The Neo4j Cypher-DSL in its current form is a spin-off from Spring Data Neo4j 6+ (né Spring Data Neo4j⚡️RX), where it is used to generate all Cypher queries. We thank all contributors to all branches prior to 2020.0 for their effort in creating the previous versions.

The primary goal of this project is to have a type safe way of creating Cypher queries targeted at Neo4j 4.0+. Most of the constructs used here are modelled after openCypher, but we include several constructs specific to Neo4j.

The core module of the Neo4j Cypher-DSL has no required runtime dependencies.

This rebooted version of the Neo4j Cypher-DSL uses CalVer in the same way Spring does since early 2020 (see Updates to Spring Versions), starting at 2020.0.0.

For a gentle introduction and some getting started guides, please use our Manual.

Adding the necessary dependencies

<dependency>
	<groupId>org.neo4j</groupId>
	<artifactId>neo4j-cypher-dsl</artifactId>
	<version>2023.3.1</version>
</dependency>

dependencies {
    implementation 'org.neo4j:neo4j-cypher-dsl:2023.3.1'
}

A simple example

import static org.neo4j.cypherdsl.core.Cypher.*;

import org.neo4j.cypherdsl.core.Cypher;

class SimpleExample {

    public static void main(String... a) {

        var m = node("Movie").named("m");
        var statement = Cypher.match(m)
            .returning(m)
            .build();

        System.out.println(statement.getCypher());
        // Prints MATCH (m:`Movie`) RETURN m
    }
}
