title: StrongLoop grunt task and slc controller
body: <p>How can I switch datastores depending on the current instance type?
  For example: 
  Take Instance types: PRODUCTION, TEST1, TEST2;
  I would like that my model(s) to switch from PROD_MONGO Data Store to 
  TEST1_MONGO or TEST2_MONGO stores, depending on some command line option or some grunt option, determined at runtime.</p>
  
  <p>My question is somewhat related to <a href="https://stackoverflow.com/questions/21247071/what-is-the-different-between-using-strongloops-slc-run-and-node-app-js">What is the different between using StrongLoop&#39;s &quot;slc run&quot; and &quot;node app.js&quot;</a></p>
  
  <p>In addition to changing datastore backends, I'd be quite happy to log into different destinations / files. <a href="http://docs.strongloop.com/display/public/SLC/Application+logging" rel="nofollow noreferrer">http://docs.strongloop.com/display/public/SLC/Application+logging</a></p>
  
  <p>I'd be quite happy to check how one of the many Grunt Express modules can work with my StrongLoop project. I was just hoping there is some example of doing this that I might have missed.</p>
