# Contributing to Express

Express and the other projects in the [expressjs organization on GitHub](https://github.com/expressjs) are projects of the [OpenJs Foundation](https://openjsf.org/).
These projects are governed under the general policies and guidelines of the Node.js Foundation along with the additional guidelines below.

* [Technical committee](#technical-committee)
* [Community contributing guide](#community-contributing-guide)
* [Collaborator's guide](#collaborators-guide)
* [Security policies and procedures](#security-policies-and-procedures)

## Technical committee

The Express technical committee consists of active project members, and guides development and maintenance of the Express project. For more information, see [Express Community - Technical committee](community.html#technical-committee).

## Community contributing guide

<!-- SRC: expressjs/express Contributing.md -->

The goal of this document is to create a contribution process that:

* Encourages new contributions.
* Encourages contributors to remain involved.
* Avoids unnecessary processes and bureaucracy whenever possible.
* Creates a transparent decision making process that makes it clear how
contributors can be involved in decision making.

### Vocabulary

* A **Contributor** is any individual creating or commenting on an issue or pull request.
* A **Committer** is a subset of contributors who have been given write access to the repository.
* A **Project Captain** is the lead maintainer of a repository.
* A **TC (Technical Committee)** is a group of committers representing the required technical
expertise to resolve rare disputes.
* A **Triager** is a subset of contributors who have been given triage access to the repository.

### Logging Issues

Log an issue for any question or problem you might have. When in doubt, log an issue, and
any additional policies about what to include will be provided in the responses. The only
exception is security disclosures which should be sent privately.

Committers may direct you to another repository, ask for additional clarifications, and
add appropriate metadata before the issue is addressed.

Please be courteous and respectful. Every participant is expected to follow the
project's Code of Conduct.

### Contributions

Any change to resources in this repository must be through pull requests. This applies to all changes
to documentation, code, binary files, etc. Even long term committers and TC members must use
pull requests.

No pull request can be merged without being reviewed.

For non-trivial contributions, pull requests should sit for at least 36 hours to ensure that
contributors in other timezones have time to review. Consideration should also be given to
weekends and other holiday periods to ensure active committers all have reasonable time to
become involved in the discussion and review process if they wish.

The default for each contribution is that it is accepted once no committer has an objection.
During a review, committers may also request that a specific contributor who is most versed in a
particular area gives a "LGTM" before the PR can be merged. There is no additional "sign off"
process for contributions to land. Once all issues brought by committers are addressed it can
be landed by any committer.

In the case of an objection being raised in a pull request by another committer, all involved
committers should seek to arrive at a consensus by way of addressing concerns being expressed
by discussion, compromise on the proposed change, or withdrawal of the proposed change.

If a contribution is controversial and committers cannot agree about how to get it to land
or if it should land then it should be escalated to the TC. TC members should regularly
discuss pending contributions in order to find a resolution. It is expected that only a
small minority of issues be brought to the TC for resolution and that discussion and
compromise among committers be the default resolution mechanism.

### Becoming a Triager

Anyone can become a triager! Read more about the process of being a triager in
[the triage process document](https://github.com/expressjs/express/blob/master/Triager-Guide.md).

Currently, any existing [organization member](https://github.com/orgs/expressjs/people) can nominate
a new triager. If you are interested in becoming a triager, our best advice is to actively participate
in the community by helping triaging issues and pull requests. As well we recommend
to engage in other community activities like attending the TC meetings, and participating in the Slack
discussions.

You can also reach out to any of the [organization members](https://github.com/orgs/expressjs/people)
if you have questions or need guidance.

### Becoming a Committer

All contributors who land a non-trivial contribution should be on-boarded in a timely manner,
and added as a committer, and be given write access to the repository.

Committers are expected to follow this policy and continue to send pull requests, go through
proper review, and have other committers merge their pull requests.

### TC Process

The TC uses a "consensus seeking" process for issues that are escalated to the TC.
The group tries to find a resolution that has no open objections among TC members.
If a consensus cannot be reached that has no objections then a majority wins vote
is called. It is also expected that the majority of decisions made by the TC are via
a consensus seeking process and that voting is only used as a last-resort.

Resolution may involve returning the issue to project captains with suggestions on
how to move forward towards a consensus. It is not expected that a meeting of the TC
will resolve all issues on its agenda during that meeting and may prefer to continue
the discussion happening among the project captains.

Members can be added to the TC at any time. Any TC member can nominate another committer
to the TC and the TC uses its standard consensus seeking process to evaluate whether or
not to add this new member. The TC will consist of a minimum of 3 active members and a
maximum of 10. If the TC should drop below 5 members the active TC members should nominate
someone new. If a TC member is stepping down, they are encouraged (but not required) to
nominate someone to take their place.

TC members will be added as admin's on the Github orgs, npm orgs, and other resources as
necessary to be effective in the role.

To remain "active" a TC member should have participation within the last 12 months and miss
no more than six consecutive TC meetings. Our goal is to increase participation, not punish
people for any lack of participation, this guideline should be only be used as such
(replace an inactive member with a new active one, for example). Members who do not meet this
are expected to step down. If A TC member does not step down, an issue can be opened in the
discussions repo to move them to inactive status. TC members who step down or are removed due
to inactivity will be moved into inactive status.

