The fastest way to deploy this application to Bluemix is to click the Deploy to Bluemix button below. If you prefer instead to deploy manually to Bluemix skip ahead to the next section.

Don't have a Bluemix account? If you haven't already, you'll be prompted to sign up for a Bluemix account when you click the button. Sign up, verify your email address, then return here and click the the Deploy to Bluemix button again. Your new credentials let you deploy to the platform and also to code online with Bluemix and Git. If you have questions about working in Bluemix, find answers in the Bluemix Docs.

##Build and Deploy Locally

Configure Cloud Foundry

If you haven't already:

Install the Cloud Foundry command line interface.
Follow the instructions at the above link to connect to Bluemix.
Follow the instructions at the above link to log in to Bluemix.

###Build

Note: This section is optional and only applies if you make changes to the application

To build the application, you need to use the gulp framework. The build handles the following tasks:

Collect and copy various artifacts to the build area, like fonts, styles, and imgs.
Compile all the js and jsx files into a bundle that can also execute on the browser (uses browserify).
Minify the code and deploy it into the build area.

To start the build manually, call gulp build

###Deploy

To deploy to Bluemix, simply:

$ cf push

Note: You may notice that Bluemix assigns a URL to your application containing a random word. This is defined in the manifest.yml file where the random-route key set to the value of true. This ensures that multiple people deploying this application to Bluemix do not run into naming collisions. To specify your own route, remove the random-route line from the manifest.yml file and add a host key with the unique value you would like to use for the host name.

Privacy Notice

This web application includes code to track deployments to IBM Bluemix and other Cloud Foundry platforms. The following information is sent to a Deployment Tracker service on each deployment:

Application Name (application_name)
Space ID (space_id)
Application Version (application_version)
Application URIs (application_uris)

This data is collected from the VCAP_APPLICATION environment variable 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.

Disabling Deployment Tracking

Deployment tracking can be disabled by removing the following line from server.js:

require("cf-deployment-tracker-client").track();

Once that line is removed, you may also uninstall the cf-deployment-tracker-client npm package.
