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
• R2DBC Query By Example (QBE)
• Custom Pagination
• 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 8083. You can send your POST request against http://localhost:8083/nintendo/project/graphql.

Playing with this API

Checkout the attached Postman Collection for more examples. Below is one for querying all project data based off criteria passed

query lookUpByCriteria($teamId: NintendoTeamId!, $franchiseId: NintendoGuid!, $status: ProjectStatus!){
    projectsByCriteria(teamId: $teamId, franchiseId: $franchiseId, status: $status) {
        projectId
        franchiseId
        projectName
        teamId
        status
        lastModified
    }
}

{
    "teamId" : "nintendo01",
    "franchiseId" : "n1nt3nd0-11a8-4d5b-beda-franch1s3001",
    "status": "COMPLETED"
}
