Progressive Web Apps: Building App-Like Web Experiences

Progressive Web Apps (PWAs) bridge the gap between web and native apps. They're fast, reliable, and engaging.

Service Workers

Service Workers are scripts that run in the background, enabling offline functionality.

// Register a Service Worker
navigator.serviceWorker.register('/sw.js');

Offline First

Cache assets and API responses to enable offline functionality.

Web App Manifest

Define app metadata in manifest.json for homescreen installation.

{
  "name": "My App",
  "short_name": "MyApp",
  "start_url": "/",
  "display": "standalone",
  "background_color": "#ffffff",
  "theme_color": "#000000"
}

Push Notifications

Engage users with push notifications even when they're not using your app.

App Shell Architecture

Separate app shell from dynamic content for faster loads and offline support.

Installation Prompts

Users can install PWAs on their home screen like native apps.

Performance

PWAs are fast. Service Workers enable near-instant loads after first visit.

Cross-Platform

One codebase works on web, iOS, Android, and desktop. No need for separate native apps.

PWAs represent the future of web applications. They offer native app capabilities without the distribution friction of app stores.
