What’s new in Chrome 48?

Chrome 48 allows users to take immediate action on notifications with custom buttons; the new Developer Tools Security panel makes it easier debug mixed content issues and ensure your site is properly served over HTTPS and you can now add presentation mode to mobile apps, easily casting content to a second screen. +Pete LePage has all the details and how you can use these new developer features in Chrome 48!

Web Bluetooth API Sample Apps
I’ve been having a lot of fun playing with the Chrome team’s implementation of the Web Bluetooth API. Today we published my latest sample app to control Anki’s Overdrive racing cars: https://www.youtube.com/watch?v=Vg2e1jOug00
Anki has done a great job using a mobile app to use BLE to control the self-driving racing cars. Now you can do the same from a web page without installing any apps.

For my first sample app I made grumpy cat fly using the PowerUp plane: https://www.youtube.com/watch?v=tRMcMDIyIGQ
It was a bit tricky to get the ballast just right for the balloons but coding the app was simple using the PowerUp online docs.

Then I wrote a web app to print some text and a graphic on a BLE thermal printer: https://github.com/WebBluetoothCG/demos/tree/gh-pages/bluetooth-printer
I contacted the printer OEM to get access to their SDK. Printing text was easy to get it working, but the graphics required more complicated bit-level pattern logic.

Probably my favorite web app was to awaken the force in Sphero’s BB-8 toy:
https://github.com/WebBluetoothCG/demos/tree/gh-pages/bluetooth-toy-bb8
Sphero has an SDK and the BB-8 toy works mostly like their earlier Ollie toy, so there are lots of sample code online from other developers that I learned from. 

I’m very excited to see how all of this will come together with Google’s IoT strategy. You could use the Physical Web to discover the web pages for physical devices and then use either the Web Bluetooth API for devices that are not online or the Weave API for Brillo devices that are online. It is going to be a very interesting year for hacking devices!

Chrome is rolling out support for the Web Bluetooth API for desktop, mobile and ChromeOS. You can follow the Web Bluetooth implementation status:
https://github.com/WebBluetoothCG/web-bluetooth/blob/gh-pages/implementation-status.md
Take a look at all the great sample apps we now have for the Web Bluetooth API: https://github.com/WebBluetoothCG/demos
Follow these instructions to write your own Web Bluetooth app: https://developers.google.com/web/updates/2015/07/interact-with-ble-devices-on-the-web

New experimental feature, give it a try!
 
CSS font-display property is now available in Chrome Canary! \o/

It allows you to customize how web fonts are displayed when the page is being rendered -- e.g. should the browser block text rendering until the font is fetched (default in Chrome, FF, Safari) vs. use fallback and then swap the font once fetched vs. check cache and use first available font vs... check out the full spec at: http://tabatkins.github.io/specs/css-font-display/

To test drive it in Chrome Canary:
- Boot up Chrome Canary
- Open chrome://flags
- Enable "enable-experimental-web-platform-features" flag
- Reboot Canary

Demo: http://output.jsbin.com/nigahi/latest/quiet
Visual WPT trace: http://www.webpagetest.org/video/compare.php?tests=151201_PQ_VA6-r:1-c:0

This is a much needed feature, so happy to see this! Give it a try and ping us with any feedback. If all goes well, hoping to see this in Chrome stable in early 2016!

Are you using Page Visibility API? You should be!
 
Don't lose user and app state, use Page Visibility API: http://bit.ly/1Lr81Sv.

Counting on pagehide, beforeunload, or unload events to save user data, app state, beacon your analytics, etc? Well, I can guarantee that you're missing a lot of mobile sessions, because those won't fire whenever your app/tab transitions to a background state. You should be using Page Visibility API.

+Ilya Grigorik lame! Is it difficult for native apps to detect when another app's window is on top of it? I thought native apps were "sooooooo" powerful according to everyone. =[
