grunt-dom-massager

Manipulate the dom using cheerio via grunt task

Getting Started

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-dom-massager --save-dev

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

grunt.loadNpmTasks('grunt-dom-massager');

The "dom_massager" task

Overview

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

grunt.initConfig({
  dom_massager:{
    read_test: {
      options: {
        writeDom: false,
        selectors: {
          ".read .classy": {
            action: "html",
            output: "dom.read.classy"
          },
          ".read #idface":{
            action:"text",
            output:"dom.read.idface"
          }
        }
      },
      src:'test/fixtures/test.html'
    },
    write_test: {
      options: {
        writeDom:true,
        selectors: {
          ".write #deleteme": {
            action:"remove"
          },
          ".write #after": {
            action:"append",
            input:["<a href='blah'></a>"]
          },
          ".write #before":{
            action:"prepend",
            input:["<a href='zappo'></a>"]
          }
        }
      },
      files: {
        'tmp/': ['test/fixtures/test.html'],
      },
    },
  }
});

Options

options.writeDom

Type: Boolean Default value: false

A boolean that determines if the dom manipulation should be saved to disk when completed.

options.xmlMode

Type: Boolean Default value: false

Use XML mode for underlying parser. See Cheerio Documentation for more information.

options.normalizeWhitespace

Type: Boolean Default value: false

Normalize whitespace in incoming file for parser (this can affect your output whitespace). See Cheerio Documentation for more information.

options.selectors

Type: Object Default value: {}

An object containing valid selectors to be used for manipulation actions

{
  action:'attr' //cheerio action to perform
  input:['attrName'] //cheerio method arguments as array (optional)
  output:'dom.attrs.value' //grunt.config key to store any output values in
}

options.selectors.action

Type: String Default value: ''

The action string denotes what cheerio method to call on a given selector. See Cheerio Documentation for more information.

options.selectors.input

Type: Array Default value: []

An array containing any arguments to be passed to the cheerio method. Typically this will be chunks of markup for appending optionally including grunt template values

options.selectors.output

Type: String Default value: ''

An string to use for grunt.config.set key for any output from the cheerio action. This allows you to read in attributes or dom to a grunt config either for later templating or for pulling paths of script/link embeds for further manipulation
