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.
