Ionic 4 nav component WITHOUT Angular

Really loving the new ionic 4 components -- especially, NO Angular.

Issue though: I use the ion-nav like so:

navElRef.push('second-page')

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?

So, after mucking around in the Ionic Framework 4 docs for two days, I see that there's basically nothing there to explain how to do this.

But, ... its actually not that hard to implement.

Got to: https://beta.ionicframework.com/docs/api/nav/. Then inspect the element of the phone example. Find the iframe in the elements tab of Chrome dev tools (or whatever you use). Copy that src and open it in a new browser tab. Now, you can see a working example that uses no framework. You can just copy the HTML src and create your own index.html from that and it should work.

The list of making the ion-nav work is this:

Make sure to have class="plt-desktop ios" mode="ios" attrs in HTML tag (or whatever os you want)
Make sure to have included js and CSS: 'https://unpkg.com/@ionic/core@4.0.0-beta.11/dist/ionic.js' and 'https://unpkg.com/@ionic/core@4.0.0-beta.11/css/ionic.bundle.css' in HTML file
Make sure the ion-nav is wrapped inside of the ion-app tag.
add root="page-one" attr to your ion-nav signifying what web component you want to be initially shown. "page-one" is the name of your component as defined by window.customElements.define -- whatever you want it to be.
You can use an ion-nav-push component to push another page onto the nav component. But, more likely, you'll be using a router (React, Page, etc, etc) to handle this. In your specific router solution instigate the page navigation by calling the push method on the ion-nav element: something like:

document.querySelector('ion-nav').push('page-two')

You can read more about calling the navigation methods here: https://beta.ionicframework.com/docs/api/nav/

Here is an example:
