# 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](./GOVERNANCE.md). 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](./GOVERNANCE.md#technical-steering-committee)
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][].**

## Support
Looking for help? Check out the
[instructions for getting support](.github/SUPPORT.md).
## Release types
* **Current**: Under active development. Code for the Current release is in the
branch for its major version number (for example,
[v15.x](https://github.com/nodejs/node/tree/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](https://semver.org). A
member of the Release Team [signs](#release-keys) each Current and LTS release.
For more information, see the
[Release README](https://github.com/nodejs/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](https://nodejs.org/download/release/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](https://nodejs.org/download/release/latest-fermium/) directory
contains the latest Fermium (Node.js 14) release.
#### Nightly releases
<https://nodejs.org/download/nightly/>
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 <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`:
```console
$ 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:
```console
$ 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
`SHASUMS256.txt`. You will first need to import
[the GPG keys of individuals authorized to create releases](#release-keys). To
import the keys:
```console
$ gpg --keyserver hkps://keys.openpgp.org --recv-keys 4ED778F539E3634C779C87C6D7062848A1AB005C
```
See [Release keys](#release-keys) for a script to import active release keys.
Next, download the `SHASUMS256.txt.sig` for the release:
```console
$ 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.
