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, begining 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.
Prerequisites:
gcc
andg++
4.8 or newer, orclang
andclang++
3.4 or newer- Python 2.6 or 2.7
- GNU Make 3.81 or newer

$ ./configure
$ make
$ [sudo] make install
If your Python binary is in a non-standard location or has a non-standard name, run the following instead:
$ export PYTHON=/path/to/python
$ $PYTHON ./configure
$ make
$ [sudo] make install
To run the tests:
$ make test
To build the documentation:
$ make doc
To read the documentation:
$ man doc/node.1
To test if Node.js was built correctly:

Prerequisites:
- Python 2.6 or 2.7
- Visual Studio 2013 for Windows Desktop, or
- Visual Studio Express 2013 for Windows Desktop
- Basic Unix tools required for some tests,
Git for Windows includes Git Bash
and tools which can be included in the global
PATH
.
> vcbuild nosign
To run the tests:
> vcbuild test
To test if Node.js was built correctly:
$ node -e "console.log('Hello from Node.js ' + process.version)"
Be sure you have downloaded and extracted [Android NDK] (https://developer.android.com/tools/sdk/ndk/index.html) before in a folder. Then run:
$ ./android-configure /path/to/your/android-ndk
$ make
Intl support is not enabled by default.
This option will build with "small" (English only) support, but
the full Intl
(ECMA-402) APIs. With --download=all
it will
download the ICU library as needed.
Unix / Macintosh:
$ ./configure --with-intl=small-icu --download=all
Windows:
> vcbuild small-icu download-all
The small-icu
mode builds with English-only data. You can add full
data at runtime.
Note: more docs are on the node wiki.
With the --download=all
, this may download ICU if you don't have an
ICU in deps/icu
.
Unix / Macintosh:
$ ./configure --with-intl=full-icu --download=all
Windows:
> vcbuild full-icu download-all
The Intl
object will not be available. This is the default at
present, so this option is not normally needed.
Unix / Macintosh:
$ ./configure --with-intl=none
Windows:
> vcbuild intl-none
$ pkg-config --modversion icu-i18n && ./configure --with-intl=system-icu
If you are cross compiling, your pkg-config
must be able to supply a path
that works for both your host and target environments.
You can find other ICU releases at
the ICU homepage.
Download the file named something like icu4c-**##.#**-src.tgz
(or
.zip
).
Unix / Macintosh
# from an already-unpacked ICU:
$ ./configure --with-intl=[small-icu,full-icu] --with-icu-source=/path/to/icu
# from a local ICU tarball
$ ./configure --with-intl=[small-icu,full-icu] --with-icu-source=/path/to/icu.tgz
# from a tarball URL
$ ./configure --with-intl=full-icu --with-icu-source=http://url/to/icu.tgz
Windows
First unpack latest ICU to deps/icu
icu4c-##.#-src.tgz (or .zip
)
as deps/icu
(You'll have: deps/icu/source/...
)
> vcbuild full-icu
NOTE: Windows is not yet supported
It is possible to build Node.js with OpenSSL FIPS module.
Note that building in this way does not allow you to claim that the runtime is FIPS 140-2 validated. Instead you can indicate that the runtime uses a validated module. See the [security policy] (http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf) page 60 for more details. In addition, the validation for the underlying module is only valid if it is deployed in accordance with its [security policy] (http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf). If you need FIPS validated cryptography it is recommended that you read both the [security policy] (http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf) and [user guide] (https://openssl.org/docs/fips/UserGuide-2.0.pdf).
Instructions:
- Obtain a copy of openssl-fips-x.x.x.tar.gz.
To comply with the security policy you must ensure the path
through which you get the file complies with the requirements
for a "secure installation" as described in section 6.6 in
the [user guide] (https://openssl.org/docs/fips/UserGuide-2.0.pdf).
For evaluation/experimentation you can simply download and verify
openssl-fips-x.x.x.tar.gz
from https://www.openssl.org/source/ - Extract source to
openssl-fips
folder andcd openssl-fips
./config
make
make install
(NOTE: to comply with the security policy you must use the exact commands in steps 3-5 without any additional options as per Appendix A in the [security policy] (http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf). The only exception is that./config no-asm
can be used in place of./config
, and the FIPSDIR environment variable may be used to specify a non-standard install folder for the validated module, as per User Guide sections 4.2.1, 4.2.2, and 4.2.3.- Get into Node.js checkout folder
./configure --openssl-fips=/path/to/openssl-fips/installdir
For example on ubuntu 12 the installation directory was /usr/local/ssl/fips-2.0- Build Node.js with
make -j
- Verify with
node -p "process.versions.openssl"
(1.0.2a-fips
)
