Conventional Commits

Format all commit messages according to the Conventional Commits specification. This enables automated changelog generation, semantic versioning, and better commit history.

Format Structure

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

Commit Types

Required Types

  • feat: - A new feature (correlates with MINOR in Semantic Versioning)
  • fix: - A bug fix (correlates with PATCH in Semantic Versioning)

Common Additional Types

  • docs: - Documentation only changes
  • style: - Code style changes (formatting, missing semicolons, etc.)
  • refactor: - Code refactoring without bug fixes or new features
  • perf: - Performance improvements
  • test: - Adding or updating tests
  • build: - Build system or external dependencies changes
  • ci: - CI/CD configuration changes
  • chore: - Other changes that don't modify src or test files
  • revert: - Reverts a previous commit

Scope

An optional scope provides additional contextual information about the section of the codebase:

feat(parser): add ability to parse arrays
fix(auth): resolve token expiration issue
docs(readme): update installation instructions

Description

  • Must immediately follow the colon and space after the type/scope
  • Use imperative mood ("add feature" not "added feature" or "adds feature")
  • Don't capitalize the first letter
  • No period at the end
  • Keep it concise (typically 50-72 characters)

Body

  • Optional longer description providing additional context
  • Must begin one blank line after the description
  • Can consist of multiple paragraphs
  • Explain the "what" and "why" of the change, not the "how"

Breaking Changes

Breaking changes can be indicated in two ways:

1. Using ! in the type/scope

feat!: send an email to the customer when a product is shipped
feat(api)!: send an email to the customer when a product is shipped

2. Using BREAKING CHANGE footer

feat: allow provided config object to extend other configs

BREAKING CHANGE: `extends` key in config file is now used for extending other config files

3. Both methods

chore!: drop support for Node 6

BREAKING CHANGE: use JavaScript features not available in Node 6.

Examples

Simple feature

feat: add user authentication

Feature with scope

feat(auth): add OAuth2 support

Bug fix with body

fix: prevent racing of requests

Introduce a request id and a reference to latest request. Dismiss
incoming responses other than from latest request.

Remove timeouts which were used to mitigate the racing issue but are
obsolete now.

Breaking change

feat!: migrate to new API client

BREAKING CHANGE: The API client interface has changed. All methods now
return Promises instead of using callbacks.

Documentation update

docs: correct spelling of CHANGELOG

Multi-paragraph body with footers

fix: prevent racing of requests

Introduce a request id and a reference to latest request. Dismiss
incoming responses other than from latest request.

Remove timeouts which were used to mitigate the racing issue but are
obsolete now.

Guidelines

  1. Always use a type - Every commit must start with a type followed by a colon and space
  2. Use imperative mood - Write as if completing the sentence "If applied, this commit will..."
  3. Be specific - The description should clearly communicate what changed
  4. Keep it focused - One logical change per commit
  5. Use scopes when helpful - Scopes help categorize changes within a codebase
  6. Document breaking changes - Always indicate breaking changes clearly

Semantic Versioning Correlation

  • fix: → PATCH version bump (1.0.0 → 1.0.1)
  • feat: → MINOR version bump (1.0.0 → 1.1.0)
  • BREAKING CHANGE → MAJOR version bump (1.0.0 → 2.0.0)

When to Use

Use this format for:

  • All git commits
  • Commit message generation
  • Pull request merge commits
  • When the user asks about commit messages or git commits

Common Mistakes to Avoid

❌ Added new feature (past tense, capitalized) ✅ feat: add new feature (imperative, lowercase)

❌ fix: bug (too vague) ✅ fix: resolve null pointer exception in user service

❌ feat: add feature (redundant) ✅ feat: add user profile page

❌ feat: Added OAuth support. (past tense, period) ✅ feat: add OAuth support
