GraphQL client over HTTP/WS

Node.js with HTTP and WS links, context, and retry options

import { createGraphQLClient } from "graphql-http-ws-client";
import WebSocket from "ws";
import fetch from "node-fetch";

let addContext = async () => {
	return {
		headers: {
			Authorization: `Bearer MYAUTHTOKEN`
		}
	}
};

const { client } = createGraphQLClient("MY_GRAPHQL_URL", {
	createWSLink: true,
    createHTTPLink: true,
    websocket: WebSocket,
    httpLinkOptions: {
        fetch: fetch,
        setContext: addContext
    },
    wsLinkOptions: {
        connectionParams: addContext
    },
    retryLinkOptions: {
        delay: {
          initial: 300,
          max: 6000,
          jitter: true
        },
        attempts: {
          max: Infinity
        }
    }
});

Node.js with HTTP link only (no Subscriptions)

import { createGraphQLClient } from "graphql-http-ws-client";
import fetch from "node-fetch";

const { client } = createGraphQLClient("MY_GRAPHQL_URL", {
	httpLinkOptions: {
	    fetch: fetch
	},
	createWSLink: false
});

Node.js with WS link only

import { createGraphQLClient } from "graphql-http-ws-client";
import WebSocket from "ws";
import fetch from "node-fetch";

const { client } = createGraphQLClient("MY_GRAPHQL_URL", {
	websocket: WebSocket,
	createHTTPLink: false
});

Node.js with WS link and graphql-transport-ws subprotocol

import { createGraphQLClient } from "graphql-http-ws-client";
import WebSocket from "ws";
import fetch from "node-fetch";

const { client } = createGraphQLClient("MY_GRAPHQL_URL", {
	websocket: WebSocket,
    wsSubprotocol: "graphql-transport-ws",
	createHTTPLink: false
});

Node.js with WS link and graphql-ws subprotocol (default)

import { createGraphQLClient } from "graphql-ws";
import WebSocket from "ws";
import fetch from "node-fetch";

const { client } = createGraphQLClient("MY_GRAPHQL_URL", {
	websocket: WebSocket,
    wsSubprotocol: "graphql-ws",
	createHTTPLink: false
});

React with HTTP and WS links

import WebSocket from "ws";
import fetch from "node-fetch";
import {createGraphQLClient, gql} from "graphql-http-ws-client";
import { persistCache } from "apollo-cache-persist";
const { client, cache } = createGraphQLClient("MY_GRAPHQL_URL");

const waitOnCache = persistCache({
	cache: cache,
	storage: window.localStorage
});

waitOnCache.then(() => {
	ReactDOM.render(
		<ApolloProvider client={client}>
			<Router>
				<App/>
			</Router>
		</ApolloProvider>,
		document.getElementById('root')
	)
});

Simple Queries

Using the server example from graphql-http-ws-server

client.query({
    query: `query {
        hello
    }`
}).then(({data}) => {
    console.log("DATA", data);
});

Simple Subscriptions

Using the server example from graphql-http-ws-server

client.subscribe({
    query: `subscription {
        time
    }`
}).subscribe({
    next({data}) {
        console.log(data);
    }
});

v2.0

• Changed package type to module
• Passed-in queries and mutations are now automatically wrapped with gql() tag, if they are not already wrapped

v0.3

• Module now exports gql and all exports from @apollo/client/core
