CSS Relative URL Processor

A small module designed to convert relative asset URL's in CSS files into absolute URL's for deployment to a combo handled CDN (yui.yahooapis.com).

When you request a CSS file from a server with a ComboHandler on it, relative CSS assets are broken by default.

If your CSS looks like this:

.foo {
    background-image: url( foo.png );
}

Located in a file with this path: foo/bar/baz/main.css

Loaded from a ComboHandler like this: /combo?foo/bar/baz/main.css

Your Image will resolve to: /combo/foo.png

When it should resolve to: /foo/bar/baz/foo.png

That's what this module does!

Examples

As a file (from examples/file/):

var cssproc = require('../../lib'),
    path = require('path'),
    fs = require('fs');
 
var file = path.join(__dirname, 'a1/f1/f2/test.css');
 
fs.readFile(file, 'utf8', function(err, data) {
    cssproc.parse({
        root: __dirname,
        path: file,
        base: 'http://yui.yahooapis.com/gallery-123456/'
    }, data, function(err, str) {
        console.log(str);
    });
});

It could also be used inside of a combo handler

Base

The value of base could be:

  • http://foobar.com/path/to where protocol will be forced to HTTP
  • https://foobar.com/path/to where protocol will be forced to SSL
  • //foobar.com/path/to which is protocol agnostic where it uses the protocol for the css file that contains the images.
  • /path/to for absolute paths where it uses the domain and protocol from the css file that contains the images.
  • ['http://server1.com/path/to', '//server2.com/path/to', etc] an array of hosts to loop through and alternate in the file to support domain sharding.
