@clerk/nextjs createRouteMatcher route pattern forward slash api/admin💡 Result:
As of July 22, 2026, the
createRouteMatcher()helper in@clerk/nextjsis deprecated [1][2][3]. Clerk now recommends protecting resources directly (e.g., within Pages, Layouts, or API Route handlers) rather than relying on Middleware-based path matching [2][3]. If you are currently usingcreateRouteMatcherand need to match the/api/adminroute and its sub-paths, the following patterns are supported [4]: 1. To match/api/adminand everything under it:'/api/admin(.*)'[2] 2. Using the path segment syntax:'/api/admin/:path*'[1] Example usage (for legacy maintenance): import { createRouteMatcher } from '@clerk/nextjs/server' const isAdminRoute = createRouteMatcher(['/api/admin(.*)']) For new implementations or migrations, Clerk advises using resource-based authorization checks [2][3]. This involves invokingauth.protect()directly within your protected server-side resources instead of checking paths inmiddleware.ts[2][3]. For more details on migrating away fromcreateRouteMatcher, refer to the official Clerk migration guide [2].Citations:

Clerk Next.js createRouteMatcher docs route patterns /api admin💡 Result:
As of July 2026, the
createRouteMatcherfunction is officially deprecated in the Clerk Next.js SDK [1][2]. It currently triggers a runtime deprecation warning, and Clerk recommends migrating toward resource-based authorization checks (such as usingauth().protect()directly within your API routes or Server Components) instead of relying on centralized middleware path matching [1][2]. If you are currently usingcreateRouteMatcheror maintaining existing implementations, the following patterns apply: Route Patterns and Syntax Clerk's route matchers support path patterns and regular expressions [3][4]. When defining paths, you can use the following conventions: - Use the:path*suffix for matching path-segment subtrees (e.g.,/admin/:path*matches/admin,/admin/users, and/admin/settings/123) [1][5]. - The legacy(.*)suffix (e.g.,/admin(.*)) is also supported but is generally discouraged in favor of the more precise:path*syntax [5]. - For API routes specifically, you would typically target them by prefixing the pattern, such as/api/admin/:path*[6]. Implementation Context In yourmiddleware.ts(orproxy.ts),createRouteMatcheris typically used to determine which routes are public or protected [7][8]. Example of protecting an admin API route: import { clerkMiddleware, createRouteMatcher } from '@clerk/nextjs/server'; const isAdminRoute = createRouteMatcher(['/api/admin/:path*']); export default clerkMiddleware(async (auth, req) => { if (isAdminRoute(req)) { await auth.protect; // Enforces authentication for matched routes } }); export const config = { matcher: [ // Ensure the middleware runs for API routes '/(api|trpc)(.)', // Standard Next.js internal/static file exclusion '/((?!_next|[^?]\.(?:html?|css|js(?!on)|jpe?g|webp|png|gif|svg|ttf|woff2?|ico|csv|docx?|xlsx?|zip|webmanifest)).*)', ], }; Critical Considerations - Middleware Limitations: Centralized middleware-based matching can diverge from how Next.js routes requests, potentially leaving some resources unintentionally exposed [2]. - Webhooks: Always ensure public API endpoints (like Stripe webhooks) are explicitly excluded from protection if they do not require user authentication [6]. - Migration: You are encouraged to review the official Clerk migration guide to transition your authentication logic to resource-based checks, which provide more granular security and better alignment with Next.js routing [1][2].Citations:

