What problem does it solve?

This Skill helps you implement GraphQL APIs in Go that are secure, performant, and production-safe by applying proven patterns for schema design, resolver structure, batching, authorization, and error handling.

Core Features & Use Cases

• Library-aware GraphQL server implementation: Choose and implement schema-first approaches with gqlgen or graphql-go, including guidance on when to avoid graphql-go’s code-first package.
• Resolver patterns that scale: Keep resolvers thin by delegating work to services, enforce nullability correctly, and structure mutations with payload envelopes for business errors.
• Production-grade safety and performance: Prevent N+1 queries with per-request DataLoaders, cap query complexity/depth, gate introspection in production, and ensure subscription goroutines respect context cancellation.
• Operational correctness: Implement subscriptions safely over WebSockets, add OpenTelemetry tracing, handle error sanitization via ErrorPresenter/ResolverError, and wire federation v2 in gqlgen.

Quick Start

Use the golang-graphql skill to implement a production-ready GraphQL API in Go with gqlgen or graphql-go, including per-request DataLoaders, complexity limits, and safe subscription handling.
