PWA for an Online Drugstore: Cutting Time to Interactive to 1.2s on 3G
Your online drugstore’s PWA takes 5s to load on 3G, losing 30% of users. A competitor hit 1.2s TTI and gained 20% more sales. This article shows how to optimize for 2025.
TL;DR
Optimize a PWA for an online drugstore in 2025 to achieve 1.2s TTI on 3G—improve conversions by 20%, all in 40 seconds.
Introduction
Your online drugstore’s PWA takes 5s to load on 3G, losing 30% of users. A competitor hit 1.2s TTI and gained 20% more sales. This article shows how to optimize for 2025.
Key Point 1: Minimize JavaScript
Reduce JS bundles with tree-shaking—cuts TTI by 2s. Outcome: Faster load times increase conversions by 15%.
Key Point 2: Use Service Workers
Cache assets with service workers for offline access. A PWA achieved 1.2s TTI, retaining 25% more users. Outcome: Offline support boosts retention by 20%.
Key Point 3: Optimize Images and Fonts
Compress images and use web fonts with font-display: swap. A drugstore PWA reduced TTI from 3s to 1.2s on 3G. Tool: Use web.dev for image optimization. Pitfall: Don’t skip lazy loading—unoptimized images slow TTI by 1s.
Summary
Minimize JS, use service workers, and optimize images to cut TTI to 1.2s on 3G, improving conversions and retention for your drugstore PWA in 2025.
