Bluemix provides a Node.js starter application as a template so that you can add your code and push the changes back to the Bluemix environment.

The Node.js starter application has files as below:

• app.js

  This file contains the server side JavaScript code for your application written using the express server package.

• public/

  This directory contains public resources of the application, that will be served up by this server

• package.json

  This file contains metadata about your application, that is used by both the npm program to install packages, but also Bluemix when it's staging your application. For more information, see: https://docs.npmjs.com/files/package.json
