Production Checklist

Application Readiness

Environment Configuration

• Ensure you are using the correct environment variables for production.

API & Database Connections

• Verify Supabase is properly configured for production with correct API keys and URL.
• Review database schemas and ensure all required migrations have been applied.
• Enable read replicas if you anticipate high traffic to avoid performance bottlenecks.

Performance Optimization

CDN Integration

Use a Content Delivery Network (CDN) like Vercel to reduce latency and load times for your app. Ensure assets like images, JavaScript, and CSS are cached on edge locations.

Security Measures

HTTPS and SSL

Enforce HTTPS for all connections, ensuring data is securely transmitted. Use SSL certificates for all domains and subdomains.

Database Security

• Enable row-level security (RLS) in Supabase for fine-grained access control. (Already available in template.)
• Regularly audit and rotate API keys and tokens used by your application.

Monitoring and Logging

Error Monitoring

• Implement error tracking services such as Sentry or LogRocket to capture frontend and backend errors.
• Ensure that all NextJS error pages (e.g., 500, 404) are customized and user-friendly. (Already available in template.)

Performance Monitoring

• Use monitoring tools like Vercel Analytics and Supabase Monitoring to track metrics like response times, request throughput, and uptime.
• Set up alerts for critical issues, such as downtime or high server load.

Database Monitoring

• Monitor Supabase database performance, query efficiency, and usage patterns to ensure optimal performance.
• Set up auto-scaling for Supabase if your app’s database usage is expected to fluctuate.

User Experience (UX) and Functionality

Cross-Browser Compatibility

• Test your application on major browsers (Chrome, Firefox, Safari, Edge) to ensure consistent behavior across platforms.
• Ensure your app is mobile-responsive and performs well on different screen sizes. (Already available in template.)

Accessibility Compliance

• Follow accessibility standards (e.g., WCAG 2.1) to ensure your application is usable by all, including users with disabilities. (Already available in template.)

Backup and Disaster Recovery

Database Backups

• Set up automatic daily backups for your Supabase database and verify that backup restoration processes are working.

Disaster Recovery Plan

• Ensure you have a documented disaster recovery plan, including steps for restoring services in the event of data loss or downtime.

Scaling and Load Testing

Auto-Scaling

• Ensure auto-scaling is enabled in both Supabase and Vercel to handle traffic surges.

Load Testing

• Conduct load testing to simulate real-world traffic and ensure your application can handle peak loads without performance degradation.
