Neo4j: Graphs for Everyone

Neo4j is the world’s leading Graph Database. It is a high performance graph store with all the features expected of a mature and robust database, like a friendly query language and ACID transactions. The programmer works with a flexible network structure of nodes and relationships rather than static tables — yet enjoys all the benefits of enterprise-quality database. For many applications, Neo4j offers orders of magnitude performance benefits compared to relational DBs.

Learn more on the Neo4j website.

Using Neo4j

Neo4j is available both as a standalone server, or an embeddable component. You can download or try online.

Building Neo4j

Neo4j is built using Apache Maven version 3.0.x and a recent version of Java 7.

The Neo4j Browser module is built using Node.js. For skipping that part of the build, see below.

  • A plain mvn clean install will only build the individual jar files.

  • Test execution is, of course, part of the build.

  • To add execution of integration tests, use: mvn clean install -DrunITs

  • In case you just want the jars, without compiling the tests, this is for you: mvn clean install -DminimalBuild

  • To skip building the browser module, use -DskipBrowser (note that you might not be able to build the server without it.)

  • To build everything, including running all tests, producing documentation and assembling product packages, use mvn clean install -DfullBuild

  • To build the documentation see the Neo4j manual

  • When building on Windows, use -Dlicensing.skip to avoid problems related to line endings.

  • The license header check can be skipped by appending the following to the command line: -Dlicense.skip=true
