Readability.js

A standalone version of the readability library used for Firefox Reader View. Any changes to Readability.js itself should be reviewed by an appropriate Firefox/toolkit peer, such as @leibovic or @thebnich, since these changes will be automatically merged to mozilla-central.

To test local changes to Readability.js, you can run your own instance of readable-proxy to compare an original test page to its reader-ized content.

Usage

To parse a document, you must create a new Readability object from a URI object and a document, and then call parse(). Here's an example:

var location = document.location;
var uri = {
  spec: location.href,
  host: location.host,
  prePath: location.protocol + "//" + location.host,
  scheme: location.protocol.substr(0, location.protocol.indexOf(":")),
  pathBase: location.protocol + "//" + location.host + location.pathname.substr(0, location.pathname.lastIndexOf("/") + 1)
};
var article = new Readability(uri, document).parse();

This article object will contain the following properties:

• uri: original uri object that was passed to constructor
• title: article title
• content: HTML string of processed article content
• length: length of article, in characters
• excerpt: article description, or short excerpt from content
• byline: author metadata
• dir: content direction

Optional

Readability's parse() works by modifying the DOM. This removes some elements in the web page. You could avoid this by passing the clone of the document object while creating a Readability object.

var documentClone = document.cloneNode(true); 
var article = new Readability(uri, documentClone).parse();   

Tests

To run the test suite:

$ mocha test/test-*.js

To run a specific test page by its name:

$ mocha test/test-*.js -g 001

To run the test suite in TDD mode:

$ mocha test/test-*.js -w

Combo time:

$ mocha test/test-*.js -w -g 001

Benchmarks

Benchmarks for all test pages:

$ npm run perf

Reference benchmark:

$ npm run perf-reference
