Grunt plugin for fetching URLs and saving the result as local files.

Getting Started

This plugin requires Grunt ~0.4.2

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-fetch-pages --save-dev

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

grunt.loadNpmTasks('grunt-fetch-pages');

The "fetchpages" task

Overview

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

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

Options

baseURL

Type: String

Base url for fetching remote pages via GruntJS "files" feature. Can be omitted when using only the urls feature (see urls option).

destinationFolder

Type: String
Required: yes

Local destination folder for fetched remote urls. This option is mandatory.

urls

Type: Array
Default: []

An optional list of remote urls to fetch. Required properties per element:

  • url: full remote URL to fetch
  • localFile: local file name for fetched page (destination folder is defined by destinationFolder option)

Type: Boolean
Default: true

Also fetch sub pages referenced via links (<a href="">). No fetching of links within sub pages at this time.

ignoreSelector

Type: String
Default: [rel="nofollow"]

Selector for ignoring certain links when following (see followLinks option). The default value matches links with the "rel" attribute set to "nofollow": <a href="" rel="nofollow">.
The selector is applied as $('a:not(ignoreSelector)'), e.g. $('a:not([rel="nofollow"])')

cleanHTML

Type: Boolean
Default: false

Clean fetched pages via htmlclean node module, removing unneeded whitespaces, line-breaks, comments, etc.

fetchBaseURL

Type: Boolean
Default: true

Do not fetch the baseURL when this option is set to false.

Usage Examples

Simple example, fetch base URL and follow links:

grunt.initConfig({
  fetchpages: {
    dist: {
      options: {
        baseURL: 'http://localhost:3000',
        destinationFolder: 'test/www-fetched',
      }
    }
  }
});

Full example with all feasible options set:

grunt.initConfig({
  fetchpages: {
    dist: {
      options: {
        baseURL: 'http://localhost:3000',
        destinationFolder: 'test/www-fetched',
        urls: [
          {url: 'http://localhost:3003/url.html', localFile: 'url.html'}
        ],
        followLinks: true,
        ignoreSelector: '[rel="nofollow"]',
        cleanHTML: false,
        fetchBaseURL: true
      },
      files: [
        {
          src: ['**/*.html', '!url.html'],
          expand: true,
          cwd: 'test/www-root/'
        }
      ]
    }
  }
});
