This Integrated E-commerce System is a comprehensive digital goods and services trading platform designed for the 'Nuxt.js + WordPress' architecture. It unifies diverse product types—including online courses, physical/digital products, and online event tickets—within a single, modern storefront framework, delivering complete end-to-end e-commerce functionality. The system's core features include: a unified Product Hub (for publishing and categorizing courses, products, and events), a smart shopping cart with combined checkout, multiple payment gateway integrations, membership and discount systems, order and fulfillment management, and user review and customer service modules. It leverages WordPress's robust content management capabilities to handle product information, while utilizing Nuxt.js to build a high-performance, server-side rendered (SSR) immersive shopping frontend. This provides users with a seamless browsing, learning, and purchasing experience, and establishes a unified digital revenue hub for businesses.
