Clerk Auth Integration for Website

Clerk is a ready-made authentication provider with UI components, session management, and built-in social logins. Suitable for Next.js, React, Remix, and other frameworks. Instead of manually implementing JWT, storing passwords, and email verification, developer gets ready stack in hours.

What's Included

  • Install @clerk/nextjs or @clerk/clerk-react, set up ClerkProvider
  • Configure OAuth providers (Google, GitHub, Apple, VK) via dashboard
  • Place <SignIn />, <SignUp />, <UserButton /> components on needed routes
  • Protect routes via authMiddleware (Next.js App Router) or withClerkMiddleware
  • Pass userId and user metadata to backend via getAuth() / currentUser()
  • Set up webhook endpoint for syncing user.created, user.updated events with database

Typical Workflow

Browser → Clerk Hosted UI → JWT (session token) → your API
                                       ↓
                              Clerk Backend SDK → token verification

On server side, token is verified via clerkClient.verifyToken() or automatically via middleware. Clerk's public key is available at JWKS endpoint — verification happens locally without network requests.

Timeline

Basic integration with email+password and one OAuth provider — 1 working day. Full setup with webhook synchronization, custom metadata, and roles — 2–3 days.
