The Power of Progressive Web Apps (PWAs)

Progressive Web Apps represent the convergence of web and mobile app capabilities, offering users app-like experiences through the browser.

What Makes a PWA?

PWAs are characterized by:

• **Progressive**: Work for every user regardless of browser choice
• **Responsive**: Fit any form factor—desktop, mobile, tablet
• **Connectivity Independent**: Work offline or on low-quality networks
• **App-like**: Feel like a native app with app-style interactions
• **Fresh**: Always up-to-date thanks to service worker update process
• **Installable**: Can be added to home screen without app store

Core Technologies

1. **Service Workers**: Enable offline functionality and background sync
2. **Web App Manifest**: Defines how the app appears when installed
3. **HTTPS**: Required for security and service worker functionality

Building a PWA

• Implement a responsive design
