GraphQL - APIs the New Way

on YouTube ↗54m

" summary

Wix proves GraphQL as a practical replacement for REST by wiring a Spring Boot Java stack with graphql-java + graphql-java-tools + graphql-spring-boot-starter to expose a cart and product microservice system (one SQL-backed cart service plus a product HTTP service). The demo shows a single client query as one HTTP POST per client query, addresses N+1 by N+1 fixed by batching product IDs into one product call, adds an depth and complexity instrumentation defense, supports mutations and subscriptions, and runs end to end — it works, but caching and operational complexity remain real costs.
