Jamstack Storefront

Overview

A Jamstack storefront pre-renders catalog pages at build time for maximum performance and CDN cacheability, while using client-side JavaScript and commerce APIs for dynamic functionality (cart, checkout, account). Next.js with Incremental Static Regeneration (ISR) and Astro with on-demand rendering are the two dominant approaches, each offering different tradeoffs between build times, freshness, and interactivity. This skill covers setting up a Jamstack commerce site, managing catalog regeneration, and integrating headless commerce APIs.

When to Use This Skill

• When SEO and Core Web Vitals scores are top priorities — static HTML scores near-perfect Lighthouse results
• When you have a large catalog that rarely changes and want sub-100ms page loads from CDN
• When you want to decouple the commerce backend (Shopify, Saleor, commercetools) from the storefront deployment cycle
• When your team wants to use modern React/Astro tooling rather than a platform's proprietary theme system
• When you need to combine commerce data with a CMS (Contentful, Sanity) at build time

Prerequisites & Platform Notes

This skill is written for custom/headless storefronts (Node.js, Python, or similar backend). The code examples use TypeScript/Node.js and can be adapted to any stack.
