Lazy Loading

Using the formio.embed.js file, you can also lazy load the Javascript and CSS resources required for creating a form. This allows you to embed a form within your application without adding much size to the page load, and then once the page is loaded, a loader is shown where the form will be rendered while it is downloading the renderer resources needed to render the form. You can still use the Formio.createForm method, just like you do for the “formio.form.min.js” file, but instead you would just include the formio.embed.js file which will lazy load the form into place.

<script src=""></script>
<div id="formio"></div>
<script type="text/javascript">
    Formio.createForm(document.getElementById('formio'), '');

You can also use this within your application build by importing the renderer from @formio/js/embed instead of @formio/js as follows.

import { Formio } from '@formio/js/embed';
Formio.createForm(document.getElementById('formio'), '');
