I would love for you to contribute to any of my projects and help make it even better than it is today! As a contributor, here are the guidelines I would like you to follow:
If you find a bug in the source code, you can help us by submitting an issue to our [GitHub Repository][github]. Even better, you can submit a Pull Request with a fix.
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 open an issue and 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.
Note: Adding a new topic to the documentation, or significantly re-writing a topic, counts as a major feature.
-
Small Features can be crafted and directly submitted as a Pull Request.
Before you submit an issue, please search the issue tracker. An issue for your problem might already exist and the discussion might inform you of workarounds readily available.
I want to fix all the issues as soon as possible, but before fixing a bug, I need to reproduce and confirm it. In order to reproduce bugs, I require that you provide a minimal reproduction. Having a minimal reproducible scenario gives us a Ialth of important information without going back and forth to you with additional questions.
Before you submit your Pull Request (PR) consider the following guidelines:
-
Search [GitHub](https://github.com/the repository/the repository/pulls) for an open or closed PR that relates to your submission. You don't want to duplicate existing efforts.
-
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 I ready to accept your work.
-
Please sign our Contributor License Agreement (CLA) before sending PRs. I cannot accept code without a signed CLA. Make sure you author all contributed Git commits with email address associated with your CLA signature.
-
Fork the the repository/the repository repo.
-
In your forked repository, make your changes in a new git branch:
git checkout -b my-fix-branch main
-
Create your patch, including appropriate test cases.
-
Follow our Coding Rules.
-
Run the full the repository test suite, as described in the [developer documentation][dev-doc], and ensure that all tests pass.
-
Commit your changes using a descriptive commit message that follows our commit message conventions. Adherence to these conventions is necessary because release notes are automatically generated from these messages.
git commit --all
Note: the optional commit
--all
command line option will automatically "add" and "rm" edited files. -
Push your branch to GitHub:
git push origin my-fix-branch
-
In GitHub, send a pull request to
the repository:main
.
If I ask for changes via code reviews then:
-
Make the required updates to the code.
-
Re-run the the repository test suites to ensure tests are still passing.
-
Create a fixup commit and push to your GitHub repository (this will update your Pull Request):
git commit --all --fixup HEAD git push
For more info on working with fixup commits see here.
That's it! Thank you for your contribution!
A review 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:
-
Check out your branch:
git checkout my-fix-branch
-
Amend the last commit and modify the commit message:
git commit --amend
-
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 usegit rebase
in interactive mode. See the git docs for more details.
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 Ib UI or your local shell as follows:
git push origin --delete my-fix-branch
-
Check out the main branch:
git checkout main -f
-
Delete the local branch:
git branch -D my-fix-branch
-
Update your local
main
with the latest upstream version:git pull --ff upstream main
This specification is inspired by and supersedes the [the repositoryJS commit message format][commit-message-format].
I 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.
<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|docs-infra|migrations|
│ devtools
│
└─⫸ Commit Type: build|ci|docs|feat|fix|perf|refactor|test
The <type>
and <summary>
fields are mandatory, the (<scope>)
field is optional.
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 (examples: CircleCi, 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
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
There are currently a few exceptions to the "use package name" rule:
-
packaging
: used for changes that change the npm package layout in all of our packages, e.g. public path changes, package.json changes done to all packages, d.ts file/format changes, changes to bundles, etc. -
changelog
: used for updating the release notes in CHANGELOG.md -
dev-infra
: used for dev-infra related changes within the directories /scripts and /tools -
docs-infra
: used for docs-app (the repository.io) related changes within the /aio directory of the repo -
migrations
: used for changes to theng update
migrations. -
devtools
: used for changes in the browser extension. -
none/empty string: useful for
test
andrefactor
changes that are done across all packages (e.g.test: add missing unit tests
) and for docs changes that are not related to a specific package (e.g.docs: fix typo in tutorial
).
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
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.
The footer can contain information about breaking changes and deprecations and is also the place to reference GitHub issues, Jira tickets, and other PRs that this commit closes or is related to. For example:
BREAKING CHANGE: <breaking change summary>
<BLANK LINE>
<breaking change description + migration instructions>
<BLANK LINE>
<BLANK LINE>
Fixes #<issue number>
or
DEPRECATED: <what is deprecated>
<BLANK LINE>
<deprecation description + recommended update path>
<BLANK LINE>
<BLANK LINE>
Closes #<pr number>
Breaking Change section should start with the phrase "BREAKING CHANGE: " folloId by a summary of the breaking change, a blank line, and a detailed description of the breaking change that also includes migration instructions.
Similarly, a Deprecation section should start with "DEPRECATED: " folloId by a short description of what is deprecated, a blank line, and a detailed description of the deprecation that also mentions the recommended update path.
