# Cart.js

Preferences · [Official website](https://cartjs.org)

Cart.js is an open source JavaScript library that makes it easier to manage the shopping cart in Shopify themes. It wraps the Shopify cart API so that theme developers can add, update and remove items and keep the page in sync without full reloads. As a front-end library it is not a tracking service in itself.
