Offline Mode: PWAs can cache resources locally, enabling offline mode and faster load times.
Engaging UX: PWAs can provide immersive full-screen experiences, complete with animations and interactions similar to native mobile apps.
Easy Installation: Users can easily install PWAs on their home screen, without needing to go through the app store.
Cross-platform compatibility: PWAs can run on any platform that supports modern web technologies, including desktop browsers, Android, iOS, and Chrome OS.
Purpose of PWAs:
The primary goal of PWAs is to provide a seamless and engaging user experience that combines the benefits of web and native mobile applications. By offering fast load times, offline mode, and full-screen experiences, PWAs aim to bridge the gap between traditional web pages and native mobile apps.
Features of PWAs:
Responsive Design: PWAs are responsive and adapt to various screen sizes and orientations.
Service Workers: PWAs use service workers to enable background sync, push notifications, and offline capabilities.
HTTPS Requirement: PWAs require secure communication over HTTPS protocol to protect user data.
Manifest File: PWAs use manifest files to declare metadata about the app, such as iconography, colors, and splash screens.

Usage of PWAs:
PWAs can be used in a variety of scenarios, including e-commerce, news sites, social media platforms, productivity tools, and gaming. They are particularly well suited for businesses looking to engage customers on mobile devices, without requiring them to download and install a native app.
