Blazegraph JavaScript API

Blazegraph JavaScript API. This version has been completely rewritten and the new API is still evolving.

Installation

yarn add https://github.com/seronet-project/blazegraph-js

Usage

Many (undocumented yet) methods are available. Have a look at the source for more info.

preparation

const { prepareBlaze } = require("blazegraph");
const { SELECT, UPDATE } = prepareBlaze({
  host: "localhost",
  port: 9999,
  namespace: "kb" // Those are the default values, passing no params yields the same result
});

sparql query - output written to the console

// simple async example
const results = await SELECT`select * { ?s ?p ?o } limit 10`;
console.log(results);

sparql query - asynchronous pipeline with ramda

const { pipeP, pluck } = require("ramda");
await pipeP(
  () => SELECT`select * {?s ?p ?o}`, // 1. query
  pluck("p"), // 2. extract only properties
  pluck("value"), // 3. extract value from each property
  console.log // 4. write results to console
)();

Note

Unstable, do not use in production! The current API is quite specific to Nelson, but feel free to PR breaking changes to make it universal.
