# Webcomponents with hybrid rendering

Normally we create webcomponents that only work with lightDOM or shadowDOM, example:

```jsx
function componentWithLightDom() {
  return (
    <host>
      <h1>I am in the lightDOM</h1>
    </host>
  );
}

function componentWithShadowDom() {
  return (
    <host shadowDom>
      <h1>I am inside the shadowDOM</h1>
    </host>
  );
}
```

With atomico you can go further thanks to the hook [`@atomico/hooks/use-render`](https://atomico.gitbook.io/doc/packages/atomico-hooks/use-render) which allows you to execute renders independent of the main one, example:

```jsx
import { useRender } from "@atomico/hooks/use-render";

function componentWithLightDomAndShadowDom() {
  useRender(() => <h1>I am in the lightDOM</h1>);
  return (
    <host shadowDom>
      <h1>I am inside the shadowDOM</h1>
    </host>
  );
}
```

### What are the benefits of using useRender?

1. Encapsulate DOM fragments within custom Hooks and then render to any webcomponent.
2. patch the limitations of webcomponents that use shadowDOM, to improve communication with forms.

### Patch the limitations of web components that use shadow DOM, to improve communication with forms

```jsx
import { css, useProp } from "atomico";
import { useRender } from "@atomico/hooks/use-render";

function componentWithLightDomAndShadowDom(props) {
  const [value, setValue] = useProp("value");

  useRender(() => (
    <input {...props} oninput={({ target }) => setValue(target.value)} />
  ));

  return (
    <host shadowDom>
      <slot />
    </host>
  );
}

componentWithLightDomAndShadowDom.props = {
  type: {
    type: String,
    reflect: true,
    value: "text",
  },
  value: String,
};

componentWithLightDomAndShadowDom.styles = css`
  ::slotted([type="text"]) {
    border: 1px solid black;
  }
  ::slotted([type="checked"]) {
    width: 30px;
    height: 30px;
    border: 1px solid black;
  }
`;
```

With the `useRender(...)` fragment we are managing to render an input in the lightDOM, thanks to this we will be able to control said input from inside the webcomponent.

### Conclucion

Thanks to useRender you will be able to work together with LightDOM and shadowDOM from the scope of the webcomponent created with Atomico.
