Real-time updates

Live updates are beneficial for content editors as they can view drafts on the actual website without refreshing the page.

The <QueryListener /> component from the @datocms/astro package provides real-time page reload when content changes. It connects to DatoCMS's Real-time Updates API to receive updated query results instantly and can reconnect during network issues:

src/pages/index.astro
---
import { DATOCMS_CDA_TOKEN } from "astro:env/server";
const query = `
query HomeQuery {
blogPost { title }
}
`;
const data = await executeQuery(query, { includeDrafts: true });
---
<article>
<h1>{data.blogPost.title}</h1>
<QueryListener
token={DATOCMS_CDA_TOKEN}
includeDrafts
{query}
/>
</article>
