The cdn-url loader works like the file loader, but can return a Data Url if the file is smaller than a limit. Otherwise it returns a link to a specified resource on a CDN.
The limit can be specified with a query parameter. (Defaults to no limit)
If the file is greater than the limit the CDN link is used.
require("cdn-url?limit=10000!./file.png");
// => DataUrl if "file.png" is smaller that 10kb
require("cdn-url?mimetype=image/png!./file.png");
// => Specify mimetype for the file (Otherwise it's inferred from extension.)
