hnswlib-node

npm version Build Status License Documentation

hnswlib-node provides Node.js bindings for Hnswlib that implements approximate nearest-neighbor search based on hierarchical navigable small world graphs.

Installation

sh $ npm install hnswlib-node

Documentation

Usage

Generating search index:

```typescript import { HierarchicalNSW } from 'hnswlib-node';

const numDimensions = 8; // the length of data point vector that will be indexed. const maxElements = 10; // the maximum number of data points.

// declaring and intializing index. const index = new HierarchicalNSW('l2', numDimensions); index.initIndex(maxElements);

// inserting data points to index. for (let i = 0; i < maxElements; i++) { const point = new Array(numDimensions); for (let j = 0; j < numDimensions; j++) point[j] = Math.random(); index.addPoint(point, i); }

// saving index. index.writeIndexSync('foo.dat'); ```

Searching nearest neighbors:

```typescript import { HierarchicalNSW } from 'hnswlib-node';

// loading index. const index = new HierarchicalNSW('l2', 3); index.readIndexSync('foo.dat');

// preparing query data points. const numDimensions = 8; const query = new Array(numDimensions); for (let j = 0; j < numDimensions; j++) query[j] = Math.random();

// searching k-nearest neighbor data points. const numNeighbors = 3; const result = index.searchKnn(query, numNeighbors);

console.table(result); ```
