Store structure

[tejas-hosamani]

• Removed quantity selector from the single product page

  • Why: Once the user adds an item to the cart, we shouldn't show the Add to cart button, if we keep it, then there's a case of what to do if and when the user clicks on that button again
    1. Do nothing, ignore the press - then it's redundant to keep the button - some users may think the site is not working etc
    2. Maybe we could choose to increase quantity, but that wouldn't be intuitive behaviour of the Add to cart button
    3. Change the button to indicate this product has been added to the cart already ✅
  • With that, if we have a quantity selector, once the user adds that item to the cart, the quantity selector would be redundant.

• Different sizes of the same product are considered as different product in the cart so that they can buy multiple items of different sizes

• Code refactor

• Removed fake loader for better UX
