Web Development Intermediate

What is Progressive Web App (PWA)?

A web application that uses modern web capabilities to deliver app-like experiences with offline support and push notifications.

PWAs combine the reach of websites with the capabilities of native apps. Key technologies include Service Workers (offline support, background sync), Web App Manifest (installability), and Push API (notifications).

PWAs work on any device, can be installed on the home screen, work offline, and receive push notifications. They avoid app store distribution requirements while providing native-like experiences.
