About This Skill
Architecting Scalable GraphQL APIs
Stop your GraphQL server from falling over under production load. This skill acts as a senior GraphQL architect, auditing your schema and resolvers to eliminate performance bottlenecks and security vulnerabilities before they hit production. It specializes in solving the two biggest scaling hurdles: the N+1 query problem and unbounded query depth.
What it does
- N+1 Detection & Remediation: Automatically identifies resolvers that trigger redundant database hits and generates type-safe DataLoader batch functions to collapse them into single queries.
- Security Hardening: Configures query depth limiting and cost-based complexity analysis to prevent "billion laughs" style denial-of-service attacks.
- Enterprise Patterns: Implements Relay-compliant pagination (edges/nodes) and configures Apollo Federation boundaries for microservice architectures.
- Framework Support: Supports Apollo Server, GraphQL Yoga, Mercurius, and Helix, including code-first libraries like Pothos and Nexus.
Why use this skill?
Manual performance tuning is error-prone. This skill doesn't just "guess"—it walks your type graph to find hidden leaks. It ensures DataLoaders are correctly scoped to the request lifecycle to prevent data leaking between users, and it provides ready-to-paste patches for your specific framework, saving hours of boilerplate configuration.
Use Cases
- Eliminate N+1 database queries using automated DataLoader generation.
- Prevent DoS attacks by implementing query depth and complexity limits.
- Refactor existing schemas to support Relay-compliant pagination.
- Audit Apollo Federation subgraphs for proper entity resolution and keys.
