Deploying Next.js applications

Deployment Options for Next.js

Next.js can be deployed in multiple ways depending on your infrastructure needs: Vercel (managed platform by Next.js creators), Docker containers, Node.js servers, or static export.

Vercel (Recommended)

The simplest option — built by the Next.js team:

bash

# Install Vercel CLI
npm i -g vercel

# Deploy
vercel

Features:

Zero configuration
Automatic HTTPS and CDN
Edge Functions and Serverless
Preview deployments per branch
Analytics and monitoring

Docker Deployment

Standalone Output

javascript

// next.config.js
const nextConfig = {
  output: "standalone",
};

Dockerfile

dockerfile

# Multi-stage build for minimal image size
FROM node:20-alpine AS deps
WORKDIR /app
COPY package.json package-lock.json ./
RUN npm ci

FROM node:20-alpine AS builder
WORKDIR /app
COPY --from=deps /app/node_modules ./node_modules
COPY . .
RUN npm run build

FROM node:20-alpine AS runner
WORKDIR /app
ENV NODE_ENV=production

# Copy only necessary files
COPY --from=builder /app/.next/standalone ./
COPY --from=builder /app/.next/static ./.next/static
COPY --from=builder /app/public ./public

EXPOSE 3000
CMD ["node", "server.js"]

bash

docker build -t my-nextjs-app .
docker run -p 3000:3000 my-nextjs-app

Node.js Server

bash

# Build
npm run build

# Start production server
npm start
# or
node .next/standalone/server.js

Static Export

For fully static sites (no server-side features):

javascript

// next.config.js
const nextConfig = {
  output: "export",
};

bash

npm run build
# Output in /out directory — deploy to any static host
# (Netlify, GitHub Pages, S3, etc.)

Limitations of static export:

No Server Components
No SSR / ISR
No API Routes
No Middleware
No Image Optimization (without external loader)

Comparison

Platform	Best for	Features
Vercel	Full Next.js features	All features, zero config
Docker	Custom infrastructure	Full control, any cloud
Node.js	Simple VPS hosting	Direct server control
Static Export	Simple static sites	Any CDN/static host
AWS Amplify	AWS ecosystem	Good Next.js support
Cloudflare Pages	Edge-first	Edge runtime

Production Checklist

Enable reactStrictMode: true
Set proper environment variables
Configure images.remotePatterns for external images
Set up error monitoring (Sentry, etc.)
Enable compression (gzip/brotli)
Configure caching headers
Set up health check endpoint
Enable HTTPS

Important:

Vercel provides the best Next.js experience with zero configuration. For self-hosting, use output: "standalone" with Docker for minimal image sizes and full feature support. Use static export only for simple sites that don't need server features. Always test your production build locally before deploying.
