@Schlogen has done a great job to bring GraphQL support to GORM. A huge addition to the GORM family.
Both a Core Library:
The GORM GraphQL library provides functionality to generate a GraphQL schema based on your GORM entities, the core library also provides default implementations of "data fetchers" to query, update, and delete data through executions of the schema.
And a Grails Plugin:
A controller to receive and respond to GraphQL requests through HTTP, based on their guidelines.
Generates the schema at startup with spring bean configuration to make it easy to extend.
Includes a GraphiQL browser enabled by default in development. The browser is accessible at /graphql/browser.
Overrides the default data binder to use the data binding provided by Grails
Provides a trait to make integration testing of your GraphQL endpoints easier.
