Building the Online Store

Components Needed

1. Navigation Bar: For routing between different pages (Shop and Cart).
2. Cart: To view selected items.
3. Product List: Where products can be displayed and selected.

Implementation Steps

• Define routes using React Router for component navigation.
• Use state management, including custom hooks and context API for managing the shopping cart.

Custom Hooks

• Create custom hooks (useCart) to manage the shopping cart state.
• Share the cart state across components via context API.

Error Handling and Validation

• Implement error handling within forms using structure validation (with Yup or similar) for cleaner data input management.

Deployment

• Use built commands (npm run build) to prepare the app for production.
• Deploy to a server (use services like Heroku, Vercel, or any web host).

Conclusion

• Complete walkthrough of building a simple e-commerce application using React.
• Encouragement to ask questions and seek help regarding any difficulties encountered.

Key Takeaways 🚀

• React is a powerful library that allows for efficient UI building.
