Progressive Web Apps
Progressive Web Apps ➔ Best of the web 💚 Best of native apps. ➔ Useful after the 1st visit ➔ Become more and more powerful with each visit you make 15
Progressive Web Apps ➔Progressive: must work on any device and enhance progressively. ➔Discoverable: in search engines. ➔Linkable: should use the URI to indicate the current state of the application. ➔Responsive: must fit the device’s form factor and screen size. ➔App-like: like a native app and be built on the application shell model, with minimal page refreshes. 17
Progressive Web Apps ➔Connectivity-independent: low connectivity or offline. ➔Re-engageable: push notifications. ➔Installable: installed on the device’s home screen. ➔Fresh: new content should be made available in the app. ➔Safe: hosted over HTTPS to prevent man-in-the-middle attacks. 18

After more than 2 years, what did we all get from PWA?
NOTIFICATIONS!
Don’t be the sheep! Be the wolf fox! Photo credit.
Why PWA might save the world.. ➔ Usability and Accessibility ➔ Increases business revenues ◆ Conversion (new users, finalized actions) >50% ➔ No install nor (huge) storage usage ◆ (0 new apps/35 at first usage) ➔ Available everywhere, without any account ➔ Easy to build up/develop 26
Hold my beer… PWAs on the way to their full potential ➔ Mobile ranking algorithm in search rankings ➔ ONE version to rule them ALL ➔ Innovation and rapid development of feature ◆ Roland’s talk about voice, Reka’s VR, IoT, etc ➔ Keep up with Kardashians, manufacturers ➔ Web stands for the companies/not individual big brothers 27
So.. When to go PWA and when to stay on native?
Hold your horses.. PWAs can’ts ➔ Some HW functionalities ➔ A bit less shiny things ➔ Web standards are not really standards ◆ webcompat.org ➔ .. any others? 30
