💚 CogniDB Official Node.js SDK (npm install cognidb-client)

Official Node.js Client for CogniDB—the AI-Native Unified Database Engine.

CogniDB unifies relational SQL queries, HNSW vector similarity search (SIMILAR TO), in-memory key-value caching, and in-engine AI RAG into a single low-latency engine.

⚡ Quick Start

1. Installation

npm install cognidb-client

2. Usage Example

const { CogniDBClient } = require('cognidb-client');

// Initialize CogniDB Client
const client = new CogniDBClient({ host: 'http://localhost:8080' });

async function runDemo() {
    // 1. Execute SQL Query
    const createRes = await client.query(`
        CREATE TABLE IF NOT EXISTS node_services (
            id VARCHAR PRIMARY KEY,
            name VARCHAR,
            region VARCHAR,
            latency_ms FLOAT,
            embedding FLOAT_VECTOR(128)
        );
    `);
    console.log('Table Created:', createRes);

    // 2. Perform HNSW Vector Similarity Search
    const searchResults = await client.vectorSearch(
        'node_services',
        'authentication microservice',
        1,
        "region = 'us-east-1'"
    );
    console.log('Vector Search Results:', searchResults);
}

runDemo().catch(console.error);
