E-commerce Landing Page with Shopping Cart in Vue.js

I'll create a complete e-commerce landing page with a shopping cart using Vue.js Single-File Component (SFC) format 12. This implementation includes a responsive design with product listings and a functional shopping cart.

Features

This e-commerce landing page includes:

1. Responsive Layout - Works on mobile, tablet, and desktop devices
2. Product Catalog - Displays products with images, names, and prices
3. Category Filtering - Filter products by category
4. Shopping Cart - Add, remove, and update quantities of products
5. Cart Summary - Shows total items and cost

Implementation Details

• The page uses Vue.js 3 with the Composition API and <script setup> syntax 3
• The shopping cart is implemented as a sliding sidebar
• Product data is stored in a reactive array that could be replaced with API calls
• State management is handled through Vue's reactivity system with refs and computed properties

To use this in your project, you can copy this Single-File Component into your Vue.js application. If you're starting from scratch, you can create a new Vue project using the Vue CLI or Vite as described in the Vue.js documentation 3.
