# Node.js Core Working Groups
Node.js Core Working Groups are autonomous projects created by the
[Core Technical Committee (CTC)](https://github.com/nodejs/node/blob/master/GOVERNANCE.md#core-technical-committee).
Working Groups can be formed at any time but must be ratified by the CTC.
Once formed the work defined in the Working Group charter is the
responsibility of the WG rather than the CTC.
It is important that Working Groups are not formed pre-maturely. Working
Groups are not formed to *begin* a set of tasks but instead are formed
once that work is already underway and the contributors
think it would benefit from being done as an autonomous project.
If the work defined in a Working Group's charter is complete, the charter
should be revoked.
A Working Group's charter can be revoked either by consensus of the Working
Group's members or by a CTC vote. Once revoked, any future work that arises
becomes the responsibility of the CTC.
## Joining a WG
To find out how to join a working group, consult the GOVERNANCE.md in
the working group's repository, or in the working group's repository.
## Starting A Core Working Group
The process to start a Core Working Group is identical to [creating a
Top Level Working Group](https://github.com/nodejs/TSC/blob/master/WORKING_GROUPS.md#starting-a-wg).
## Current Working Groups
* [Addon API](#addon-api)
The website Working Group's purpose is to build and maintain a public
website for the Node.js project.
* Developing and maintaining a build and automation system for nodejs.org.
* Ensuring the site is regularly updated with changes made to Node.js, like
releases and features.
* Fostering and enabling a community of translators.
The Streams Working Group is dedicated to the support and improvement of the
Streams API as used in Node.js and the npm ecosystem. We seek to create a
composable API that solves the problem of representing multiple occurrences
of an event over time in a humane, low-overhead fashion. Improvements to the
API will be driven by the needs of the ecosystem; interoperability and
backwards compatibility with other solutions and prior versions are paramount
* Addressing stream issues on the Node.js issue tracker.
* Authoring and editing stream documentation within the Node.js project.
* Reviewing changes to stream subclasses within the Node.js project.
* Redirecting changes to streams from the Node.js project to this project.
* Assisting in the implementation of stream providers within Node.js.
* Recommending versions of `readable-stream` to be included in Node.js.
* Messaging about the future of streams to give the community advance notice of
The Build Working Group's purpose is to create and maintain a distributed
* Producing packages for all target platforms.
* Running tests.
* Running performance testing and comparisons.
* Creating and managing build-containers.
The Diagnostics Working Group's purpose is to surface a set of comprehensive,
documented, and extensible diagnostic interfaces for use by Node.js tools and
* Collaborating with V8 to integrate `v8_inspector` into Node.js.
* Collaborating with V8 to integrate `trace_event` into Node.js.
* Collaborating with Core to refine `async_wrap` and `async_hooks`.
* Maintaining and improving OS trace system integration (e.g. ETW, LTTNG, dtrace).
* Documenting diagnostic capabilities and APIs in Node.js and its components.
* Exploring opportunities and gaps, discussing feature requests, and addressing
conflicts in Node.js diagnostics.
* Fostering an ecosystem of diagnostics tools for Node.js.
The i18n Working Groups handle more than just translations. They
are endpoints for community members to collaborate with each
other in their language of choice.
Each team is organized around a common spoken language. Each
language community might then produce multiple localizations for
various project resources.
* Translating any Node.js materials they believe are relevant to their
* Reviewing processes for keeping translations up to date and of high quality.
* Managing and monitoring social media channels in their language.
* Promoting Node.js speakers for meetups and conferences in their language.
Note that the i18n Working Groups are distinct from the [Intl](#Intl) Working Group.
Each language community maintains its own membership.

The purpose of the Benchmark Working Group is to gain consensus
on an agreed set of benchmarks that can be used to:
* track and evangelize performance gains made between Node.js releases
* avoid performance regressions between releases
* Identifying 1 or more benchmarks that reflect customer usage.
Likely will need more than one to cover typical Node.js use cases
including low-latency and high concurrency
* Working to get community consensus on the list chosen
* Adding regular execution of chosen benchmarks to Node.js builds
* Tracking/publicizing performance between builds/releases
The Post-mortem Diagnostics Working Group is dedicated to the support

to be generated when needed.
* Defining and adding common structures to the dumps generated
in order to support tools that want to introspect those dumps.

documentation, both in the core API documentation, and elsewhere, such as the
Node.js website. Its intent is to work closely with the Evangelism, Website, and
Intl Working Groups to make excellent documentation available and accessible
* Defining and maintaining documentation style and content standards.
* Producing documentation in a format acceptable for the Website Working Group
* Ensuring that Node's documentation addresses a wide variety of audiences.
