Goodbye, app store! Progressive Web Apps (PWA) is an application model that empowers web applications to use “native” features such as offline capability or push notifications. PWAs can be installed on the device by simply adding them to the home screen. With Google, Apple and Microsoft on board, PWA are here to stay. But how do app developers and vendors make money in a post-app store age? Fortunately, there’s an answer to that: The Payment Request API. This feature allows online shops, websites and apps to display a convenient, consistent user interface for online payments. Thinktecture’s Christian Liebel (@christianliebel) shows what you can do with Payment Request API.
