Saevix Software Agency — CivilPoint — Stationery E-Commerce
Eliminated shop page waterfall and boosted load speeds by 60%
The Problem
CivilPoint's stationery storefront suffered from severe cumulative layout shifts (CLS) and a massive rendering waterfall on their primary shop page. Because the legacy codebase relied heavily on client-side fetching inside useEffect hooks, users stared at loading spinners for up to 3 seconds while the browser chained API requests to render the product grid.
The Approach
To resolve the client-side fetching waterfall in Next.js, we aggressively refactored the shop page to utilize React Server Components (RSC). We moved all initial data fetching to the server edge, streaming the HTML directly to the client. For highly interactive elements (like the cart sidebar and real-time variant selectors), we isolated the state into narrow 'use client' boundary components powered by Zustand. We consciously rejected heavy state management like Redux in favor of Zustand to keep the client bundle size under 60kb.
The Result
This Next.js e-commerce performance optimization eliminated the waterfall entirely. The shop page Time to Interactive (TTI) dropped from 3.2s to 1.1s, and we achieved a perfect 0.0 CLS score. The 60% faster load speed correlated directly with a 25% drop in cart abandonment rates over the following month.
Lessons
Initially, we tried to stream too many granular Suspense boundaries, which actually degraded perceived performance due to flickering skeleton loaders. We learned that grouping server fetches into a single, higher-level Suspense boundary provided a much smoother, cohesive loading experience for e-commerce grids.
