Server Authentication

Usage in Server Components

You can now call getCurrentUser() in any server component to get the current authenticated user:

import {getCurrentUser} from "@/lib/session";

const currentUser = await getCurrentUser();
if (!currentUser) {
  // handle unauthenticated state
}
console.log(currentUser.role, currentUser.subscription);

Content of getCurrentUser Function

It's a cached async function to retrieve the current user:

export const getCurrentUser = cache(async () => {
  const tokens = await getTokens(await cookies(), authConfig);
  if (!tokens) return null;

  const user = toUser(tokens);

  const db = getFirestore(getFirebaseAdminApp());
  const snapshot = await db
    .collection('users')
    .doc(user.uid)
    .get();

  const userSubscription = await getUserSubscriptionPlanById(user.uid);

  if (snapshot.exists) {
    const data = snapshot.data();
    user.role = data?.role;
    user.subscription = userSubscription;
  }

  return user;
});

This function:

Retrieves authentication tokens from cookies.
Converts the tokens to a user object.
Fetches additional user data from Firestore.
Loads the user's subscription plan.
Returns the complete user object, or null if the user is not authenticated.

For more advanced server-side authentication patterns and middleware options, refer to the next-firebase-auth-edge documentation. This will help you customize authentication and token handling according to your app's needs.

Client auth Data fetching

import {getCurrentUser} from "@/lib/session"; const currentUser = await getCurrentUser(); if (!currentUser) { // handle unauthenticated state } console.log(currentUser.role, currentUser.subscription);

export const getCurrentUser = cache(async () => { const tokens = await getTokens(await cookies(), authConfig); if (!tokens) return null; const user = toUser(tokens); const db = getFirestore(getFirebaseAdminApp()); const snapshot = await db .collection('users') .doc(user.uid) .get(); const userSubscription = await getUserSubscriptionPlanById(user.uid); if (snapshot.exists) { const data = snapshot.data(); user.role = data?.role; user.subscription = userSubscription; } return user; });
