Key Takeaways

As of October 17, 2026, Node.js 24 is the latest LTS line and the default recommendation for most production applications.
Node.js 26 is Current; Node.js 22 is in Maintenance LTS. Choose by support lifecycle, dependency compatibility, and deployment requirements—not the largest version number.
Pin your tested runtime across developer machines, CI, and production, then update that pin deliberately.
NVM manages local runtimes; Docker standardizes a container environment. Neither replaces application testing or security updates.

For most production applications, use the latest tested patch of a supported Node.js LTS release. As of October 17, 2026, that means starting with Node.js 24; evaluate Node.js 26 when you need newer capabilities or are preparing your next upgrade. The official Node.js releases page distinguishes the latest LTS line from Current.

Which Node.js Version Should I Use in 2026?

Use this date-stamped comparison as a starting point, then check the official release schedule before making a deployment decision.

Release and phase on October 17, 2026	When to choose it
Node.js 24: Active LTS	The default starting point for a production application whose dependencies and deployment platform support it.
Node.js 22: Maintenance LTS	An existing application with a compatibility constraint and a scheduled migration—not the first choice for a new project.
Node.js 26: Current	Compatibility testing, evaluating newer capabilities, or a validated deployment with an appropriate upgrade plan.

Node.js 24 is scheduled to enter Maintenance LTS on October 20, 2026, with EOL on April 30, 2028. Node.js 22 reaches EOL on April 30, 2027. Node.js 26 is scheduled to enter LTS on October 28, 2026, with EOL on April 30, 2029. These schedule dates are subject to change.

Don't confuse the latest major with the latest update within your chosen major. Select a supported release line, validate its current patch release, and keep applying updates rather than freezing the runtime indefinitely.

Node.js Current vs LTS

What Is an LTS Version of Node.js?

LTS means Long Term Support: a defined maintenance commitment, not a promise of bug-free behavior. Under the policy used by recent LTS lines, Active LTS lasts roughly 12 months, followed by roughly 18 months of Maintenance LTS—about 30 months of LTS coverage.

Typical lifecycle for recent LTS lines:
Current (~6 months)
  -> Active LTS (~12 months)
  -> Maintenance LTS (~18 months)
  -> End of life

Use the official schedule for each line's exact dates.

The Node.js Release Working Group defines Active LTS as receiving selected features, fixes, and updates appropriate for that line. Maintenance LTS focuses on critical bug fixes and security updates.

What Is the Most Stable Version of Node.js?

For practical production planning, start with the newest supported LTS line that your application and hosting environment can run. LTS describes support policy; it doesn't establish that one particular patch is universally the least buggy.

Current is a supported release phase, not another name for alpha or “untested.” It can be a reasonable engineering choice when you need its capabilities, have validated your application, and can sustain the required upgrades. LTS remains the safer operational default for most teams.

The Even/Odd Rule Changes with Node.js 27

The earlier claim that Node.js switched to odd-numbered LTS releases in 2024 was incorrect. Through Node.js 26, even-numbered majors followed the LTS path, while odd-numbered majors did not.

However, don't turn that historical pattern into a permanent rule. Node.js has announced an annual release model beginning with Node.js 27, under which every major is intended to become LTS. Node.js 27 is planned to become Current in April 2027 and LTS in October 2027, following an Alpha phase.

Choose for Your Application and Deployment

Company size doesn't determine the right runtime. Your constraints do:

Deployment support: Check which Node.js majors your hosting platform, serverless runtime, or approved base images actually provide.
Dependency compatibility: Check your framework, build tools, database drivers, and native addons before changing majors.
Support runway: Set a migration deadline before your current major reaches EOL.
Upgrade capacity: Choose Current only when its benefits justify the additional validation and lifecycle management.

Installers, 32-bit Systems, and ARM

Installers and Options

For one runtime on one machine, use the official Node.js download page to select your release line, operating system, and architecture. If you maintain projects with different requirements, use a version manager instead.

A runtime installer isn't your application's dependency manager. Install application packages separately using the project's package manager and committed lockfile. Our beginner's guide to npm explains that distinction.

32-bit vs 64-bit Systems

Match the binary to your operating system and processor architecture. Don't assume a current Node.js line provides an official 32-bit binary for your platform; consult the selected release's platform matrix, such as the Node.js 24 supported-platform documentation.

On Apple Silicon, prefer the native ARM64 runtime. On Raspberry Pi, check whether the installed operating system is 32-bit or 64-bit before selecting a binary. Native addons—packages containing compiled code—must also work with your target environment.

ARM Versions and Docker

A container tag alone doesn't specify a CPU architecture. For an ARM development machine deploying to an x86-64 server, build and test the deployment target explicitly; use multi-platform images if you deploy to both. Docker's multi-platform build documentation covers platform selection and warns that emulation can be much slower than native builds.

Use NVM to Install, Switch, and Pin Node.js

Install NVM using the nvm project's installation instructions, reopen your terminal, and run these commands from your project directory:

command -v nvm
nvm install 24
nvm use 24
node -p "process.versions.node" > .nvmrc

The final command records the selected exact version in .nvmrc. Commit that file. Other developers can then install and select it with:

nvm install
nvm use

Without a version argument, those commands read .nvmrc. Updating the project runtime means deliberately changing that file and validating the new version.

