🌟 Why Ruvector?

The Problem with Existing Vector Databases

Most vector databases force you to choose between three painful trade-offs:

1. Cloud-Only Services (Pinecone, Weaviate Cloud) - Expensive, vendor lock-in, latency issues, API rate limits
2. Python-First Solutions (ChromaDB, Faiss) - Poor Node.js support, require separate Python processes
3. Self-Hosted Complexity (Milvus, Qdrant) - Heavy infrastructure, Docker orchestration, operational overhead

Ruvector eliminates these trade-offs.

Step 2: Your First Vector Database

Let's create a simple vector database and perform basic operations. This example demonstrates the complete CRUD (Create, Read, Update, Delete) workflow:

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

async function tutorial() {
  // Step 2.1: Create a new vector database
  // The 'dimensions' parameter must match your embedding model
  // Common sizes: 128, 384 (sentence-transformers), 768 (BERT), 1536 (OpenAI)
  const db = new VectorDb({
    dimensions: 128,           // Vector size - MUST match your embeddings
    maxElements: 10000,        // Maximum vectors (can grow automatically)
    storagePath: './my-vectors.db'  // Persist to disk (omit for in-memory)
  });

  console.log('✅ Database created successfully');

  // Step 2.2: Insert vectors
  // In real applications, these would come from an embedding model
  const documents = [
    { id: 'doc1', text: 'Artificial intelligence and machine learning' },
    { id: 'doc2', text: 'Deep learning neural networks' },
    { id: 'doc3', text: 'Natural language processing' },
  ];

  for (const doc of documents) {
    // Generate random vector for demonstration
    // In production: use OpenAI, Cohere, or sentence-transformers
    const vector = new Float32Array(128).map(() => Math.random());

    await db.insert({
      id: doc.id,
      vector: vector,
      metadata: {
        text: doc.text,
        timestamp: Date.now(),
        category: 'AI'
      }
    });

    console.log(`✅ Inserted: ${doc.id}`);
  }

  // Step 2.3: Search for similar vectors
  // Create a query vector (in production, this would be from your search query)
  const queryVector = new Float32Array(128).map(() => Math.random());

  const results = await db.search({
    vector: queryVector,
    k: 5,              // Return top 5 most similar vectors
    threshold: 0.7     // Only return results with similarity > 0.7
  });

  console.log('\n🔍 Search Results:');
  results.forEach((result, index) => {
    console.log(`${index + 1}. ${result.id} - Score: ${result.score.toFixed(3)}`);
    console.log(`   Text: ${result.metadata.text}`);
  });

  // Step 2.4: Retrieve a specific vector
  const retrieved = await db.get('doc1');
  if (retrieved) {
    console.log('\n📄 Retrieved document:', retrieved.metadata.text);
  }

  // Step 2.5: Get database statistics
  const count = await db.len();
  console.log(`\n📊 Total vectors in database: ${count}`);

  // Step 2.6: Delete a vector
  const deleted = await db.delete('doc1');
  console.log(`\n🗑️  Deleted doc1: ${deleted ? 'Success' : 'Not found'}`);

  // Final count
  const finalCount = await db.len();
  console.log(`📊 Final count: ${finalCount}`);
}

// Run the tutorial
tutorial().catch(console.error);

Expected Output:

✅ Database created successfully
✅ Inserted: doc1
✅ Inserted: doc2
✅ Inserted: doc3

🔍 Search Results:
1. doc2 - Score: 0.892
   Text: Deep learning neural networks
2. doc1 - Score: 0.856
   Text: Artificial intelligence and machine learning
3. doc3 - Score: 0.801
   Text: Natural language processing

📄 Retrieved document: Artificial intelligence and machine learning

📊 Total vectors in database: 3

🗑️  Deleted doc1: Success
📊 Final count: 2

Step 3: TypeScript Tutorial

Ruvector provides full TypeScript support with complete type safety. Here's how to use it:

import { VectorDb, VectorEntry, SearchQuery, SearchResult } from 'ruvector';

