Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

⚡ Quick Start

JavaScript (CommonJS)

const { VectorDB } = require('ruvector');

async function main() {
  // Create database with 384 dimensions (e.g., for sentence-transformers)
  const db = VectorDB.withDimensions(384);

  // Insert vectors with metadata
  const id1 = await db.insert({
    vector: new Float32Array(384).fill(0.1),
    metadata: { text: 'Hello world', category: 'greeting' }
  });

  const id2 = await db.insert({
    vector: new Float32Array(384).fill(0.2),
    metadata: { text: 'Goodbye world', category: 'farewell' }
  });

  console.log(`Inserted: ${id1}, ${id2}`);

  // Search for similar vectors
  const results = await db.search({
    vector: new Float32Array(384).fill(0.15),
    k: 10,
    filter: { category: 'greeting' }
  });

  results.forEach(result => {
    console.log(`ID: ${result.id}, Score: ${result.score}`);
    console.log(`Metadata:`, result.metadata);
  });

  // Get database stats
  console.log(`Total vectors: ${await db.len()}`);
}

main().catch(console.error);

TypeScript (ESM)

import { VectorDB, JsDbOptions, JsSearchQuery } from 'ruvector';

interface DocumentMetadata {
  text: string;
  category: string;
  timestamp: number;
}

async function semanticSearch() {
  // Advanced configuration
  const options: JsDbOptions = {
    dimensions: 768,
    distanceMetric: 'Cosine',
    storagePath: './my-vectors.db',
    hnswConfig: {
      m: 32,              // Connections per layer
      efConstruction: 200, // Build quality
      efSearch: 100        // Search quality
    },
    quantization: {
      type: 'product',
      subspaces: 16,
      k: 256
    }
  };

  const db = new VectorDB(options);

  // Batch insert for better performance
  const embeddings = await getEmbeddings(['doc1', 'doc2', 'doc3']);
  const ids = await db.insertBatch(
    embeddings.map((vec, i) => ({
      vector: new Float32Array(vec),
      metadata: {
        text: `Document ${i}`,
        category: 'article',
        timestamp: Date.now()
      }
    }))
  );

  console.log(`Inserted ${ids.length} vectors`);

  // Semantic search with filters
  const query: JsSearchQuery = {
    vector: new Float32Array(await getEmbedding('search query')),
    k: 10,
    filter: { category: 'article' },
    efSearch: 150  // Higher = more accurate but slower
  };

  const results = await db.search(query);

  return results.map(r => ({
    id: r.id,
    similarity: 1 - r.score,  // Convert distance to similarity
    metadata: r.metadata as DocumentMetadata
  }));
}

// Helper function (replace with your embedding model)
async function getEmbedding(text: string): Promise<number[]> {
  // Use OpenAI, Cohere, or local model like sentence-transformers
  return new Array(768).fill(0);
}

async function getEmbeddings(texts: string[]): Promise<number[][]> {
  return Promise.all(texts.map(getEmbedding));
}

📖 API Reference

VectorDB Class

Constructor

// Option 1: Full configuration
const db = new VectorDB({
  dimensions: 384,                    // Required: Vector dimensions
  distanceMetric?: 'Euclidean' | 'Cosine' | 'DotProduct' | 'Manhattan',
  storagePath?: string,               // Default: './ruvector.db'
  hnswConfig?: {
    m?: number,              // Default: 32 (16-64 recommended)
    efConstruction?: number, // Default: 200 (100-500)
    efSearch?: number,       // Default: 100 (50-500)
    maxElements?: number     // Default: 10,000,000
  },
  quantization?: {
    type: 'none' | 'scalar' | 'product' | 'binary',
    subspaces?: number,      // For product quantization (Default: 16)
    k?: number               // Codebook size (Default: 256)
  }
});

// Option 2: Simple factory method (uses defaults)
const db = VectorDB.withDimensions(384);

Configuration Guide:

  • dimensions: Must match your embedding model output (e.g., 384 for all-MiniLM-L6-v2, 768 for BERT, 1536 for OpenAI text-embedding-3-small)
  • distanceMetric:
    • Cosine: Best for normalized vectors (text embeddings, most ML models) - Default
    • Euclidean: Best for absolute distances (images, spatial data)
    • DotProduct: Best for positive vectors with magnitude info
    • Manhattan: Best for sparse vectors (L1 norm)
  • storagePath: Path to persistent storage file
  • hnswConfig: Controls search quality and speed tradeoff
  • quantization: Enables memory compression (4-32x reduction)

Methods

insert(entry): Promise<string>

Insert a single vector and return its ID.

const id = await db.insert({
  id?: string,                    // Optional (auto-generated UUID if not provided)
  vector: Float32Array,           // Required: Vector data
  metadata?: Record<string, any>  // Optional: JSON object
});

