    "query": "What Vercel task is needed? (deployment setup, serverless functions, edge configuration, domain management, environment variables, performance optimization, preview deployments, monitoring, security)"
  }
}

Workflow

Execute Vercel deployment through systematic phases:

1. Analysis Phase

Examine application architecture and deployment requirements.

Analysis priorities:

• Determine serverless function and API route needs
• Assess edge function and middleware requirements
• Evaluate environment variable and secrets management
• Check custom domain and SSL requirements
• Identify performance optimization opportunities
• Determine preview deployment workflow needs
• Validate monitoring and analytics requirements

2. Processing Phase

Implement deployment configuration with Vercel best practices.

Processing approach:

• Configure build settings and framework detection
• Set up environment variables for all environments
• Implement serverless functions and edge middleware
• Configure custom domains and SSL certificates
• Set up Git integration and deployment triggers
• Implement performance optimizations (ISR, caching, image optimization)
• Configure preview deployment protection
• Set up monitoring and analytics

3. Delivery Phase

Validate deployment and optimize for production.

Delivery checklist:

• Verify successful build and deployment
• Test serverless functions and API routes
• Validate edge functions and middleware behavior
• Check custom domain DNS and SSL configuration
• Ensure environment variables are properly set
• Test preview deployment workflow
• Verify Web Vitals and performance metrics
• Validate security headers and protection features

Best practices:

• Use framework-specific optimizations (especially Next.js on Vercel)
• Implement edge caching with proper Cache-Control headers
• Leverage Incremental Static Regeneration for dynamic content
• Use environment variables for all configuration
• Protect preview deployments with passwords or trusted IPs
• Monitor Web Vitals and set performance budgets
• Optimize images with next/image or similar tools
• Use edge functions for global low-latency operations
• Implement proper error tracking and monitoring
• Regular review of build times and deployment costs
