GraphQL Resolvers
Implements efficient, maintainable GraphQL resolvers using industry-standard patterns for data fetching, batching, and security.
This skill provides specialized guidance for building robust GraphQL backends by enforcing best practices in resolver implementation. It covers the complete resolver lifecycle, including function signatures, field-level resolution, context-based dependency injection, and the critical DataLoader pattern for solving N+1 query performance issues. Whether you are architecting a new API or optimizing an existing one, this skill ensures your server handles asynchronous operations, authentication, and error reporting according to professional software development standards.
