Auth Handler

Instructions

1. API Route Protection

Standard Routes: Use withAuthRequired.

export default withAuthRequired(async (req, { session, getUser }) => { ... })

Super Admin Routes: Use withSuperAdminAuthRequired.
Cron Jobs: Use cronAuthRequired.
Defense in Depth: Do NOT rely solely on middleware. Always implement individual route protection.

2. Frontend Data Access

Client Components: Use useUser() hook (SWR).
Restriction: NEVER use useSession from next-auth/react.

3. Server-Side Data Access

Check Auth: Import auth from @/auth.
Get Plan: Use getUserPlan(session.user.id). session.user is minimal.

Reference
