![]() ![]() We’ve used the movie poster URLs and set them as images for nodes. A React Neo4j visualization created using ReGraph, featuring the Neo4j movie databaseĪlmost every aspect of our React Neo4j visualization can be customized to suit your preferred style. With a bit of polishing, we get a nice graph of our Movie dataset. This is trivial due to the strong type system of GraphQL: each nested result has a _typename property and we can get unique _id properties as part of our query. ![]() We use a function called createItems here that maps the result from our GraphQL endpoint to the simple format expected by ReGraph. To configure the Apollo Server in the index.js file, use: const Here we’re using a Neo4j dataset featuring the FIFA Women’s World Cup 2019: NEO4J_URI=bolt://:7687Īpollo Server also comes with GraphQL Playground – its own graphical, interactive GraphQL IDE. env file defines the Neo4j connection details. Yarn add apollo-server neo4j-graphql-js dotenv Let’s configure Apollo to create GraphQL workflows that’ll enable us to query our Neo4j database. Try ReGraph for free Configure the server-side API Want to build your own React Neo4j visualization? It only takes a few steps to build a very simple ReGraph application With minimal effort, we already have our first ReGraph application with a single node in the center of the screen. Now we’ll create our first chart, with a few small alterations to App.js: import React from 'react' Let’s add ReGraph as a dependency: cp ~/Downloads/regraph-1.5.0.tgz. If you don’t have access already, just request a free ReGraph trial. Now we’ll download the latest version of ReGraph and add it to the new React application. npx create-react-app grandstack-regraph-app create-react-app from Facebook provides all the boilerplate we need. We’ll create a basic React application that we can adapt to use a GraphQL endpoint. Architecture diagram showing how ReGraph integrates with Neo4j using GRANDstack Create a ReGraph application The JSON response is sent to ReGraph where it updates the React props and the graph visualization. When our ReGraph application issues a GraphQL query, the GraphQL API sends a Cypher query to Neo4j via the Bolt protocol. Here’s the basic architecture we’re building. This takes away complexity, making it much easier to build applications. Such is the nature of web development today, “from scratch” actually means we’ll be leveraging some excellent open-source libraries. This simple starter project provides all the tools you need to build an application.īut for this blog post, we’ll build our front and back end “from scratch” to show how easy it is. One way to get started is to use the grand-stack-starter repository from Neo4j. Integrate your React component with Neo4j Modern developer tools for building full-stack applications have improved substantially, and Neo4j promote the best of them under their GRANDstack banner. GraphQL was a relatively new tool back then, but a lot has changed since. ![]() I also blogged about building a Neo4j graph and timeline visualization app that drives fraud investigations and an application to pull data efficiently from the GitHub API, using Neo4j and the other premium tools in GRANDstack such as the Facebook-backed query language, GraphQL. GRANDstack is Neo4j’s full development stack, combining their JavaScript library with Apollo Tools, React and Neo4j. We’ll also use datasets featuring movies and the FIFA Women’s World Cup to showcase some of the things you can achieve with your charts. It contains all the code from my talk at NODES 19, Neo4j’s online developer summit ( watch it on YouTube). In this blog post, I’ll show how quickly and easily you can use ReGraph, our graph visualization toolkit for React developers, and GRANDstack to build a React Neo4j visualization application. It’s by far the most popular graph database integration for organizations using our toolkits to create efficient, easily-maintained graph visualization applications. Many Cambridge Intelligence customers love building Neo4j graph visualizations. ![]()
