Function defineVaporCustomElement

defineVaporCustomElement(options: any, extraOptions?: any): any
defineVaporCustomElement — create a custom element backed by Vapor rendering.

Wraps Vue 3.6.0-beta.10's defineVaporCustomElement(). The generated custom element uses Vapor's compiler-optimized rendering instead of the VDOM, giving zero-overhead DOM updates inside shadow DOM.

SSR runtime is automatically tree-shaken from the generated code (beta.10 fix).

Returns null if Vue 3.6.0-beta.10+ is not detected — check before calling customElements.define().
Parameters
- options: any
- OptionalextraOptions: any
Returns any
Example
```
import { defineVaporCustomElement } from 'vapor-chamber';
const MyEl = defineVaporCustomElement({
  props: { label: String },
  setup(props) { return () => h('span', props.label); }
});
if (MyEl) customElements.define('vc-greeting', MyEl);
```
