Neo4j Example with GraphQL and Apollo

This is a simple setup for Next using Neo4j Database with GraphQL and Apollo. Neo4j's Movies dataset example is used to run the example.

Deploy your own

Once you have access to the environment variables you'll need, deploy the example using Vercel:

How to use

Execute create-next-app with npm, Yarn, or pnpm to bootstrap the example:

npx create-next-app --example with-apollo-neo4j-graphql with-apollo-neo4j-graphql-app

yarn create next-app --example with-apollo-neo4j-graphql with-apollo-neo4j-graphql-app

pnpm create next-app --example with-apollo-neo4j-graphql with-apollo-neo4j-graphql-app

Configuration

Step 1. Create a Neo4j database

First, you'll need a Neo4j database. Neo4j Desktop and Neo4j Online Sandbox are good and free-to-use options.

Step 2. Add the movie graph model to the database

This example uses a database containing Movies, you can add it like so:

:play movie-graph

Also included is a Cypher movie sample query if needed.

Step 3. Set up environment variables

Next, copy the .env.local.example file in this directory to .env.local (which will be ignored by Git):

cp .env.local.example .env.local

Then set each variable on .env.local to match your database URI and credentials.

Deploy on Vercel

You can deploy this app to the cloud with Vercel (Documentation).

Deploy Your Local Project

To deploy your local project to Vercel, push it to GitHub/GitLab/Bitbucket and import to Vercel.

Important: When you import your project on Vercel, make sure to click on Environment Variables and set them to match your .env.local file.

Deploy from Our Template

Alternatively, you can deploy using our template by clicking on the Deploy button below.
