Contributing

We look forward to seeing contribution to this product. The guidelines here represent our understanding on how to best to deliver value to production.

Here are the guidelines we would like everyone to follow:

Definition of Done

The Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product.

See: 1Team Definition of Done

Vault Definition of Done:

  • The code has been reviewed
  • Both internal (code) and external (user) documentation has been completed as appropriate
  • A robust infrastructure is in place to ensure support for the feature/product
  • The feature/functionality has been demo'd to users to get feedback when applicable
  • The work is traceable (e.g. Jira and Github tickets)
  • Static code analysis (e.g. linting) has been completed and results actioned as appropriate
  • The story has been verified (e.g. unit testing)
  • The story has been validated (e.g. User Acceptance Testing)
  • The pipeline is passing
  • All appropriate environments created (e.g. DEV, TEST, PROD)
  • Security and privacy maintained
  • Test cases have been expanded where we are able to
  • Integration or end-to-end testing (not ready, possible not feasible yet)
  • Basic documentation completed, but favour automation
  • Guidelines (minimal size, OS flexibility, etc) included
  • Automated security checks completed

Code of Conduct

Be open and inclusive. Please see our code of conduct.

Question or Problem?

Feel free to ask questions or for help with problems on our Microsoft Teams or Rocket.Chat channels.

Rocket.Chat link

We use GitHub issues for bug reports and feature requests, so anything else will be closed.

Found a Bug?

If you find a bug, you can help us by submitting an issue to our GitHub Repository. Even better, you can submit a Pull Request with a fix.

Missing a Feature?

You can request a new feature by submitting an issue to our GitHub Repository.

If you would like to implement a new feature, please consider the size of the change in order to determine the right steps to proceed:

  • For a Major Feature, first find or open an issue. Outline your proposal so that it can be discussed. This process allows us to better coordinate our efforts, prevent duplication of work, and help you to craft the change so that it is successfully accepted into the project.

  • Small Features can be crafted and directly submitted as a Pull Request.

Submission Guidelines

Submitting an Issue

Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.

We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it. In order to reproduce bugs, we require that you provide a minimal reproduction. Having a minimal reproducible scenario gives us a wealth of important information without going back and forth to you with additional questions.

A minimal reproduction allows us to quickly confirm a bug (or point out a coding problem) as well as confirm that we are fixing the right problem.

We require a minimal reproduction to save maintainers' time and ultimately be able to fix more bugs. Often, developers find coding problems themselves while preparing a minimal reproduction. We understand that sometimes it might be hard to extract essential bits of code from a larger codebase but we really need to isolate the problem before we can fix it.

Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you, we are going to close an issue that doesn't have enough info to be reproduced.

You can file new issues here.

Submitting a Pull Request

Before you submit your Pull Request (PR) consider the following guidelines:

  1. Search our pull requests for an open or closed PR that relates to your submission. You don't want to duplicate existing efforts.

  2. Be sure that an issue describes the problem you're fixing, or documents the design for the feature you'd like to add. Discussing the design upfront helps to ensure that we're ready to accept your work.

  3. Fork the repo.

  4. In your forked repository, make your changes in a new git branch:

    git checkout -b my-fix-branch master

  5. Create your patch, including appropriate test cases.

  6. Follow our Coding Rules.

  7. Run the full test suite, npm test, and ensure that all tests pass.

  8. Commit your changes using a descriptive commit message that follows our commit message conventions. Adherence to these conventions is necessary because release notes are generated from these messages.

    git commit --all

    Note: the optional commit -a command line option will automatically "add" and "rm" edited files.

  9. Push your branch to GitHub:

    git push origin my-fix-branch

  10. In GitHub, send a pull request to master.

Reviewing a Pull Request

Our team reserves the right not to accept pull requests from community members who haven't been good citizens of the community. Such behavior includes not following the code of conduct and applies within or outside our managed channels.

Addressing review feedback

If we ask for changes via code reviews then:

  1. Make the required updates to the code.

  2. Re-run the test suites to ensure tests are still passing.

  3. Create a fixup commit and push to your GitHub repository (this will update your Pull Request):

    git commit --all --fixup HEAD
git push

That's it! Thank you for your contribution!

