A type of web application that uses modern web technologies to provide users with a mobile app-like experience within a web browser. PWAs are designed to be fast, reliable, and engaging, and they offer a range of features that were previously only available to native mobile apps. PWAs use web technologies such as HTML, CSS, and JavaScript to provide features such as offline support, push notifications, and home screen installation. They can also be designed to be responsive and adaptive to different screen sizes, making them ideal for use on both mobile and desktop devices.
PWAs were introduced from 2016 as an alternative to native (device-specific) applications, with the advantage that they do not require separate bundling or distribution for different platforms. They can be used on a range of different systems, including desktop and mobile devices. Packaging and publishing a PWA, as an installable app, to digital distribution systems, such as the Apple App Store, Google Play, or the Microsoft Store on Windows, can optionally be performed.
