Progressive Web Apps (PWAs) Explained
What are PWAs, and why are they replacing native apps for many use cases?
Bridging the Gap
Progressive Web Apps (PWAs) are web applications built using modern web technologies but designed to deliver a user experience akin to native mobile or desktop apps. They are discoverable, installable, and work independent of network connectivity.
The Power of Service Workers
The defining technology behind PWAs is the Service Worker. A service worker is a script that your browser runs in the background, separate from a web page. It enables features like push notifications and background sync. Crucially, it intercepts network requests, allowing the app to serve cached assets and function offline.
Benefits of PWAs
PWAs bypass the need for app store approvals, allowing developers to push updates instantly. They have smaller installation sizes compared to native apps and provide seamless experiences through integration with device hardware via web APIs like the Web Share Target API.
