This application demonstrates a simple, reusable Node.js web application based on the Express framework.

1. Install Node.js
2. cd into this project's root directory
3. Run npm install to install the app's dependencies
4. Run npm start to start the app
5. Access the running app in a browser at the URL written to the console (most likely http://localhost:6012)

This application uses a metrics tracking package to track deployments to IBM Bluemix and other Cloud Foundry platforms. The following information is sent to a Deployment Tracker service on each deployment:

• Node.js package version
• Node.js repository URL
• Application Name (application_name)
• Application GUID (application_id)
• Application instance index number (instance_index)
• Space ID (space_id) or OS username
• Application Version (application_version)
• Application URIs (application_uris)
• Cloud Foundry API (cf_api)
• Labels of bound services
• Number of instances for each bound service and associated plan information
• Metadata in the repository.yaml file

This data is collected from the package.json and repository.yaml file in the sample application and the VCAP_APPLICATION and VCAP_SERVICES environment variables in IBM Bluemix and other Cloud Foundry platforms. This data is used by IBM to track metrics around deployments of sample applications to IBM Bluemix to measure the usefulness of our examples, so that we can continuously improve the content we offer to you. Only deployments of sample applications that include code to ping the Deployment Tracker service will be tracked.

To disable tracking, comment out the following line in app.js:

require('metrics-tracker-client').track();

If you're not using tracking, you can edit the package.json file to remove the requirement for metrics-tracker-client if you like.
