Description: After we did the persistent cart we got an error on the build process. It was previous fixed but after this the build process was successful but the persistent cart stopped working. Every time after the user refreshes the page all objects inside the LocalStorage become empty.

Context: These changes will ensure that the persistence cart will work on build process and on production and product will be deleted from LocalStorage when user removes it from cart.

Changes: 1: Create a LOCAL_STORAGE_KEY to make it easy to change or maintain in the future. 2: Pass the LocalStorage as String to ensure that it is the behavior. 3: Verify typeof window !== "undefined" if so, ".getItem()" to or ".setItem()" from LocalStorage. 4: Verify if "products.length" equal 0 if so, thats mean user removed some products from the cart and need to remove it from LocalStorage also.

Cheers! 🍺
