tree-to-sparqljson is a utility package that converts GraphQL JSON tree results into SPARQL JSON results.

Installation

Usage

import { Converter } from 'tree-to-sparqljson';

const converter = new Converter();

const graphqlTreeResult = {
  "data": {
    "Person": [
      {
        "id": "http://example.org/alice",
        "givenName": [
            "Alice"
        ]
