What's TextRank? It's an algorithm that adapts Google's PageRank to auto-magically build a tag cloud from a text.

Usage

Add text rank to your package.json.

 "dependencies": {

    //...

    "text-rank": "git://github.com/frankandrobot/text-rank.git#master"
  }

Then just do

var textrank = require('text-rank'),

    rslt = textrank.generateTags("Content ...")

The result will be a JSON object with a tags property containing an array of tags

Run the tests

npm install //you may need to do sudo npm install

jasmin-node tests
