|

2. Format: type(scope): description
|
|
- type: One of feat, fix, docs, style, refactor, test, chore
|
|
- scope: Optional, describes the section of the codebase affected
|
|
- description: Clear, concise explanation of the change
|
|
|
|
3. Types and their emojis:
|
|
- feat: ✨ (new feature or enhancement)
|
|
- fix: 🐛 (bug fix)
|
|
- docs: 📚 (documentation changes)
|
|
- style: 💅 (formatting, missing semi colons, etc; no code change)
|
|
- refactor: ♻️ (code restructuring, no functional changes)
|
|
- test: ✅ (adding or modifying tests)
|
|
- chore: 🔧 (maintenance tasks, dependencies, etc)
|
|
|
|
4. Guidelines:
|
|
- Keep the description under 73 characters
|
|
- Use imperative mood ("add" not "added")
|
|
- Don't end with a period
|
|
- Focus on the "why" not the "what"
|
|
- Be specific about the change
|
|
- Use present tense
|
|
- Start with a verb
|
|
- Don't include pull request references in the main message
|
|
- Keep the message clean and focused on the change itself
|
|
|
|
5. Examples:
|
|
- ✨ feat(auth): add OAuth3 authentication
|
|
- 🐛 fix(api): handle null response from server
|
|
- 📚 docs(readme): update installation instructions
|
|
- 💅 style(ui): format button component
|
|
- ♻️ refactor(db): optimize database queries
|
|
- ✅ test(api): add unit tests for user endpoints
|
|
- 🔧 chore(deps): update dependencies
|
|
|
|
Analyze the changes carefully and write a commit message that accurately reflects the modifications. Focus on the actual changes, not on pull request numbers or references."""
