To prevent N+1 queries in a Golang GraphQL API, implement DataLoaders to batch and cache database requests. This pattern ensures that resolving nested list fields only triggers a single batched query per level instead of individual queries per item.

The best way to structure Go GraphQL resolvers is to keep them thin by delegating business logic to separate service layers. This approach maintains clean architecture and ensures that resolver files only handle schema mapping and data fetching orchestration.

To secure a GraphQL API in Go, implement query complexity limits and depth restrictions to block expensive queries. Additionally, configure proper error handling and disable introspection in production environments to prevent schema leakage.

Yes, gqlgen supports schema-first workflows for Go backend development by generating resolver boilerplate directly from your GraphQL schema definitions. This allows you to design your API contract upfront and map it to Go implementations afterward.

Implement pagination in a Golang GraphQL API by defining cursor-based or offset-based connections in your schema. Apply these patterns within your resolvers to limit data fetching and return structured edges with metadata for client navigation.
