Build guide

1. 01Project Scaffolding & Database Schema

   Initialize the Next.js project with Tailwind CSS and configure the Neon Postgres database schema for multi-tenant merchants, products, categories, orders, and cart sessions.

   Scaffold a new Next.js full-stack application using App Router and TypeScript. Install Tailwind CSS and Drizzle ORM configured to connect to a Neon PostgreSQL database. Create database migrations and schema models for: (1) merchants (id, storeName, email, currency, createdAt), (2) products (id, merchantId, title, description, price, inventoryCount, images), (3) categories, (4) orders (id, merchantId, customerEmail, totalAmount, status, itemsJson), and (5) cartSessions. Ensure foreign key constraints and indexes are optimized for multi-tenant isolation by merchantId. Include sample seed data for testing.

2. 02Merchant Dashboard & Product Management

   Build the authenticated merchant admin dashboard to manage product inventory, categories, pricing, and view store orders.

   Build an authenticated merchant dashboard in Next.js using better-auth for multi-tenant user sign-in. Create server actions and UI pages for managing products (CRUD operations, inventory stock updates, pricing, and image upload placeholders). Build an orders management view showing incoming customer purchases with filtering by fulfillment status. Ensure all database queries strictly scope data retrieval to the currently authenticated merchant ID.

3. 03Embeddable Storefront JavaScript Widget

   Develop a lightweight, bundled JavaScript script that external website owners can paste into their HTML to render a fully functional shopping cart and product grid widget.

   Build a production-ready embeddable JavaScript widget bundle (using a separate entry point or standalone build output) that third-party websites can inject via a script tag like `<script src='https://yourdomain.com/embed.js' data-store-id='merchant_uuid'></script>`. The script should dynamically create a Shadow DOM container on the host page to prevent CSS style bleeding, fetch the merchant's product catalog from your backend API, render a responsive product grid, and handle adding items to a local persistent shopping cart state stored in localStorage.

4. 04Checkout Flow & Stripe Integration

   Implement a secure checkout modal inside the embeddable widget that processes payments via Stripe Checkout sessions.

   Extend the embeddable widget shopping cart to include a checkout drawer. When the customer clicks checkout, call a backend Next.js API route that generates a secure Stripe Checkout session (or payment intent) passing the merchant's connected Stripe account metadata and order line items. Handle webhook callbacks from Stripe to update order status in the database to 'paid', decrement product inventory counts, and trigger an automated receipt email via Resend.

5. 05Standalone 'Instant Site' Builder

   Create a simple hosted web page builder allowing merchants without an existing website to publish a standalone landing page featuring their embedded store catalog.

   Build a 'Instant Site' generator feature in the Next.js dashboard. Allow merchants to customize a standalone storefront page by choosing a banner image, headline, accent color, and layout style. Create a dynamic route (`/store/[storeHandle]`) that renders a clean, hosted public storefront page embedding their product catalog and cart widget, complete with SEO meta tags and responsive mobile styling.
