Earlier this decade, Progressive Web Apps (PWAs) started to become commonplace in the mobile and web worlds. By allowing developers to access features and functionality ordinarily reserved for native applications, PWAs can allow users a richer application experience than normal dynamic web pages — even more so than HTML5.
Following up on their 2017 announcement, Google is now allowing PWAs that make use of the Trusted Web Activities (TWA) API into its Play Store. TWA is Google's way of allowing app developers to create PWAs with minimal native code while still allowing the promise of PWAs: greater access to native device features such as push notifications.
