Contributing to AngularJS Material

Code of Conduct

Please help us keep AngularJS Material open and inclusive by reading and following our Code of Conduct.

We are care deeply about our inclusive community and diverse group of members. As part of this, we do take time away from development to enforce this policy through interventions in heated discussions, one on one discussions to explain the policy to violators, and bans for repeat violators.

Have a Question, Problem, or Idea?

If you have questions or ideas regarding AngularJS Material, please direct these to the AngularJS Material Forum.

Otherwise, do you:

1. Want to report a Bug or Issue?

If you find a bug in the source code or a mistake in the documentation, we recommend that you first review the latest master version of the Online Documentation and use one of the Demos to create a CodePen that reproduces the issue.

If the issue can be reproduced in the latest master version, you can help us by submitting an issue to our GitHub Repository. After the issue is triaged (labels are applied to it), we invite you to submit a Pull Request with a proposed fix. Your custom changes can be crafted in a repository fork and submitted to the GitHub Repository as a Pull Request.

Important: Please review the Submission Guidelines below, before contributing to the project.

2. Want to request an Enhancement?

You can request an enhancement by submitting an issue. After an issue is submitted, if you would like to implement an enhancement then consider what kind of change it is:

  • Major Changes that you wish to contribute to the project should be discussed first on our AngularJS Material Forum, so that we can 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 Changes can be crafted and submitted to the GitHub Repository as a Pull Request.

Issue Guidelines

Please note, this project is mature and stable with thousands of projects depending upon it.

We welcome your enhancement requests, doc improvements, and issue reports. However, we are not accepting major feature requests at this time.

If you're thinking of contributing code or documentation to the project, please review Submitting Pull Requests before beginning any work.

Submitting an Issue

Before you submit an issue, search the issues archive; maybe the issue has already been submitted or considered. If the issue appears to be a bug, and hasn't been reported, open a new issue.

Please do not report duplicate issues; help us maximize the effort we can spend fixing issues and adding enhancements.

Providing the following information will increase the chances of your issue being dealt with quickly:

  • Issue Title - provide a concise issue title prefixed with a snake-case name of the associated service or component (if any): <component>: <issue title>. Adding the md- prefix should be avoided.


    • menu-bar: does not support dark mode themes #11238
    • tooltip: memory leak on destroy #11133
  • Complete the full Issue Template - GitHub now supports issue templates and AngularJS Material provides one to make submitting an issue with all of the required information more straightforward.

  • Suggest a Fix - if you can't fix the bug yourself, perhaps you can point to what might be causing the problem (line of code or commit).

Submitting Pull Requests

Important: We are not accepting major feature requests or PRs that contain major new features or breaking changes at this time.

Please check with us via the discussion forum before investing significant effort in a planned Pull Request submission; it's possible that we are already working on a related PR or have decided that the enhancement does not belong in the core AngularJS Material project.

Git Commit Guidelines

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.

It is important to note that we use the git commit messages to generate the AngularJS Material CHANGELOG document. Improperly formatted commit messages may result in your change not appearing in the CHANGELOG of the next release.

Commit Message Format

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>

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.


Must be one of the following:

  • feat: A new feature
  • fix: A bug fix
  • docs: Documentation only changes
  • style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
  • refactor: A code change that neither fixes a bug nor adds a feature
  • perf: A code change that improves performance
  • test: Adding missing tests
  • chore: Changes to the build process or auxiliary tools and libraries such as documentation generation

The scope could be anything that helps specifying the scope (or feature) that is changing.


  • select(multiple):
  • dialog(alert):

The subject contains a succinct description of the change:

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

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, Fixes, or Relates to.

Breaking Changes are intended to be highlighted in the ChangeLog as changes that will require community users to modify their code after updating to a version that contains this commit.

Sample Commit messages:
fix(autocomplete): don't show the menu panel when readonly

this could sometimes happen when no value was selected

Fixes #11231
feat(chips): trigger ng-change on chip addition/removal

* add test of `ng-change` for `md-chips`
* add docs regarding `ng-change` for `md-chips` and `md-contact-chips`
* add demo for ng-change on `md-chips`

Fixes #11161 Fixes #3857
refactor(content): prefix mdContent scroll- attributes

    BREAKING CHANGE: md-content's `scroll-` attributes are now prefixed with `md-`.

    Change your code from this:

    <md-content scroll-x scroll-y scroll-xy>

    To this:

    <md-content md-scroll-x md-scroll-y md-scroll-xy>

Guidelines for Developer Commit Authorizations
