Integrations Overview

import { VectoriaDB, DocumentMetadata } from 'vectoriadb';

// 1. Define your metadata interface
interface MyDocument extends DocumentMetadata {
  title: string;
  category: string;
}

// 2. Create a singleton instance
let db: VectoriaDB<MyDocument> | null = null;

export async function getDB() {
  if (db) return db;

  db = new VectoriaDB<MyDocument>({
    // Configuration...
  });

  await db.initialize();
  return db;
}

// 3. Use in your application
export async function search(query: string) {
  const database = await getDB();
  return database.search(query);
}

import { Request, Response, NextFunction } from 'express';
import { VectoriaDB } from 'vectoriadb';

declare global {
  namespace Express {
    interface Request {
      vectoriadb?: VectoriaDB;
    }
  }
}

export function vectoriadbMiddleware(db: VectoriaDB) {
  return (req: Request, res: Response, next: NextFunction) => {
    req.vectoriadb = db;
    next();
  };
}

// Usage
app.use(vectoriadbMiddleware(productIndex));

app.get('/search', async (req, res) => {
  const results = await req.vectoriadb!.search(req.query.q as string);
  res.json(results);
});
