Comprehensive example showing how to load and use all SQLite extensions together.

node example.js

Features:

• Load all four extensions (vector, sync, js, ai)
• Automatic version detection
• Example 1: Vector search with embeddings and quantization
• Example 2: Database synchronization with CloudSync
• Example 3: JavaScript user-defined functions (slugify, factorial, eval)
• Example 4: AI inference setup instructions
• Example 5: Combining extensions for powerful workflows
• Graceful handling of missing extensions

const { getExtensionPath } = require('@sqliteai/sqlite-vector'); // or @sqliteai/sqlite-sync @sqliteai/sqlite-js @sqliteai/sqlite-ai
const Database = require('better-sqlite3');

const db = new Database(':memory:');
db.loadExtension(getExtensionPath());

// Get the extension version
db.prepare("SELECT vector_version()").pluck().get(); // or cloudsync_version() js_version() ai_version()
