Clerk Install & Auth

Overview

Set up Clerk SDK and configure authentication credentials for your application.

Prerequisites

  • Node.js 18+ (Next.js, React, Express, etc.)
  • Package manager (npm, pnpm, or yarn)
  • Clerk account with API access
  • Publishable and Secret keys from Clerk dashboard

Instructions

Step 1: Install SDK

bash
# Next.js
npm install @clerk/nextjs

# React
npm install @clerk/clerk-react

# Express/Node.js
npm install @clerk/express

# Remix
npm install @clerk/remix

Step 2: Configure Environment Variables

bash
# Create .env.local file
cat >> .env.local << 'EOF'
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_...
CLERK_SECRET_KEY=sk_test_...
EOF

Step 3: Add ClerkProvider (Next.js App Router)

typescript
// app/layout.tsx
import { ClerkProvider } from '@clerk/nextjs'

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <ClerkProvider>
      <html lang="en">
        <body>{children}</body>
      </html>
    </ClerkProvider>
  )
}

Step 4: Add Middleware

typescript
// middleware.ts
import { clerkMiddleware } from '@clerk/nextjs/server'

export default clerkMiddleware()

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)(.*)',
  ],
}

Step 5: Verify Connection

typescript
import { auth } from '@clerk/nextjs/server'

export async function GET() {
  const { userId } = await auth()
  return Response.json({ authenticated: !!userId })
}

Output

  • Installed SDK package in node_modules
  • Environment variables configured in .env.local
  • ClerkProvider wrapping application
  • Middleware protecting routes

Error Handling

Error Cause Solution
Invalid API Key Incorrect or mismatched keys Verify keys in Clerk dashboard match environment
ClerkProvider Missing SDK used outside provider Wrap app root with ClerkProvider
Middleware Not Running Matcher misconfigured Check matcher regex in middleware.ts
Module Not Found Installation failed Run npm install @clerk/nextjs again

Examples

Next.js App Router Setup

typescript
// app/layout.tsx
import { ClerkProvider, SignInButton, SignedIn, SignedOut, UserButton } from '@clerk/nextjs'

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <ClerkProvider>
      <html lang="en">
        <body>
          <header>
            <SignedOut>
              <SignInButton />
            </SignedOut>
            <SignedIn>
              <UserButton />
            </SignedIn>
          </header>
          {children}
        </body>
      </html>
    </ClerkProvider>
  )
}

React SPA Setup

typescript
import { ClerkProvider } from '@clerk/clerk-react'

const PUBLISHABLE_KEY = import.meta.env.VITE_CLERK_PUBLISHABLE_KEY

function App() {
  return (
    <ClerkProvider publishableKey={PUBLISHABLE_KEY}>
      <Router />
    </ClerkProvider>
  )
}