Updating the commit message

A reviewer might often suggest changes to a commit message (for example, to add more context for a change or adhere to our commit message guidelines). In order to update the commit message of the last commit on your branch:

  1. Check out your branch:

    git checkout my-fix-branch

  2. Amend the last commit and modify the commit message:

    git commit --amend

  3. Push to your GitHub repository:

    git push --force-with-lease

NOTE:
If you need to update the commit message of an earlier commit, you can use git rebase in interactive mode. See the git docs for more details.

After your pull request is merged

After your pull request is merged, you can safely delete your branch and pull the changes from the main (upstream) repository:

  • Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:

    git push origin --delete my-fix-branch

  • Check out the master branch:

    git checkout master -f

  • Delete the local branch:

    git branch -D my-fix-branch

  • Update your master with the latest upstream version:

    git pull --ff upstream master

Coding Rules

To ensure consistency throughout the source code, keep these rules in mind as you are working:

  • All features or bug fixes must be tested by one or more specs (unit-tests).

  • All public API methods must be documented.

  • We follow [Google's JavaScript Style Guide][js-style-guide], but wrap all code at 100 characters.

    Limited feedback is provided with npm run lint and automatically while committing code using lint-staged and eslint.

Commit Message Format

We have very precise rules over how our Git commit messages must be formatted. This format leads to easier to read commit history.

Each commit message consists of a header, a body, and a footer.

<header>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>

The header is mandatory and must conform to the Commit Message Header format.

The body is mandatory for all commits except for those of type "docs". When the body is present it must be at least 20 characters long and must conform to the Commit Message Body format.

The footer is optional. The Commit Message Footer format describes what the footer is used for and the structure it must have.

Any line of the commit message cannot be longer than 100 characters.

Commit Message Header

<type>(<scope>): <short summary>
  │       │             │
  │       │             └─⫸ Summary in present tense. Not capitalized. No period at the end.
  │       │
  │       └─⫸ Commit Scope: animations|bazel|benchpress|common|compiler|compiler-cli|core|
  │                          elements|forms|http|language-service|localize|platform-browser|
  │                          platform-browser-dynamic|platform-server|router|service-worker|
  │                          upgrade|zone.js|packaging|changelog|dev-infra|docs-infra|migrations|
  │                          ngcc|ve
  │
  └─⫸ Commit Type: build|ci|docs|feat|fix|perf|refactor|test

The <type> and <summary> fields are mandatory, the (<scope>) field is optional.

Type

Must be one of the following:

  • build: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
  • ci: Changes to our CI configuration files and scripts (example scopes: Circle, BrowserStack, SauceLabs)
  • docs: Documentation only changes
  • feat: A new feature
  • fix: A bug fix
  • perf: A code change that improves performance
  • refactor: A code change that neither fixes a bug nor adds a feature
  • test: Adding missing tests or correcting existing tests
Scope

The scope should be the name of the npm package affected (as perceived by the person reading the changelog generated from commit messages).

The following is the list of supported scopes:

  • animations
  • bazel
  • benchpress
  • common
  • compiler
  • compiler-cli
  • core
  • elements
  • forms
  • http
  • language-service
  • localize
  • platform-browser
  • platform-browser-dynamic
  • platform-server
  • router
  • service-worker
  • upgrade
  • zone.js
Summary

Use the summary field to provide a succinct description of the change:

  • use the imperative, present tense: "change" not "changed" nor "changes"
  • don't capitalize the first letter
  • no dot (.) at the end

Commit Message Body

Just as in the summary, use the imperative, present tense: "fix" not "fixed" nor "fixes".

Explain the motivation for the change in the commit message body. This commit message should explain why you are making the change. You can include a comparison of the previous behavior with the new behavior in order to illustrate the impact of the change.

Commit Message Footer

The footer can contain information about breaking changes and is also the place to reference GitHub issues, Jira tickets, and other PRs that this commit closes or is related to.

BREAKING CHANGE: <breaking change summary>
<BLANK LINE>
<breaking change description + migration instructions>
<BLANK LINE>
<BLANK LINE>
Fixes #<issue number>

Breaking Change section should start with the phrase "BREAKING CHANGE: " followed by a summary of the breaking change, a blank line, and a detailed description of the breaking change that also includes migration instructions.

Revert commits

If the commit reverts a previous commit, it should begin with revert: , followed by the header of the reverted commit.

The content of the commit message body should contain:

  • information about the SHA of the commit being reverted in the following format: This reverts commit <SHA>,
  • a clear description of the reason for reverting the commit message.
