Dev.Opera is a community resource site where developers can share tips, tricks, extensions and more. Opera Software ASA 2012-10-23T13:13:50Z Daniel Davis The Network Service Discovery API enables web pages to communicate with devices advertising themselves on the network via different discovery protocols in a peer-to-peer configuration. Now you can use JavaScript to find a UPnP server locally, browse its content and send that content to a UPnP client. This article, with links to experimental builds, shows you how. http://dev.opera.com/articles/view/network-service-discovery-api-support-in-opera 2012-10-23T13:13:50Z Andreas Tolf Tolfsen Opera Mobile brings the Web to millions of people through their mobile phones and other non-desktop devices. Opera believes in giving people access to the full Web, and not making the distinction of a “mobile web”. To help automated mobile testing, we've updated the Opera Mobile Emulator so it can talk to our browser automation library, OperaDriver. http://dev.opera.com/articles/view/introducing-mobile-browser-automation 2012-08-02T17:14:13Z Chris Mills Opera is proud to present an experimental labs release that includes support for SPDY, Google's new networking protocol that enables performance increases across the web. Please try it out, and let us know what you think! http://dev.opera.com/articles/view/opera-spdy-build 2012-07-06T09:58:01Z Chris Mills We've been working hard recently to improve the functionality available inside Opera extensions, and today we are proud to reveal some of the fruits of our labours. In this article we'll share with you some new experimental desktop builds that feature three new extension APIs: the screenshot API, the resource loader API, and several updates to the URL filter API. http://dev.opera.com/articles/view/new-extension-apis-screenshot-resource-loader-url-filter 2012-05-16T13:33:50Z Bruce Lawson Through our site compatibility work, we have experienced that many site authors only use -webkit- prefixed CSS, thereby ignoring other vendor prefixes and not even including an unprefixed equivalent. This leads to a reduced user experience on non-WebKit browsers, as they don't receive the same shiny effects, even although they support them. To tackle this problem, we are releasing an experimental Opera Mobile Emulator build with experimental support for selected -webkit- prefixes. http://dev.opera.com/articles/view/opera-mobile-emulator-experimental-webkit-prefix-support 2012-04-27T15:21:17Z Andreas Bovens When adding extensions support to our Presto engine, a lot of time was spent behind the scenes so as to make our extensions framework very versatile and lightweight, with the aim of using it on other platforms as well. Today, we're happy to present you with an early preview of extensions running on Opera Mobile! http://dev.opera.com/articles/view/extensions-opera-mobile-labs 2012-04-03T12:25:55Z Chris Mills Opera is proud to unveil a labs build of Opera Mobile 12, for devices built on MIPS architecture, which has already been run successfully on top of Android Ice Cream Sandwich. http://dev.opera.com/articles/view/opera-mobile-12-android-ics-mips 2012-02-27T08:25:46Z Chris Mills Opera is proud to unveil a labs build of Opera Mobile 12, for devices built on Intel x86 architectures, which has already been run successfully on top of Android Ice Cream Sandwich. http://dev.opera.com/articles/view/opera-mobile-12-android-ics-x86 2012-02-27T08:25:43Z Mostyn Bramley-Moore Since our previous releases of Opera Mobile for MeeGo, we have noticed that a lot of our users have been hanging out for an official Opera Mobile build for the Nokia N9 and N950 Harmattan phones.
