manifold-sample-graphql-app

A sample GraphQL application using Manifold GraphQL and SparkJava.

Notable:

• Demonstrates Schema-first and single source of truth solely with GraphQL schema files. No code gen step!, no POJOs, no annotations.
• A GraphQL server with SparkJava is a natural fit with Manifold's GraphQL support as defined in MovieServer
• GraphQL client code is made simple as illustrated in the MovieClient class
• Rich development experience. With Manifold's IntelliJ IDEA plugin you can rapidly build queries and mutations with GraphQL. Quickly navigate between GraphQL schema files and usages in your code, refactor, find usages, code completion, incremental compilation, etc. All without the burden of a code generation step or maintaining POJOs -- your GraphQL schema files are your API!
