Clerk Multi-Environment Setup

Overview

Configure Clerk across development, staging, and production environments.

Prerequisites

Clerk account with multiple instances
Understanding of environment management
CI/CD pipeline configured

Instructions

Step 1: Create Clerk Instances

Create separate Clerk instances for each environment in the Clerk Dashboard:

myapp-dev - Development
myapp-staging - Staging
myapp-prod - Production

Step 2: Environment Configuration

# .env.development.local
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_dev_...
CLERK_SECRET_KEY=sk_test_dev_...
NEXT_PUBLIC_APP_ENV=development

# .env.staging.local
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_staging_...
CLERK_SECRET_KEY=sk_test_staging_...
NEXT_PUBLIC_APP_ENV=staging

# .env.production.local
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_live_...
CLERK_SECRET_KEY=sk_live_...
NEXT_PUBLIC_APP_ENV=production

Step 3: Environment-Aware Configuration

// lib/clerk-config.ts
type Environment = 'development' | 'staging' | 'production'

interface ClerkConfig {
  signInUrl: string
  signUpUrl: string
  afterSignInUrl: string
  afterSignUpUrl: string
  debug: boolean
}

const configs: Record<Environment, ClerkConfig> = {
  development: {
    signInUrl: '/sign-in',
    signUpUrl: '/sign-up',
    afterSignInUrl: '/dashboard',
    afterSignUpUrl: '/onboarding',
    debug: true
  },
  staging: {
    signInUrl: '/sign-in',
    signUpUrl: '/sign-up',
    afterSignInUrl: '/dashboard',
    afterSignUpUrl: '/onboarding',
    debug: true
  },
  production: {
    signInUrl: '/sign-in',
    signUpUrl: '/sign-up',
    afterSignInUrl: '/dashboard',
    afterSignUpUrl: '/onboarding',
    debug: false
  }
}

export function getClerkConfig(): ClerkConfig {
  const env = (process.env.NEXT_PUBLIC_APP_ENV as Environment) || 'development'
  return configs[env]
}

// Validate environment at startup
export function validateClerkEnvironment() {
  const pk = process.env.NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY
  const env = process.env.NEXT_PUBLIC_APP_ENV

  if (env === 'production' && pk?.startsWith('pk_test_')) {
    throw new Error('Production environment using test keys!')
  }

  if (env !== 'production' && pk?.startsWith('pk_live_')) {
    console.warn('Non-production environment using live keys')
  }
}

Step 4: ClerkProvider Configuration

// app/layout.tsx
import { ClerkProvider } from '@clerk/nextjs'
import { getClerkConfig, validateClerkEnvironment } from '@/lib/clerk-config'

// Validate on startup
validateClerkEnvironment()

export default function RootLayout({ children }) {
  const config = getClerkConfig()

  return (
    <ClerkProvider
      signInUrl={config.signInUrl}
      signUpUrl={config.signUpUrl}
      afterSignInUrl={config.afterSignInUrl}
      afterSignUpUrl={config.afterSignUpUrl}
    >
      <html>
        <body>
          {config.debug && <EnvironmentBanner />}
          {children}
        </body>
      </html>
    </ClerkProvider>
  )
}

function EnvironmentBanner() {
  const env = process.env.NEXT_PUBLIC_APP_ENV

  if (env === 'production') return null

  const colors = {
    development: 'bg-green-500',
    staging: 'bg-yellow-500'
  }

  return (
    <div className={`${colors[env]} text-white text-center text-sm py-1`}>
      {env?.toUpperCase()} ENVIRONMENT
    </div>
  )
}

Step 5: Webhook Configuration Per Environment

// app/api/webhooks/clerk/route.ts
import { headers } from 'next/headers'

const WEBHOOK_SECRETS = {
  development: process.env.CLERK_WEBHOOK_SECRET_DEV,
  staging: process.env.CLERK_WEBHOOK_SECRET_STAGING,
  production: process.env.CLERK_WEBHOOK_SECRET
}

export async function POST(req: Request) {
  const env = process.env.NEXT_PUBLIC_APP_ENV as keyof typeof WEBHOOK_SECRETS
  const WEBHOOK_SECRET = WEBHOOK_SECRETS[env]

  if (!WEBHOOK_SECRET) {
    console.error(`No webhook secret for environment: ${env}`)
    return Response.json({ error: 'Configuration error' }, { status: 500 })
  }

  // ... rest of webhook handling
}

Step 6: CI/CD Environment Promotion

# .github/workflows/deploy.yml
name: Deploy

on:
  push:
    branches: [main, staging]

jobs:
  deploy:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4

      - name: Set environment
        run: |
          if [[ "${{ github.ref }}" == "refs/heads/main" ]]; then
            echo "DEPLOY_ENV=production" >> $GITHUB_ENV
            echo "CLERK_PUBLISHABLE_KEY=${{ secrets.CLERK_PUBLISHABLE_KEY_PROD }}" >> $GITHUB_ENV
            echo "CLERK_SECRET_KEY=${{ secrets.CLERK_SECRET_KEY_PROD }}" >> $GITHUB_ENV
          else
            echo "DEPLOY_ENV=staging" >> $GITHUB_ENV
            echo "CLERK_PUBLISHABLE_KEY=${{ secrets.CLERK_PUBLISHABLE_KEY_STAGING }}" >> $GITHUB_ENV
            echo "CLERK_SECRET_KEY=${{ secrets.CLERK_SECRET_KEY_STAGING }}" >> $GITHUB_ENV
          fi

      - name: Build
        run: npm run build
        env:
          NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY: ${{ env.CLERK_PUBLISHABLE_KEY }}
          NEXT_PUBLIC_APP_ENV: ${{ env.DEPLOY_ENV }}

      - name: Deploy to Vercel
        run: vercel deploy --prod
        env:
          VERCEL_TOKEN: ${{ secrets.VERCEL_TOKEN }}

Step 7: User Data Isolation

// lib/user-sync.ts
// Ensure user data doesn't leak between environments

export async function syncUser(clerkUser: any) {
  const env = process.env.NEXT_PUBLIC_APP_ENV

  await db.user.upsert({
    where: {
      clerkId_environment: {
        clerkId: clerkUser.id,
        environment: env
      }
    },
    update: { /* ... */ },
    create: {
      clerkId: clerkUser.id,
      environment: env,
      // ... other fields
    }
  })
}

Environment Matrix

Environment	Keys	Domain	Data
Development	pk_test_dev	localhost:3000	Dev DB
Staging	pk_test_staging	staging.myapp.com	Staging DB
Production	pk_live	myapp.com	Prod DB

Output

Separate Clerk instances per environment
Environment-aware configuration
Webhook handling per environment
CI/CD pipeline configured

Best Practices

Never share keys between environments
Use test keys for non-production
Validate key/environment match at startup
Separate webhook secrets per environment
Isolate user data by environment

Error Handling

Error	Cause	Solution
Wrong environment keys	Misconfiguration	Validate at startup
Webhook signature fails	Wrong secret	Check env-specific secret
User not found	Env mismatch	Check environment isolation
