Looks for <code>url(...)</code> definitions in CSS and rewrites them
Simple function that looks for
url(...) definitions in a string of CSS and runs them through your own rewriter function.
Install the module with:
npm install css-url-rewriter
var rewriteCSSURLs = require'css-url-rewriter';// example - add a query string to all URLsvar newCSS = rewriteCSSURLssomeCSSreturn url + '?12345';;
It will process all URLs it encounters by default, even
data: URIs, so you need to check for those manually if you want to handle them differently. The only exception is URLs in 'excluded properties' (see settings).
You can optionally pass in a settings object as a second argument:
var newCSS = rewriteCSSURLssomeCSS settingsreturn url + '?12345';;
Currently there is only one configurable setting,
excludedProperties, which is an array of properties that you want to skip. This setting defaults to
['behavior', '*behavior'] (because you usually don't want to mess with URLs in this proprietary MSIE property, because it has weird relativity rules).
