- ⚠️ **`app/admin/page.tsx`** - Still uses Supabase client

---

## 🔄 Pattern for Remaining Updates

### Client Components (Settings, Admin)

**Before (Supabase):**
```typescript
import { createClient } from "@/lib/supabase/client"

const supabase = createClient()
const { data: { user } } = await supabase.auth.getUser()
```

**After (MySQL API):**
```typescript
// Fetch user from API
const response = await fetch('/api/user/profile', { credentials: 'include' })
const { user } = await response.json()
```

---

## 📝 Next Steps

1. **Update `app/dashboard/settings/page.tsx`**:
   - Replace `createClient()` with `fetch('/api/user/profile')`
   - Update profile updates to use `fetch('/api/user/profile', { method: 'PUT' })`

2. **Update `app/admin/page.tsx`**:
   - Replace `createClient()` with `fetch('/api/admin/profiles')`
   - Use `/api/admin/update-plan` for plan updates

3. **Remove Supabase Dependencies**:
   ```bash
   npm uninstall @supabase/ssr @supabase/supabase-js
   rm -rf lib/supabase/
   ```

4. **Update `package.json`**:
   - Ensure `mysql2`, `bcrypt`, `nodemailer` are in dependencies
   - Remove all `@supabase/*` packages

## 🧪 Testing After Updates

### Test Authentication Flow
```bash
# 1. Sign up
curl -X POST http://localhost:3000/api/auth/signup \
  -H "Content-Type: application/json" \
  -d '{"email":"test@example.com","username":"testuser","password":"password123"}'

# 2. Login
curl -X POST http://localhost:3000/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"email":"test@example.com","password":"password123"}' \
  -c cookies.txt

# 3. Get Profile
curl http://localhost:3000/api/user/profile -b cookies.txt
```

### Test Admin Functions
```bash
# Get all users (as admin)
curl http://localhost:3000/api/admin/profiles -b cookies.txt

# Update user plan
curl -X POST http://localhost:3000/api/admin/update-plan \
  -H "Content-Type: application/json" \
  -d '{"userId":1,"plan":"premium"}' \
  -b cookies.txt
```

## ⚠️ Known Issues

### TypeScript Errors
All lint errors about missing modules (`react`, `next/server`, etc.) will resolve after running:
```bash
npm install
```

These are expected until dependencies are installed.
