Uncaught TypeError when trying to browserify a node module

I'm trying to find a way I can use this algorithm within a function on the client side. The Module is called RAKE and I'm trying to wrap it around a function so I can use it on the client side by browserifying it.

Here is the github for RAKE: https://github.com/waseem18/node-rake

try.js (compiling this) into bundle.js

var rake = require('node-rake')
// Will produce keywords
function rake_it(text){

    return rake.generate(text)
}

console.log(rake_it("LDA stands for Latent Dirichlet Allocation"))

Ideally I want to use this function when a user types inside of a form and generate the keywords from the text.

So I compile try.js doing browserify try.js -o bundle.js

I put bundle.js into an index.html for testing but get this error inside of the console window.
