## 🔄 Remaining Work

### **Frontend Pages** (Need Manual Review)

The following pages may still reference Supabase and need to be updated to use API calls:

1. **`app/admin/page.tsx`** - Admin dashboard
2. **`app/auth/login/page.tsx`** - Login page
3. **`app/auth/sign-up/page.tsx`** - Signup page
4. **`app/auth/verify/page.tsx`** - Email verification
5. **`app/auth/error/page.tsx`** - Auth error page
6. **`app/dashboard/billing/page.tsx`** - Billing page
7. **`app/dashboard/settings/page.tsx`** - Settings page

**Action Required**: Update these pages to:
- Remove `import { createClient } from '@/lib/supabase/client'`
- Use `fetch('/api/user/profile')` instead of `supabase.auth.getUser()`
- Use API endpoints for all data fetching

### **Components** (Need Manual Review)

Search for Supabase usage in components:
```bash
grep -r "supabase" components/ --include="*.tsx"
```

Update any components that use Supabase client.

- `@types/nodemailer` - TypeScript types

### 2. Set Up Database

Follow `DATABASE_SETUP.md`:
1. Create MySQL database in Namecheap cPanel
2. Import `database/schema.sql`
3. Verify all 6 tables created

### 3. Configure Environment

Copy and configure `.env`:
```bash
cp .env.example .env
```

Required variables:
- MySQL credentials
- SMTP email settings
- Stripe API keys
- OpenAI API key
- Session secret

## 🗑️ Cleanup

After confirming everything works, remove old Supabase files:

```bash
# Remove Supabase utilities
rm -rf lib/supabase/

# Remove from package.json
npm uninstall @supabase/ssr @supabase/supabase-js
```

---

## ⚠️ Known Issues

### TypeScript Errors

You'll see lint errors about missing modules until you run `npm install`:
- `Cannot find module 'next/server'`
- `Cannot find module 'mysql2'`
- `Cannot find module 'bcrypt'`
- `Cannot find module 'nodemailer'`

**Solution**: Run `npm install` to install all dependencies.

### Environment Variables

The app uses `NEXT_PUBLIC_APP_URL` instead of `NEXT_PUBLIC_SITE_URL` in some places. Both should work, but for consistency:
- Use `NEXT_PUBLIC_APP_URL=https://rebrandlyai.com`
