##API

options - object containing next options:

• indexFile: filename for index page (optional, default: 'index.html')
• srcToLoad: array of objects to load, specifies selectors and attribute values to select files for loading (optional, see default value in lib/defaults.js)
• directories: array of objects, specifies relative directories for extensions. If null all files will be saved to path (optional, see example below)

callback - callback function (optional), includes following parameters:

• error: if error - Error object, if success - null
• result: if error - null, if success - object containing:
  • html: html code of index page

##Examples Let's scrape http://nodejs.org/ with images, css, js files and save them to /path/to/save/. Index page will be named 'myIndex.html', files will be separated into directories:

• img for .jpg, .png (full path /path/to/save/img)
• js for .js (full path /path/to/save/js)
• css for .css (full path /path/to/save/css)
• font for .ttf, .woff, .eot, .svg (full path /path/to/save/font)

scraper.scrape({
  url: 'http://nodejs.org/',
  path: '/path/to/save',
  indexFile: 'myIndex.html',
  srcToLoad: [
    {selector: 'img', attr: 'src'},
    {selector: 'link[rel="stylesheet"]', attr: 'href'},
    {selector: 'script', attr: 'src'}
  ],
  directories: [
    {directory: 'img', extensions: ['.jpg', '.png']},
    {directory: 'js', extensions: ['.js']},
    {directory: 'css', extensions: ['.css']},
    {directory: 'fonts', extensions: ['.ttf', '.woff', '.eot', '.svg']}
  ]
}, function (error, result){
    console.log(result);
});
