Hands-On With SwiftUI, GraphQL, & Neo4j AuraDB
WorkshopFree
Bring the power of graphs to iOS mobile app development in this hands-on workshop. We will explore how to use the Neo4j GraphQL Library to build GraphQL APIs backed by Neo4j AuraDB and how to integrate GraphQL into an iOS app using SwiftUI and the Apollo iOS GraphQL library as we build a news reader mobile app.
Table of contents:- Intro to Neo4j AuraDB- Building GraphQL APIs with the Neo4j GraphQL Library- Intro to SwiftUI- SwiftUI + GraphQL
PrerequisitesTo follow along during the workshop attendees will need a Mac laptop with a recent version of Xcode installed. Some familiarity with Swift and iOS app development will be helpful, although not required.

WorkshopFree
Learn how to use the Neo4j GraphQL library to build Node.js GraphQL APIs backed by the Neo4j graph database. This course covers building GraphQL APIs using the Neo4j GraphQL Library and the Neo4j AuraDB cloud-native database to build an e-comerce GraphQL API backed by a native graph database in the cloud.
Table of contents:- Introduction To GraphQL & Neo4j- The Neo4j GraphQL Library: modeling a graph with GraphQL type definitions; creating and querying a GraphQL API using the Neo4j GraphQL Library- Adding Custom Logic With Cypher And Custom Resolvers: using the @cypher GraphQL schema directive; adding custom resolver functions with the Neo4j GraphQL Library- Authorization With The Neo4j GraphQL Library: working with JSON Web Tokens (JWTs) to authenticate your API users; using the @auth GraphQL schema directive to attach authorization rules to your GraphQL API
Prerequisites:No local setup is required for the workshop. We will make use of Codesandbox (a browser-based tool for editing and running code in the browser) and Neo4j AuraDB, a free managed database service. Some familiarity with GraphQL and JavaScript is helpful, however not strictly required. No experience with Neo4j is necessary.

Putting the Graph In GraphQL With The Neo4j GraphQL Library
GraphQL exposes application data as a graph which can introduce challenges if your backend isn't graph-ready (think slow JOINs as a result of nested GraphQL queries and the dreaded n+1 query problem). The Neo4j GraphQL library enables developers to build GraphQL APIs backed a native graph database using only GraphQL type definitions. In this talk we'll see how to build a GraphQL API without writing any resolvers, add custom logic, and deploy to the cloud.

Full Stack GraphQL In The Cloud With Neo4j Aura, Next.js, & Vercel
WorkshopFree
In this workshop we will build and deploy a full stack GraphQL application using Next.js, Neo4j, and Vercel. Using a knowledge graph of news articles we will first build a GraphQL API using Next.js API routes and the Neo4j GraphQL Library. Next, we focus on the front-end, exploring how to use GraphQL for data fetching with a Next.js application. Lastly, we explore how to add personalization and content recommendation in our GraphQL API to serve relevant articles to our users, then deploy our application to the cloud using Vercel and Neo4j Aura.

Table of contents:
- Next.js overview and getting started with Next.js
- API Routes with Next.js & building a GraphQL API
- Using the Neo4j GraphQL Library
- Working with Apollo Client and GraphQL data fetching in Next.js
- Deploying with Vercel and Neo4j Aura

Building GraphQL APIs With The Neo4j GraphQL Library
WorkshopFree
This workshop will explore how to build GraphQL APIs backed Neo4j, a native graph database. The Neo4j GraphQL Library allows developers to quickly design and implement fully functional GraphQL APIs without writing any resolvers. This workshop will show how to use the Neo4j GraphQL Library to build a Node.js GraphQL API, including adding custom logic and authorization rules.

Table of contents:
- Overview of GraphQL and building GraphQL APIs
- Building Node.js GraphQL APIs backed a native graph database using the Neo4j GraphQL Library
- Adding custom logic to our GraphQL API using the @cypher schema directive and custom resolvers
- Adding authentication and authorization rules to our GraphQL API
