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

    neo4j-graphql.js is facilitated by Neo4j Labs.

    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 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 { v1 as 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);

    What is neo4j-graphql.js

    A package to make it easier to use GraphQL and Neo4j together. neo4j-graphql.js translates GraphQL queries to a single Cypher query, eliminating the need to write queries in GraphQL resolvers and for batching queries. It also exposes the Cypher query language through GraphQL via the @cypher schema directive.


    • Translate GraphQL queries to Cypher to simplify the process of writing GraphQL resolvers
    • Allow for custom logic by overriding of any resolver function
    • Work with graphql-tools, graphql-js, and apollo-server
    • Support GraphQL servers that need to resolve data from multiple data services/databases
    • Expose the power of Cypher through GraphQL via the @cypher directive


    • 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

    Debugging and Tuning

    You can log out the generated cypher statements with an environment variable:

    DEBUG=neo4j-graphql-js node yourcode.js

    This helps to debug and optimize your database statements. E.g. visit your Neo4J browser console at http://localhost:7474/browser/ and paste the following:

    :params :params { offset: 0, first: 12, filter: {}, cypherParams: { currentUserId: '42' } }

    and now profile the generated query:

    EXPLAIN MATCH (`post`:`Post`) WITH `post` ORDER BY post.createdAt DESC RETURN `post` { .id , .title } AS `post`

    You can learn more by typing:

    :help EXPLAIN
    :help params
