You should be familiar with graph database concepts and the property graph model. You should have installed Neo4j and made yourself familiar with our Cypher Query language.
Intermediate

Neo4j for Erlang/Elixir Developers

erlang

elixir

Members of the Erlang and Elixir community have invested a lot of time and love to develop these drivers, so please if you use them, provide feedback to the authors.

The Example Project

The Neo4j example project is a small, one page webapp for the movies database built into the Neo4j tutorial. The front-end page is the same for all drivers: movie search, movie details, and a graph visualization of actors and movies. Each backend implementation shows you how to connect to Neo4j from each of the different languages and drivers.

You can learn more about our small, consistent example project across many different language drivers here. You will find the implementations for all drivers as individual GitHub repositories, which you can clone and deploy directly.

Neo4j Community Drivers

The drivers below have been thankfully contributed by the Neo4j community. Many of these are fully featured and well maintained. But we don’t take any responsibility for their fitness for use with the most recent versions of Neo4j.

Elixir Bolt.Sips Driver

Neo4j driver for Elixir wrapped around the Bolt protocol.

Features:

  • It is using: Bolt. Neo4j’s newest network protocol, designed for high-performance
  • Supports transactions, simple and complex Cypher queries with or w/o parameters
  • Connection pool implementation using: “A hunky Erlang worker pool factory”, aka: Poolboy 🙂
  • Supports Neo4j 3.0.x

Neo4j.Sips

A simple Elixir wrapper around the Neo4j graph database REST API. It is aiming to help Elixir developers to play with Neo4j, and to eventually become the main support for a future Ecto adapter.
