Node.js wth Istanbul code coverage

I have installed node.js is there any help to work on node.js wth istanbul to do codecoverage

I have the same issue right now - Windows Server 2008 x64, NodeJS. In my case I am trying to launch istanbul for Jasmine testing framework, because all tests are written for it. I recommend you to follow this question, so you will be able to launch your tests and see the coverage using Mocha testing framework.
