Detailed documentation for specific topics: - Covers schema definition, resolvers, context setup, and error handling with TypeScript support - Supports standalone mode for prototyping and integrations with Express, Fastify, Koa, and serverless environments - Includes resolver patterns, authentication/authorization, plugins, DataLoader for N+1 prevention, and performance optimization techniques - Provides reference documentation for data sources, error handling, troubleshooting, and lifecycle hooks - Int - 32-bit integer - Float - Double-precision floating-point - String - UTF-8 string - Boolean - true/false - ID - Unique...
