GraphGlueGraphQL servers, glued to your domain model

Annotation-based, code-first GraphQL on Kotlin, Spring Boot and Neo4j - with connections, filtering, ordering and authorization built in.

Relations, declared in Kotlin
Declare relationships as delegated properties. Many-sides automatically become GraphQL connections, and lazy loading fetches whole subtrees in a single query.
One GraphQL query, one Cypher query
Queries are translated straight into Neo4j Cypher instead of being resolved field by field, so the n+1 problem never appears in the first place.
Declarative authorization
Annotate nodes with the permissions they require, inherit permissions across relations, and extend the rules with Spring beans. Checks run in the database.
Filtering and ordering for free
Filter by properties and across relations, order by any comparable property, and add property-independent filters and orders of your own.
Built on tools you already use
Every GraphQL Kotlin and Spring Data Neo4j feature keeps working. GraphGlue adds to them rather than replacing them.
GraphiQL included
A GraphiQL instance with the explorer plugin is served out of the box, so the schema is explorable from the first run.
