Notes from Google’s Progressive Web Apps Roadshow

Progressive web apps: a new level of caring about the quality of your user experience

It’s not about a particular bit of technology (though there’s a few good ones), but about creating a web experience thats as seamless as native applications

User experiences need to be:

  1. Reliable (fast to load, never down offline, even if the network is down). Homescreen.
  2. Homescreen: Auto adding to home screen
  3. Performant (around 3 seconds, 20% of your users will have abandoned your experience. After 3 seconds, 40% of users abandon the site). Immersive
  4. Immersive: full screen, theming, orientation
  5. Engaging.
  6. Notifications: push notifications are what turn meh users into daily users
  7. Option to add a website to your home screen. It starts with a splash screen in case you’re offline. And then it runs like an app, doesn’t show a url
