Bundle Bust builds JSON manifests.

Use grunt-bundle-bust to hash each file in a directory, and then hash the filepath:hash pairs. The intent is that this provides fodder for a cache-busting URL scheme. You can either rename individual files, or use a directory-level versioning scheme (particularly useful for resource bundles combined using RequireJS or something similar).

Usage

bundleBust is a grunt multi-task. Basic config looks like this.

bundleBust: {
  multitaskName: {
    options: {
      destProp: "manifest" //The grunt.config property to write the
                           //manifest to.  Optional.
    },
    src: ["tasks/**"],     //The files to process.
    dest: "manifest.json", //The destination manifest file.
  }
}

Output format

The output format is the same for file output, or destination property output.

{
  hash: "sha1", //the hash for the entire bundle
  files: {
    "file/path": "sha1" //the hash for each individual file
  }
}
