Progressive Web Apps: Bridge Between Web and Mobile

Progressive Web Apps combine web accessibility with native app functionality, offering push notifications, offline capability, and home screen installation. PWA adoption increases engagement—Twitter's PWA sees 65% more pages per session and 75% more tweets sent. Core technologies include Service Workers for offline functionality, Web App Manifest for installation prompts, and HTTPS requirement for security. Key features include responsive design across devices, app-like navigation patterns, push notification support, and offline content availability. Performance benefits include faster loading through caching strategies, reduced data usage, and improved Core Web Vitals scores. Implementation involves service worker registration, cache strategy definition, and offline fallback pages. User engagement improves through native app behaviors like splash screens, full-screen mode, and OS-level integration. Tools like Workbox simplify service worker development, while Lighthouse PWA audits validate implementation quality. Business benefits include reduced development costs versus native apps and broader device compatibility.
