Why You Should Choose PWA

Direct answer

What is a Progressive Web App and why build your website or store using PWA methodology — performance, UX, and business benefits.

Many of our clients choose websites built as Progressive Web Apps. The PWA approach doesn't mean writing a site from scratch — it's about increasing performance through a specific methodology. PWAs typically load in 2-3 seconds, have lower bounce rates, and engage users more effectively.

A Progressive Web App combines the best features of websites (accessibility, indexability, easy updates) with capabilities previously reserved for native mobile apps (offline support, push notifications, home screen installation). It is not a new framework — it is a set of patterns and technologies that can be applied to an existing site.

PWA vs Native vs Hybrid — Data-Driven Comparison

Choosing between PWA, a native app, and a hybrid solution is a critical architectural decision. Each approach has strengths and limitations, but implementation data clearly shows when PWA is the best choice.

Durable gains come from coupling optimization with release governance. Without ongoing regression discipline, previously recovered performance is often eroded by subsequent campaign scripts, layout changes, or feature additions.

PWA Requirements

• Google Lighthouse score of at least 75% in the PWA category
• Proper meta entries in the head section (theme-color, viewport)
• JavaScript file with Service Worker logic
• PWA Manifest (app information, icons, display mode)
• Responsive page designed mobile-first
• SSL certificate (HTTPS required for Service Workers)

Service Worker Lifecycle

The Service Worker is the heart of a PWA — a JavaScript script running in the background, independent of the page. It intercepts network requests, manages cache, and enables offline functionality. Understanding its lifecycle is critical for proper implementation.

Caching Strategies

The choice of caching strategy determines offline behavior and loading speed. There is no single ideal strategy — different resources require different approaches. The key is balancing data freshness with access speed.

Main Caching Strategies

• Cache First — cache first, network as fallback (ideal for static assets: images, fonts, CSS)
• Network First — network first, cache as fallback (ideal for API data, dynamic content)
• Stale While Revalidate — serve from cache immediately, update in background (balance of speed and freshness)
• Cache Only — exclusively from cache (pre-cached assets, app shell)
• Network Only — exclusively from network (forms, transactions, sensitive data)

In practice, most PWAs use a combination of strategies. The app shell (navigation, layout, icons) is served Cache First, dynamic content via Network First, and frequently accessed data (product catalog) via Stale While Revalidate.
