This document discusses using Gatsby, WordPress, and WooCommerce for building blazing fast ecommerce sites. It highlights that Gatsby is fast, secure, free, and has great developer tools and content delivery. WooCommerce is a popular ecommerce platform that allows full store control. WPGraphQL integrates WordPress and Gatsby by exposing WordPress data through GraphQL. A case study demonstrates using these technologies together with additional plugins for features like events and Stripe payments. Lessons learned are that WordPress plugins may not all work and content is not immediately available, but Gatsby enables offline support and progressive web apps.
