First of all, I don't post nearly enough on the forum, gotta get back into the habit of this
So, Progressive Web Apps are soooo hot right now, but they're pretty difficult to understand considering they're a collection of Web APIs supported on new browsers, some new design concepts, and some marketing terms that big companies like Google are starting to push.
Long term, the Ionic team is super excited about Progressive Web Apps because they give Ionic developers yet another way to deploy apps to reach a totally new audience outside of the app stores. The mobile web and Google search draws tons of users to websites, and many users never install app store apps despite tons of install banners and interstitials. Since Ionic apps are primarily built with web content, Ionic apps can run in the app store AND the mobile web as a Progressive Web App with the exact same code. That's a major advantage over our native app developer friends!
Today, we're taking the first step towards bringing Progressive Web App support into Ionic (a long process, to be sure), and we just posted our first blog with a high level overview of what a Progressive Web App actually is. I hope you enjoy it and let us know if you have any questions about it!
