    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(' '));

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);

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
});

  • 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
