`start`

Starts REALM in the current document. realm.js calls it for you.

start(): void

<script type="module">
  import { start } from "https://cdn.jsdelivr.net/npm/@realmorg/realm@alpha/dist/index.js";

  start();
</script>

What it does

Adopts a page stylesheet: custom-element, import-element { display: none !important } and is-visible, is-hidden, repeat-list { display: contents }.
Registers <import-element>, unless something already defined that name.
Defines every <custom-element> in the document and removes it from the page.
Watches the document with a MutationObserver: <custom-element> elements added later are defined too, and custom tags are noticed for lazy imports.

Inline definitions are resolved against document.baseURI.

Safe to call more than once. Later calls do nothing.
Takes no arguments and returns nothing. Definitions are created asynchronously, and elements upgrade as their definitions arrive.
