title: node.js database
body: <p>I'm looking for a database to pair with a node.js app. I'm assuming a json/nosql db would be preferable to a relational DB [I can do without any json/sql impedance mismatch]. I'm considering:</p>
  
  <ul>
  <li>couchdb</li>
  <li>mongodb</li>
  <li>redis</li>
  </ul>
  
  <p>Anyone have any views / war stories re compatiability/deployability of the above with node.js? Any clear favorites?</p>
