Yahoo Design Patterns Library

This has been around for a while but I just came across , but in case you haven't seen it and you're doing web-based development, you really should check out the Yahoo Design Patterns Library. It is a part of the Yahoo! developer network (something really new to me, as I did not go to yahoo for a while). It's simply an excellent resource for web developers. I just went through a part of the site and here is a part of some interesting stuff going on in the yahoo developer network ...

1. The JavaScript developer center: This section provides a lot of articles and documentation on how to use JavaScript with yahoo! products and services and also many code samples you can learn (wink, wink) from and make use of in your own web and client applications.
2. The UI Library: The Yahoo! User Interface Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, HTML and AJAX. All the components in the Yahoo! User Interface Library have been released as open source under a BSD license and are free for all uses.
3. The Widget engine: The Yahoo! Widget Engine (formerly known as Konfabulator) is a JavaScript runtime engine for Windows and Mac OS X, which help you create widgets for your desktop such as clocks, calculators, stock tickers etc.
4. Maps API: There are three API families for Yahoo! maps - AJAX, Flash, and the original Simple API.
5. The PHP developer center: As you might have known, Yahoo! runs PHP, and naturally have a PHP developer center where they provide HOWTO articles, code samples, and community resources for using Yahoo! Web services with PHP.

This is but a very small part of their developer center. You can access a host of other REST based web services for almost all their products, including flickr, de.icio.us etc. The Yahoo! web services blog provides up-to-date information of the services provided by yahoo. The Yahoo! developer community section contains links to sample applications implemented by other Yahooo! developers and also support groups for each of the product web service sections.
