Progressive Web App
Domain: Internet & Web
🎯 Motivation
A web app that works like a native app: offline, push notifications, home screen icon.
📋 Concrete Example
PWA: you visit a website. Browser asks: ‘Add to home screen?’ You accept. Now it has an icon, works offline, and sends push notifications - like a real app. But it is still a website.
🔗 Analogy
A PWA is like a food truck that becomes a restaurant - it starts mobile (website) but can set up a permanent location (home screen), serve customers even when the road is closed (offline), and send promotions (push notifications).
