I wanted to know if this method is optimal or not. Because I did not find any documentation about it.

example

a server action to get the current user information

actions/whoami.ts

"use server";

import { auth, prisma } from "@/lib/auth"; // next-auth config file

export default async function whoami(): Promis<User | null> {
    const session = await auth();

    if (!session?.user || !session.user.email) {
        return null;
    }

    const user = await prisma.user.findUnique({
        where: {
            email: session.user.email,
        },
    });

    return user;
}

use in client components:

export default function ClientPage() {
    const { data: user } = useSWR("whoami", whoami);

    console.log({ user }); // user is fully typed
    return "...";
}

use in server components:

export default async function ServerPage() {
    const user = await whoami();

    console.log({ user }); // user is fully typed
    return "...";
}