@clerk/nextjs middleware auth await auth() userId role clerkMiddleware user metadata role source💡 Result:
To retrieve user metadata and roles within your Next.js middleware using Clerk, you must first ensure that the custom metadata is included in the session token [1][2][3]. ### Step 1: Customize Session Token By default, Clerk does not include
publicMetadatain the session claims to keep the token size manageable [4]. To access this data in middleware without making additional API calls, you must customize the session token in the Clerk Dashboard: 1. Navigate to Sessions → Customize session token [1][5]. 2. Add a new claim (e.g.,metadata) that maps to your user's public metadata [1]:json { "metadata": "{{user.public_metadata}}" }### Step 2: Access in Middleware Once customized, you can access this data viasessionClaimsinside theclerkMiddlewarecallback [1][6]. You mustawaittheauth()function to retrieve the current authentication context [1][7][6].typescript // middleware.ts import { clerkMiddleware, createRouteMatcher } from '`@clerk/nextjs/server`' import { NextResponse } from 'next/server' const isAdminRoute = createRouteMatcher(['/admin(.*)']) export default clerkMiddleware(async (auth, req) => { // Await the auth() helper to get context const { sessionClaims } = await auth() // Safely access your custom metadata claim const role = sessionClaims?.metadata?.role // Example: Protect routes based on role if (isAdminRoute(req) && role !== 'admin') { return NextResponse.redirect(new URL('/', req.url)) } }) export const config = { matcher: [ '/((?!_next|[^?]*\\.(?:html?|css|js(?!on)|jpe?g|webp|png|gif|svg|ttf|woff2?|ico|csv|docx?|xlsx?|zip|webmanifest)).*)', '/(api|trpc)(.*)', ], }### Key Considerations * Awaitauth(): Alwaysawaittheauth()function when calling it inside middleware or server-side components to resolve the promise [7]. * Metadata vs. Session Claims: UsingsessionClaimsis highly performant as it avoids extra network requests [1][2][3]. If you do not wish to add the claim to the token, you would have to fetch the user object via the Clerk API (clerkClient.users.getUser), which is significantly slower and subject to rate limits [4][1]. * Security:publicMetadatacan be read on the client but only modified on the server [2][6].

Clerk docs role-based access control middleware has() auth() userId💡 Result:
In Clerk, role-based access control (RBAC) and general authorization are primarily handled using the auth helper, which returns an Auth object containing the current user's authentication and authorization state [1][2]. Key Components: 1. auth: This is the core server-side helper used to access user information and authorization tools [2][3]. When awaited, it returns an object containing the current userId, isAuthenticated status, and the has helper [4][1]. 2. userId: This property on the returned Auth object provides the ID of the currently signed-in user, which should be used to scope data or perform lookups [1][3]. 3. has: This is the recommended helper for performing authorization checks [4][5]. It accepts an object specifying the access control type—such as { role: '...' }, { permission: '...' }, { feature: '...' }, or { plan: '...' }—and returns a boolean value [4][1][5]. It is flexible and allows you to implement custom logic (e.g., returning a 403 error) when a check fails [4][5]. 4. auth.protect: For more concise route protection, you can use the protect method directly on the auth object [2][6]. It can enforce authorization by accepting the same parameters as has (e.g., auth.protect({ role: 'admin' })) [2][6]. If the user does not meet the requirements, it can automatically trigger a redirect or error [2]. Best Practices: - Authorization vs. Authentication: Use auth.userId to confirm a user is signed in (authenticated) and the has helper or auth.protect to verify their specific access rights (authorized) [4][2]. - Granularity: Clerk documentation recommends permission-based authorization over role-based authorization for greater flexibility and security [5]. - Location: While you can use auth.protect in middleware for fast-path enforcement, it is recommended to perform detailed authorization checks as close to the data source or business logic as possible (e.g., in Route Handlers or Server Actions) to ensure defense in depth [7][6]. - Limitations: When using has on the server side, note that it works with custom permissions; system permissions are not included in session token claims, so you should check for specific roles instead when dealing with system-level access [5].

Return 401 for API requests before redirecting pages.
For an unauthenticated non-public API request, Line 50 redirects first, so Lines 56-63 never run.
/api/upload-videotherefore returns a sign-in redirect instead of the declared JSON 401 response. Exclude API requests from the redirect condition or handleisApiReqfirst.Proposed fix

Fix the unawaited
requireUser()caller.
app/api/upload-image/route.ts:9calls this helper withoutawait. Since authentication now suspends at Line 8, that handler starts the Cloudinary upload before authorization succeeds or rejects; the rejection also bypasses itstry/catch. Change that call toawait requireUser()and audit other callers.🤖 Prompt for AI Agents
