## What it is
GraphQL Java is the standard JVM implementation of the GraphQL specification, providing schema parsing, schema generation, and query execution. It serves as the foundation for Java GraphQL servers including Spring for GraphQL and Netflix DGS.

## Use cases
- build a graphql server in java
- parse and execute graphql queries on the jvm
- create a graphql api with spring boot
- generate an executable schema from graphql sdl
- implement custom data fetchers for a graphql api
- serve graphql instead of rest from a java backend

## When to choose
- you need a production-grade GraphQL engine on the JVM
- you are building a GraphQL service with Spring Boot or another Java framework
- you want the foundation used by Spring GraphQL and Netflix DGS

## When to avoid
- you need a full batteries-included HTTP GraphQL server out of the box (it is an engine, not a server)
- your stack is not on the JVM
- you only need a GraphQL client rather than a server implementation

## Facets
- artifact type: library
- maturity: stable
- function: graphql, api-framework, parser, http-server
- domain: apis, web-development, backend, developer-tools
- platform: jvm, serverless
- tags: graphql-server, schema-first, spring-graphql, federation, data-fetchers, web-server
