@hora-engine/graph-core

Bio-inspired embedded knowledge graph engine for Node.js — powered by Rust via napi-rs.

Install

npm install @hora-engine/graph-core

Quick start

const { HoraCore } = require('@hora-engine/graph-core');

const graph = new HoraCore();

// Add entities
const alice = graph.addEntity('person', { name: 'Alice' });
const bob = graph.addEntity('person', { name: 'Bob' });

// Add edge
graph.addEdge(alice, bob, 'knows', { since: 2024 });

// Traverse
const friends = graph.neighbors(alice, { edgeType: 'knows' });

Features

• Knowledge graph — entities, edges, properties, bi-temporal versioning
• Vector search — SIMD-accelerated cosine similarity
• BM25 full-text — Okapi BM25+ ranking
• Hybrid search — RRF fusion of vector + text
• Memory model — ACT-R activation, spreading, FSRS scheduling
• Consolidation — SHY downscaling, interleaved replay, dream cycle
• Storage — embedded pages, SQLite, PostgreSQL