// Step 3.1: Define your custom metadata type
interface DocumentMetadata {
  title: string;
  content: string;
  author: string;
  date: Date;
  tags: string[];
}

async function typescriptTutorial() {
  // Step 3.2: Create typed database
  const db = new VectorDb({
    dimensions: 384,  // sentence-transformers/all-MiniLM-L6-v2
    maxElements: 10000,
    storagePath: './typed-vectors.db'
  });

  // Step 3.3: Type-safe vector entry
  const entry: VectorEntry<DocumentMetadata> = {
    id: 'article-001',
    vector: new Float32Array(384),  // Your embedding here
    metadata: {
      title: 'Introduction to Vector Databases',
      content: 'Vector databases enable semantic search...',
      author: 'Jane Doe',
      date: new Date('2024-01-15'),
      tags: ['database', 'AI', 'search']
    }
  };

  // Step 3.4: Insert with type checking
  await db.insert(entry);
  console.log('✅ Inserted typed document');

  // Step 3.5: Type-safe search
  const query: SearchQuery = {
    vector: new Float32Array(384),
    k: 10,
    threshold: 0.8
  };

  // Step 3.6: Fully typed results
  const results: SearchResult<DocumentMetadata>[] = await db.search(query);

  // TypeScript knows the exact shape of metadata
  results.forEach(result => {
    console.log(`Title: ${result.metadata.title}`);
    console.log(`Author: ${result.metadata.author}`);
    console.log(`Tags: ${result.metadata.tags.join(', ')}`);
    console.log(`Similarity: ${result.score.toFixed(3)}\n`);
  });

  // Step 3.7: Type-safe retrieval
  const doc = await db.get('article-001');
  if (doc) {
    // TypeScript autocomplete works perfectly here
    const publishYear = doc.metadata.date.getFullYear();
    console.log(`Published in ${publishYear}`);
  }
}

typescriptTutorial().catch(console.error);

TypeScript Benefits:

• ✅ Full autocomplete for all methods and properties
• ✅ Compile-time type checking prevents errors
• ✅ IDE IntelliSense shows documentation
• ✅ Custom metadata types for your use case
• ✅ No any types - fully typed throughout

🎯 Platform Detection

Ruvector automatically detects the best implementation for your platform:

const { getImplementationType, isNative, isWasm } = require('ruvector');

console.log(getImplementationType()); // 'native' or 'wasm'
console.log(isNative()); // true if using native Rust
console.log(isWasm()); // true if using WebAssembly fallback

// Performance varies by implementation:
// Native (Rust):  <0.5ms latency, 50K+ ops/sec
// WASM fallback:  10-50ms latency, ~1K ops/sec

When to Choose Ruvector

✅ Perfect for:

• Node.js/TypeScript applications needing embedded vector search
• Serverless and edge computing where external services aren't practical
• Rapid prototyping and development with minimal setup time
• RAG systems with LangChain, LlamaIndex, or custom implementations
• Cost-sensitive projects that can't afford cloud API pricing
• Offline-first applications requiring local vector search
• Browser-based AI with WebAssembly fallback
• Small to medium scale (up to 10M vectors per instance)

⚠️ Consider alternatives for:

• Massive scale (100M+ vectors) - Consider Pinecone, Milvus, or Qdrant clusters
• Multi-tenancy requirements - Weaviate or Qdrant offer better isolation
• Distributed systems - Milvus provides better horizontal scaling
• Zero-ops cloud solution - Pinecone handles all infrastructure

Why Choose Ruvector Over...

vs Pinecone:

• ✅ No API costs (save $1000s/month)
• ✅ No network latency (10x faster queries)
• ✅ No vendor lock-in
• ✅ Works offline and in restricted environments
• ❌ No managed multi-region clusters

vs ChromaDB:

