Audiophile Ecommerce is a React-based e-commerce storefront solution built with Next.js for the Frontend Mentor Audiophile challenge, demonstrating the full shopping flow from product browsing to order confirmation.
What is Audiophile Ecommerce?
This solution implements the Audiophile e-commerce website challenge from Frontend Mentor, created by developer Lucas Winkler. It takes a static design and turns it into a working storefront with a product catalog, cart, and checkout experience. The project runs on Next.js and uses TailwindCSS for styling, with zod and react-hook-form powering checkout validation.
Key Features
- Add/Remove products from cart — Users can add and remove audio products from the cart throughout the storefront.
- Edit product quantities — Cart quantities can be increased or decreased before checkout.
- Checkout validation — All checkout fields are validated with zod and react-hook-form, showing errors if fields are missed or incorrect.
- Correct order totals — Shipping always adds $50, and VAT is calculated as 20% of the product total excluding shipping.
- Order confirmation modal — After checkout, a modal displays the order summary.
- LocalStorage cart persistence — The cart state is stored in the browser via LocalStorage, so it survives page refreshes.
- Responsive layout — Built mobile-first with semantic HTML5, Flexbox, and Grid for optimal viewing on any screen size.

How does Audiophile Ecommerce work?
Users browse the storefront, add products to the cart, edit quantities, and proceed to checkout. Checkout requires filling in all fields with validation; submitting shows an order confirmation modal with the calculated totals. The cart is saved to LocalStorage so state persists across refreshes.
