## What it is
GraphQL SPQR is a Java library that dynamically generates a GraphQL schema from existing Java code, enabling code-first GraphQL API development with minimal setup. It is deeply configurable and extensible, and works well in legacy projects without changes to the existing code base.

## Use cases
- add a graphql api to an existing java project
- generate graphql schema from java classes
- rapidly prototype a graphql server in java
- avoid duplicating schema definitions in a statically typed language
- expose spring boot services over graphql
- build a graphql api without writing sdl by hand

## When to choose
- you have existing Java business logic and want a GraphQL API with minimal boilerplate
- you prefer code-first schema generation over maintaining SDL files
- you need a highly configurable and extensible GraphQL layer on the JVM
- you want to iterate quickly on API design during prototyping

## When to avoid
- your team mandates schema-first GraphQL development with hand-written SDL
- you are not on the JVM or not using Java/Kotlin
- you need a standalone GraphQL gateway or federation solution rather than an embedded library
