Headless Retail Commerce
Migrating a legacy enterprise commerce site from monolithic WooCommerce to headless Astro (GRAWC stack) to eliminate checkout crashes and retain SEO rankings.
The client operates a major multi-brand retail e-commerce platform with over 100,000 product SKUs. Their legacy WooCommerce portal suffered from database locks and crashes during black-friday marketing campaigns, directly impacting conversion rates and digital sales.
Eliminate transactional database locks, guarantee sub-300ms checkout times under peak traffic of 50,000 concurrent users, and migrate the frontend without losing valuable search engine visibility built over a decade.
WooCommerce's monolithic nature forced PHP execution and relational queries for every page load. This resulted in SQL database locks whenever thousands of shoppers added items to carts concurrently, while legacy plugin dependencies created heavy performance ceilings.
We decoupled WooCommerce using the GRAWC stack. The WordPress admin was moved behind a private VPN to serve solely as the inventory backend. Astro served as the visitor-facing shop, querying product and tax data via a custom WPGraphQL API endpoint, and deploying to Cloudflare Pages edge hosting.
Lighthouse performance scores reached 100/100. Database locks were completely eliminated as transactions were offloaded to serverless edge checkout routes. Average checkout speed improved by 400%, and search rankings remained identical due to precise RankMath metadata mapping.
By treating the e-commerce database as an offline content API and rendering storefronts statically at the edge, checkout bottlenecks are eliminated at the root.
