API

new CacheBuster(options)

options.checksumLength

Optional

options.random

Generates the checksum based on a random sha1 hash and not on the file contents.
Useful for changing the file names on each deploy regardless if the content was changed or not.

Optional

Type: Boolean Default: false

options.pathFormatter

Specify a custom formatting function for busted paths. The default will output filenames like /path/to/basename.[hash].ext.

Optional

Type: Function Default: null

An example for outputing a custom hash prefix:

{
    pathFormatter: function(dirname, basename, extname, checksum) {
        return require('path').join(dirname, basename + '._v' + checksum + extname);
    }
}

CacheBuster.resources()

Renames and collects resources according to their MD5 checksum.

CacheBuster.references()

Rewrites references to resources which have been renamed according to their MD5 checksum.
