README.md

Node.js

Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine. For more 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 is bound by a Code of Conduct.

Support

Release Types

  • Current: Under active development. Code for the Current release is in the branch for its major version number (for example, v10.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 18 months of Active LTS support and a further 12 months of Maintenance. LTS release lines have alphabetically-ordered codenames, 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-carbon directory contains the latest Carbon (Node.js 8) release.

Nightly Releases

https://nodejs.org/download/nightly/

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

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 file with SHA checksums for the files.

To download SHASUMS256.txt using curl:

$ curl -O https://nodejs.org/dist/vx.y.z/SHASUMS256.txt

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 -

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 SHASUM256.txt. You will first need to import the GPG keys of individuals authorized to create releases. 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.

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

$ curl -O https://nodejs.org/dist/vx.y.z/SHASUMS256.txt.sig

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

Release Keys

To import the full set of trusted release keys:
