Commit Message Format

• A commit message consists of a header, body and footer.
• The header has a type and a subject:

{{type}}: {{subject}}
<BLANK LINE>
{{body}}
<BLANK LINE>
{{breaking changes}}
<BLANK LINE>
{{footer}}

The header is the only mandatory part of the commit message.

The first line (type + subject) is limited to 50 characters [enforced]

Any other line should be limited to 72 character [automatic wrapping]

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: Markup-only changes (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 or updating tests.
• chore: Build process or auxiliary tool changes.
• ci: CI related changes.

Subject

The subject contains succinct description of the change:

• Use the imperative, present tense: "change" not "changed" nor "changes"
• 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.

Affects [only on lerna environments]

Select the packages the commit affected.

Breaking Changes

Breaking Changes must start with the words BREAKING CHANGE: .

Footer

The footer is the place to reference any tasks related to this commit.
