Clerk Authentication

Patterns

Next.js App Router Setup

Complete Clerk setup for Next.js 14/15 App Router.

Includes ClerkProvider, environment variables, and basic sign-in/sign-up components.

Key components:

  • ClerkProvider: Wraps app for auth context
  • , : Pre-built auth forms
  • : User menu with session management

Middleware Route Protection

Protect routes using clerkMiddleware and createRouteMatcher.

Best practices:

  • Single middleware.ts file at project root
  • Use createRouteMatcher for route groups
  • auth.protect() for explicit protection
  • Centralize all auth logic in middleware

Server Component Authentication

Access auth state in Server Components using auth() and currentUser().

Key functions:

  • auth(): Returns userId, sessionId, orgId, claims
  • currentUser(): Returns full User object
  • Both require clerkMiddleware to be configured
