Node.js JavaScript runtime



Node.js is an open-source, cross-platform JavaScript runtime environment.

For information on using Node.js, see the [Node.js website][].

The Node.js project uses an open governance model. The
[OpenJS Foundation][] provides support for the project.

This project has a [Code of Conduct][].

Release types

Current: Under active development. Code for the Current release is in the
  branch for its major version number (for example,
  v15.x). Node.js releases a new
  major version every 6 months, allowing for breaking changes. This happens in
  April and October every year. Releases appearing each October have a support
  life of 8 months. Releases appearing each April convert to LTS (see below)
  each October.
LTS: Releases that receive Long Term Support, with a focus on stability
  and security. Every even-numbered major version will become an LTS release.
  LTS releases receive 12 months of _Active LTS_ support and a further 18 months
  of _Maintenance_. LTS release lines have alphabetically-ordered code names,
  beginning with v4 Argon. There are no breaking changes or feature additions,
  except in some special circumstances.
Nightly: Code from the Current branch built every 24-hours when there are
  changes. Use with caution.

Current and LTS releases follow semantic versioning. A
member of the Release Team signs each Current and LTS release.
For more information, see the


Binaries, installers, and source tarballs are available at

Current and LTS releases

The latest directory is an
alias for the latest Current release. The latest-_codename_ directory is an
alias for the latest release from an LTS line. For example, the
latest-fermium directory
contains the latest Fermium (Node.js 14) release.

Nightly releases

Each directory name and filename contains a date (in UTC) and the commit
SHA at the HEAD of the release.

API documentation

Documentation for the latest Current release is at .
Version-specific documentation is available in each release directory in the
_docs_ subdirectory. Version-specific documentation is also at

Verifying binaries

Download directories contain a SHASUMS256.txt file with SHA checksums for the

To download SHASUMS256.txt using curl:

  1. ```console
  2. $ curl -O
  3. ```

To check that a downloaded file matches the checksum, run
it through sha256sum with a command such as:

  1. ```console
  2. $ grep node-vx.y.z.tar.gz SHASUMS256.txt | sha256sum -c -
  3. ```

For Current and LTS, the GPG detached signature of SHASUMS256.txt is in
SHASUMS256.txt.sig. You can use it with gpg to verify the integrity of
SHASUMS256.txt. You will first need to import
import the keys:

  1. ```console
  2. $ gpg --keyserver hkps:// --recv-keys 4ED778F539E3634C779C87C6D7062848A1AB005C
  3. ```

See Release keys for a script to import active release keys.

Next, download the SHASUMS256.txt.sig for the release:

  1. ```console
  2. $ curl -O
  3. ```

Then use gpg --verify SHASUMS256.txt.sig SHASUMS256.txt to verify
the file's signature.

Security release stewards

When possible, the commitment to take slots in the
security release steward rotation is made by companies in order
to ensure individuals who act as security stewards have the
support and recognition from their employer to be able to
prioritize security releases. Security release stewards manage security
releases on a rotation basis as outlined in the
