A Progressive Web App (PWA) is a web app that delivers an app-like experience to users using web compatibilities. These apps meet certain requirements (see below), are deployed to servers, accessible through URLs, and indexed by search engines.
This can work in conjunction with Cordova to provide multiple deploy targets for all your users. You can deploy your app as a PWA as well as Native app and take advantage of both channels.
Ionic allows you to ship your app to not only the app store but also deploy to the mobile web as a PWA.
What is required
To be considered a Progressive Web App, your app must be:
- Progressive – Work for every user, regardless of browser choice, because they are built with progressive enhancement as a core tenet.
- Responsive – Fit 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 – Use the app-shell model to provide app-style navigation and interactions.
- Fresh – Always up-to-date thanks to the service worker update process.
- Safe – Served via HTTPS to prevent snooping and ensure content has not been tampered with.
- Discoverable – Are identifiable as “applications” thanks to W3C manifests and service worker registration scope allowing search engines to find them.
- Re-engageable – Make re-engagement easy through features like push notifications.
- Installable – Allow users to “keep” apps they find most useful on their home screen without the hassle of an app store.
- Linkable – Easily share via URL and not require complex installation.
