Cart.js

Cart.js is a lightweight JavaScript library specifically designed for working with Shopify's Ajax Cart API, making it easier to build dynamic shopping cart experiences. It provides a simple, jQuery-like interface for common cart operations like adding products, updating quantities, and retrieving cart data without page reloads. The library handles the complexity of Shopify's cart API, offering data binding and automatic DOM updates when cart contents change. Cart.js enables developers to create Ajax-powered "add to cart" buttons, slide-out cart drawers, and dynamic cart update functionality. It includes features for formatting currency, handling variant selections, and managing cart attributes. The library is designed to work alongside Shopify themes, enhancing the default cart functionality with modern, interactive experiences. Cart.js simplifies the process of creating seamless shopping experiences that don't require full page refreshes.
