GraphQL-IO

GraphQL Network Communication Framework

ATTENTION: This is just a meta-package for GraphQL-IO. Please check out GraphQL-IO-Client and GraphQL-IO-Server for the real client and server implementation packages!

About

This is a GraphQL-based network communication framework for JavaScript clients, running under either Node.js or in the Browser, and JavaScript servers, running under Node.js. The client-side is provided by the module GraphQL-IO-Client, the server-side is provided by the module GraphQL-IO-Server. This is just a meta-package which bundles the server and client packages for being able to conveniently reference both the server and the client in their latest versions through a single package. Feel free to just use (particular versions of) the individual packages directly.

On the client-side, it is based on the GraphQL engine GraphQL.js, the GraphQL client library Apollo Client, its WebSocket network interface Apollo Client WS and the HTTP client library Axios.

On the server-side, it is based on the GraphQL engine GraphQL.js, the GraphQL schema execution library GraphQL-Tools, the GraphQL type definition library GraphQL-Tools-Types, the GraphQL subscription management library GraphQL-Tools-Subscribe, the network communication framework HAPI, the WebSocket integration plugin HAPI-Plugin-WebSocket and the GraphiQL integration plugin HAPI-Plugin-GraphiQL.

Installation

# all-in-one
$ npm install graphql-io

# client-side only
$ npm install graphql-io-client

Sample

/*  Hello World Server  */
const { Server } = require("graphql-io-server")
const server = new Server({ url: "http://127.0.0.1:12345/api" })
server.at("graphql-resolver", () => ({
    Root: { hello: [ "hello: String", () => "world" ] }
}))
await server.start()

/*  Hello World Client  */
const { Client } = require("graphql-io-client")
const client = new Client({ url: "http://127.0.0.1:12345/api" })
await client.connect()
let result = await client.query("{ hello }")
await client.disconnect()
console.log(result.data)

For more elaborate samples, check out the Samples folder. These samples show a minimum Hello World, subscriptions over separate client connections, real-time performance of server, usage from within Node.js and the Browser, etc.
