Hi! I am the author of a GraphQL schema builder for typescript (GiraphQL) and I recently released a plugin that makes it easy to build out GraphQL APIs backed by prisma, and does query introspection to avoid n+1 issues with nested queries. Today I just released an update the adds relay integration, letting you define nodes and connections with automatic n+1 handling in a completely type-safe way. Check it out and let me know what you think!
