YUI Library / YUIConf 2011

In this talk from YUIConf 2011, Yahoo! frontend engineer Gonzalo Cordero reveals how Yahoo! Local used YUI 3 to develop their iOS app using a native Objective-C wrapper with HTML5 and YUI running in a UIWebView. He argues that there's no such thing as a desktop web and a mobile web -- there's just "the web", and YUI is the perfect framework for people who want to write web apps that run everywhere.

In this talk from YUIConf 2011, YUI engineer and former jQuery user Derek Gathright explains why you should consider using YUI to build your web apps. In particular, he stresses how YUI is designed to serve as an extensible set of building blocks (like Legos) and not just a collection of ready-to-use components (like pre-molded plastic toy cars).

NFL.com's Ryan Cannon joined us at YUIConf 2011 to share the story of why NFL.com chose YUI over jQuery, how they migrated a large codebase from Prototype to YUI 3 on a tight schedule, and how they use YUI to create websites and mobile apps for one of the world's most popular sports leagues.

In this talk from YUIConf 2011, YQL engineer Paul Donnelly demonstrates the features of the Yahoo! Pipes editor and explains how you can use Pipes and YQL to power your web apps, create mashups, and more.

In this talk from YUIConf 2011, Jeff Burtoft, Lead Frontend Engineer at USAA, shares what he's learned about building performant and scalable cross-platform mobile web apps using YUI. In the course of the talk, Jeff reveals some of the pitfalls of dealing with device limitations -- particularly when building native-wrapped web apps that run in web views -- and explains how he and his team worked around them using YUI.

In this talk from YUIConf 2011, Meebo engineer and YUI contributor Jeff Craig reveals everything you've always wanted to know about the YUI Loader but were afraid to ask. This is a must-see for anyone doing performance-critical work with YUI 3.

In this talk from YUIConf 2011, YUI engineer Allen Rabinovich shares the process he used to architect and build the new Calendar widget in YUI 3, and explains how you can use a similar process to build your own widgets. He also shows off the new component and reveals a clever performance trick used to speed up the rendering of multiple calendars.

Pat Cavit, a frontend engineer at ArenaNet and an active YUI contributor and community member, joined us at YUIConf 2011 to give this talk on automating build-time website optimizations such as file concatenation, minification, renaming, and more using the Ant build tool.

In this talk from YUIConf 2011, YUI engineer Satyen Desai discusses what he learned about mobile performance -- and how those learnings will feed back into YUI -- when he spent a few months working with the Yahoo! Livestand team on their gorgeous (and blazing fast!) new iPad app.

Mozilla Labs engineer and TC39 representative Dave Herman joined us at YUIConf 2011 to give this keynote talk on the future of JavaScript, covering many of the new features currently under consideration for ES6, the next edition of the ECMAScript standard.

In one of the most popular talks at YUIConf 2011, YUI engineer Eric Ferraiuolo discusses the MVC components of the YUI App Framework and some of the new features coming in YUI 3.5.0 and beyond, including Handlebars-based templating and a new Y.App component that makes the creation of MVC apps easier than ever on desktop, mobile, and the server.

In this keynote talk from YUIConf 2011, Yahoo! JavaScript architect Douglas Crockford drops some science to explain why code style is important in programming -- particularly in JavaScript -- and how tools like JSLint can help.

In this talk from YUIConf 2011, YUI engineer Luke Smith provides a deeply technical overview of the various JavaScript class inheritance and composition patterns (ranging from pseudoclassical to prototypal to a mixture of both) supported by YUI.

In the opening keynote from YUIConf 2011, YUI engineer Dav Glass recaps the past year of YUI development and gives a preview of what's coming in the next few months.
