GraphQL gives clients exactly the data they need - no more, no
Why this skill is useful
Adds specific GraphQL schema design patterns and DataLoader usage that the AI wouldn't reliably generate on its own.
What it needs
Requires @apollo/server, dataloader, graphql-codegen installed locally. About 11k tokens when loaded. Last updated 2026-08-07. 405 stars on the source repository.
What this skill does
GraphQL GraphQL gives clients exactly the data they need - no more, no less. One endpoint, typed schema, introspection. But the flexibility that makes it powerful also makes it dangerous. Without proper controls, clients can craft queries that bring down your server. This skill covers schema design, resolvers, DataLoader for N+1 prevention, federation for microservices, and client integration with Apollo/urql. Key insight: GraphQL is a contract. The schema is the API documentation. Design it carefully. 2025 lesson: GraphQL isn't always the answer. For simple CRUD, REST is simpler. For high-performance public APIs, REST with caching wins. Use GraphQL when you have complex data relationships and diverse client needs. Principles Schema-first design - the schema is the contract Prevent N+1 queries with DataLoader Limit query depth and complexity Use fragments for reusable selections Mutations should be specific, not generic update operations Errors are data - use union types for expected failures Nullability is meaningful - design it intentionally Capabilities graphql-schema-design graphql-resolvers graphql-federation graphql-subscriptions graphql-dataloader graphql-codegen apollo-server apollo-client urql Scope database-queries -> postgres-wizard authentication -> authentication-oauth rest-api-design -> backend websocket-infrastructure -> backend Tooling Server @apollo/server - When: Apollo Server v4 Note: Most popular GraphQL server graphql-yoga - When: Lightweight alternative Note: Good for serverless mercurius - When: Fastify integration Note: Fast, uses JIT Client @apollo/client - When: Full-featured client Note: Caching, state management urql - When: Lightweight alternative Note: Smaller, simpler graphql-request - When: Simple requests Note: Minimal, no caching Tools graphql-codegen - When: Type generation Note: Essential for TypeScript dataloader - When: N+1 prevention Note: Batches and caches Patterns Schema Design Type-safe schema with proper nullability When t …
