Generating a Schema
You can use
graphql-kotlin-schema-generator to generate a schema from Kotlin code and expose it with any server library.
See the docs in Schema Generator Getting Started.
graphql-kotlin-federation, you can generate an Apollo Federation compliant schema.
See the docs in Apollo Federation.
Running a Server
graphql-kotlin-spring-server is a combination of the schema generator, fedeation, and server libraries. If you are looking to run a GraphQL server, this is the place to start.
See the docs in Spring Server Overview.
Creating a Client
graphql-kotlin-plugins can be used to generate a
graphql-kotlin-client from an existing schema that is easy to use and type-safe.
See the docs in Client Overview.
examples module is a collection of working code and examples on how to use all of the
See the example docs for more info.
