WooCommerce — Open-Source E-Commerce for WordPress

Introduction

WooCommerce is the dominant open-source e-commerce plugin for WordPress. By extending WordPress with product management, cart, checkout, and order processing, it turns any WordPress site into a fully functional online store. Its plugin architecture means thousands of extensions are available for payments, shipping, and marketing.

What WooCommerce Does

• Adds a complete storefront, product catalog, and shopping cart to WordPress
• Manages orders, refunds, inventory, and customer accounts
• Integrates with hundreds of payment gateways and shipping carriers
• Supports physical, digital, and subscription-based products
• Provides REST API endpoints for headless and mobile commerce

Architecture Overview

WooCommerce is a WordPress plugin that registers custom post types for products and orders, along with custom database tables for order storage (HPOS). It hooks into WordPress's template hierarchy for storefront rendering and uses action/filter hooks for extensibility. WooCommerce Blocks provide a React-based checkout experience. Background processing uses Action Scheduler for deferred tasks.

• Requires WordPress 6.4+, PHP 8.0+, and MySQL 8.0 or MariaDB 10.4+
• Install from the WordPress plugin directory or via WP-CLI
• Configure tax rates, shipping zones, and payment methods in WooCommerce Settings
• Use a caching plugin and CDN for storefront performance
• Enable High-Performance Order Storage (HPOS) for scalable order management

Key Features

• Block-based checkout and cart for modern, customizable UX
• REST API for headless commerce and mobile app backends
