I guess we’re just plugging our own apps. Our company has spent a considerable amount of time optimizing our site for PWA compatibility. We have a lot of users so these kind of optimizations are worthwhile financially but also substantially ease the load on our front end and back end servers.

PWA features:

- Installable

- Offline caching

- Push Notifications

- Server side rendering

- Heavy use of edge caching (JS, CSS, images, JSON from our API), HTML caching coming soon

- Auto WebP Images support

- Preload/preconnect

- WebShare, Web Payments (Apple/Android Pay)

- Automatic image optimization using a custom edge-cached image manipulation service

- Self updating: despite being cached it will immediately upgrade itself if a new build is detected
