Ionic supports PWA
The Ionic team are great fans of the progressive web application, which offers an application-like experience using modern web APIs. Since Ionic 3 is built with web technologies that work perfectly in web browsers, this gives you a huge advantage when building your PWA with Ionic, because if you know how to build an Ionic 3 application, then you can easily build a PWA in a short period of time, you just have to add service workers and a web manifest file. We will be building an offline currency converter with PWA support and will finally host it on Firebase hosting.
What makes a web application a PWA?
In simple words, a PWA is meant to be eventually installed to the user's home screen, which means they will access it exactly like a native application. So users expect the same experience as when using a native application. Since Ionic 3 is designed to create a native application experience with standard web technologies, this is already handled.
PWA should be very performant...
