Progressive Web Apps can do more than just rendering content on the screen or connecting to web services. PWAs can deal with files from the file system, they can interact with the system's clipboard, they can access hardware that is connected to the device, and much more. Every Web API is available for your PWA, and there are some extra APIs available when your app is installed.
