GraphQL Servers
summary
A GraphQL server exposes a single endpoint that takes a query string and runs five concrete components: parser/lexer, type system, introspection, validation and a centralized execution engine that threads promises and exploits sibling parallelism. The demo overlays GraphQL on a REST API using a rest polyfill and a local Star Wars dataset so the GraphiQL UI autocompletes and returns 37 total Starships; the overlay works but has long‑term performance tradeoffs.
