title: Importing Node modules in TypeScript
body: <p>How can I import Node modules which reside in the node_modules folder in TypeScript?</p>
  
  <p>I get an error message (<strong>The name ''async'' does not exist in the current scope</strong>) when I try to compile the following piece of TypeScript code:</p>
  
  <pre><code>// Converted from: var async = require('async');
  import async = module('async');
  </code></pre>
