Progressive Web Apps
A Progressive Web App is:
Progressive - Works for every user, regardless of browser choice because it’s built with progressive enhancement as a core tenet.
Responsive - Fits any form factor: desktop, mobile, tablet, or whatever is next.
Connectivity independent - Enhanced with service workers to work offline or on low-quality networks.
App-like - Feels like an app, because the app shell model separates the application functionality from application content.
Fresh - Always up-to-date thanks to the service worker update process.
Safe - Served via HTTPS to prevent snooping and to ensure content hasn’t been tampered with.
Discoverable - Is identifiable as an “application” thanks to W3C manifest and service worker registration scope, allowing search engines to find it.
Re-engageable - Makes re-engagement easy through features like push notifications.
Installable - Allows users to add apps they find most useful to their home screen without the hassle of an app store.
Linkable - Easily share the application via URL, does not require complex installation.
