ascrape

Nodejs module for extracting web page content using Cheerio.

This module is based on luin's readability project.

npm install ascrape

Usage

var scrape = require('ascrape');

scrape(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 scrape = require('ascrape');

scrape('http://howtonode.org/really-simple-file-uploads', function(err, article, meta) {
  // Main Article
  console.log(article.content.text());

  // Title
  console.log(article.title);

  // Article HTML Source Code
  console.log(article.content.html());
});

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

ascrape will pass the options to request directly. See request lib to view all available options.

ascrape has one additional option:

• preprocess - which should be a function to check or modify downloaded source before passing it to ascrape.

scrape(url, {
  preprocess: function(source, response, contentType, callback) {
    if (source.length > maxBodySize) {
      return callback(new Error('too big'));
    }
    callback(null, source);
  }, function(err, article, response) {
    //...
  });

• title - The article title of the web page. It's may not same to the text in the <title> tag.

• excerpt - The article description from any description, og:description or twitter:description <meta>
