Chimp Gql Federation Example

Please read docs at https://chimpjs.com to learn about this Repository.

Structure

This repository consists of 6 independent packages:

• graphql-gateway TypeScript thin layer powered by Apollo Gateway
• graphql-todo-items TypeScript Federated Graph responsible for Todo Items (and extending Lists)
• graphql-todo-lists TypeScript Federated Graph responsible for Todo Lists
• microservice-todo-items Kotlin Spring Microservice responsible for operations related to Todo Items
• microservice-todo-lists Kotlin Spring Microservice responsible for operations related to Todo Lists
• web React Frontend - a playground frontend that works with this architecture even though it was written over multiple years for a monolithic GraphQL / MongoDB server - but since the GraphQL Schema matches our Federated, it works just fine.

Setup
