Self-Hosting, Standalone Output & Process Management

This lesson expands the Next.js path with an advanced topic from the official Next.js documentation. The goal is not only to memorize an option or file name, but to understand its impact on rendering, caching, security, and deployment.

After this lesson you should be able to apply the topic in a real project, choose the right boundary for it, and explain it as a reviewable engineering decision.

Core Concepts

output standalone
Docker multi-stage builds
process manager
reverse proxy
persistent caches

Practical Example

# Dockerfile
FROM node:22-alpine AS deps
WORKDIR /app
COPY package*.json ./
RUN npm ci

FROM node:22-alpine AS builder
WORKDIR /app
COPY --from=deps /app/node_modules ./node_modules
COPY . .
RUN npm run build

FROM node:22-alpine AS runner
WORKDIR /app
ENV NODE_ENV=production
COPY --from=builder /app/.next/standalone ./
COPY --from=builder /app/.next/static ./.next/static
COPY --from=builder /app/public ./public
CMD ["node", "server.js"]

This lesson is aligned with these official Next.js documentation areas: Self-hosting, deployment, and standalone output docs.

Why It Matters

In production applications, this topic affects page speed, data freshness, authorization clarity, and operational reliability after deployment.

Implementation Workflow

Decide whether the data is public or user-specific.
Choose the smallest part of the tree that needs this behavior.
Connect the example to a real route and add a small verification check.
Document the effect on caching and deployment.

Hands-on Practice

Prepare a standalone deployment with a reverse proxy and documented restart commands.

Standalone output still requires copying public assets and .next/static correctly.

Summary

Judge the implementation by how clear the decision is, whether the behavior is correct after build, and how easily it can be traced in production.
