`renderToStaticMarkup` is a function that renders a Component to a static string of HTML. There's usually a method exported by frameworks named something like `renderToString`.
```js
import { renderToString } from 'xxx';
import { h, renderToString } from 'xxx';
function renderToStaticMarkup(Component, props, childHTML) {
const html = renderToString(h(Component, { ...props, innerHTML: childHTML }));

The `renderToStaticMarkup` function also supports `async/await` for render functions that return a `Promise`.
```js
import { h, renderToString } from 'xxx';
async function renderToStaticMarkup(Component, props, childHTML) {
const html = await renderToString(
h(Component, { ...props, innerHTML: childHTML })
);
return { html };
}
```
### Client Entrypoint (`client.js`)
The client entrypoint of a renderer is responsible for rehydrating static HTML (the result of `renderToStaticMarkup`) back into a fully interactive component. Its `default` export should be a `function` which accepts the host element of the Component, an `astro-root` custom element.

> If your framework supports non-destructive component hydration (as opposed to a destructive `render` method), be sure to use that! Following your framework's Server Side Rendering (SSR) guide should point you in the right direction.
