Facebook makes app accessibility easier with React framework updates

Developers can use new tools to help people use their apps

Facebook is making it easier for app developers to build programs that work for people who are visually impaired after the company updated its React and React Native programming frameworks on Monday

The new features let developers designate user interface elements as accessible, which makes it possible for screen readers and other assistive technology to understand what the object in question is. Accessible elements can also be given a label that a screen reader can use to describe what they are.

Applications using React Native can also figure out if the system they're running on has accessibility features turned on, and tweak the way their user interfaces are set up in order to make them more useful for people who are making use of assistive technology. 

Using the new Accessibility API makes it possible for screen-reading programs like Apple's VoiceOver on the iPhone and Google's TalkBack on Android to tell users what an application looks like and how it works. That makes it possible for visually impaired users and other people using assistive features to more easily navigate and use those apps. 

React and React Native are tools that help developers build user interfaces for the Web and mobile apps, respectively. React Native is a particularly important tool, since it works across both iOS and Android, and lets developers reuse code across different platforms. Now, it's possible for developers to build accessible apps across both mobile operating systems as well. 

Facebook has already implemented the new accessibility technology in its own Ads Manager app for iOS and Android, which allows people to create and monitor ad campaigns for the social network from their mobile devices.  The company has been making a push towards improving accessibility in its own apps, and recently enabled the Dynamic Type feature for users on iOS, which lets users make the text inside the app larger.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
