This extension injects any JS library from CDNJS.com into a page.
There are lots of times I've wanted to inject jQuery on to a page but currently the only options on the store inject a given version of jQuery. I started out planning to just connect with the Google CDN API before realising that sometimes there are other libraries I sometimes want.
Chrome Injector will be able to inject any library available on CDNJS.com into a given page.
This is no where near finished but is just about usable enough to share. Currently it's only able to handle injecting the main file of the latest version of a library, it's lacking a lot of niceties and the UI needs some serious work. It also does no checking to see if that library is already in a page.
