Neo4j: Can I Use <X>?

This is an INTERNAL library designed to be used within official Neo4j products. No guarantees are made regarding its API stability and support.

Simple Neo4j Feature Detection Library for Neo4j clients.

Prerequisites

Build

• JDK 11
• Recent Maven (3+)

Run

• JRE 11+

Quick Start

Add org.neo4j:caniuse-core to your project.

import org.neo4j.caniuse.CanIUse.canIUse
import org.neo4j.caniuse.Cypher
import org.neo4j.caniuse.Neo4j
import org.neo4j.caniuse.Neo4jEdition.ENTERPRISE
import org.neo4j.caniuse.Neo4jDeploymentType.SELF_MANAGED
import org.neo4j.caniuse.Neo4jVersion

fun main(args: Array<String>) {
    val neo4j = Neo4j(Neo4jVersion(5, 26), ENTERPRISE, SELF_MANAGED)
    if (canIUse(Cypher.concurrentCallInTransactions()).withNeo4j(neo4j)) {
        // run concurrent CALL IN TRANSACTIONS \o/
    }
}

You can find other feature detections in Cypher, as well as Dbms and Schema.

Neo4j detection

org.neo4j:caniuse-core only allows static definitions of your target Neo4j server's characteristics.

You can automatically retrieve these pieces of information by adding org.neo4j:caniuse-neo4j-detection alongside caniuse-core to your project.

The previous sample then becomes:

import org.neo4j.caniuse.CanIUse.canIUse
import org.neo4j.caniuse.Cypher
import org.neo4j.caniuse.Neo4jDetector
import org.neo4j.driver.AuthTokens
import org.neo4j.driver.GraphDatabase

fun main(args: Array<String>) {
    GraphDatabase.driver("neo4j://localhost", AuthTokens.basic("neo4j", "letmein!")).use { driver ->
        {
            val neo4j = Neo4jDetector.detect(driver)
            if (canIUse(Cypher.concurrentCallInTransactions()).withNeo4j(neo4j)) {
                // run concurrent CALL IN TRANSACTIONS \o/
            }
        }
    }
}
