Deployment Strategies with Vercel: Preview Deployments, Edge Functions, and Monitoring

Vercel provides the best deployment experience for Next.js. Master its features for production-grade deployments.

Preview Deployments

Every git branch gets a unique URL for testing:

// vercel.json
{
  "framework": "nextjs",
  "buildCommand": "npm run build",
  "outputDirectory": ".next",
  "regions": ["iad1", "sfo1", "lhr1"]
}

Edge Functions

// app/api/edge/route.ts (runtime: 'edge')
export const runtime = 'edge'

export async function GET(req: Request) {
  const country = req.headers.get('x-vercel-ip-country') || 'US'
  return Response.json({ country, timestamp: Date.now() })
}

Environment Management

// Use .env.local for local development
// Set production env vars in Vercel dashboard
// Use Vercel CLI for env management:
// vercel env add DATABASE_URL production
// vercel env pull .env.local

Monitoring and Analytics

Use Vercel Analytics for Web Vitals, Speed Insights for performance, and Logs for debugging.
