PWAs on steroids

on YouTube ↗40m

" summary

Manifest plus service-worker caching makes the site installable, offline and fast; push and pushManager deliver notifications. Demos show vibration, Visibility and Orientation events, geolocation and Network Information, Speech Synthesis working locally, and getUserMedia + canvas screenshots with filters; Speech Recognition is unreliable in live demos. Bluetooth integration is explained (GATT services → characteristics → read/write) but the device demo fails. Case studies (Flipkart, AliExpress, Trivago) report real business gains.
