This is an example of a PWA built using Preact, Webpack, and some small opinions. Please do not think of this as the way to build your application. Instead, view this as an example of some concepts used in modern web applications (sw, h2, h2push). I've focused mostly on first initial load performance, with the small caveat of using Webpack instead of Rollup. I'd like the route based code splitting to provide a extensible model for keeping initial view rendering costs low.
