E-Commerce App Dev – Cart Redux Config (React Native, Redux Toolkit, TypeScript, State Management)

🔥 In Part 26 of our E-Commerce Hybrid App Development series, we set up the Redux logic for the cart system. This is the backbone of managing cart items, quantities, and totals across the app. With Redux Toolkit, we ensure scalable and maintainable state management from product to checkout.

📌 What you’ll learn in this video:
✅ Setting up a cart slice using Redux Toolkit
✅ Defining actions – addToCart, removeFromCart, updateQty
✅ Structuring the cart state (items, total, quantity, etc.)
✅ Connecting cart logic to the UI and components
✅ Dispatching actions from product and cart screens
✅ Using selectors to access and compute cart state
✅ Handling duplicate item logic and quantity merging
✅ Persisting cart state across sessions (optional)

💡 Why Cart Redux Config Matters:
▶️ Ensures consistent cart behavior across the entire app
▶️ Centralizes logic, making it easier to manage and debug
▶️ Supports future features like coupon codes, inventory check, and checkout flow
▶️ Provides a scalable foundation for any commerce app
▶️ Follows modern best practices with Redux Toolkit
