graphql-ld-comunica-solid v2.0.1

Comunica with Solid authentication for GraphQL-LD

This is a GraphQL-LD engine for executing queries using the Comunica query engine with Solid authentication.

This tool is identical to graphql-ld-comunica, with the additional feature that HTTP requests are authenticated using Comunica SPARQL Solid.

Usage

This requires you to install graphql-ld-comunica-solid: yarn add graphql-ld-comunica-solid.

import {Client} from "graphql-ld";
import {QueryEngineComunicaSolid} from "graphql-ld-comunica-solid";
import {interactiveLogin} from "solid-node-interactive-auth";

// Define a JSON-LD context
const context = {
  "@context": {
    "rdfs": "http://www.w3.org/2000/01/rdf-schema#",
    "label": "rdfs:label",
    "foaf": "http://xmlns.com/foaf/0.1/",
    "name": "foaf:name",
    "img": "foaf:img",
    "interests": "foaf:topic_interest",
    "RUBEN": { "@id": "https://www.rubensworks.net/#me" }
  }
};

// Create a GraphQL-LD client based on a client-side Comunica engine over 2 sources
const comunicaConfig = {
  sources: [
    "https://www.rubensworks.net/",
    "http://fragments.dbpedia.org/2016-04/en",
  ],
  // This will open your Web browser to log in.
  // Other mechanisms to obtain your session may also be used instead.
  session: await interactiveLogin({ oidcIssuer: 'https://solidcommunity.net/' }),
};
const client = new Client({ context, queryEngine: new QueryEngineComunicaSolid(comunicaConfig) });

// Define a query
const query = `
  query @single {
    id(_:RUBEN)
    name @single
    img @single
    interests {
      id @single
      label @single
    }
  }`;

// Execute the query
const { data } = await client.query({ query });
