title: npm for javascript client side code
body: <p>I was reading a document about <a href="https://npmjs.org/doc/developers.html" rel="nofollow noreferrer">npm Developer Guide</a>.<br>
  I was wondering if it is possible to write a web client application using javascript/css/html
   by using npm?<br>
  If yes,  are there some example on github?    </p>
  
  <p>For example my client web application depends on <code>requirejs, jquery, underscore and backbone</code>.<br>
  Can I use <code>npm</code> to automatically download, in the vendor directory, the latest version of <code>requirejs, jquery, underscore and backbone</code> ?<br>
  If not, are there other tools/methods to accomplish this goal? </p>
