Fun with GraphQL

This is just a simple Spring GraphQL API that is part of a schema stitching exercise over on Fun with GraphQL Schema Stitching.

Next Steps

• Mutations will be added next and we'll see how that comes into play with Fun with GraphQL Schema Stitching.

Interesting things to learn from this Project

• Defining Schema Types in schema.graphql
• Custom GraphQL Scalar Types for validation
• QueryResolvers and how they work with our GraphQL Queries
• Async Threads for executing GraphQL Queries
• Pagination with Relay Connection
• Integration Test with Spring GraphQL
• Working with a local H2 Database

Running this application.

./gradlew clean build ./gradlew bootRun

Application will be exposed on port 8082. You can send your POST request against http://localhost:8082/nintendo/contact/graphql.

Playing with this API

Checkout the attached Postman Collection for more examples. Below is one for querying all contact details

query contactInformation($nintendoId: NintendoId!){
