E-commerce skills are valuable because every online store needs product catalogs, filters, and shopping carts. This project teaches you how to handle large amounts of data efficiently.
You'll learn pagination, which is crucial when you have thousands of products. Loading everything at once would be too slow. You'll also learn filtering and searching, which users expect in modern web apps.
State management with shopping carts teaches you how to handle complex application state. The cart needs to persist even if users refresh the page, which is a common real-world requirement.

Build a full-stack product browsing system with advanced filtering, sorting, pagination, and shopping cart functionality. This project teaches you how to handle complex state management, build intuitive user interfaces, and optimize database queries for better performance.
You'll create both the backend API for product management and a polished frontend that provides smooth browsing and shopping experience similar to real e-commerce sites.
Implement complex filtering and search logic
Build efficient pagination for large datasets
Manage shopping cart state with Redux Toolkit or Context API
Optimize database queries with indexes and projections
Create responsive product grid layouts
Handle loading states and error boundaries
Product catalog API with filtering, sorting, and pagination
Product search by name and description (case-insensitive)
Filter products by category, price range, and rating
Sort products by price, rating, name, or newest first
Shopping cart stored in browser local storage
Add, remove, and update quantities in cart
Display cart total and item count
Responsive product grid (1 column mobile, 2-3 tablet, 4 desktop)
Product detail page with full information
id, name, description, price, category, imageUrl
rating (1-5 stars), reviewCount, stock, sku
brand, tags (array), createdAt, updatedAt
Create seed data for at least 50 products across 5 categories
GET /api/products - Get paginated products with filters
GET /api/products/:id - Get single product details
GET /api/categories - Get all available categories
GET /api/products/search - Search products by keyword
Query parameters: page, limit, category, minPrice, maxPrice, minRating, sort
Product listing page with filter sidebar and product grid
Active filters display with ability to clear individual filters
Search bar with debounced search (300ms delay)
Pagination controls (previous, next, page numbers)
Loading skeletons while fetching products
Empty state when no products match filters
Shopping cart icon with item count badge in header
Cart sidebar or modal showing all items and total
Product cards showing image, name, price, rating
Build reusable filter component that updates URL query params
Implement debounced search to reduce API calls
Synchronize cart state with local storage
Handle loading and error states gracefully
Build efficient MongoDB queries with multiple filters
Add indexes to frequently queried fields (category, price, rating)
Implement optimistic UI updates for cart operations
Preserve scroll position when navigating back from product page
Products: fetched from API, stored in component state or Redux
Filters: synced with URL query parameters
Cart: persisted in local storage, managed with Context API or RTK
UI state: loading, errors, selected product, cart open/closed
Add product image carousel on detail page
Implement "Recently Viewed" products feature
Add product comparison (select 2-3 products to compare)
Show related products on detail page
Add wishlist/favorites functionality
Implement infinite scroll instead of pagination
Add price alerts (notify when price drops)
Show stock levels and low stock warnings
MongoDB Queries: Look up MongoDB query operators like $gte, $lte, $regex. These help you filter data.
Pagination: Search for "pagination tutorial" or "API pagination best practices".
React Context API: React docs have a great Context tutorial. Use it for cart state management.
Redux Toolkit: If you prefer Redux, check out Redux Toolkit docs. It's simpler than old Redux.
Local Storage: MDN docs on localStorage. It's simple - just setItem() and getItem().
Debouncing: Search for "JavaScript debounce" to learn how to delay search requests.

All filters work correctly and can be combined
Search returns relevant results quickly
Pagination works smoothly with correct page counts
Cart persists across browser refreshes
UI responds immediately to user actions
Loading states are clear but not intrusive
Application works well on mobile devices
Database queries execute in under 500ms with 1000+ products
Study MongoDB query operators (and, or, gte, lte, regex)
Learn about database indexing for performance
Research debouncing patterns in React
Explore URL state management with React Router
Look into skeleton loading patterns
Hint: Store your filter state in URL query parameters so users can bookmark or share filtered views. This also makes browser back/forward buttons work naturally.
For the cart, create a custom hook like useCart() that handles all cart operations and local storage synchronization. This keeps your components clean and makes the cart logic reusable.
