I want to refactor and clean the code of the company website cart page.
The cart page is composed of a products list and a summary. Heres the list of the business logics implemented:
- If there are no products then display "No Products..."
- If there are products then display products table and price summary
The products table display the cart products list of the user.
User Actions
- User can delete product of the products list
When a user delete a product it delete all quantities of the concerned product
Product Row
There are 3 different type of products.
Each row contains :
- A picture
- The product name
- The quantity
- The total price
- A button to delete the product
An common product is displayed without specific rules
An new product is displayed with a label 'New product' instead of the picture and next to the product title
An ended product is displayed with a label 'End soon' next to the picture and the product title
The summary display
- Total price of the cart
- Delivery fees
- Total amount to pay.
Total price
Calculate all the cart's products price multiplicated by their quantities
Delivery fees
- If user should pay fees then add delivery fees ($3.99) to total price
- If user should not pay fees then add nothing to the total price
Total amount to pay
Amount to pay = total price + delivery fees
- Clean the code
- do NOT break any business rules.
yarn start: Launch the page
