GraphQL - A query language to empower your API consumers
summary
GraphQL sits as a thin query layer that returns exactly the fields a client requests in one round trip, cutting “chatty” REST calls; the demo uses Facebook’s JavaScript reference server with a live demo app that shows working GraphiQL IDE exploration, resolver functions calling back-end services, per-request batching via data loader, and push updates over WebSockets as subscriptions that actually fire. Client tooling options include Apollo client and Relay, and the recommended approach for large lists is cursor-based pagination.
