|
|
|
|
// 5. Process results
|
|
results.forEach(result => {
|
|
console.log(`ID: ${result.id}`);
|
|
console.log(`Score: ${result.score}`);

## 🔥 Advanced Usage
|
|
|
|
### Web Workers for Background Processing
|
|
|
|
Offload heavy vector operations to background threads for smooth UI performance:
|
|
|
|
```javascript
|
|
// main.js
|
|
import { WorkerPool } from '@ruvector/wasm/worker-pool';
|
|
|
|
const pool = new WorkerPool(
|
|
'/worker.js',
|
|
'/pkg/ruvector_wasm.js',
|
|
{
|
|
poolSize: navigator.hardwareConcurrency || 4, // Auto-detect CPU cores
|
|
dimensions: 384,
|
|
metric: 'cosine',
|
|
useHnsw: true
|
|
}
|
|
);
|
|
|
|
// Initialize worker pool
|
|
await pool.init();
|
|
|
|
// Batch insert in parallel (non-blocking)
|
|
const vectors = generateVectors(10000, 384);
|
|
const ids = await pool.insertBatch(vectors);
|
|
|
|
// Parallel search across workers
|
|
const query = new Float32Array(384).map(() => Math.random());
|
|
const results = await pool.search(query, 100);
|
|
|
|
// Get pool statistics
|
|
const stats = pool.getStats();
|
|
console.log(`Workers: ${stats.busyWorkers}/${stats.poolSize} busy`);
|
|
console.log(`Queue: ${stats.queuedTasks} tasks waiting`);
|
|
|
|
// Cleanup when done
|
|
pool.terminate();
|
|
```
|
|
|
|
```javascript
|
|
// worker.js - Web Worker implementation
|
|
importScripts('/pkg/ruvector_wasm.js');
|
|
|
|
const { VectorDB } = wasm_bindgen;
|
|
|
|
let db = null;
|
|
|
|
self.onmessage = async (e) => {
|
|
const { type, data } = e.data;
|
|
|
|
switch (type) {
|
|
case 'init':
|
|
await wasm_bindgen('/pkg/ruvector_wasm_bg.wasm');
|
|
db = new VectorDB(data.dimensions, data.metric, data.useHnsw);
|
|
self.postMessage({ type: 'ready' });
|
|
break;
|
|
|
|
case 'insert':
|
|
const id = db.insert(data.vector, data.id, data.metadata);
|
|
self.postMessage({ type: 'inserted', id });
|
|
break;
|
|
|
|
case 'search':
|
|
const results = db.search(data.query, data.k);
|
|
self.postMessage({ type: 'results', results });
|
|
break;
|
|
}
|
|
};
|
|
```
|
|
|
|
### IndexedDB Persistence - Offline First
|
|
|
|
Keep your vector database synchronized across sessions:
|
|
|
|
```javascript
|
|
import { IndexedDBPersistence } from '@ruvector/wasm/indexeddb';
|
|
import init, { VectorDB } from '@ruvector/wasm';
|
|
|
|
await init();
|
|
|
|
// Create persistence layer
|
|
const persistence = new IndexedDBPersistence('my_vector_db', {
|
|
version: 1,
|
|
cacheSize: 1000, // LRU cache for hot vectors
|
|
batchSize: 100 // Batch size for bulk operations
|
|
});
|
|
|
|
await persistence.open();
|
|
|
|
// Create or restore VectorDB
|
|
const db = new VectorDB(384, 'cosine', true);
|
|
|
|
// Load existing data from IndexedDB (with progress)
|
|
await persistence.loadAll(async (progress) => {
|
|
console.log(`Loading: ${progress.loaded}/${progress.total} vectors`);
|
|
console.log(`Progress: ${(progress.percent * 100).toFixed(1)}%`);
|
|
|
|
// Insert batch into VectorDB
|
|
if (progress.vectors.length > 0) {
|
|
const ids = db.insertBatch(progress.vectors);
|
|
console.log(`Inserted ${ids.length} vectors`);
|
|
}
|
|
|
|
if (progress.complete) {
|
|
console.log('Database fully loaded!');
|
|
}
|
|
});
|
|
|
|
// Insert new vectors and save to IndexedDB
|
|
const vector = new Float32Array(384).map(() => Math.random());
|
|
const id = db.insert(vector, 'vec_123', { category: 'new' });
|
|
|
|
await persistence.save({
|
|
id,
|
|
vector,
|
|
metadata: { category: 'new' }
|
|
});
|
|
|
|
// Batch save for better performance
|
|
const entries = [...]; // Your vector entries
|
|
await persistence.saveBatch(entries);
|
|
|
|
