The useScript hook allows you to load dynamic script tags on the page from within your react application. This is useful for things like form / video embeds where the script url may include a specific identifier.
function BlockEdit( props ) {
const { attributes } = props;
const { formId } = attributes;
const { hasLoaded, scriptElement } = useScript( `https://example.com/${formId}` );
return (
...
);
}