Example:

const id = await db.insert({
  vector: new Float32Array([0.1, 0.2, 0.3, ...]),
  metadata: {
    text: 'example document',
    category: 'research',
    timestamp: Date.now()
  }
});
console.log(`Inserted with ID: ${id}`);
insertBatch(entries): Promise<string[]>

Insert multiple vectors efficiently in a batch (10-50x faster than sequential inserts).

const ids = await db.insertBatch([
  { vector: new Float32Array([...]) },
  { vector: new Float32Array([...]), metadata: { text: 'example' } }
]);

Example:

// Bad: Sequential inserts (slow)
for (const vector of vectors) {
  await db.insert({ vector });  // Don't do this!
}

// Good: Batch insert (10-50x faster)
await db.insertBatch(
  vectors.map(v => ({ vector: new Float32Array(v) }))
);
search(query): Promise<SearchResult[]>

Search for similar vectors using HNSW approximate nearest neighbor search.

const results = await db.search({
  vector: Float32Array,           // Required: Query vector
  k: number,                      // Required: Number of results
  filter?: Record<string, any>,   // Optional: Metadata filters
  efSearch?: number               // Optional: HNSW search parameter (higher = more accurate)
});

// Result format:
interface SearchResult {
  id: string;           // Vector ID
  score: number;        // Distance (lower is better for most metrics)
  vector?: number[];    // Original vector (optional, for debugging)
  metadata?: any;       // Metadata object
}

Example:

const results = await db.search({
  vector: queryEmbedding,
  k: 10,
  filter: { category: 'research', year: 2024 },
  efSearch: 150  // Higher = better recall, slower search
});

results.forEach(result => {
  const similarity = 1 - result.score;  // Convert distance to similarity
  console.log(`${result.metadata.text}: ${similarity.toFixed(3)}`);
});
get(id): Promise<VectorEntry | null>

Retrieve a vector by ID.

const entry = await db.get('vector-id');
if (entry) {
  console.log(entry.vector, entry.metadata);
}
delete(id): Promise<boolean>

Delete a vector by ID. Returns true if deleted, false if not found.

const deleted = await db.delete('vector-id');
console.log(deleted ? 'Deleted' : 'Not found');
len(): Promise<number>

Get the total number of vectors in the database.

const count = await db.len();
console.log(`Database contains ${count} vectors`);
isEmpty(): Promise<boolean>

Check if the database is empty.

if (await db.isEmpty()) {
  console.log('No vectors yet');
}

Utility Functions

version(): string

Get the Ruvector library version.

import { version } from 'ruvector';
console.log(`Ruvector v${version()}`);

🎯 Common Use Cases

1. RAG (Retrieval-Augmented Generation)

Build production-ready RAG systems with fast vector retrieval for LLMs.

const { VectorDB } = require('ruvector');
const { OpenAI } = require('openai');

class RAGSystem {
  constructor() {
    this.db = VectorDB.withDimensions(1536); // OpenAI embedding size
    this.openai = new OpenAI();
  }

  async indexDocument(text, metadata) {
    // Split into chunks (use better chunking in production)
    const chunks = this.chunkText(text, 512);

    // Get embeddings from OpenAI
    const embeddings = await this.openai.embeddings.create({
      model: 'text-embedding-3-small',
      input: chunks
    });

    // Insert into vector DB
    const ids = await this.db.insertBatch(
      embeddings.data.map((emb, i) => ({
        vector: new Float32Array(emb.embedding),
        metadata: { ...metadata, chunk: i, text: chunks[i] }
      }))
    );

    return ids;
  }

  async query(question, k = 5) {
    // Embed the question
    const response = await this.openai.embeddings.create({
      model: 'text-embedding-3-small',
      input: [question]
    });

    // Search for relevant chunks
    const results = await this.db.search({
      vector: new Float32Array(response.data[0].embedding),
      k
    });

    // Extract context
    const context = results
      .map(r => r.metadata.text)
      .join('\n\n');

    // Generate answer with LLM
    const completion = await this.openai.chat.completions.create({
      model: 'gpt-4',
      messages: [
        { role: 'system', content: 'Answer based on the context provided.' },
        { role: 'user', content: `Context:\n${context}\n\nQuestion: ${question}` }
      ]
    });

    return {
      answer: completion.choices[0].message.content,
      sources: results.map(r => r.metadata)
    };
  }

  chunkText(text, maxLength) {
    // Simple word-based chunking
    const words = text.split(' ');
    const chunks = [];
    let current = [];

    for (const word of words) {
      current.push(word);
      if (current.join(' ').length > maxLength) {
        chunks.push(current.join(' '));
        current = [];
      }
    }

    if (current.length > 0) {
      chunks.push(current.join(' '));
    }

    return chunks;
  }
}

// Usage
const rag = new RAGSystem();
await rag.indexDocument('Long document text...', { source: 'doc.pdf' });
const result = await rag.query('What is the main topic?');
console.log(result.answer);
console.log('Sources:', result.sources);

