Add Clerk authentication - #2
Conversation
📝 WalkthroughWalkthroughThe application adds Clerk authentication with protected request middleware, conditional home-page controls, and dedicated authentication routes. It also adds Sanity schemas, Studio configurations, GROQ queries, cached server-side data access, image helpers, and environment validation. ChangesClerk authentication

🟡 Changes recommended
Multiple routes now render Clerk client components without "use client";, and the Clerk middleware is placed in proxy.ts instead of a middleware.ts file Next.js will execute.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
Adds Clerk authentication plumbing to the Vertex Next.js app, wiring Clerk UI components into the App Router and introducing middleware configuration intended to enable Clerk’s request handling.
Changes:
- Added Clerk dependency (
@clerk/nextjs) and lockfile updates. - Introduced Clerk sign-in/sign-up App Router routes and wrapped the app with
ClerkProvider. - Updated the home page header to show signed-in vs signed-out auth controls and added related CSS.

| package.json | Adds @clerk/nextjs dependency. |
| package-lock.json | Locks Clerk and transitive dependencies. |
| app/sign-up/[[...sign-up]]/page.tsx | Adds Clerk sign-up route page. |

Clerk Next.js clerkMiddleware() protect routes auth.protect default behavior official documentation
💡 Result:
The clerkMiddleware function in Clerk's Next.js SDK does not protect any routes by default [1][2]. In contrast to the legacy authMiddleware, which protected all routes by default, clerkMiddleware treats all routes as public unless explicitly configured otherwise [1][2]. Regarding the auth.protect method, its behavior depends on both the authentication status of the user and the type of request being made [3][4][5]: 1. Authenticated and Authorized: The method returns the Auth object, allowing the request to proceed [3]. 2. Authenticated but Unauthorized: If authorization parameters (such as role or permission) are provided and the user does not meet them, the method returns a 404 error [3][4][5]. 3. Unauthenticated: - For document requests (e.g., standard page loads), it redirects the user to the sign-in page [3][6][4][5]. - For non-document requests (e.g., Route Handlers, Server Actions, or API requests), it does not redirect [4]. Instead, it typically returns a 401 error or a 404 error, depending on the specific implementation context and token type [3][6][4][5]. Clerk currently recommends shifting away from using Middleware for route protection [7][6][1]. Instead, the modern best practice is to perform authentication and authorization checks as close to the resource as possible—directly within Server Components, Route Handlers, and Server Actions—using auth.protect [7][6]. Reliance on createRouteMatcher within middleware is considered deprecated [7][6][1].

Require authentication for /studio.
proxy.ts uses clerkMiddleware() without auth.protect(). Its matcher includes /studio and nested paths, but Clerk leaves these routes public by default. Protect the Studio route explicitly.

Reject empty Sanity configuration values.
NEXT_PUBLIC_SANITY_DATASET= and NEXT_PUBLIC_SANITY_PROJECT_ID= pass this check because an empty string is not undefined. The clients then initialize with invalid identifiers and fail later with less useful errors. Reject empty strings here.
Proposed fix
function assertValue<T>(v: T | undefined, errorMessage: string): T {
- if (v === undefined) {+ if (v === undefined || v === '') {
throw new Error(errorMessage)

Adds Clerk authentication to Vertex using the specified Clerk application. Includes @clerk/nextjs, ClerkProvider, Next.js proxy middleware, sign-in and sign-up routes, signed-out auth controls, signed-in UserButton, and the required Clerk matcher. clerk doctor passes. Lint passes with two pre-existing warnings; production type-check remains blocked by existing Sanity example dependencies.
