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
