UI Toolkit


Use widgets

  1. Import required widget from named exports
  2. Pass a configuration Object to createApp function as an argument
  3. Configuration object should contain desired tag name as a key and widget descriptor object as a value. N.B.: widget name should contain at least one "-"
<script type="module"> 
  import createApp, { 
  } from '<path>';

    'my-card': Card,


<my-card title="Lorem Ipsum">
  <p>My content here...</p>

Control widgets using attributes (see widgets documentation)

Interaction with parent app

We implemented two ways to interact with parent application - one is data-based, another events-based. You will find supported data properties and handled events list in slot's documentation. Let's see how you can use it to build your app:

Data-based interface with watch/commit

If some data-based interface is documented for particular slot you may subscribe on it using watch method or publish changes using commit

<script type="module"> 
  import createApp from '<path>';

  const app = createApp();'observed', (value) => { 
    /* handle "observed" property change here */

    observed: /* Desired "observed" value here */,

Use watch('observed', (value) => { ... }) to watch observed property

Use watch('*', (all) => { ... }) or just watch((all) => { ... }) to watch all provided properties at once

Use commit({ observed: 'ABC' }) to commit values that you want to be sent to parent app.

N.B.: Only expected properties will be processed. Anything unexpected will be omitted

N.B.2: Due to security reasons this tool supports only simple values - like Strings, Numbers and Booleans (in depth too). Functions, Dates etc. will not work.

Events-based interface with listen/emit;

<script type="module"> 
  import createApp from '<path>';

  const app = createApp();

  app.emit('openDialog', {
    title: 'Lorem Ipsum',
    description: 'Dolor sit amet',

  app.listen('dialog:confirmed', () => {
    /* handle parent app dialog confirmation */
