GraphQL-IO is an opinionated MIT-licensed GraphQL -based network communication framework for JavaScript. The client-side runs under either Node.js or in the Browser. The server-side runs under Node.js.
While GraphQL is just a formal language specification and GraphQL.js is a reference implementation of a corresponding execution engine, GraphQL-IO is an entire all-in-one GraphQL-based network communication solution for both client and server.
It integrates the necessary third-party libraries, provides a convenient and flexible API and especially supports real-time updates of GraphQL queries (aka GraphQL subscriptions) over a high-performance, framed, and optionally compressed, WebSocket channel.