Inactive status members can become active members by self nomination if the TC is not already
larger than the maximum of 10. They will also be given preference if, while at max size, an
active member steps down.

### Project Captains

The Express TC can designate captains for individual projects/repos in the
organizations. These captains are responsible for being the primary
day-to-day maintainers of the repo on a technical and community front.
Repo captains are empowered with repo ownership and package publication rights.
When there are conflicts, especially on topics that effect the Express project
at large, captains are responsible to raise it up to the TC and drive
those conflicts to resolution. Captains are also responsible for making sure
community members follow the community guidelines, maintaining the repo
and the published package, as well as in providing user support.

Like TC members, Repo captains are a subset of committers.

To become a captain for a project the candidate is expected to participate in that
project for at least 6 months as a committer prior to the request. They should have
helped with code contributions as well as triaging issues. They are also required to
have 2FA enabled on both their GitHub and npm accounts. Any TC member or existing
captain on the repo can nominate another committer to the captain role, submit a PR to
this doc, in the **Active Project Captains** section (maintaining the sort order) with
the project, their GitHub handle and npm username (if different). The PR will require
at least 2 approvals from TC members and 2 weeks hold time to allow for comment and/or
dissent.  When the PR is merged, a TC member will add them to the proper GitHub/npm groups.

## Collaborator's guide

<!-- SRC: expressjs/express Collaborator-Guide.md -->

### Website Issues

Open issues for the expressjs.com website in https://github.com/expressjs/expressjs.com.

### PRs and Code contributions

* Tests must pass.
* Follow the [JavaScript Standard Style](http://standardjs.com/) and `npm run lint`.
* If you fix a bug, add a test.

### Branches

Use the `master` branch for bug fixes or minor work that is intended for the
current release stream.

Use the correspondingly named branch, e.g. `5.0`, for anything intended for
a future release of Express.

### Steps for contributing

1. [Create an issue](https://github.com/expressjs/express/issues/new) for the
   bug you want to fix or the feature that you want to add.
2. Create your own [fork](https://github.com/expressjs/express) on GitHub, then
   checkout your fork.
3. Write your code in your local copy. It's good practice to create a branch for
   each new issue you work on, although not compulsory.
4. To run the test suite, first install the dependencies by running `npm install`,
   then run `npm test`.
5. Ensure your code is linted by running `npm run lint` -- fix any issue you
   see listed.
6. If the tests pass, you can commit your changes to your fork and then create
   a pull request from there. Make sure to reference your issue from the pull
   request comments by including the issue number e.g. `#123`.

### Issues which are questions

We will typically close any vague issues or questions that are specific to some
app you are writing. Please double check the docs and other references before
being trigger happy with posting a question issue.

Things that will help get your question issue looked at:

* Full and runnable JS code.
* Clear description of the problem or unexpected behavior.
* Clear description of the expected result.
* Steps you have taken to debug it yourself.

If you post a question and do not outline the above items or make it easy for
us to understand and reproduce your issue, it will be closed.

## Security Policies and Procedures

<!-- SRC: expressjs/express Security.md -->

This document outlines security procedures and general policies for the Express
project.

  * [Reporting a Bug](#reporting-a-bug)
  * [Disclosure Policy](#disclosure-policy)
  * [Comments on this Policy](#comments-on-this-policy)

### Reporting a Bug

The Express team and community take all security bugs in Express seriously.
Thank you for improving the security of Express. We appreciate your efforts and
responsible disclosure and will make every effort to acknowledge your
contributions.

Report security bugs by emailing the lead maintainer in the Readme.md file.

To ensure the timely response to your report, please ensure that the entirety
of the report is contained within the email body and not solely behind a web
link or an attachment.

The lead maintainer will acknowledge your email within 48 hours, and will send a
more detailed response within 48 hours indicating the next steps in handling
your report. After the initial reply to your report, the security team will
endeavor to keep you informed of the progress towards a fix and full
announcement, and may ask for additional information or guidance.

Report security bugs in third-party modules to the person or team maintaining
the module.

### Pre-release Versions

Alpha and Beta releases are unstable and **not suitable for production use**.
Vulnerabilities found in pre-releases should be reported according to the [Reporting a Bug](#reporting-a-bug) section.
Due to the unstable nature of the branch it is not guaranteed that any fixes will be released in the next pre-release.

### Disclosure Policy

When the security team receives a security bug report, they will assign it to a
primary handler. This person will coordinate the fix and release process,
involving the following steps:

  * Confirm the problem and determine the affected versions.
  * Audit code to find any potential similar problems.
  * Prepare fixes for all releases still under maintenance. These fixes will be
    released as fast as possible to npm.

### The Express Threat Model

We are currently working on a new version of the security model, the most updated version can be found [here](https://github.com/expressjs/security-wg/blob/main/docs/ThreatModel.md)

### Comments on this Policy

If you have suggestions on how this process could be improved please submit a
pull request.
