The increase in Progressive Web Applications (PWAs) is the latest attempt to bring back the mobile web in response to users' "app fatigue". Originally proposed by Google in 2015, PWAs are web applications that take advantage of the latest technologies to combine the best of web and native mobile applications. Using a set of open standard technologies such as, service workers, the app manifest, and cache and push APIs, we can create applications that are platform independent and deliver app-like user experiences. This brings parity to web and native applications and helps mobile developers reach users beyond the walled garden of the app stores. Think of PWAs as websites that act and feel like native apps.
