🚀 Usage Examples

Quick Start (OpenAI)

import { OpenAIEmbeddings } from 'ruvector-extensions';

const openai = new OpenAIEmbeddings({
  apiKey: process.env.OPENAI_API_KEY,
});

const embedding = await openai.embedText('Hello, world!');
// Returns: number[] (1536 dimensions)

VectorDB Integration

import { VectorDB } from 'ruvector';
import { OpenAIEmbeddings, embedAndInsert } from 'ruvector-extensions';

const openai = new OpenAIEmbeddings({ apiKey: '...' });
const db = new VectorDB({ dimension: 1536 });

const ids = await embedAndInsert(db, openai, [
  { id: '1', text: 'Document 1', metadata: { ... } },
  { id: '2', text: 'Document 2', metadata: { ... } },
]);

Local Embeddings (No API)

import { HuggingFaceEmbeddings } from 'ruvector-extensions';

const hf = new HuggingFaceEmbeddings();
const embedding = await hf.embedText('Privacy-friendly local embedding');
// No API key required!

🔧 Configuration Options

Provider-Specific Configs

OpenAI:

• apiKey: string (required)
• model: 'text-embedding-3-small' | 'text-embedding-3-large' | 'text-embedding-ada-002'
• dimensions: number (only for 3-small/large)
• organization: string (optional)
• baseURL: string (optional)

Cohere:

• apiKey: string (required)
• model: 'embed-english-v3.0' | 'embed-multilingual-v3.0'
• inputType: 'search_document' | 'search_query' | 'classification' | 'clustering'
• truncate: 'NONE' | 'START' | 'END'

Anthropic/Voyage:

• apiKey: string (Voyage API key)
• model: 'voyage-2'
• inputType: 'document' | 'query'

HuggingFace:

• model: string (default: 'Xenova/all-MiniLM-L6-v2')
• normalize: boolean (default: true)
• batchSize: number (default: 32)

Retry Configuration (All Providers)

retryConfig: {
  maxRetries: 3,           // Max retry attempts
  initialDelay: 1000,      // Initial delay (ms)
  maxDelay: 10000,         // Max delay (ms)
  backoffMultiplier: 2,    // Exponential factor
}

🔐 Security Considerations

1. API Key Management

   • Use environment variables
   • Never commit keys to version control
   • Implement key rotation

2. Data Privacy

   • Consider local models (HuggingFace) for sensitive data
   • Review provider data policies
   • Implement data encryption at rest

3. Rate Limiting

   • Automatic retry with backoff
   • Configurable batch sizes
   • Progress tracking for monitoring

📦 Dependencies

Required

• ruvector: ^0.1.20 (core vector database)
• @anthropic-ai/sdk: ^0.24.0 (for Anthropic provider)

Optional Peer Dependencies

• openai: ^4.0.0 (for OpenAI provider)
• cohere-ai: ^7.0.0 (for Cohere provider)
• @xenova/transformers: ^2.17.0 (for HuggingFace local models)

Development

• typescript: ^5.3.3
• @types/node: ^20.10.5

🎯 Future Enhancements

Potential improvements for future versions:

1. Additional provider support (Azure OpenAI, AWS Bedrock)
2. Streaming API for real-time embeddings
3. Caching layer for duplicate texts
4. Metrics and observability hooks
5. Multi-modal embeddings (text + images)
6. Fine-tuning support
7. Embedding compression techniques
8. Semantic deduplication

📈 Performance Benchmarks

Expected performance (approximate):

• Small batch (10 texts): < 500ms
• Medium batch (100 texts): 1-2 seconds
• Large batch (1000 texts): 10-20 seconds
• Massive batch (10000 texts): 2-3 minutes

Times vary by provider, network latency, and text length

🤝 Integration Points

The module integrates seamlessly with:

• ✅ ruvector VectorDB core
• ✅ ruvector-extensions temporal tracking
• ✅ ruvector-extensions persistence layer
• ✅ ruvector-extensions UI server
• ✅ Standard VectorDB query interfaces
