Important Announcement Regarding YUI

The Yahoo User Interface library (YUI) has been in use at Yahoo since 2005, and was first announced to the public on February 13, 2006. Although it has evolved tremendously since that time, YUI has always served the same overarching purpose of providing a comprehensive toolkit to make it easier for developers to create rich web applications. As such, YUI is an important part of Yahoo?s history: millions of lines of code relying on YUI have been written and are still in use at Yahoo today. However, it has become clear to us that the industry is now headed in a new direction.

As most of you know, the web platform has been undergoing a drastic transformation over the past few years. JavaScript is now more ubiquitous than ever. The emergence of Node.JS has allowed JavaScript to be used on the server side, opening the door to creating isomorphic single page applications. New package managers (npm, bower) have spurred the rise of an ecosystem of 3rd party, open source, single-purpose tools that complement each other, embracing the UNIX philosophy and enabling very complex development use cases. New build tools (Grunt and its ecosystem of plugins, Broccoli, Gulp) have made it easier to assemble those tiny modules into large, cohesive applications. New application frameworks (Backbone, React, Ember, Polymer, Angular, etc.) have helped architect web applications in a more scalable and maintainable way. New testing tools (Mocha, Casper, Karma, etc.) have lowered the barrier of entry to building a solid continuous delivery pipeline.

Standard bodies (W3C, Ecma) are standardizing what the large JavaScript frameworks have brought to the table over the years, making them available natively to a larger number of devices. Finally, browser vendors are now committed to making continuous improvements to their web browsers while aligning more closely with standards. With so called ?evergreen web browsers?, which are making it easier for users to run the latest stable version of a web browser, we can expect a significant reduction in the amount of variance across user agents.

The consequence of this evolution in web technologies is that large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don?t want to be locked into. As a result, the number of YUI issues and pull requests we?ve received in the past couple of years has slowly reduced to a trickle. Most core YUI modules do not have active maintainers, relying instead on a slow stream of occasional patches from external contributors. Few reviewers still have the time to ensure that the patches submitted are reviewed quickly and thoroughly.

Therefore, we have made the difficult decision to immediately stop all new development on YUI in order to focus our efforts on this new technology landscape. This means that, going forward, new YUI releases will likely be few and far between, and will only contain targeted fixes that are absolutely critical to Yahoo properties.

The mission of the YUI team at Yahoo continues to be to deliver the best next-generation presentation technologies with an initial focus on internal developers. We remain optimistic about the future of web presentation technologies and are eager to continue working with the external frontend community to share and learn together.

Cool to know that 6 months ago I woulda recognized almost none of the products/services mentioned in the bolded. Been learning about modern ways* of doing stuff all over the place.



* and it's gonna keep moving forward like this; even MS VS recognizes that:
