Introduction
In layman's terms, Progressive Web Application (PWA) is a type of application software that is easily installable directly via the web browser, that offers a native-like app experience to end users regardless of device variants.
PWA promises many key capabilities as compared to regular web applications, such as:
- Works in any network conditions, including offline
- Responsive web design
- Compatible with any device and screen dimension
- Background Sync
- Smooth app interactions
- Native-like app UI/UX
- Web push notifications
- and so much more...
