Metadata + Convex

Is it possible to retrive data from convex database to use in a dynamic metadata?

I ran into a problem of useQuery hook not being able to be used in a non react function like

export async function generateMetadata({ params }: DocumentIdPageProps) {
    // eslint-disable-next-line react-hooks/rules-of-hooks
    const document = useQuery(api.documents.getById, {
        documentId: params.documentId,
    });

    if (document === undefined) {
        return {
            title: 'Loading...',
            description: 'Loading...',
        };
    }

    if (document === null) {
        return {
            title: 'Not found',
            description: 'Not found',
        };
    }

    return {
        title: document.title,
    };
}

export async function generateMetadata({ params }: DocumentIdPageProps) {
    // eslint-disable-next-line react-hooks/rules-of-hooks
    const document = useQuery(api.documents.getById, {
        documentId: params.documentId,
    });

    if (document === undefined) {
        return {
            title: 'Loading...',
            description: 'Loading...',
        };
    }

    if (document === null) {
        return {
            title: 'Not found',
            description: 'Not found',
        };
    }

    return {
        title: document.title,
    };
}

Is there a way to get data from convex without having to use a hook that can be used in outside non react functions? (without having to use an external backend) Thanks for any help!

Try this in a function called within a react app

const convexClient = useConvex();
const result = await convexClient.query(api.file.function, { args });

const convexClient = useConvex();
const result = await convexClient.query(api.file.function, { args });

Or if you're not in React at all, you can use new ConvexHttpClient

Or fetchQuery if you're in Next.js (even if you're not in Next.js you can use fetchQuery and override the url)