• ✅ 50x faster queries (native Rust vs Python)
• ✅ True Node.js support (not HTTP API)
• ✅ Better TypeScript integration
• ✅ Lower memory usage
• ❌ Smaller ecosystem and community

vs Qdrant:

• ✅ Zero infrastructure setup
• ✅ Embedded in your app (no Docker)
• ✅ Better for serverless environments
• ✅ Native Node.js bindings
• ❌ No built-in clustering or HA

vs Faiss:

• ✅ Full Node.js support (Faiss is Python-only)
• ✅ Easier API and better developer experience
• ✅ Built-in persistence and metadata
• ⚠️ Slightly lower recall at same performance

Tutorial 2: Semantic Search Engine

What you'll learn: Build a semantic search engine that understands meaning, not just keywords.

Prerequisites:

npm install ruvector @xenova/transformers

Complete Implementation:

const { VectorDb } = require('ruvector');
const { pipeline } = require('@xenova/transformers');

class SemanticSearchEngine {
  constructor() {
    this.db = null;
    this.embedder = null;

      dimensions: 384,
      maxElements: 50000,
      storagePath: './semantic-search.db'
    });

    console.log('✅ Search engine ready!\n');
  }

  // Step 2: Generate embeddings
  async embed(text) {

      pooling: 'mean',
      normalize: true
    });

console.log(deleted ? 'Deleted' : 'Not found');

len(): Promise

Get the total number of vectors.

const count = await db.len();
console.log(`Total vectors: ${count}`);

🎨 Advanced Configuration

HNSW Parameters

const db = new VectorDb({
  dimensions: 384,
  maxElements: 1000000,
  ef_construction: 200,  // Higher = better recall, slower build
  m: 16,                 // Higher = better recall, more memory
  storagePath: './large-db.db'
});

Parameter Guidelines:

• ef_construction: 100-400 (higher = better recall, slower indexing)
• m: 8-64 (higher = better recall, more memory)
• Default values work well for most use cases

Distance Metrics

// Cosine similarity (default, best for normalized vectors)
const db1 = new VectorDb({
  dimensions: 128,
  distanceMetric: 'cosine'
});

// Euclidean distance (L2, best for spatial data)
const db2 = new VectorDb({
  dimensions: 128,
  distanceMetric: 'euclidean'
});

// Dot product (best for pre-normalized vectors)
const db3 = new VectorDb({
  dimensions: 128,
  distanceMetric: 'dot'
});

Persistence

// Auto-save to disk
const persistent = new VectorDb({
  dimensions: 128,
  storagePath: './persistent.db'
});

// In-memory only (faster, but data lost on exit)
const temporary = new VectorDb({
  dimensions: 128
  // No storagePath = in-memory
});

Node.js 18+ required for all platforms.

🔧 Building from Source

If you need to rebuild the native module:

# Install Rust toolchain
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Clone repository
git clone https://github.com/ruvnet/ruvector.git
cd ruvector

# Build native module
cd npm/packages/core
npm run build:napi

# Build wrapper package
cd ../ruvector
npm install
npm run build

# Run tests
npm test

Requirements:

• Rust 1.77+
• Node.js 18+
• Cargo

🐛 Troubleshooting

Native Module Not Loading

If you see "Cannot find module 'ruvector-core-*'":

# Reinstall with optional dependencies
npm install --include=optional ruvector

# Verify platform
npx ruvector info

# Check Node.js version (18+ required)
node --version

WASM Fallback Performance

If you're using WASM fallback and need better performance:

1. Install native toolchain for your platform
2. Rebuild native module: npm rebuild ruvector
3. Verify native: npx ruvector info should show "native (Rust)"

Platform Compatibility

• Alpine Linux: Uses WASM fallback (musl not supported)
• Windows ARM: Not yet supported, uses WASM fallback
• Node.js < 18: Not supported, upgrade to Node.js 18+
