How does this skill handle the GraphQL N+1 problem?

It utilizes the DataLoader pattern to automatically batch and cache multiple individual data requests into a single, efficient database query.

Does it support custom error codes?

Yes, it implements best practices for throwing GraphQLError with extensions for specific error codes like UNAUTHENTICATED or BAD_USER_INPUT.

What arguments are used in the resolver functions?

The skill follows the standard GraphQL signature: parent (root), args (inputs), context (shared state), and info (query metadata).

Can this skill help with authentication in GraphQL?

Yes, it provides patterns for extracting authentication tokens, managing user state in the context object, and implementing reusable auth middleware.

API開発

Implements efficient, secure, and performant GraphQL resolvers using industry-standard patterns like DataLoader and context-based authentication.

概要

This skill provides Claude with specialized knowledge for architecting GraphQL APIs by implementing advanced resolver patterns. It covers the full lifecycle of a GraphQL request, from extracting data from the context object and managing execution chains to solving the N+1 query problem via DataLoader. It also includes robust strategies for async error handling, resource-based authorization, and field-level resolution, ensuring your API is both scalable and maintainable within Node.js and TypeScript environments.
