YUI 3: The Yahoo! User Interface Library

Welcome to YUI 3!

The YUI Library is a set of utilities, infrastructure components, and widgets written in JavaScript and CSS for building richly interactive web applications. It is available under a BSD license and is free for all uses.

This is the active working source tree for YUI 3. It contains work in progress toward the next YUI 3 release, and may be unstable or change without notice. We encourage you to use the latest source for evaluation purposes, testing new features and bug fixes, and to provide feedback on new functionality. Please refer to the "Latest Production Release" link above if you're looking for the latest stable release of YUI recommended for production use.

The YUI source tree includes the following directories:

  • api: Generated API docs for the entire library in HTML format. This documentation is built and committed automatically from the contents of the src directory.
  • build: Built YUI source files. The built files are generated at development time from the contents of the src directory. The build step generates debug files (unminified and with full comments and logging), raw files (unminified, but without debug logging), and minified files (suitable for production deployment and use).
  • sandbox: Experiments and works in progress, including unreleased future components. Here there be dragons.
  • src Raw unbuilt source code (JavaScript, CSS, image assets, ActionScript files, etc.) for the library. Beginning with YUI 3.4.0, the src directory also contains all module-specific documentation, tests and examples. All modifications to the library and its documentation should take place in this directory.

The individual component directories under the src directory contain Ant build files (build.xml and others) which can be used to build individual modules using the YUI Builder. The YUI Builder is part of the "builder" project, also available on GitHub at https://github.com/yui/builder

The README file in the componentbuild directory of the Builder project covers the installation and use of the build tool.
