Commit Message Style Guide

Commit Message Structure

A commit message should consist of two distinct parts separated by a blank line: the title and an optional body. The layout looks like this:

type: subject

body

Title

The title should consist of the type of the change and subject separated by a colon :. Title should be no longer than 50 characters.

Type

The type is contained within the title and can be one of these types:

• feat: a new feature
• fix: a bug fix
• docs: changes to documentation
• style: formatting, missing semi colons, etc; no code change
• refactor: refactoring production code
• test: adding tests, refactoring test; no production code change
• chore: updating build tasks, package manager configs, etc; no production code change

Subject

Should begin with a capital letter and not end with a period.

Use an imperative tone to describe what a commit does, rather than what it did. For example, use change; not changed or changes.

Body

If the changes made in a commit are complex, they should be explained in the commit body. Use the body to explain the what and why of a commit, not the how.

When writing a body, the blank line between the title and the body is required and you should limit the length of each line to no more than 72 characters.

Examples

Without body

docs: update screenshots in the documentation

or

With body
