Chrome & PWAs

Updates worth mentioning

This is a Note: a sometimes short, sometimes incomplete, living document.

Chrome 85 #

📸 AVIF image support (status shows it only as available on desktop)

⭐️ App Shortcuts on Windows (it was wrongly announced as available in 84)

📱 getInstalledRelatedApps can now detect Microsoft Store apps on Windows

📱 getInstalledRelatedApps can now detect if your PWA was installed from the browser on Android. You need to specify a related webapp in your manifest and ask the API from within the same scope. I don't understand why you need to specify a related webapp that comes from the same manifest where you define it 🤷‍♂️ (I know it's because of how the spec is defined but it's weird anyway). Have in mind there is no API yet to transfer the navigation to the standalone experience I'd you detect installation.

✨ Chrome for Android is now 64 bits

🏁 Event Timing API

👀 Content Visibility CSS style to let the browser defer rendering of below the fold content

🧪 New Experiments in Origin Trials

  • Portals: seamless navigation between documents for SPAs; you load a portal (similar to an iframe) and then you can make that portal become the main document.
  • Fetch upload streaming

🧪 New Experiments under a flag

  • Web Bluetooth additions: get a list of approved devices

Chrome 84 #

⭐️App Shortcuts-contextual menus now available on the PWA icon for Android: it's a static list of URLs you define in the Web App Manifest

🏃‍♀️Better support for the Web Animation API

🚪Quieter Notifications on abuse-if a website abuses of permission dialogs, Chrome will move into a different mode to protect users from abusive notifications. More about this

☕️Wake Lock-Keep the screen awake preventing phone sleep, useful for PWAs that you can use hands-free (such as using SpeechSynthesis, camera, or other behaviors.

🔢WebOTP-only for Android, it lets the app read incoming SMSs following a specific protocol, useful to speed-up 2FA

📇Content indexing-This is the only feature that I still don't see useful. It let us register offline content that our PWA can serve while offline as a way to expose that content when the user has no connection. What I don't get is the User Experience for that, the Downloads menu 🤔
