Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. The Node.js package ecosystem, npm, is the largest ecosystem of open source libraries in the world.
The Node.js project is supported by the Node.js Foundation. Contributions, policies and releases are managed under an open governance model. We are also bound by a Code of Conduct.
If you need help using or installing Node.js, please use the nodejs/help issue tracker.
The Node.js project maintains multiple types of releases:
- Stable: Released from active development branches of this repository, versioned by SemVer and signed by a member of the Release Team. Code for Stable releases is organized in this repository by major version number, For example: v4.x. The major version number of Stable releases will increment every 6 months allowing for breaking changes to be introduced. This happens in April and October every year. Stable release lines beginning in October each year have a maximum support life of 8 months. Stable release lines beginning in April each year will convert to LTS (see below) after 6 months and receive further support for 30 months.
- LTS: Releases that receive Long-term Support, with a focus on stability and security. Every second Stable release line (major version) will become an LTS line and receive 18 months of Active LTS support and a further 12 months of Maintenance. LTS release lines are given alphabetically ordered codenames, beginning with v4 Argon. LTS releases are less frequent and will attempt to maintain consistent major and minor version numbers, only incrementing patch version numbers. There are no breaking changes or feature additions, except in some special circumstances. More information can be found in the LTS README.
- Nightly: Versions of code in this repository on the current Stable branch, automatically built every 24-hours where changes exist. Use with caution.
Binaries, installers, and source tarballs are available at https://nodejs.org.
Stable and LTS releases are available at https://nodejs.org/download/release/, listed under their version strings. The latest directory is an alias for the latest Stable release. The latest LTS release from an LTS line is available in the form: latest-codename. For example: https://nodejs.org/download/release/latest-argon
Nightly builds are available at https://nodejs.org/download/nightly/, listed under their version string which includes their date (in UTC time) and the commit SHA at the HEAD of the release.
API documentation is available in each release and nightly directory under docs. https://nodejs.org/api/ points to the API documentation of the latest stable version.
Stable, LTS and Nightly download directories all contain a SHASUM256.txt
file that lists the SHA checksums for each file available for
download. To check that a downloaded file matches the checksum, run
it through sha256sum
with a command such as:
$ grep node-vx.y.z.tar.gz SHASUMS256.txt | sha256sum -c -
(Where "node-vx.y.z.tar.gz" is the name of the file you have downloaded)
Additionally, Stable and LTS releases (not Nightlies) have GPG signed
copies of SHASUM256.txt files available as SHASUM256.txt.asc. You can use
gpg
to verify that the file has not been tampered with.
To verify a SHASUM256.txt.asc, you will first need to import all of the GPG keys of individuals authorized to create releases. They are listed at the bottom of this README under Release Team. Use a command such as this to import the keys:
$ gpg --keyserver pool.sks-keyservers.net \
--recv-keys DD8F2338BAE7501E3DD5AC78C273792F7D83545D
(See the bottom of this README for a full script to import active release keys)
You can then use gpg --verify SHASUMS256.txt.asc
to verify that the
file has been signed by an authorized member of the Node.js team.
Once verified, use the SHASUMS256.txt.asc file to get the checksum for the binary verification command above.

All security bugs in Node.js are taken seriously and should be reported by emailing [email protected]. This will be delivered to a subset of the project team who handle security issues. Please don't disclose security bugs publicly until they have been handled by the security team.
Your email will be acknowledged within 24 hours, and you’ll receive a more detailed response to your email within 48 hours indicating the next steps in handling your report.
The Node.js project team comprises a group of core collaborators and a sub-group that forms the Core Technical Committee (CTC) which governs the project. For more information about the governance of the Node.js project, see GOVERNANCE.md.
