Applying ISR, streaming SSR, and advanced image optimization in Next.js to achieve sub-1.2s LCP on a product catalog with 500+ SKUs.
Srimaccafes needed a storefront that felt instant, even on 3G connections in Tamil Nadu. The benchmark was a Largest Contentful Paint (LCP) under 1.2 seconds for the product listing page.
Product listing pages are pre-rendered at build time and served as static HTML from the CDN edge. ISR with a 60-second revalidation window ensures prices and stock levels stay fresh without sacrificing speed.
