src: add helper for addons to get the event loop Add a utility functions for addons to use when they need a reference to the current event loop. Currently, `uv_default_loop()` works if the embedder is the single-threaded default node executable, but even without the presence of e.g. workers that might not really an API guarantee for when Node is embedded.

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.
This project is bound by a Code of Conduct.
Node.js contributors have limited availability to address general support questions. Please make sure you are using a currently-supported version of Node.js.
When looking for support, please first search for your question in these venues:
If you didn't find an answer in one of the venues above, you can:
GitHub issues are meant for tracking enhancements and bugs, not general support.
Remember, libre != gratis; the open source license grants you the freedom to use and modify, but not commitments of other people's time. Please be respectful, and set your expectations accordingly.
The Node.js project maintains multiple types of releases:
More information can be found in the LTS README.
Binaries, installers, and source tarballs are available at https://nodejs.org.
Current 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 Current 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.
Current, LTS and Nightly download directories all contain a SHASUMS256.txt file that lists the SHA checksums for each file available for download.
The SHASUMS256.txt can be downloaded 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 -
(Where “node-vx.y.z.tar.gz” is the name of the file you have downloaded)
Additionally, Current and LTS releases (not Nightlies) have the GPG detached signature of SHASUMS256.txt available as SHASUMS256.txt.sig. You can use gpg to verify that SHASUMS256.txt has not been tampered with.
To verify SHASUMS256.txt has not been altered, 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)
Next, download the SHASUMS256.txt.sig for the release:
$ curl -O https://nodejs.org/dist/vx.y.z/SHASUMS256.txt.sig
After downloading the appropriate SHASUMS256.txt and SHASUMS256.txt.sig files, you can then use gpg --verify SHASUMS256.txt.sig SHASUMS256.txt to verify that the file has been signed by an authorized member of the Node.js team.
Once verified, use the SHASUMS256.txt file to get the checksum for the binary verification command above.
See BUILDING.md for instructions on how to build Node.js from source. The document also contains a list of officially supported platforms.
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.
There are no hard and fast rules to determine if a bug is worth reporting as a security issue. The general rule is any issue worth reporting must allow an attacker to compromise the confidentiality, integrity or availability of the Node.js application or its system for which the attacker does not already have the capability.
To illustrate the point, here are some examples of past issues and what the Security Reponse Team thinks of them. When in doubt, however, please do send us a report nonetheless.
#14519: Internal domain function can be used to cause segfaults. Causing program termination using either the public Javascript APIs or the private bindings layer APIs requires the ability to execute arbitrary Javascript code, which is already the highest level of privilege possible.
#12141: buffer: zero fill Buffer(num) by default. The buffer constructor behaviour was documented, but found to be prone to mis-use. It has since been changed, but despite much debate, was not considered misuse prone enough to justify fixing in older release lines and breaking our API stability contract.
CVE-2016-7099: Fix invalid wildcard certificate validation check. This is a high severity defect that would allow a malicious TLS server to serve an invalid wildcard certificate for its hostname and be improperly validated by a Node.js client.
#5507: Fix a defect that makes the CacheBleed Attack possible. Many, though not all, OpenSSL vulnerabilities in the TLS/SSL protocols also effect Node.js.
CVE-2016-2216: Fix defects in HTTP header parsing for requests and responses that can allow response splitting. While the impact of this vulnerability is application and network dependent, it is remotely exploitable in the HTTP protocol.
When in doubt, please do send us a report.
The Node.js project team comprises a group of core collaborators and a sub-group that forms the Technical Steering Committee (TSC) which governs the project. For more information about the governance of the Node.js project, see GOVERNANCE.md.
Collaborators follow the COLLABORATOR_GUIDE.md in maintaining the Node.js project.
