## 🚀 Usage Examples
|
||||
|
||||
### Quick Start (OpenAI)
|
||||
```typescript
|
||||
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
|
||||
```typescript
|
||||
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)
|
||||
```typescript
|
||||
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
|
||||
|
||||

|
||||
- `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:**
|
||||

|
||||
- `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:**
|
||||

|
||||
- `normalize`: boolean (default: true)
|
||||
- `batchSize`: number (default: 32)
|
||||
|
||||
### Retry Configuration (All Providers)
|
||||
```typescript
|
||||
retryConfig: {
|
||||
maxRetries: 3, // Max retry attempts
|
||||
initialDelay: 1000, // Initial delay (ms)
|
||||
maxDelay: 10000, // Max delay (ms)
|
||||
backoffMultiplier: 2, // Exponential factor
|
||||
}
|
||||
```
|
||||
|
||||
## 📊 Performance Characteristics

|
||||
- 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
|
||||
|
||||
