Node.js use installed package in public/javascripts file

Question

I have installed a package using 'npm install package-name' and now I am wondering how I can use this package in my global.js file which is in the public/javascripts folder?

I have tried using 'var name = require('package-name');' in the global.js file however this does not seem to be working. Am I meant to reference the package some place else?

Any help would be appreciated. Thank you.

Please look at my response for the below answer. Thank you for your response. — Shazam

So the short answer is use the browserify. Really understanding all the implications of sharing code between node and the browser is somewhat of a lengthy topic, so please take the time to read the tutorials and the handbook. But the basic idea is

in your global.js file, load the module from node with var name = require("package-name"); as you are doing.
Transform your file with browserify a la browserify public/javascripts/global.js > public/javascripts/main.js
change your HTML <script> tag to load the new main.js file.

Thank you for your reply! I have installed browserify and transformed my global.js to the main.js and changed the html script reference to the new main.js. However, I am getting the "Cannot find module kmeans" error. I have installed the package 'node-kmeans' and it is in my 'node_modules' folder and I am trying to reference the 'node-kmeans/lib/kmeans.js' file by using 'var kmeans = require('kmeans'). Is there anything I am doing wrong?

Use require("node-kmeans"); the name you pass to require is the same name you passed to npm install

I have tried that as well but I am getting the same error "Cannot find module node-kmeans"
