Cart Page

This document outlines the functionality and structure required to develop a Cart Page in a web application. The Cart Page allows users to review, modify, and proceed with the items they have added to their shopping cart.

Overview​

The Cart Page serves as a summary of items that users have added to their cart while browsing the application. It enables users to review their selections, adjust quantities, remove items, and proceed to checkout.

Components:​

The Cart Page will consist of the following components:

CartItem Component​

  • Displays individual items added to the cart, including:
    • Product name
    • Image
    • Price
    • Quantity input
    • Subtotal
    • Remove button

CartSummary Component​

  • Provides a summary of the cart, including:
    • Total number of items in the cart
    • Total price
    • Proceed to Checkout button

CartPage Component​

  • Acts as the main container, rendering CartItem and CartSummary components.
  • Manages cart data, updates, and interactions.

Functionality:​

Display Cart Items​

  • Retrieves cart data from the application's state or backend.
  • Renders CartItem components based on the items added to the cart.

Modify Cart Items​

  • Allows users to adjust quantities of items in the cart through quantity input fields in CartItem components.
  • Provides a remove button to delete items from the cart.

Cart Summary​

  • Calculates and displays the total price of items in the cart.
  • Updates the cart summary in real-time based on changes made to cart items (quantity adjustments or item removal).

Checkout Process​

  • Provides a "Proceed to Checkout" button that redirects users to the checkout page or initiates the checkout process.

Testing:​

  • Conducts unit tests for CartItem, CartSummary, and CartPage components.
  • Verifies functionalities like adding/removing items, updating quantities, and calculating the total price.
  • Ensures the "Proceed to Checkout" button functions correctly.

Future Enhancements:​

  • Implement saved carts for users to revisit later.
  • Integrate discount codes or promotions in the cart.
  • Enhance user experience with animations or visual cues for cart interactions.

Conclusion:​

The Cart Page is a crucial component in the shopping experience, providing users with an overview of their selected items and facilitating easy modification before proceeding to checkout.
