Covers the essentials for building GraphQL APIs with Apollo Server or Python's Graphene, including schema design, resolvers, and DataLoader for handling N+1 query problems. You get practical examples for queries, mutations, error handling with proper codes, and input validation. The schema examples show a typical user/post relationship structure. Use this when you're migrating from REST and want clients to request exactly what they need, or when you need real-time subscriptions. The best practices section is solid on query complexity limits and not exposing database internals, though you'll still need to configure rate limiting and authentication separately.
