🔧 Configuration

Supabase Connection

Your Supabase project is already configured in nine-line-portal.tsx:

const supabase = createClient(
  'https://qredqlzgqxirxndpixhz.supabase.co',
  'your_anon_key'
);

Environment Variables (Optional)

For production, use environment variables:

# .env.local
NEXT_PUBLIC_SUPABASE_URL=https://qredqlzgqxirxndpixhz.supabase.co
NEXT_PUBLIC_SUPABASE_ANON_KEY=your_key

📊 Database Schema

Core Tables

profiles

• User account information
• Automatically created on signup
• Linked to Supabase Auth

websites

• Monitored website domains
• Status, uptime, load time
• Linked to user profiles

performance_metrics

• Core Web Vitals data
• Timestamped measurements
• Historical tracking

security_metrics

• SSL certificate status
• Vulnerability counts
• Scan timestamps

monitoring_locations

• Geographic monitoring points
• Check frequencies
• Per-website configuration

See supabase-schema.sql for full schema.

🎨 Customization

Branding

Update the logo and company name:

<h1 className="text-2xl font-light text-gray-900">
  Your Company Name
</h1>

Styling

The app uses Tailwind CSS. Customize colors:

// Primary color
bg-gray-900 → bg-blue-600

// Borders
border-gray-200 → border-blue-200

Monitoring Locations

Add/remove default monitoring points in handleAddWebsite:

const defaultLocations = [
  { location: 'US-East', frequency: '1 minute' },
  { location: 'EU-West', frequency: '1 minute' },
  { location: 'Asia-Pacific', frequency: '5 minutes' },
];

🔐 Security

Row Level Security (RLS)

All tables use RLS policies:

• Users can only access their own data
• Policies are enforced at the database level
• Even compromised clients can't access other users' data

Authentication

• Passwords hashed with bcrypt
• JWT tokens for session management
• Automatic token refresh
• Secure cookie storage

API Keys

The anon key is safe to expose because:

• RLS policies protect all data
• Users must authenticate to access data
• Database enforces all security rules

📈 Deployment

Vercel (Recommended)

npm install -g vercel
vercel

Netlify

npm install -g netlify-cli
netlify deploy

Manual Deployment

npm run build
# Deploy the 'out' or '.next' directory

🧪 Testing

Test Account Flow

1. Sign up: test@yourdomain.com / password123
2. Add website: example.com
3. View metrics and details
4. Logout and login again
5. Verify data persistence

Database Verification

-- Check user was created
SELECT * FROM profiles;

-- Check website was added
SELECT * FROM websites;

-- Verify RLS is working
-- (try to query as different user)

🐛 Troubleshooting

Common Issues

"relation does not exist"

• Run the SQL schema in Supabase

Authentication fails

• Check email provider is enabled in Supabase Auth

Can't see websites

• Verify RLS policies are set up
• Check browser console for errors

Slow performance

• Add database indexes (included in schema)
• Consider pagination for 100+ websites

See SETUP.md for more troubleshooting tips.
