Add a Quantity Input to the Cart Page to Add or Remove Items from a Shopping Cart in Next
Updating the quantity of a product is an essential feature for a great checkout experience. In this lesson, we will create a feature to update the quantity of each product in our cart.
We'll create a new component with a form input to increment the number of items and a button to submit that form. Additonally, we will create an updated item function in the useCart hook that adds the ability to update the quantity of a product in the shopping cart by ID and trigger an update whenever the quantity form on the cart table is submitted.

You can use that session ID and the Stripe API to look up the order and display details on the "receipt" or order confirmation page. You additionally would likely want to clear the cart state as at that point, the items would have been purchased.
If a cart item is updated to '0', how do you remove that row from the table dynamically?
This is what I did in the useCart.js file:
// Update number of items in cart function updateItem({id, quantity}) { updateCart((prev) => { let cart = {...prev}
if (cart.products[id]) {
cart.products[id].quantity = quantity
} else {
cart.products[id] = {
id,
quantity: 1,
}
}
if (cart.products[id].quantity === 0) {
delete cart.products[id]
}
return cart
})}
