GraphQL - APIs the New Way
summary
Shows a working Java setup that front-ends can use to avoid over‑ and under‑fetching: a Spring Boot GraphQL layer sits above two microservices (cart + product) backed by SQL, using GraphiQL for queries and Charles to prove the network effect. Implements batching to reduce three HTTP calls to one, adds a per‑field limit and enforces depth and complexity limits, and demonstrates mutations and subscriptions; the live demo mostly works and the approach cuts round‑trips while requiring careful schema/code design.
