neo4j-graphql.js Quickstart

A GraphQL to Cypher query execution layer for Neo4j and JavaScript GraphQL implementations.

Installation and usage


npm install --save neo4j-graphql-js


Start with GraphQL type definitions:

const typeDefs = `
type Movie {
title: String
year: Int
imdbRating: Float
genres: [Genre] @relation(name: "IN_GENRE", direction: "OUT")
type Genre {
name: String
movies: [Movie] @relation(name: "IN_GENRE", direction: "IN")

Create an executable GraphQL schema with auto-generated resolvers for Query and Mutation types, ordering, pagination, and support for computed fields defined using the @cypher GraphQL schema directive:

import { makeAugmentedSchema } from 'neo4j-graphql-js';
const schema = makeAugmentedSchema({ typeDefs });

Create a neo4j-javascript-driver instance:

import neo4j from 'neo4j-driver';
const driver = neo4j.driver(
neo4j.auth.basic('neo4j', 'letmein')

Use your favorite JavaScript GraphQL server implementation to serve your GraphQL schema, injecting the Neo4j driver instance into the context so your data can be resolved in Neo4j:

import { ApolloServer } from 'apollo-server';
const server = new ApolloServer({ schema, context: { driver } });
server.listen(3003, '').then(({ url }) => {
console.log(`GraphQL API ready at ${url}`);

If you don't want auto-generated resolvers, you can also call neo4jgraphql() in your GraphQL resolver. Your GraphQL query will be translated to Cypher and the query passed to Neo4j.

import { neo4jgraphql } from "neo4j-graphql-js";
const resolvers = {
Query: {
Movie(object, params, ctx, resolveInfo) {
return neo4jgraphql(object, params, ctx, resolveInfo);


  • Send a single query to the database
  • No need to write queries for each resolver
  • Exposes the power of the Cypher query language through GraphQL


  • Translate basic GraphQL queries to Cypher
  • first and offset arguments for pagination
  • @cypher schema directive for exposing Cypher through GraphQL
  • Handle fragments
  • Ordering
  • Filtering
  • Handle interface types
  • Handle inline fragments
  • Native database temporal types (Date, DateTime, LocalDateTime)
  • Native Point database type
