Writing Queryable API's with GraphQL
summary
Converts an existing REST movie API into a GraphQL API using Quarkus dev mode and MicroProfile GraphQL, replacing two endpoints with a single schema and supporting both a dynamic and typesafe client. Implements source fields for nested fetching (returns the top three actors — Tom Cruise, Val Kilmer, Miles Teller), map support as key/value lists, mutations that update ratings (example rating moves from 9.4 to 8.3 and later 7.7), subscriptions over websockets via Mutiny Multi, non‑blocking Uni responses, and Keycloak OpenID Connect security.
