Onboarding

This document is an outline of the things we tell new collaborators at their onboarding session.

Onboarding session

Local setup

  • git:

    • Make sure you have whitespace=fix: git config --global --add apply.whitespace fix
    • Always create a branch in your own GitHub fork for pull requests
      • Branches in the nodejs/node repository are only for release lines
    • Add the canonical nodejs repository as upstream remote:
      • git remote add upstream git@github.com:nodejs/node.git
    • To update from upstream:
      • git checkout main
      • git fetch upstream HEAD
      • git reset --hard FETCH_HEAD
    • Make a new branch for each pull request you submit.
    • Membership: Consider making your membership in the Node.js GitHub organization public. This makes it easier to identify collaborators. Instructions on how to do that are available at Publicizing or hiding organization membership.

  • Notifications:

The project has a venue for real-time discussion:

Project goals and values

  • Collaborators are the collective owners of the project

    • The project has the goals of its contributors

  • There are some higher-level goals and values

    • Empathy towards users matters (this is in part why we onboard people)
    • Generally: try to be nice to people!
    • The best outcome is for people who come to our issue tracker to feel like they can come back again.

  • You are expected to follow and hold others accountable to the Code of Conduct.

Managing the issue tracker

  • You have (mostly) free rein; don't hesitate to close an issue if you are confident that it should be closed.

    • Be nice about closing issues! Let people know why, and that issues and pull requests can be reopened if necessary.

  • See Labels.

    • There is a bot that applies subsystem labels (for example, doc, test, assert, or buffer) so that we know what parts of the code base the pull request modifies. It is not perfect, of course. Feel free to apply relevant labels and remove irrelevant labels from pull requests and issues.
    • semver-{minor,major}:
      • If a change has the remote chance of breaking something, use the semver-major label
      • When adding a semver-* label, add a comment explaining why you're adding it. Do it right away so you don't forget!
    • Please add the author-ready label for pull requests, if applicable.

  • See Who to CC in the issue tracker.

    • This will come more naturally over time
    • For many of the teams listed there, you can ask to be added if you are interested
      • Some are WGs with some process around adding people, others are only there for notifications

  • When a discussion gets heated, you can request that other collaborators keep an eye on it by opening an issue at the private nodejs/moderation repository. Note that while that repository is not public, it can be accessed by anyone in the nodejs org, so refrain from using it to report individuals (reporting spam/bots there is fine of course).

    • This is a repository to which all members of the nodejs GitHub organization (not just collaborators on Node.js core) have access. Its contents should not be shared externally.
    • Node.js has a moderation team which you should contact when unsure about taking action in the Node.js org.
    • You can moderate non-collaborator posts yourself. Please report the moderation action taken in accordance to the moderation policy.
    • You can always refer to the full moderation policy.
    • You can contact someone in the full list of moderation team members.

Reviewing pull requests

  • The primary goal is for the codebase to improve.

  • Secondary (but not far off) is for the person submitting code to succeed. A pull request from a new contributor is an opportunity to grow the community.

  • Review a bit at a time. Do not overwhelm new contributors.

    • It is tempting to micro-optimize. Don't succumb to that temptation. We change V8 often. Techniques that provide improved performance today may be unnecessary in the future.

  • Be aware: Your opinion carries a lot of weight!

  • Nits (requests for small changes that are not essential) are fine, but try to avoid stalling the pull request.

    • Identify them as nits when you comment: Nit: change foo() to bar().
    • If they are stalling the pull request, fix them yourself on merge.

  • Insofar as possible, issues should be identified by tools rather than human reviewers. If you are leaving comments about issues that could be identified by tools but are not, consider implementing the necessary tooling.

  • Minimum wait for comments time

    • There is a minimum waiting time which we try to respect for non-trivial changes so that people who may have important input in such a distributed project are able to respond.
    • For non-trivial changes, leave the pull request open for at least 48 hours.
    • If a pull request is abandoned, check if they'd mind if you took it over (especially if it just has nits left).

