We'd love for you to contribute to our source code and to make AngularJS even better than it is today! Here are the guidelines we'd like you to follow:
Help us keep AngularJS open and inclusive. Please read and follow our Code of Conduct.
If you have questions about how to use AngularJS, please direct these to the Google Group discussion list or StackOverflow. We are also available on IRC and Gitter.
If you find a bug in the source code or a mistake in the documentation, you can help us by submitting an issue to our GitHub Repository. Even better you can submit a Pull Request with a fix.
Localization Issues: AngularJS uses the Google Closure I18N library to generate its own I18N files (the ngLocale module). This means that any changes to these files would be lost the next time that we import the library. Since the Closure library i18n data is itself auto-generated from the data of the Common Locale Data Repository (CLDR) project, errors in the data should be reported there. See also the Closure guide to i18n changes.
Please see the Submission Guidelines below.
You can request a new feature by submitting an issue to our GitHub Repository. If you would like to implement a new feature then consider what kind of change it is:
If you want to help improve the docs, it's a good idea to let others know what you're working on to minimize duplication of effort. Create a new issue (or comment on a related existing one) to let others know what you're working on.
For large fixes, please build and test the documentation before submitting the PR to be sure you haven't accidentally introduced any layout or formatting issues. You should also make sure that your commit message starts with "docs" and follows the Commit Message Guidelines outlined below.
If you're just making a small change, don't worry about filing an issue first. Use the friendly blue "Improve this doc" button at the top right of the doc page to fork the repository in-place and make a quick change on the fly. When naming the commit, it is advised to follow the commit message guidelines below, by starting the commit message with docs and referencing the filename. Since this is not obvious and some changes are made on the fly, this is not strictly necessary and we will understand if this isn't done the first few times.
Before you submit your issue search the archive, maybe your question was already answered.
If your issue appears to be a bug, and hasn't been reported, open a new issue. Help us to maximize the effort we can spend fixing issues and adding new features, by not reporting duplicate issues. Providing the following information will increase the chances of your issue being dealt with quickly:
Here is a great example of a well defined issue: https://github.com/angular/angular.js/issues/5069
If you get help, help others. Good karma rulez!
Before you submit your pull request consider the following guidelines:
Make your changes in a new git branch:
shell
git checkout -b my-fix-branch master
Create your patch, including appropriate test cases.
Commit your changes using a descriptive commit message that follows our
commit message conventions and passes our commit message presubmit hook
(validate-commit-msg.js
). Adherence to the commit message conventions is required,
because release notes are automatically generated from these messages.
shell
git commit -a
Note: the optional commit -a
command line option will automatically "add" and "rm" edited files.
Build your changes locally to ensure all the tests pass:
shell
grunt test
Push your branch to GitHub:
shell
git push origin my-fix-branch
In GitHub, send a pull request to angular.js:master
.
If we suggest changes, then:
my-fix-branch
).If the PR gets too outdated we may ask you to rebase and force push to update the PR:
git rebase master -i
git push origin my-fix-branch -f
WARNING: Squashing or reverting commits and force-pushing thereafter may remove GitHub comments on code that were previously made by you or others in your commits. Avoid any form of rebasing unless necessary.
That's it! Thank you for your contribution!
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:
shell
git push origin --delete my-fix-branch
Check out the master branch:
shell
git checkout master -f
Delete the local branch:
shell
git branch -D my-fix-branch
Update your master with the latest upstream version:
shell
git pull --ff upstream master
To ensure consistency throughout the source code, keep these rules in mind as you are working:
We have very precise rules over how our git commit messages can be formatted. This leads to more readable messages that are easy to follow when looking through the project history. But also, we use the git commit messages to generate the AngularJS change log.
The commit message formatting can be added using a typical git workflow or through the use of a CLI
wizard (Commitizen). To use the wizard, run yarn run commit
in your terminal after staging your changes in git.
Each commit message consists of a header, a body and a footer. The header has a special format that includes a type, a scope and a subject:
<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>
The header is mandatory and the scope of the header is optional.
Any line of the commit message cannot be longer 100 characters! This allows the message to be easier to read on GitHub as well as in various git tools.
If the commit reverts a previous commit, it should begin with revert:
, followed by the header of the reverted commit.
In the body it should say: This reverts commit <hash>.
, where the hash is the SHA of the commit being reverted.
Must be one of the following:
The scope could be anything specifying place of the commit change. For example $location
,
$browser
, $compile
, $rootScope
, ngHref
, ngClick
, ngView
, etc...
You can use *
when the change affects more than a single scope.
The subject contains succinct description of the change:
Just as in the subject, use the imperative, present tense: "change" not "changed" nor "changes". The body should include the motivation for the change and contrast this with previous behavior.
The footer should contain any information about Breaking Changes and is also the place to reference GitHub issues that this commit closes.
Breaking Changes should start with the word BREAKING CHANGE:
with a space or two newlines.
The rest of the commit message is then used for this.
