I decided that I needed to put together a list of essential libraries that I use on a near daily basis for web development that I could use for future reference.
PHP Framework - Symfony - http://symfony-project.org
CSS Framework - Blueprint - http://www.blueprintcss.org/
Javascript Framework - jQuery - http://jquery.com/
Widgets - jQueryUI - http://jqueryui.com/
Lightbox - Fancybox - http://fancybox.net
Video Player - JW Player - http://www.longtailvideo.com/players/jw-flv-player/
Content Scroller - jCarousel - http://sorgalla.com/jcarousel/
Flash Uploader - SWFUpload - http://swfupload.org/
Flash Loader - SWFObject - http://code.google.com/p/swfobject/
Browser-Side Validation - jQuery - Validation - http://docs.jquery.com/Plugins/Validation
I am very much looking forward to getting my hands on this for an upcoming project…
