Ports the Clerk with Next.js guide to Prisma ORM 8, Next.js 16, and the current Clerk SDK, and adds the Prisma Compute deployment at the end. The Prisma ORM 7 version moves to /guides/v7/authentication/clerk/nextjs unchanged, following the pattern in Writing guides.

Why

Clerk reviewed the guide and asked for three corrections, and the page still carried the "This guide uses Prisma ORM 7" banner. The rest of the page was also out of date for Prisma ORM 8 (Prisma Client, prisma generate, findUnique) and for Clerk's current SDK (SignedIn/SignedOut no longer exist in @clerk/nextjs 7).

What changed

Clerk's requested corrections

  • middleware.ts is now src/proxy.ts with the same clerkMiddleware() export and the matcher from Clerk's current quickstart (Next.js 16 renamed the file convention; a note covers Next.js 15 and older).
  • <SignedIn> and <SignedOut> are replaced by <Show when="signed-in"> and <Show when="signed-out">.
  • The webhook step links straight to dashboard.clerk.com/~/webhooks instead of describing the dashboard navigation.

Prisma ORM 8

  • The project is scaffolded with create-prisma --template next, the models live in src/prisma/contract.prisma, and queries use db.orm.public.User / db.orm.public.Post (.where().first(), .create(), .upsert({ conflictOn }), .orderBy((p) => p.createdAt.desc())).
  • The reader replaces the template's migration with npx prisma migration plan --name init before db:init. Without a committed migration path the Compute deploy fails with MIGRATION_PATH_NOT_FOUND, which is now a documented gotcha.

Webhook handler

  • Verification failures and event processing are separated so a handler bug cannot be reported as a bad signature.
  • The user's primary email is used, and a verified event without an email returns 200 and is skipped. Clerk's "Send Example" payload has an empty email_addresses list, which made the old handler throw.
  • The upsert conflicts on email and updates clerkId, so a redelivered event is a no-op and a user deleted in Clerk and re-created with the same email does not fail on the unique constraint.

Secrets

  • Clerk keys go in .env.local, not .env: with output: "standalone", next build copies .env into the build output that the Compute deploy uploads. The template's .gitignore only lists .env, so the guide adds .env.local to it. The dev server reloads .env.local on save, so no restart step.

Deployment

  • New step 8 deploys to Prisma Compute with npx prisma deploy module.ts, registers a second Clerk webhook endpoint for the live URL, adds CLERK_SECRET_KEY and CLERK_WEBHOOK_SIGNING_SECRET with prisma project env add (values read from the environment), and redeploys. A note covers the publishable key for deploy-on-push builds.

Navigation

  • guides/v7/authentication/** added with meta.json files, listed in guides/v7/meta.json and /guides/v7; /guides gains an Authentication card and the "Still on Prisma ORM 7" paragraph no longer counts Clerk.

Validation

Sandbox and checks

Built from scratch and run end to end on 2026-10-19 with create-prisma@0.14.3 (prisma@8.0.0-rc.21, @prisma/orm-postgres@8.0.0-rc.16, next@16.4.0), @clerk/nextjs@7.9.17, Node.js 24.11.1, and a create-db Prisma Postgres database.

Local:

  • Signed out: GET / renders "Sign in to post", POST /api/posts returns 401, an unsigned POST /api/webhooks/clerk returns 400.
  • Clerk's example user.created delivery shows Succeeded in the dashboard and is logged by the handler.
  • Sign-up through the modal (email code) delivers user.created, the row is written, the page shows the form, and a post created through the form is listed. Rows confirmed with a direct query.
  • npx tsc --noEmit, eslint src, and next build pass.
  • The final guide text was validated by scaffolding a fresh project and applying only the commands and code blocks extracted from the page: migration plan, db:init, type check, build (no .env* in the standalone output), migration status up to date, and the signed-out smoke tests all pass. Every titled code block is byte-identical to the sandbox source.

Prisma Compute:

  • Deployed with npx prisma deploy module.ts; live URL https://hvu134ghoxhyiucxucgpswso.ewr.prisma.build (development Clerk instance, so sign-up works there; the row lands in the database the deploy provisioned).
  • The production endpoint's example delivery verifies after project env add + redeploy; sign-up, sign-out, sign-in, and post creation on the live URL were checked in the browser, including after the final build that ships no .env (so the secret key comes only from the Compute variable).

Repo checks: pnpm lint:links (0 errors), pnpm --filter docs lint:spellcheck (0 issues; authtoken added to cspell.json), pnpm --filter docs types:check, plus the docs skill scripts (check-plain.sh, check-staccato.py, check-ai-signs.sh) on the page. Two cold-reader review rounds and one technical review (installed type definitions, Clerk and Next.js docs, Compute artifact contents) were run and their findings folded in.

Not run as written: the ngrok http 3000 command. The ngrok account on the test machine could not start a session, so the local webhook step was validated through an equivalent cloudflared quick tunnel. The Clerk-facing steps (endpoint URL, signing secret, test delivery, real delivery) are identical.

Follow-up commit (review round 1)

  • Compute secrets are read with read -rs and passed to project env add by name, so no value appears on a command line or in shell history (CodeRabbit).
  • Prisma ORM 7 twin: @clerk/nextjs pinned to @6 because version 7 removed SignedIn/SignedOut; formatter {" "} artifacts and diff markers inside JSX removed so the copy button copies valid code; import-alias prompt Markdown fixed; the webhook no longer stores "null null" as a name. The twin was otherwise left as it was and has not been re-run.
  • .github/workflows/lychee.yml excludes dashboard.clerk.com/~/: Clerk's ~ shortcut resolves to the signed-in user's application and returns 404 to the link checker. The link is the one Clerk asked for.

Follow-up commit (review round 2)

  • The post form only clears its fields and reloads when the API returned 2xx, in both guides (CodeRabbit).

The Prisma 7 guide can fail to synchronize some Clerk users, and the Prisma 8 setup explanation can mislead readers about environment loading; these should be corrected before merging.

`CLERK_SECRET_KEY` and `CLERK_WEBHOOK_SIGNING_SECRET`.

- Line 40: Update the import-alias prompt text so `@/*` appears intact inside
inline code, with a space before “by default,” and close the italicized question
before the `No` response. Locate the prompt in the Clerk Next.js authentication
guide and preserve its wording.
- Around line 149-156: Update the Clerk imports and Navbar in the Next.js
authentication guide to replace SignedIn and SignedOut with Show, using the
signed-in and signed-out conditions to preserve the existing button visibility.
Apply the same change to the other affected Navbar instance.
- Around line 461-468: Update the Clerk webhook’s evt.data handling before
prisma.user.upsert to select the address matching primary_email_address_id and
skip the event when no primary email exists. Build the user name from only
present first_name and last_name values, using null when neither is available,
and pass these values into the upsert create branch.
- Around line 130-132: Update the ClerkProvider and button JSX examples so diff
markers use JSX comment notation rather than appearing as rendered text, and
remove formatter-added {" "} nodes; keep the Post text inside the button and
omit any marker after the closing ClerkProvider tag.

Read the Compute secrets with `read -rs` instead of inline assignments, fix the
Prisma ORM 7 twin (pin @clerk/nextjs@6, drop the formatter artifacts and diff
markers inside JSX, fix the import-alias prompt and the "null null" name), and
exclude dashboard.clerk.com/~/ from the link checker: it serves the signed-in
user's application and returns 404 anonymously.
