PrimeNG: how to 'pack' or 'build' the project after making changes?

I use primeng in my angular application. I wanted to add some functionality to one of the components so I followed the instructions (https://github.com/primefaces/primeng/wiki/Building-From-Source) and got all of my changes to work. Now I want to package it up so I can install this modified branch in my application. How do I go about doing that?

I've done this before with ng2-bootstrap by running 'npm pack' and then installing the generated tar package in my application. I tried doing the same with primeng but my project errored because the primeng.js file wasn't there. I'm assuming I need to do it a different way but I don't know how and I don't have much webpack/gulp experience.

1. Fork to your GitHub account
2. Clone package
3. Make a new branch
4. Make changes to new branch

Then run the following commands in order;

npm install - Downloads the dependencies

gulp build - Creates resource bundle for css

npm run build-prod - Which runs the build scripts.

You can then push this package to your own GitHub account and with a different branch name and run the following in your project you require the custom build:

npm install git://github.com/<user>/<project>.git#<branch>

Then whenever priming makes changes on the master you can merge them with your custom branch.