These examples use nvm-sh/nvm, intended for Unix-like shells, including macOS and WSL. Native Windows users can choose the separate nvm-windows project; follow its documentation rather than assuming identical commands or file handling.

Declare Compatibility and Configure CI

An exact runtime pin and a compatibility declaration solve different problems. The pin selects your team's tested runtime; package.json's engines field declares which versions your project supports.

For an application intentionally limited to Node.js 24, merge this fragment into package.json:

{
  "engines": {
    "node": ">=24 <25"
  }
}

engines does not install or switch Node. npm's engine-strict setting defaults to false, so an engines declaration is not enforcement by itself. To reject incompatible engines during npm installation, add this to the project's .npmrc:

engine-strict=true

Configure CI explicitly too. This GitHub Actions workflow reads the committed .nvmrc using setup-node's node-version-file input. It assumes the existing project defines test and build scripts:

# .github/workflows/test.yml
name: Test
on: [push, pull_request]
permissions:
  contents: read
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v7
      - uses: actions/setup-node@v7
        with:
          node-version-file: .nvmrc
          package-manager-cache: false
      - run: node --version
      - run: npm ci
      - run: npm test
      - run: npm run build

Your deployment runtime must be configured separately. A correct CI version doesn't automatically update a hosting dashboard, server process, or container image.

Use Lockfiles and Reinstall Dependencies

After switching Node versions, start with a clean dependency installation. npm ci requires a lockfile, removes an existing node_modules directory, and fails rather than rewriting a lockfile that disagrees with package.json.

Use the equivalent frozen or immutable installation mode for your chosen package manager. Keep its version and installation configuration consistent across environments as well.

Native addons may need compatible prebuilt binaries or recompilation after a runtime change; npm's rebuild documentation describes this case. Don't copy node_modules from another operating system, architecture, or incompatible runtime into production.

Docker as a Complement to NVM

NVM selects a host runtime; Docker packages a container's userspace environment. Use either or both depending on your workflow. Our quick explanation of Docker covers the isolation model.

This application-specific Dockerfile template assumes an existing plain-JavaScript service with server.mjs, package.json, and a committed package-lock.json. It uses the official Node.js image:

# Application-specific template: adapt entry point and build steps.
FROM node:24-bookworm-slim
WORKDIR /app
COPY package.json package-lock.json ./
RUN npm ci --omit=dev
COPY --chown=node:node . .
USER node
CMD ["node", "server.mjs"]

Add a .dockerignore so local dependencies and environment files aren't copied into the image:

node_modules
.git
.env
.env.*

Copy any required non-secret installation configuration before npm ci. Applications with a compilation step need a build stage and the appropriate build dependencies, not just this runtime template.

node:24-bookworm-slim constrains the major and OS variant, but it is still a mutable tag. For reproducible releases, use a tested image digest and deliberately update it for security fixes, as described in Docker's image-pinning guidance. Avoid node:latest or node:lts when you need to prevent implicit major upgrades.

Containers don't eliminate kernel, architecture, configuration, or native-library differences. The official Node.js image documentation also distinguishes Debian's glibc from Alpine's musl; don't treat switching image families as an inconsequential size optimization.

Production Upgrade Checklist

Inventory: Identify the runtime in local development, CI, production, scheduled jobs, and deployment images.
Check compatibility: Review the target release's notes, dependency requirements, deprecated API usage, and native-addon support.
Install cleanly: Update the runtime pin, reinstall from the lockfile, and investigate installation or compilation failures.
Validate: Run tests, builds, integration checks, and representative workloads on the deployment OS and architecture.
Align: Update CI, hosting configuration, and container images together. Verify the actual deployed version.
Roll out: Deploy gradually, retain a rollback artifact, and compare errors, latency, memory, and CPU against your baseline.

Use the Node.js performance optimization guide when investigating regressions. Treat a successful build as the start of validation, not proof that production behavior is unchanged.

FAQ

Which Node.js version should I use for production?

As of October 17, 2026, use the latest tested patch of Node.js 24 for most production applications. Confirm your dependencies and deployment platform support it before rollout.

What is the difference between Node.js Current and LTS?

Current is the release phase for newer changes; LTS provides a longer maintenance commitment. Current can be appropriate for production when you need its capabilities, validate compatibility, and maintain an upgrade plan.

How can I check whether a Node.js version is still supported?

Check the official Node.js release schedule for the major version's phase and end-of-life date. The newest patch of an EOL major does not restore upstream support.

How do I specify a Node.js version for a project?

Commit an exact version in .nvmrc, declare compatibility with engines.node, and configure CI and deployment to use the selected runtime. engines alone does not switch Node or reliably enforce the version.

Does NVM work on Windows?

The nvm-sh/nvm project works in Unix-like environments, including WSL, rather than native PowerShell or Command Prompt. For native Windows, use a separate project such as nvm-windows and follow its own installation and usage documentation.
