Node.js Production

Essential Git commands for everyday development — clone, commit, push, pull, and branch management.

Last Updated: May 2, 2026

Node.js production patterns: clustering, graceful shutdown, health checks, structured logging with pino, memory management, and Docker optimization.

Clustering & Process Management

Approach	Details
Built-in cluster	`const cluster = require('cluster'); cluster.fork()`
PM2	`pm2 start app.js -i max`
Worker threads	`new Worker('./heavy-task.js')`

SIGTERM handler

process.on('SIGTERM', () => server.close(...))

Kubernetes

Set terminationGracePeriodSeconds to match Node timeout.

pino()

Fastest Node logger — JSON output, child loggers for request context.

pino-pretty

Development only — never in production.

Technique	Benefit
`node:22-alpine`	Smallest image (~50MB)
Multi-stage builds	Copy only production artifacts
`.dockerignore`	Exclude node_modules, .git

Pro Tip: Set up /health endpoint verifying DB and cache — Kubernetes uses this for readiness probes.
