Great list of open source projects – focused on front-end projects (which are really the only ones I use). I also like how he broke up the projects into fairly logical/useful categories so I can just jump to the section that I’m interested in. For example, right now, I’m interested in charting libraries and have only really used nvd3, so I’m now interested in trying out a bunch of the other charting libraries listed. Anyways, great list of resources, definitely check it out if you’re looking for UI frameworks, charts, maps, text, video, audio, tables, lazy loading, scrolling, animations, UI elements, templating, HTTP requests, dates (probably not the kind of dates you’re really looking for), events, icons, colors, databases, social. If you find anything good, be sure to star the project and give a shout-out to the author.
