Architecture Overview

What WooCommerce Blocks Are

React-based blocks for the WordPress block editor (Gutenberg):

• Cart Block — replaces [woocommerce_cart] shortcode
• Checkout Block — replaces [woocommerce_checkout] shortcode (default since WC 8.3)
• Product Blocks — grids, filters, search, featured products
• Mini Cart Block — header cart widget
