GraphQL

Patterns for schema design, resolver implementation, N+1 prevention, and client-side queries. Applies to Apollo Server, Pothos, graphql-yoga, and Apollo Client.

When to Use

• Designing a GraphQL schema
• Implementing resolvers on the server
• Writing queries, mutations, or fragments on the client
• Diagnosing N+1 query problems or over-fetching

Don't use for:

• REST API design (use express or hono)
• tRPC (type-safe RPC, different paradigm)
• Database query optimization (use relevant ORM skill)
