GraphQL Skill

Summary

GraphQL is a query language and runtime for APIs that enables clients to request exactly the data they need. It provides a strongly-typed schema, single endpoint architecture, and eliminates over-fetching/under-fetching problems common in REST APIs.

When to Use

• Building flexible APIs for multiple client types (web, mobile, IoT)
• Complex data requirements with nested relationships
• Mobile-first applications needing bandwidth efficiency
• Reducing API versioning complexity
• Real-time data with subscriptions
• Microservices aggregation and federation
• Developer experience with strong typing and introspection
