Example(s) that show how to use Federation JVM

[Dariusz Kuc]

Create example apps that show how to use Federation JVM with popular libraries/frameworks.

Examples:

• spring-graphql - official Spring project
• dgs-framework - The DGS Framework (Domain Graph Service) is a GraphQL server framework for Spring Boot, developed by Netflix.
• graphql-java-kickstart

Awesome!

I had previously raised the topic about the relationship between:

• spring-example within this repo (with two profiles)
• external samples (ie: dgs-federation-example or graphql-java-kickstart-federation-example)
• apollo-federation-subgraph-compatibility implementations (dgs, kickstart

Wondering if there is an opportunity to simplify and/or reference in the updated documentation

[Dariusz Kuc]

Good callouts. Existing spring-example in this repo is outdated and confusingly provides 2 examples (loaded based on the spring profiles).

I'm thinking we should:

• drop existing spring-example
• create new example based on spring-graphql
• link to the DGS and graphql-java-kickstart example projects that you listed above

[Dariusz Kuc]

Following the linked DGS and GraphQL Java Kickstart examples, I created separate https://github.com/apollographql/federation-jvm-spring-example repository as well. We will be dropping example subprojects from this repository.

Unfortunately, none of the examples showcase features like @requires directive processing.

👋 good callout! I've opened some issues in the https://github.com/apollographql/federation-jvm-spring-example repo to track adding additional use cases.
