GraphQL Java vs GraphQL.js

GraphQL Java has no write-up on Specifiction yet; its figures are above.

GraphQL.js is the official JavaScript implementation of the GraphQL specification. It provides a parser, validator, executor, type system and related utilities for building GraphQL servers, clients, tools and schema workflows in JavaScript or TypeScript. Developers define a type schema and serve queries against it; the graphql function checks syntax and semantics before execution and reports invalid queries. Documentation identifies v17 as the current stable release, with v16 available for projects requiring older Node.js versions. Getting-started instructions require Node.js 22 or newer and provide installation commands for npm, pnpm, yarn and bun. The library runs in Node servers and browsers, distributes CommonJS and ESModule files, and the project says webpack and rollup builds should work. It is MIT-licensed, free, distributed through npm and intended for self-hosted deployment. Latest and previous major versions receive stated support, but no Long-Term Support version is offered.
