graphql-kotlin VS graphql-spqr

[dariuszkuc]

I haven't looked in depth at graphql-spqr but I believe the biggest difference is in the way the schemas are generated - graphql-spqr relies on explicit annotations and manual registration of the operations to build a schema whereas graphql-kotlin relies on Kotlin reflections to generate the schema directly from the code. While graphql-kotlin also ships with some annotations they are optional and only used to enhance the schema with additional information that cannot be directly derived from Kotlin reflections.

Take a look at our example project to see how it could be integrated with Spring Boot.

We are taking a "resolver first" approach and taking advantage of the reflection Kotlin has. You could potentially convert an existing Kotlin Spring Boot REST API code base into GraphQL without changing the logic or models with our library. I would advise against that though as REST models don't always translate to the best GraphQL schema.

I'm going to mark as closed/answered but please ask any other questions you might have as this will be searchable by others in the future!
