01 / Executive Overview
Setting
the Stage
"Ultra-fast headless commerce solution engineered for high-traffic drop sales and instant checkout state persistence."
ShopWave Global required a next-generation storefront capable of surviving flash sales where 100,000+ shoppers land concurrently. ProjonmoLab architected a headless Next.js PWA powered by Vercel Edge Networks, GraphQL API aggregation, and Stripe 1-tap express checkout.
02 / The Challenge
Slow Legacy Monolithic Storefront & Flash Sale Crashes
The brand's previous Shopify Plus setup experienced heavy server-side rendering slowdowns during product drops, resulting in lost revenue and customer frustration. The 9-step checkout flow lost over 45% of users before payment confirmation.
Key Bottlenecks
- 1Storefront page load times exceeding 4.8 seconds on mobile networks.
- 2Database timeouts during high-volume cart reservations.
- 3Cluttered multi-page checkout process requiring redundant address entries.
03 / Solution
Edge-Rendered PWA & Optimistic Cart State Engine
We decoupled the storefront using Next.js App Router with Incremental Static Regeneration (ISR) and Edge Middleware. Cart state is managed optimistically on the client using IndexedDB and synced asynchronously via GraphQL.
01
Edge HTML Caching with ISR
Product pages served instantly from the nearest CDN edge node.
02
3-Click Express Checkout
Integrated Apple Pay, Google Pay, and Shop Pay for frictionless 1-tap purchases.
