Building PCI Compliant applications using node.js

We want to build an application using node.js, which we want to integrate with a payment gateway.

My though is, we will develop another application which will be PCI compliant. So my main application doesn't need to be PCI compliant.

What are the different possible ways through which this can be achieved in node.js applications.

I found one node module - balanced.js which takes care of this issue.

Any other thoughts?
