Pokedex.org: a progressive webapp for Pokémon fans
I decided to put these ideas together and build a webapp with a rich, interactive experience that’s every bit as compelling as a native app, but is also "just" a web site. Following guidelines from the Chrome team, I built Pokedex.org – a progressive webapp that works offline, can be launched from the home screen, and runs at 60 FPS even on mediocre Android phones. This blog post explains how I did it.
