Verification URL Fix - Environment Variables for Vercel

Issue Fixed

• On localhost: verification links went to /verify?email=... ✅
• On Vercel: verification links went to /verify-email?email=... ❌
• Now: Both use /verify?email=... ✅

Environment Variables to Set in Vercel

Add this environment variable to your Vercel deployment:

NEXT_PUBLIC_BASE_URL=https://your-vercel-domain.vercel.app

Important: Replace your-vercel-domain.vercel.app with your actual Vercel domain.

Changes Made

1. Removed Duplicate Routes

• ❌ Deleted /app/verify-email/page.tsx
• ❌ Deleted /app/api/auth/verify-email/route.ts
• ✅ Kept only /app/verify/page.tsx and /app/api/auth/verify/route.ts

2. Added Redirect (next.config.mjs)

async redirects() {
  return [
    {
      source: '/verify-email',
      destination: '/verify',
      permanent: true
    }
  ];
},

3. Updated Email Templates

• All emails now include clickable "Verify Now" buttons
• Links point to /verify?email=...&code=...
• Works with both Resend and SMTP fallback

4. Enhanced Verify Page

• Handles code parameter from URL (auto-verification)
• Supports manual code entry
• Single source of truth for verification

5. Environment Variables Added

• Local (.env.local): NEXT_PUBLIC_BASE_URL=http://localhost:3000
• Vercel: NEXT_PUBLIC_BASE_URL=https://your-domain.vercel.app

Testing

1. Register a new user
2. Check email - should have "Verify Now" button
3. Click button - should go to /verify?email=...&code=...
4. Should auto-verify and redirect to signin
5. Works identically on localhost and Vercel

Deliverables ✅

• Email links always point to /verify?email=... in both localhost and Vercel
• Only one verification page (/verify)
• No more /verify-email (deleted + redirect added)
• Localhost and production behave identically
• Enhanced logging for debugging on Vercel
