This is the API server, not the website

This NestJS API is listening on port 5172 (JSON under /api/...). The React storefront runs on port 5173.

Open the site here:
http://127.0.0.1:5173 or http://localhost:5173

If that says connection refused, start Vite in another terminal:

cd frontend
npm install
npm run dev

Or from the repo root: npm install then npm run dev (starts API + Vite).
