Webcomponents with hybrid rendering
Improve the interaction of your inputs with forms using hybrid rendering (LightDOM and ShadowDOM)
Normally we create webcomponents that only work with lightDOM or shadowDOM, example:
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 which allows you to execute renders independent of the main one, example: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>
);
}
- 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.
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.Thanks to useRender you will be able to work together with LightDOM and shadowDOM from the scope of the webcomponent created with Atomico.
