Overview

Complete checklist to ensure your Clerk integration is production-ready. Covers environment config, security hardening, monitoring, error handling, and compliance.

Prerequisites

• Clerk integration working in development
• Production environment and domain configured
• CI/CD pipeline ready

Instructions

Step 1: Environment Configuration Checklist

pk_live_

CLERK_SECRET_KEY

sk_live_

.env.local

.gitignore

CLERK_WEBHOOK_SECRET

NEXT_PUBLIC_CLERK_SIGN_IN_URL

Step 2: Validation Script

// scripts/prod-readiness.ts
import { createClerkClient } from '@clerk/backend'

async function validateProduction() {
  const checks: { name: string; pass: boolean; detail: string }[] = []

  // 1. Live keys check
  const pk = process.env.NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY || ''
  const sk = process.env.CLERK_SECRET_KEY || ''
  checks.push({
    name: 'Live publishable key',
    pass: pk.startsWith('pk_live_'),
    detail: pk.startsWith('pk_live_') ? 'Using live key' : `Using ${pk.slice(0, 8)}... (should be pk_live_)`,
  })
  checks.push({
    name: 'Live secret key',
    pass: sk.startsWith('sk_live_'),
    detail: sk.startsWith('sk_live_') ? 'Using live key' : 'Should be sk_live_ for production',
  })

  // 2. API connectivity
  try {
    const clerk = createClerkClient({ secretKey: sk })
    await clerk.users.getUserList({ limit: 1 })
    checks.push({ name: 'API connectivity', pass: true, detail: 'Backend API reachable' })
  } catch (err: any) {
    checks.push({ name: 'API connectivity', pass: false, detail: err.message })
  }

  // 3. Webhook secret
  checks.push({
    name: 'Webhook secret configured',
    pass: !!process.env.CLERK_WEBHOOK_SECRET,
    detail: process.env.CLERK_WEBHOOK_SECRET ? 'Set' : 'CLERK_WEBHOOK_SECRET missing',
  })

  // 4. Middleware exists
  const fs = await import('fs')
  const hasMiddleware = fs.existsSync('middleware.ts') || fs.existsSync('src/middleware.ts')
  checks.push({
    name: 'Middleware present',
    pass: hasMiddleware,
    detail: hasMiddleware ? 'Found' : 'middleware.ts not found at project root',
  })

  // Print results
  console.log('\n=== Clerk Production Readiness ===\n')
  for (const check of checks) {
    const icon = check.pass ? 'PASS' : 'FAIL'
    console.log(`[${icon}] ${check.name}: ${check.detail}`)
  }

  const allPass = checks.every((c) => c.pass)
  console.log(`\nResult: ${allPass ? 'READY for production' : 'NOT READY — fix failing checks'}`)
  process.exit(allPass ? 0 : 1)
}

Step 5: Error Handling Checklist

// app/error.tsx — global error boundary with auth context
'use client'
import { useAuth } from '@clerk/nextjs'

export default function Error({ error, reset }: { error: Error; reset: () => void }) {
  const { isSignedIn } = useAuth()

  return (
    <div>
      <h2>Something went wrong</h2>
      <p>{error.message}</p>
      <button onClick={reset}>Try again</button>
      {!isSignedIn && <a href="/sign-in">Sign in</a>}
    </div>
  )
}

Step 6: Performance Checklist
