title: What is the TypeScript 2.0 / ES2015 way to import assert from Node.js?
body: <p>I'm running TypeScript 2.0.3, configured to with <code>"target": "es2015",</code>.  I started with</p>
  
  <pre><code>/// &lt;reference path="../../node_modules/@types/node/index.d.ts" /&gt;
  import assert = require('assert');
  </code></pre>
  
  <p>But in Visual Studio, that gets flagged with a tooltip saying <code>Import with 'require' cannot be used when targeting ECMAScript 6 or higher.</code> I then tried:</p>
  
  <pre><code>/// &lt;reference path="../../node_modules/@types/node/index.d.ts" /&gt;
  import {assert} from 'assert';
  </code></pre>
  
  <p>Which generates <code>Error TS2305 Module '"assert"' has no exported member 'assert'.</code></p>
  
  <p>I've also tried:</p>
  
  <pre><code>/// &lt;reference path="../../node_modules/@types/node/index.d.ts" /&gt;
  import assert from 'assert';
  </code></pre>
  
  <p>Which generates <code>Error TS1192 Module '"assert"' has no default export.</code></p>
