title: Ionic 4 nav component WITHOUT Angular
body: <p>Really loving the new ionic 4 components -- especially, NO Angular. </p>
  
  <p>Issue though: I use the ion-nav like so:</p>
  
  <pre><code>navElRef.push('second-page')
  </code></pre>
  
  <p>The animation is not right. It seems I'm not setting the right parameters or classname or something. Is there docs/advice on how to use Ionic 4 nav WITHOUT angular?</p>
