Node.js
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.
Contributors are expected to act in a collaborative manner to move
the project forward. We encourage the constructive exchange of contrary
opinions and compromise. The TSC
reserves the right to limit or block contributors who repeatedly act in ways
that discourage, exhaust, or otherwise negatively affect other participants.
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,
v22.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
Release README.
Download
Binaries, installers, and source tarballs are available at
https://nodejs.org/en/download/.
Current and LTS releases
https://nodejs.org/download/release/
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-hydrogen
directory contains the latest Hydrogen (Node.js 18) release.
Nightly releases
https://nodejs.org/download/nightly/
Each directory and filename includes the version (e.g., v22.0.0),
followed by the UTC date (e.g., 20240424 for April 24, 2024),
and the short commit SHA of the HEAD of the release (e.g., ddd0a9e494).
For instance, a full directory name might look like v22.0.0-nightly20240424ddd0a9e494.
API documentation
Documentation for the latest Current release is at https://nodejs.org/api/.
Version-specific documentation is available in each release directory in the
docs subdirectory. Version-specific documentation is also at
https://nodejs.org/download/docs/.
Verifying binaries
Download directories contain a SHASUMS256.txt.asc file with SHA checksums for the
files and the releaser PGP signature.
You can get a trusted keyring from nodejs/release-keys, e.g. using curl:
curl -fsLo "/path/to/nodejs-keyring.kbx" "https://github.com/nodejs/release-keys/raw/HEAD/gpg/pubring.kbx"
Alternatively, you can import the releaser keys in your default keyring, see
Release keys for commands on how to do that.
Then, you can verify the files you've downloaded locally
(if you're using your default keyring, pass --keyring="${GNUPGHOME:-~/.gnupg}/pubring.kbx"):
curl -fsO "https://nodejs.org/dist/${VERSION}/SHASUMS256.txt.asc" \
&& gpgv --keyring="/path/to/nodejs-keyring.kbx" --output SHASUMS256.txt < SHASUMS256.txt.asc \
&& shasum --check SHASUMS256.txt --ignore-missing
