Auto-Create Database Structure

Run the build script to create required tables:
```
chmod +x build-nocodb.sh
./build-nocodb.sh
```
This creates five tables:
- Locations - Main map data with geo-location, contact info, support levels
- Login - User authentication (email, name, admin flag)
- Settings - Admin configuration and QR codes
- Shifts - Shift scheduling and management
- Shift Signups - User shift registrations
Get Table URLs

After the script completes:
1. Login to your NocoDB instance at https://db.cmlite.org
2. Navigate to your project ("Map Viewer Project - TIMESTAMP")
3. Copy the view URLs for each table from your browser address bar
4. URLs should look like: https://db.cmlite.org/dashboard/#/nc/project-id/table-id

Update Environment with URLs

Edit your .env file and add the table URLs:

NOCODB_VIEW_URL=https://db.cmlite.org/dashboard/#/nc/pnsalzrup2zqvz8/m6g7bkzv7s1w2ur
NOCODB_LOGIN_SHEET=https://db.cmlite.org/dashboard/#/nc/pnsalzrup2zqvz8/mizyc64e4r7ppzh

Security Considerations

API tokens are kept server-side only
CORS is configured for security
Rate limiting prevents abuse
Input validation on all endpoints
Helmet.js for security headers

Troubleshooting

Locations not showing

Verify table has Geo-Location, latitude, and longitude columns
Check that coordinates are valid numbers
Ensure API token has read permissions

Cannot add locations

Verify API token has write permissions
Check browser console for errors
Ensure coordinates are within valid ranges

Connection errors

Verify NocoDB instance is accessible
Check API URL format
Confirm network connectivity

Build Script Issues

Ensure NocoDB instance is accessible
Verify API token has admin permissions
Check that the NocoDB database is clean (delete all bases before running)
