Spark Java + GraphQL + Kotlin

This is a GraphQL server written in Kotlin. The repo contains some data for characters in Star Wars. It has a schema for this data and defines queries for it. The server uses Spark to expose a POST endpoint "/graphql". Queries from the client side should be passed to this endpoint.

Server

/graphQL

• query: GraphQL query to parse.
• variables: any variables for the query.

Example Usage

1. Start the 'StarWarsServerApplication':

   ./gradlew run
   

2. Use curl to query the graphql end point.
