To give users 🧑💻 flexibility in managing their shopping cart 🛒, implement a feature that allows them to modify the quantity 🔢 of each product in their cart. This feature should also integrate with the commercetools API 🔗 to update the corresponding data 🔄 and recalculate the total cost 💲 accordingly.
- Quantity Modification Interface 🔢🖱️: Include an interface element (like an input box 📥 or spinner 🔄) that allows users to change the quantity of a product in their cart.
- Data Updating 🔄: When a user changes the quantity of a product, the application should make the necessary API call 🔗 to update the cart data in the backend.
- Total Cost Recalculation 💲🔄: After the cart data is updated, recalculate the total cost of the cart and update the total cost displayed to the user.
- Users can modify the quantity of each product in their cart 🛒.
- The application updates the cart data 🔄 using the commercetools API 🔗 when the quantity of a product is modified.
- The application recalculates and displays the updated total cost 💲 when the quantity of a product is modified.