2. Semantic Code Search

Find similar code patterns across your codebase.

import { VectorDB } from 'ruvector';
import { pipeline } from '@xenova/transformers';

// Use a code-specific embedding model
const embedder = await pipeline(
  'feature-extraction',
  'Xenova/codebert-base'
);

const db = VectorDB.withDimensions(768);

// Index code snippets
async function indexCodebase(codeFiles: Array<{ path: string, code: string }>) {
  for (const file of codeFiles) {
    const embedding = await embedder(file.code, {
      pooling: 'mean',
      normalize: true
    });

    await db.insert({
      vector: new Float32Array(embedding.data),
      metadata: {
        path: file.path,
        code: file.code,
        language: file.path.split('.').pop()
      }
    });
  }
}

// Search for similar code
async function findSimilarCode(query: string, k = 10) {
  const embedding = await embedder(query, {
    pooling: 'mean',
    normalize: true
  });

  const results = await db.search({
    vector: new Float32Array(embedding.data),
    k
  });

  return results.map(r => ({
    path: r.metadata.path,
    code: r.metadata.code,
    similarity: 1 - r.score
  }));
}

// Example usage
await indexCodebase([
  { path: 'utils.ts', code: 'function parseJSON(str) { ... }' },
  { path: 'api.ts', code: 'async function fetchData(url) { ... }' }
]);

const similar = await findSimilarCode('parse JSON string');
console.log(similar);

3. Recommendation System

Build personalized recommendation engines.

const { VectorDB } = require('ruvector');

class RecommendationEngine {
  constructor() {
    // User/item embeddings from collaborative filtering or content features
    this.db = VectorDB.withDimensions(128);
  }

  async addItem(itemId, features, metadata) {
    await this.db.insert({
      id: itemId,
      vector: new Float32Array(features),
      metadata: {
        ...metadata,
        addedAt: Date.now()
      }
    });
  }

  async recommendSimilar(itemId, k = 10, filters = {}) {
    // Get the item's embedding
    const item = await this.db.get(itemId);
    if (!item) return [];

    // Find similar items
    const results = await this.db.search({
      vector: item.vector,
      k: k + 1, // +1 because it will include itself
      filter: filters
    });

    // Remove the item itself from results
    return results
      .filter(r => r.id !== itemId)
      .slice(0, k)
      .map(r => ({
        id: r.id,
        similarity: 1 - r.score,
        ...r.metadata
      }));
  }

  async recommendForUser(userVector, k = 10, category = null) {
    const filter = category ? { category } : undefined;

    const results = await this.db.search({
      vector: new Float32Array(userVector),
      k,
      filter
    });

    return results.map(r => ({
      id: r.id,
      score: 1 - r.score,
      ...r.metadata
    }));
  }
}

// Usage
const engine = new RecommendationEngine();

// Add products
await engine.addItem('prod-1', new Array(128).fill(0.1), {
  name: 'Laptop',
  category: 'electronics',
  price: 999
});

// Get similar products
const similar = await engine.recommendSimilar('prod-1', 5, {
  category: 'electronics'
});

// Get recommendations for user
const userPreferences = new Array(128).fill(0.15); // From ML model
const recommended = await engine.recommendForUser(userPreferences, 10);

4. Duplicate Detection

Find and deduplicate similar documents or records.

import { VectorDB } from 'ruvector';

class DuplicateDetector {
  private db: VectorDB;
  private threshold: number;

  constructor(dimensions: number, threshold = 0.95) {
    this.db = VectorDB.withDimensions(dimensions);
    this.threshold = threshold;  // Similarity threshold
  }

  async addDocument(id: string, embedding: Float32Array, metadata: any) {
    // Check for duplicates before adding
    const duplicates = await this.findDuplicates(embedding, 1);

    if (duplicates.length > 0) {
      return {
        added: false,
        duplicate: duplicates[0]
      };
    }

    await this.db.insert({ id, vector: embedding, metadata });
    return { added: true };
  }

  async findDuplicates(embedding: Float32Array, k = 5) {
    const results = await this.db.search({
      vector: embedding,
      k
    });

    return results
      .filter(r => (1 - r.score) >= this.threshold)
      .map(r => ({
        id: r.id,
        similarity: 1 - r.score,
        metadata: r.metadata
      }));
  }
}

// Usage
const detector = new DuplicateDetector(384, 0.95);
const result = await detector.addDocument(
  'doc-1',
  documentEmbedding,
  { text: 'Example document' }
);

if (!result.added) {
  console.log('Duplicate found:', result.duplicate);
}

🔧 Performance Tuning

HNSW Parameters

Tune the HNSW index for your specific use case:

