PWA (Progressive Web App) is a modern technological solution that combines the functionality of mobile applications with the accessibility of websites. This allows users to use the application without the need to install it from an app store—simply opening it in a browser is enough.
PWA-type applications function like standard websites but offer features characteristic of mobile apps. A user can add such an application to the home screen of their phone or tablet, allowing it to launch similarly to a classic mobile app.
One of the important features of a PWA is the ability to operate even with limited internet access. This is made possible by Service Worker technology, which allows parts of the data to be saved in the device's memory and used offline.
PWAs are also distinguished by their responsiveness, meaning the interface automatically adjusts to various screen sizes—on both computers and mobile devices. Additionally, these types of applications can send push notifications, much like traditional mobile apps.
