Progressive Web Apps
A progressive web app (PWA) is a website that has countless characteristics that were once the sole domain of native apps. It could therefore be described as a symbiosis of a responsive website and an app.
In addition to their characteristics as websites, progressive web apps provide many special functions that were once known only from native apps.
Add-to-homescreen function can be called up with most web browsers via the hamburger menu icon. If a progressive web app is opened and added to the homescreen of the mobile phone, a symbol specific to the PWA appears. By clicking on the symbol, the PWA is opened, even if there is no online connection. The add-to-homescreen function means that no app has to be installed that would take up additional memory.
Push notifications are also known from native apps. Operators of the progressive web app can use this feature to notify users of promotions, price reductions or events and thus increase the interaction rate.
By means of the caching function of the service worker, content that has already been called up once is also available offline. This feature, too, reminds of native apps that do not require internet connection. Progressive web apps consistently take an offline-first approach.
