git commit -m "Update filament colors"
git push origin main

Amplify will automatically build and deploy your changes.

Admin Panel

Access the admin panel at /upadaj for:

• Managing filament inventory
• Adding/editing/deleting filaments
• Managing color definitions and pricing
• Bulk sale management

Adding New Colors

Colors can be managed through:

1. Admin Panel: Navigate to /upadaj/colors to add colors via UI
2. Code: Edit src/data/bambuLabColors.ts for frontend color display:

export const bambuLabColors: Record<string, ColorMapping> = {
  // ... existing colors
  'New Color Name': { hex: '#HEXCODE' },
};

Database Migrations

Run database migrations:

# Run all pending migrations
npm run migrate

# Clear migration history (development only)
npm run migrate:clear

API Deployment

Deploy API server updates:

# Use the deployment script
./scripts/deploy-api.sh

# Or deploy manually to EC2 instance

Troubleshooting

Color Not Showing

• Check if the color name matches exactly in the database
• Ensure color exists in colors table
• Add the color mapping to bambuLabColors.ts
• Colors are case-insensitive but spelling must match

Build Errors

• Run npm run test:build to verify build succeeds
• Check TypeScript errors with npx tsc --noEmit
• Ensure all environment variables are set

Database Connection Issues

• Verify PostgreSQL is running
• Check connection string in environment variables
• Ensure database migrations have been run
