PWA Plugin

🚀 Overview

The PWA Plugin – Progressive Web App Add-on is designed to bridge the gap between web and native apps by enabling your website to behave like an app on mobile and desktop devices. It adds service workers, offline caching, push notifications, install prompts and app-shell navigation — without needing a full mobile rebuild.

Real-world use: Perfect for blogs, e-commerce sites, membership portals, SaaS platforms or any web property that wants improved engagement, faster load times and offline/instantly installable access.
Target users: WordPress site owners, developers converting websites to “app-like” experiences, agencies building high-engagement web platforms.

✨ Key Features

• Service Worker Caching: Automatically installs service worker to cache assets, pages and API responses for offline & fast access.
• Install Prompt: Website becomes “Installable” on supported browsers/OS-homescreen with native-app like behaviour.
• Offline Mode: Users can access previously visited pages or cached content when offline or on slow connections.
• Web Push Notifications: Send push alerts via Firebase/OneSignal to users even when not on site—boost retention.
• Home-Screen Icons & Splash Screen: Automatically generates app icons, splash screen for multiple devices/sizes and manifests.
• Responsive & App Layouts: Support for “mobile-app style” navigation bars, swipe gestures, offline fallbacks to keep UI smooth.
• Background Sync & Updates: Option to sync data/background-update when connections restore.
• SEO-Friendly: Retains indexable content, server-rendered pages, and improves page-load performance—benefiting search ranking.
• Customizable Branding: Configure theme colours, icon sets, splash screen text and offline placeholder pages.
• Compatibility: Works with WordPress (plugin), or generic PHP frameworks where you can hook into service-worker registration and manifest.

⚙️ Technical Stack

• Language: PHP (for plugin backend) + JavaScript (service-worker, client-side caching).
• Frontend: HTML5 / CSS3, responsive layouts, modern browser APIs.
• Web APIs: Service Workers, Web Push Notifications API, Cache API, App Manifest, Background Sync.
• Server Requirements: PHP 7.4+ or 8.x, HTTPS (required for service workers & push), mod_rewrite (if WordPress).
• Dependencies: Firebase/OneSignal for Push (optional), Workbox (optional) for advanced caching strategies, Web-manifest JSON.

🧩 Installation Guide

1. Upload & Activate: If WordPress: install plugin via Plugins → Add New → Upload ZIP, then Activate. If generic PHP: place plugin folder, include bootstrap code.
2. Configure Settings: Navigate to plugin settings: set site name, icons, theme colour, splash screen design, offline page template.
3. Push Notifications: If using web push: enter Firebase/OneSignal keys, set subscription prompts and notification templates.
4. Service Worker Setup: Choose caching strategies: “Cache first” for assets, “Network first with fallback” for pages. Save and register.
5. Test Install Behaviour: On supported browsers (Chrome, Edge, Safari on iOS): confirm that “Add to home screen” appears, icon & splash show, offline navigation works.
6. Go Live: Ensure HTTPS, clear caches, monitor service-worker network behaviour in DevTools, verify push subscriptions.

Tip: Use Lighthouse tool to measure “Installable” PWA checks, ensure service worker version increments on update to avoid stale caches.
