How to Build an E-Commerce Store with AI (No Code Required)

What We're Building

By the end of this tutorial you'll have a working e-commerce store with:

• Product catalog with images, prices, and descriptions
• Shopping cart with quantity controls and running total
• Stripe checkout for real payment processing
• Order history so customers can track past purchases
• Search, filters, and categories for product discovery
• PWA support so the store works on mobile like a native app

Total time: about 15 minutes from blank canvas to deployed store.

Step 1: Write the Right Prompt

The quality of your store depends on the prompt. Be specific about products, layout, and features — GenMB uses every detail to generate better code.

Here's the exact prompt we'll use:

Build an e-commerce store for a small coffee roastery called "Ember Roasters." The store sells 8 specialty coffee products (whole bean and ground) ranging from $14 to $28. Include a hero section with a tagline "Small-batch roasted, delivered fresh," a product grid with images, prices, and an Add to Cart button on each card. Add a sticky shopping cart sidebar that shows selected items, quantities, and a subtotal. Include a checkout page with a Stripe payment form. After purchase, show an order confirmation with an order number. Add an Order History page where returning customers can see past orders. Use a warm color palette — dark brown, cream, and amber accents. Use React with TypeScript.

Paste this into GenMB and click Generate. Within about 30 seconds, Code Healer validates the output and fixes any runtime errors automatically.

Step 2: Add Stripe for Payments

GenMB's plugin system connects Stripe without writing integration code.

1. Open your generated app in the editor.
2. Click the Integrations tab in the left sidebar.
3. Search for Stripe and enable the plugin.
4. Enter your Stripe Publishable Key and Secret Key (use test keys during development — they start with pk_test_ and sk_test_).
5. Click Save and regenerate.

GenMB injects the Stripe SDK, creates the checkout session endpoint, and wires up the payment form. You'll see the Stripe card element appear on the checkout page.

Tip: Use Stripe's test card number 4242 4242 4242 4242 with any future expiry date to simulate successful payments.

Step 3: Add Supabase for Product Database and Orders

Static product data works for a demo, but a real store needs a database for inventory updates and order records.

1. Go to the Integrations tab again.
2. Enable the Supabase plugin.
3. Enter your Supabase Project URL and anon key.
4. Click Save and regenerate.

GenMB scaffolds two tables:

After regeneration, your product catalog reads from Supabase and orders are persisted on successful checkout.

Step 4: Enable PWA for Mobile Shopping

More than half of online shopping happens on mobile. Turning your store into a Progressive Web App takes one click.

1. Open the Settings panel in the editor.
2. Toggle PWA Mode on.
3. Regenerate.

GenMB adds a service worker, a web app manifest, and offline caching. Customers can add your store to their home screen and browse products even on spotty connections.

Step 5: Deploy with a Custom Domain

1. Click the Deploy button in the top-right corner.
2. Your store goes live at your-app.genmb.com within seconds.
3. To use your own domain (e.g., shop.emberroasters.com), open Deploy Settings and enter your custom domain.
4. Add the CNAME record GenMB provides to your DNS settings.
5. SSL is provisioned automatically.

Your store is now live with HTTPS, CDN caching, and a custom domain.

Step 6: Iterate — Add Search, Filters, and Categories

Your store works, but customers need to find products fast. Use GenMB's chat refinement to add discovery features without rebuilding.

Add search: Type in the chat panel:

Add a search bar above the product grid that filters products by name and description in real time.

Add category filters: Follow up with:

Add category filter buttons (All, Light Roast, Medium Roast, Dark Roast, Decaf) above the product grid. Clicking a category shows only matching products. The active category button should be visually highlighted.

Add price sorting: Then:

Add a sort dropdown next to the search bar with options: Featured, Price Low to High, Price High to Low.

Each refinement takes a few seconds. Code Healer validates the changes automatically.

What You've Built

In about 15 minutes you've gone from a text prompt to a deployed e-commerce store with:

• Product catalog powered by Supabase
• Shopping cart with quantity management
• Stripe checkout with real payment processing
• Order history for returning customers
• Search, category filters, and price sorting
• PWA support for mobile shoppers
• Custom domain with SSL

No frameworks to learn. No hosting to configure. No payment integration docs to read.
