Contributing to Material Design Components for Angular

Code of Conduct

Help us keep Angular open and inclusive. Please read and follow our Code of Conduct.

Found an Issue?

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.

Submission Guidelines

We're still in early development but we look forward to welcoming community contributions soon.

Javascript Conventions

  • 2 spaces for tabs
  • Each component declares its own module at the top and leaks no variables
  • Use the 'revealing pattern' when possible. API at top, function definitions at bottom. See src/components/checkbox/checkbox.js
  • JSHint conventions in progress

Testing Conventions

  • For testing, use beforeEach loops and global variables as little as possible.

    • Each test should have its own isolated logic, to make tests easier to read and more portable.

  • For an example of the desired directive testing pattern, see src/components/checkbox/checkbox.spec.js

    • Create a setup(attrs) function which takes attributes to put on the directive
    • The setup function should register the module for the test and return the compiled directive element.
    • Use el.scope() and el.isolateScope() to access the element's scope.

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. But also, we use the git commit messages to generate the AngularDart change log.

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

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.

Type

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 or 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

Scope

The scope could be anything specifying place of the commit change.

Subject

The subject contains 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

###Body 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.

###Footer The footer should contain any information about Breaking Changes and is also the place to reference GitHub issues that this commit Closes.
