Getting Started
GraphQL Kotlin is a collection of libraries, built on top of graphql-java, that simplify running GraphQL clients and servers in Kotlin.
Installation
Using a JVM dependency manager, link any graphql-kotlin-* library to your project.
- Gradle Kotlin
- Maven
implementation("com.expediagroup", "graphql-kotlin-spring-server", latestVersion)
<dependency>
<groupId>com.expediagroup</groupId>
<artifactId>graphql-kotlin-spring-server</artifactId>
<version>${latestVersion}</version>
</dependency>
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.
Apollo Federation
Using graphql-kotlin-federation, you can generate an Apollo Federation compliant schema.
See the docs in Apollo Federation.
Running a Server
graphql-kotlin-server is a combination of the schema generator, federation, and server libraries. If you are looking to run a GraphQL server, this is the place to start.
See the docs in GraphQL Kotlin Server.
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
The examples module is a collection of working code and examples on how to use all of the graphql-kotlin modules.
See the example docs for more info.
