Customize kibana to use with node.js

I'm trying to add and run kibana alongside node.js as I need to customize some modules in Kibana. I'm giving ES as datasource in the config file.
I have created a node.js project and directly added the kibana source into it and I'm trying to make change over there. I have added the config file as well to the node.js project. But it is not working
Node.js server is already running on my machine.
Kindly help me with this as I'm new to kibana and node.js.
This is the folder structure of my project.

I'm using Kibana 4.1.6

What sort of customizations are you looking to achieve? You can either create a plugin or fork the Github project entirely.
