# 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 - <SignIn />, <SignUp />: Pre-built auth forms - <UserButton />: 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 ## ⚠️ Sharp Edges | Issue | Severity | Solution | |-------|----------|----------| | Issue | critical | See docs | | Issue | high | See docs | | Issue | high | See docs | | Issue | high | See docs | | Issue | medium | See docs | | Issue | medium | See docs | | Issue | medium | See docs | | Issue | medium | See docs | ## When to Use This skill is applicable to execute the workflow or actions described in the overview.
