Readability

Turn any web page into a clean view. This module is based on arc90's readability project.

Features

1. Optimized for more websites.
2. Support encodings such as GBK and GB2312.
3. Converts relative urls to absolute for images and links automatically(Thank Guillermo Baigorria & Tom Sutton).

Install

npm install node-readability

Usage

read(html [, options], callback)

Where

• html url or html code.
• options is an optional options object
• callback is the callback to run - callback(error, article, meta)

Example

var read = require('node-readability');

read('http://howtonode.org/really-simple-file-uploads', function(err, article, meta) {
  // The main body of the page.
  console.log(article.content);
  // The title of the page.
  console.log(article.title);

  // The raw HTML code of the page
  console.log(article.html);
  // The document object of the page
  console.log(article.document);
  
  // The response object from request lib
  console.log(meta);
});

NB If the page has been marked with charset other than utf-8, it will be converted automatically. Charsets such as GBK, GB2312 is also supported.

Options

node-readability will pass the options to request directly. See request lib to view all available options.

node-readability has additional option cleanRules which allow set your own validation rule for tags. If true rule is valid, otherwise no. options.cleanRules = [callback(obj, tagName)]

read(url, {
        cleanRulers : [
          function(obj, tag) {
            if(tag === 'object') {
              if(obj.getAttribute('class') === 'BrightcoveExperience') {
                return true;
              }
            }
          }
        ]
      }, function(err, article, response) {});

article object

content

The article content of the web page. Return false if failed.

The document of the web page generated by jsdom. You can use it to access the DOM directly(for example, article.document.getElementById('main')).
