What GraphQL.js is
GraphQL.js is the official JavaScript implementation of the GraphQL specification, provided as a free, MIT-licensed library for self-hosted projects. It is intended for building GraphQL servers, clients, tools, and schema workflows in JavaScript and TypeScript. Its components include a parser, validator, executor, type system, and utilities. Developers can define a type schema and serve queries against it; the `graphql` function checks query syntax and meaning before execution and reports invalid queries. The documentation identifies v17 as the current stable release and retains v16 for projects that need older Node.js versions. Its getting-started guide requires Node.js 22 or newer. Installation instructions cover npm, pnpm, yarn, and bun. The library can run in a Node server or browser, and is distributed in CommonJS and ESModule formats; the project says webpack and rollup builds should work. It fully supports the latest major version and provides bug and security fixes for the previous major version. Older versions are unsupported, and there is no Long-Term Support release.
