Grunt task for generating an HTML5 AppCache manifest from the specified list of files.

This plugin requires Grunt ~0.4.1

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-appcache --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-appcache');

In your project's Gruntfile, add a section named appcache to the data object passed into grunt.initConfig().

grunt.initConfig({
  appcache: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
})

Type: String Default value: process.cwd()

The absolute or relative path to the directory to consider as the root of the application for which to generate the cache manifest.

Type: Boolean Default value: true

Specifies if to ignore the cache manifest itself from the list of files to insert in the "CACHE:" section.

Type: Boolean Default value: false

Specifies whether to write the "prefer-online" entry in the "SETTINGS:" section or not. More information.

String indicating the output path for the AppCache manifest.

A descriptor for the "CACHE:" entries. A cache descriptor can be either a String or an Array of Strings, in the format accepted by the patterns argument to grunt.file.expand. Alternatively, this argument can be an Object containing the optional properties patterns (a cache descriptor, as defined earlier) and literals (String or Array of Strings to insert as is in the "CACHE:" section).

Files to be ignored and excluded from the "CACHE:" entries. This parameter has been deprecated since v0.1.4, when proper support for the ! prefix to the glob patterns was added (this serves the same purpose while being more concise).

String or Array of Strings to insert as is in the "NETWORK:" section.

String or Array of Strings to insert as is in the "FALLBACK:" section.

In this example, the module is set to generate an AppCache manifest from the contents of the static directory, placing the resulting manifest in static/manifest.appcache. The basePath option allows the module to generate paths relative to the static directory, instead of the directory where the gruntfile resides.

grunt.initConfig({
  appcache: {
    options: {
      basePath: 'static'
    },
    all: {
      dest: 'static/manifest.appcache',
      cache: 'static/**/*',
      network: '*',
      fallback: '/ /offline.html'
    }
  }
})

The next example uses the extended syntax to the cache parameter:

grunt.initConfig({
  appcache: {
    options: {
      basePath: 'static'
    },
    all: {
      dest: 'static/manifest.appcache',
      cache: {
        patterns: [
          'static/**/*',         // all the resources in 'static/'
          '!static/ignored/**/*' // except the 'static/ignored/' subtree
        ],
        literals: '/'            // insert '/' as is in the "CACHE:" section
      }
    }
  }
})
