A GraphQL-LD engine that is backed by Comunica with Solid authentication
npm install graphql-ld-comunica-solid
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.
_This requires you to install graphql-ld-comunica-solid: yarn add graphql-ld-comunica-solid._
