title: How can I specify multiple Node.js runtime versions in my application to deploy to Bluemix?
body: <p>In the <code>package.json</code> of my application, we can specify the node version:</p>
  
  <ol>
  <li>What is the default Node.js runtime version if I do not specify anything?</li>
  <li>Can I specify multiple node versions (say 0.10.x and 0.12.x)  when I deploy to bluemix? Or I need to deploy twice, one to each version?</li>
  </ol>
  
  <p>Thanks in advance.</p>
  
  <pre><code>"engines": {
    "node": "^0.10.*",
    "node": "^0.12.*"
  } 
  </code></pre>
  
  <p>Thanks in advance</p>