// Get storage statistics
|
|
const stats = await persistence.getStats();
|
|
console.log(`Total vectors: ${stats.totalVectors}`);
|
|
console.log(`Storage used: ${(stats.storageBytes / 1024 / 1024).toFixed(2)} MB`);
|
|
console.log(`Cache size: ${stats.cacheSize}`);
|
|
console.log(`Cache hit rate: ${(stats.cacheHitRate * 100).toFixed(2)}%`);
|
|
|
|
// Clear old data
|
|
await persistence.clear();
|
|
```
|
|
|
|
### Batch Operations for Performance
|
|
|
|
Process large datasets efficiently:
|
|
|
|
```javascript
|
|
import init, { VectorDB } from '@ruvector/wasm';
|
|
|
|
await init();
|
|
const db = new VectorDB(384, 'cosine', true);
|
|
|
|
// Batch insert (10x faster than individual inserts)
|
|
const entries = [];
|
|
for (let i = 0; i < 10000; i++) {
|
|
entries.push({
|
|
vector: new Float32Array(384).map(() => Math.random()),
|
|
id: `vec_${i}`,
|
|
metadata: { index: i, batch: Math.floor(i / 100) }
|
|
});
|
|
}
|
|
|
|
const ids = db.insertBatch(entries);
|
|
console.log(`Inserted ${ids.length} vectors in batch`);
|
|
|
|
// Multiple parallel searches
|
|
const queries = Array.from({ length: 100 }, () =>
|
|
new Float32Array(384).map(() => Math.random())
|
|
);
|
|
|
|
const allResults = queries.map(query => db.search(query, 10));
|
|
console.log(`Completed ${allResults.length} searches`);
|
|
```
|
|
|
|
### Memory Management Best Practices
|
|
|
|
```javascript
|
|
import init, { VectorDB } from '@ruvector/wasm';
|
|
|
|
await init();
|
|
|
|
// Reuse Float32Array buffers to reduce GC pressure
|
|
const buffer = new Float32Array(384);
|
|
|
|
// Insert with reused buffer
|
|
for (let i = 0; i < 1000; i++) {
|
|
// Fill buffer with new data
|
|
for (let j = 0; j < 384; j++) {
|
|
buffer[j] = Math.random();
|
|
}
|
|
|
|
db.insert(buffer, `vec_${i}`, { index: i });
|
|
|
|
// Buffer is copied internally, safe to reuse
|
|
}
|
|
|
|
// Check memory usage
|
|
const vectorCount = db.len();
|
|
const isEmpty = db.isEmpty();
|
|
const dimensions = db.dimensions;
|
|
|
|
console.log(`Vectors: ${vectorCount}, Dims: ${dimensions}`);
|
|
|
|
// Clean up when done
|
|
// JavaScript GC will handle WASM memory automatically
|
|
```
|
|

|
|
|
|
## 🐛 Troubleshooting
|
|
|
|
### Common Issues
|
|
|
|
**1. WASM Module Not Loading**
|
|
|
|
```javascript
|
|
// Ensure correct MIME type
|
|
// Add to server config (nginx):
|
|
// types {
|
|
// application/wasm wasm;
|
|
// }
|
|
|
|
// Or use explicit fetch
|
|
const wasmUrl = new URL('./pkg/ruvector_wasm_bg.wasm', import.meta.url);
|
|
await init(await fetch(wasmUrl));
|
|
```
|
|
|
|
**2. CORS Errors**
|
|
|
|
```javascript
|
|
// For local development
|
|
// package.json
|
|
{
|
|
"scripts": {
|
|
"serve": "python3 -m http.server 8080 --bind 127.0.0.1"
|
|
}
|
|
}
|
|
```
|
|
|
|
**3. Memory Issues**
|
|
|
|
```javascript
|
|
// Monitor memory usage
|
|
const stats = db.len();
|
|
const estimatedMemory = stats * dimensions * 4; // bytes
|
|
|
|
if (estimatedMemory > 100_000_000) { // 100MB
|
|
console.warn('High memory usage, consider chunking');
|
|
}
|
|
|
|
// Use batch operations to reduce GC pressure
|
|
const BATCH_SIZE = 1000;
|
|
for (let i = 0; i < entries.length; i += BATCH_SIZE) {
|
|
const batch = entries.slice(i, i + BATCH_SIZE);
|
|
db.insertBatch(batch);
|
|
}
|
|
```
|
|
|
|
**4. Web Worker Issues**
|
|
|
|
```javascript
|
|
// Ensure worker script URL is correct
|
|
const workerUrl = new URL('./worker.js', import.meta.url);
|
|
const worker = new Worker(workerUrl, { type: 'module' });
|
|
|
|
// Handle worker errors
|
|
worker.onerror = (error) => {
|
|
console.error('Worker error:', error);
|
|
};
|
|
```