// High-recall configuration (research, critical applications)
const highRecallDb = new VectorDB({
  dimensions: 384,
  hnswConfig: {
    m: 64,              // More connections = better recall
    efConstruction: 400, // Higher quality index build
    efSearch: 200        // More thorough search
  }
});

// Balanced configuration (most applications) - DEFAULT
const balancedDb = new VectorDB({
  dimensions: 384,
  hnswConfig: {
    m: 32,
    efConstruction: 200,
    efSearch: 100
  }
});

// Speed-optimized configuration (real-time applications)
const fastDb = new VectorDB({
  dimensions: 384,
  hnswConfig: {
    m: 16,              // Fewer connections = faster
    efConstruction: 100,
    efSearch: 50         // Faster search, slightly lower recall
  }
});

Parameter Guide:

  • m (16-64): Number of connections per node

    • Higher = better recall, more memory, slower inserts
    • Lower = faster inserts, less memory, slightly lower recall
  • efConstruction (100-500): Quality of index construction

    • Higher = better index quality, slower builds
    • Lower = faster builds, slightly lower recall
  • efSearch (50-500): Search quality parameter

    • Higher = better recall, slower searches
    • Lower = faster searches, slightly lower recall
    • Can be overridden per query

Quantization for Large Datasets

Reduce memory usage by 4-32x with quantization:

// Product Quantization: 8-32x memory compression
const pqDb = new VectorDB({
  dimensions: 768,
  quantization: {
    type: 'product',
    subspaces: 16,    // 768 / 16 = 48 dims per subspace
    k: 256            // 256 centroids (8-bit quantization)
  }
});

// Binary Quantization: 32x compression, very fast (best for Cosine)
const binaryDb = new VectorDB({
  dimensions: 384,
  quantization: { type: 'binary' }
});

// Scalar Quantization: 4x compression, minimal accuracy loss
const scalarDb = new VectorDB({
  dimensions: 384,
  quantization: { type: 'scalar' }
});

// No Quantization: Maximum accuracy, more memory
const fullDb = new VectorDB({
  dimensions: 384,
  quantization: { type: 'none' }
});

Quantization Guide:

  • Product: Best for large datasets (>100K vectors), 8-32x compression
  • Binary: Fastest search, 32x compression, works best with Cosine metric
  • Scalar: Good balance (4x compression, <1% accuracy loss)
  • None: Maximum accuracy, no compression

Batch Operations

Always use batch operations for better performance:

// ❌ Bad: Sequential inserts (slow)
for (const vector of vectors) {
  await db.insert({ vector });
}

// ✅ Good: Batch insert (10-50x faster)
await db.insertBatch(
  vectors.map(v => ({ vector: new Float32Array(v) }))
);

Distance Metrics

Choose the right metric for your embeddings:

// Cosine: Best for normalized vectors (text embeddings, most ML models)
const cosineDb = new VectorDB({
  dimensions: 384,
  distanceMetric: 'Cosine'  // Range: [0, 2], lower is better
});

// Euclidean: Best for absolute distances (images, spatial data)
const euclideanDb = new VectorDB({
  dimensions: 384,
  distanceMetric: 'Euclidean'  // Range: [0, ∞], lower is better
});

// DotProduct: Best for positive vectors with magnitude info
const dotProductDb = new VectorDB({
  dimensions: 384,
  distanceMetric: 'DotProduct'  // Range: (-∞, ∞), higher is better
});

// Manhattan: Best for sparse vectors (L1 norm)
const manhattanDb = new VectorDB({
  dimensions: 384,
  distanceMetric: 'Manhattan'  // Range: [0, ∞], lower is better
});

🐛 Troubleshooting

Installation fails

Error: Cannot find module 'ruvector'

Make sure you have Rust installed:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env

Build errors

Error: error: linking with 'cc' failed

Install build tools:

# Linux (Ubuntu/Debian)
sudo apt-get install build-essential

# macOS
xcode-select --install

# Windows
# Install Visual Studio Build Tools

Update NAPI-RS CLI:

npm install -g @napi-rs/cli

Performance issues

  • ✅ Use HNSW indexing for datasets >10K vectors
  • ✅ Enable quantization for large datasets
  • ✅ Adjust efSearch for speed/accuracy tradeoff
  • ✅ Use insertBatch instead of individual insert calls
  • ✅ Use appropriate distance metric for your embeddings
  • ✅ Consider product quantization for >100K vectors

Memory issues

  • ✅ Enable product quantization (8-32x compression)
  • ✅ Reduce m parameter in HNSW config
  • ✅ Use binary quantization for maximum compression
  • ✅ Batch operations to reduce memory overhead
