title: Error importing firebase-admin
body: <p>I was trying to create custom tokens using the Firebase Admin SDK. But while importing <code>import * as admin from 'firebase-admin';</code> as shown <a href="https://firebase.google.com/docs/admin/setup" rel="nofollow noreferrer">here</a>. </p>
  
  <p>I got an error <code>process.binding is not supported</code>.</p>
  
  <p>I'm using </p>
  
  <ul>
  <li><code>browserify</code>: <code>14.0.0</code></li>
  <li><code>firebase</code>: <code>^3.6.8</code></li>
  <li><code>firebase-admin</code>: <code>^4.1.0</code>  </li>
  </ul>
