Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Purpose

Prepare a MERN project for production deployment with proper configuration, security hardening, and monitoring setup.

Arguments

  • --target — Deployment target (default: vercel)
  • vercel — Vercel (recommended for Next.js)
  • aws — AWS (Lambda + API Gateway or ECS)
  • docker — Docker container (self-hosted)
  • --check-only — Run pre-deployment checklist without creating files

Pre-deployment checklist (always runs)

Environment

  • [ ] All env vars documented in .env.example
  • [ ] Production env vars set in deployment platform
  • [ ] NEXTAUTH_SECRET is unique 32+ char string
  • [ ] NODE_ENV=production in production
  • [ ] No secrets in code or committed files

Database

  • [ ] MongoDB Atlas cluster created (or production DB ready)
  • [ ] Connection string uses mongodb+srv://
  • [ ] IP whitelist configured (or 0.0.0.0/0 for serverless)
  • [ ] Database user has minimal required permissions

Security

  • [ ] Security headers configured (CSP, HSTS, etc.)
  • [ ] Rate limiting enabled
  • [ ] CORS configured for production domain
  • [ ] Auth secrets rotated from development

Performance

  • [ ] Build succeeds: pnpm build
  • [ ] No TypeScript errors
  • [ ] Bundle size reasonable (check .next/analyze if concerned)
  • [ ] Images optimized

Monitoring

  • [ ] Error tracking configured (Sentry, etc.)
  • [ ] Logging configured for production
  • [ ] Health check endpoint working: /api/health

What gets created (per target)

Vercel

vercel.json           # Vercel configuration

AWS

serverless.yml        # Serverless Framework config
  or
Dockerfile           # For ECS deployment
buildspec.yml        # CodeBuild config

Docker

Dockerfile           # Multi-stage build
docker-compose.yml   # Local testing
.dockerignore        # Ignore patterns

Workflow

  1. Run pre-deployment checklist
  2. Fix any blockers found
  3. Create deployment configuration for target
  4. Verify build succeeds
  5. Document deployment steps

Output

  • Checklist results (pass/fail)
  • Files created
  • Next steps for deployment
  • Environment variables needed in production