  • Approving a change

    • Collaborators indicate that they have reviewed and approve of the changes in a pull request using GitHub's approval interface
    • Some people like to comment LGTM (“Looks Good To Me”)
    • You have the authority to approve any other collaborator's work.
    • You cannot approve your own pull requests.
    • When explicitly using Changes requested, show empathy – comments will usually be addressed even if you don't use it.
      • If you do, it is nice if you are available later to check whether your comments have been addressed
      • If you see that the requested changes have been made, you can clear another collaborator's Changes requested review.
      • Use Changes requested to indicate that you are considering some of your comments to block the pull request from landing.

  • What belongs in Node.js:

    • Opinions vary – it's good to have a broad collaborator base for that reason!
    • If Node.js itself needs it (due to historical reasons), then it belongs in Node.js.
      • That is to say, url is there because of http, freelist is there because of http, etc.
    • Things that cannot be done outside of core, or only with significant pain such as async_hooks.

  • Continuous Integration (CI) Testing:

    • https://ci.nodejs.org/
      • It is not automatically run. You need to start it manually.
    • Log in on CI is integrated with GitHub. Try to log in now!
    • You will be using node-test-pull-request most of the time. Go there now!
    • To get to the form to start a job, click on Build with Parameters. (If you don't see it, that probably means you are not logged in!) Click it now!
    • To start CI testing from this screen, you need to fill in two elements on the form:
      • The CERTIFY_SAFE box should be checked. By checking it, you are indicating that you have reviewed the code you are about to test and you are confident that it does not contain any malicious code. (We don't want people hijacking our CI hosts to attack other hosts on the internet, for example!)
      • The PR_ID box should be filled in with the number identifying the pull request containing the code you wish to test. For example, if the URL for the pull request is https://github.com/nodejs/node/issues/7006, then put 7006 in the PR_ID.
      • The remaining elements on the form are typically unchanged.
    • If you need help with something CI-related:
      • Use the Build WG repository to file issues for the Build WG members who maintain the CI infrastructure.

Landing pull requests

See the Collaborator Guide: Landing pull requests.

Commits in one pull request that belong to one logical change should be squashed. It is rarely the case in onboarding exercises, so this needs to be pointed out separately during the onboarding.

Exercise: Make a pull request adding yourself to the README

  • Example: https://github.com/nodejs/node/commit/6669b3857f0f43ee0296eb7ac45086cd907b9e94
    • For raw commit message: git show --format=%B 6669b3857f0f43ee0296eb7ac45086cd907b9e94
  • Collaborators are in alphabetical order by GitHub username.
  • Optionally, include your personal pronouns.
  • The PR should include an addition to the mailmap file if the email being added to the collaborator list does not match the email used for commits. Otherwise tooling will not see the collaborator as being active and may suggest removing them. See gitmailmap for information on the format of the mailmap file.
  • Add the Fixes: <collaborator-nomination-issue-url> to the commit message so that when the commit lands, the nomination issue url will be automatically closed.
  • Label your pull request with the doc, notable-change, and fast-track labels. The fast-track label should cause the Node.js GitHub bot to post a comment in the pull request asking collaborators to approve the pull request by leaving a 👍 reaction on the comment.
  • Optional: Run CI on the pull request. Use the node-test-pull-request CI task. As a convenience, you may apply the request-ci label to the pull request to have a GitHub Actions workflow start the Jenkins CI task for you.
  • After two Collaborator approvals for the change and two Collaborator approvals for fast-tracking, land the PR.
  • If there are not enough approvals within a reasonable time, consider the single approval of the onboarding TSC member sufficient, and land the pull request.
    • Be sure to add the PR-URL: <full-pr-url> and appropriate Reviewed-By: metadata.
    • @node-core/utils automates the generation of metadata and the landing process. See the documentation of git-node.
    • core-validate-commit automates the validation of commit messages. This will be run during git node land --final of the git-node command.

Final notes
