Production Deployment & Standalone Docker Builds

Deploy Next.js apps with zero-config on Vercel or containerize with output: 'standalone' for Docker.

What You Will Learn in This Lesson

  • Deploying full-stack Next.js apps to Vercel with preview environments
  • Configuring output: 'standalone' in next.config.ts for minimal Docker images
  • Managing production environment variables and database connection pools

Introduction & Core Concept

Next.js can be deployed to serverless Edge infrastructure like Vercel or packaged into self-contained container images for Kubernetes and AWS ECS.
WHY DOES THIS MATTER IN THE REAL WORLD?

Using output: 'standalone' reduces production Docker container image size from 1.2GB to under 80MB!
