Functionality to be added

The app must have the following functionalities

• When an unauthenticated user tries to access the Cart Route, then the page should be navigated to Login Route

• Following are the features to be implemented

  • Feature 1

    • When an authenticated user tries to add the same product multiple times
      • The quantity of the product should be updated accordingly, and the count of the cart items in the header should be remained same

  • Feature 2

    • The total amount and number of items in the cart should be displayed in the Cart Route

  • Feature 3

    • In each cart item in the cart
      • When the plus icon is clicked, then the quantity of the product should be incremented by one
      • When the minus icon is clicked, then the quantity of the product should be decremented by one
      • When the quantity of the product is one and the minus icon is clicked, then the respective product should be removed from the cart
      • Based on the quantity of the product, the product price and the Cart Summary, i.e the total cost should be updated accordingly

  • Feature 4

    • When an authenticated user clicks on the remove button, cart item should be removed from the cart list

  • Feature 5

    • When an authenticated user clicks on the Remove All button, all the cart items should be removed from the cart and Empty Cart View should be displayed

• The CartContext has an object as a value with the following properties

  • cartList - this key stores the cart items
  • removeAllCartItems - this method is used to remove all the cart items in the cartList
  • addCartItem - this method adds the cart item to the cartList
  • removeCartItem - this method removes the cart item from the cartList
  • incrementCartItemQuantity - this method increases the quantity of a product in the cartList
  • decrementCartItemQuantity - this method decreases the quantity of a product in the cartList

Components Structure

Use these files to complete the implementation:

• src/App.js
• src/components/Cart/index.js
• src/components/Cart/index.css
• src/components/CartItem/index.js

• The line-height CSS property sets the height of a line box. It's commonly used to set the distance between lines of text

  line-height: 1.5;
  

  
  

• The array method find() returns the first item's value that satisfies the provided testing function. If no item is found, it returns undefined

Things to Keep in Mind

• All components you implement should go in the src/components directory.
• Don't change the component folder names as those are the files being imported into the tests.
• Do not remove the pre-filled code
