'''Cdnjs''' is a community driven, peer reviewed script repository, non-profit and open-source [[Content Distribution Network]], for popular web development frameworks, with a wide range of community-driven projects hosted on a global CDN to speed up the web as a whole.

In January 2011, Ryan Kirkman and Thomas Davis created the service,<ref name="original-site">{{Cite web|title=cdnjs.com: the missing cdn|url=http://www.cdnjs.com/|url-status=live|archive-url=https://web.archive.org/web/20110125232824/http://www.cdnjs.com/|archive-date=January 25, 2011|access-date=September 3, 2020|website=cdnjs.com}}</ref> launching it on GitHub on February 25, 2011.<ref name="cf-art-1">{{cite web|title=CDNJS: Community Moderated Javascript Libraries + CloudFlare|date=16 June 2011 |url=https://blog.cloudflare.com/cdnjs-community-moderated-javascript-librarie/|access-date=18 April 2019|publisher=Cloudflare}}</ref><ref name="cat5-tv">{{Cite news|date=May 3, 2014|title=345 - Behind CDNJS - #Cat5TV Category5TV|url=https://www.youtube.com/watch?v=Pjj-5YEy1Z0|access-date=September 3, 2020}}</ref><ref name="the-changelog">{{Cite news|date=June 21, 2011|title=63: CDNJS with Thomas Davis and Ryan Kirkman|work=The Changelog|url=https://dev.to/changelog/63-cdnjs-with-thomas-davis-and-ryan-kirkman|access-date=September 3, 2020}}</ref> It initially served content through [[Amazon CloudFront]].<ref name="cf-art-1" /><ref name="treehouse">{{cite web|title=cdn js {{!}} Treehouse Blog|url=https://blog.teamtreehouse.com/cdn-js|access-date=18 April 2019}}</ref> On June 15, 2011,<ref name="cf-tweet">{{Cite tweet|user=Cloudflare|number=81512881341997056|date=16 June 2011|title=CDNJS: all the Internet's best Javascript libraries, now in a single, fast repo powered by CloudFlare! http://blog.cloudflare.com/cdnjs-community-moderated-javascript-librarie}}</ref> cdnjs partnered with Cloudflare, who provided the CDN and [[subdomain]] cdnjs.cloudflare.com for the project.<ref name="cf-art-1" /><ref name="cat5-tv" /><ref name="the-changelog" /><ref name="techcrunch">{{Cite web|last=Perez|first=Sarah|date=June 24, 2019|title=Cloudflare issues affecting numerous sites on Monday AM [Update: fixed]|url=https://techcrunch.com/2019/06/24/cloudflare-outage-affecting-numerous-sites-on-monday-am/|access-date=September 3, 2020|website=TechCrunch}}</ref>
